If you already own a home with significant equity, you may be sitting on the money you need for the down payment on your next house.

The problem is that your equity isn’t sitting in a checking account.

It’s tied up in your current home.

That creates a common challenge for homeowners who want to move:

How do you use the equity in your current home to buy the next one if you haven’t sold yet?

One possible solution is a Home Equity Line of Credit (HELOC).

In many situations, homeowners can use funds from a HELOC for the down payment and closing costs on another home. This can make it possible to buy before selling instead of waiting until the current home closes before having access to its equity.

But there’s an important catch.

Taking money from a HELOC doesn’t simply turn home equity into cash. You’re borrowing against your current property, and the resulting HELOC payment can affect your debt-to-income ratio when qualifying for the new mortgage.

So the real question isn’t just:

“Can I use a HELOC for a down payment?”

It’s:

“Can I use a HELOC for the down payment and still qualify for the new mortgage?”

Those are two very different questions.

What Is a HELOC?

A Home Equity Line of Credit, commonly called a HELOC, is a revolving line of credit secured by the equity in your home.

Instead of receiving one fixed loan amount and immediately making payments on the entire balance, a HELOC generally provides an approved credit limit that you can draw from as needed during the applicable draw period.

For example, suppose your HELOC has a:

$100,000 credit limit

You might initially draw only:

$60,000

to help purchase your next home.

The remaining available credit generally stays unused unless you need it later, subject to the terms of the HELOC.

That’s one reason HELOCs can provide homeowners with flexibility when they’re trying to coordinate the purchase of one home with the sale of another.

HELOCs are commonly used for things such as:

• Home improvements
• Major expenses
• Debt consolidation
• Accessing home equity without refinancing the existing first mortgage
• Down payments and closing costs on another property

For someone planning a move, that last use can be particularly valuable.

Can You Use a HELOC for a Down Payment on Another House?

In many cases, yes.

Borrowed funds secured by another asset can potentially be used toward the funds required to purchase a home, subject to the requirements of the mortgage program and lender.

That means a homeowner may be able to borrow against the equity in their current residence and use those funds toward the purchase of another property.

For example:

Current home value: $500,000

Current mortgage balance: $250,000

Estimated equity: $250,000

That doesn’t necessarily mean the homeowner can borrow the entire $250,000.

The amount available through a HELOC will depend on factors such as the property’s value, existing mortgage balance, the HELOC lender’s maximum combined loan-to-value requirements, credit and other qualification requirements.

But let’s say the homeowner qualifies for a $100,000 HELOC.

They could potentially draw:

$75,000

and use those funds toward the down payment and eligible closing expenses on the next home.

Instead of having to sell first to unlock the equity, the homeowner has created access to some of that equity before the sale occurs.

Why Would Someone Use a HELOC to Buy Another Home?

The biggest reason is usually timing.

Imagine you’ve found the house you want to buy, but your current home hasn’t sold yet.

Maybe it isn’t even listed.

You know you have plenty of equity, but most of your available cash is tied up in the property.

Without another strategy, you might have to:

1. Sell your current home.
2. Complete that closing.
3. Receive the proceeds.
4. Then use those proceeds toward your next purchase.

That can work.

But it can also create practical problems.

Where do you live between closings?

What happens if the home you want becomes available before you’re ready to sell?

Do you make your purchase offer contingent upon the sale of your existing home?

And how competitive will that offer be if the seller has another buyer who doesn’t need to sell a home first?

A HELOC can sometimes help separate those two transactions.

Instead of needing the sale proceeds before purchasing, you may be able to access a portion of your existing equity and use it to complete the next purchase.

Then, when the existing property sells, the proceeds can potentially be used to pay off the HELOC along with the existing mortgage.

Example: Using a HELOC to Buy Before Selling

Here’s a simplified example.

Suppose you own a home worth approximately:

$450,000

Your existing mortgage balance is:

$200,000

You want to purchase your next home for:

$500,000

and would like to put:

$100,000 down

You have sufficient equity in your existing home but don’t have $100,000 sitting in liquid savings.

If you qualify for an appropriately sized HELOC, you might be able to access the funds needed for the down payment before your existing property sells.

The sequence could look something like this:

Current Home

Estimated value: $450,000
Mortgage balance: $200,000
HELOC draw: $100,000

New Home

Purchase price: $500,000
Down payment: $100,000
New first mortgage: $400,000

You purchase the new property.

Your old home is subsequently sold.

At closing, the existing first mortgage and HELOC are generally paid from the sale proceeds, with the remaining equity going to you after other applicable costs.

This can provide considerably more flexibility than having to coordinate two closings on exactly the same day.

But there’s an extremely important part of this example we haven’t addressed yet:

Can you qualify while carrying the old mortgage, the HELOC payment, and the new housing payment?

That’s where mortgage planning becomes critical.

A HELOC Gives You Access to Equity—It Doesn’t Eliminate the Debt

This is probably the most important concept to understand.

If you have $250,000 of equity and borrow $100,000 against it, you haven’t simply converted $100,000 of equity into free cash.

You’ve created a $100,000 debt secured by your current home.

Depending on the HELOC terms and applicable mortgage guidelines, the payment associated with that debt may need to be considered when you’re qualifying for the new mortgage.

You may also still have the existing mortgage payment on your current residence.

Then we’re adding the proposed housing payment for the home you’re purchasing.

That’s why a homeowner can have tremendous equity and still run into a mortgage qualification issue.

The problem isn’t necessarily assets.

It can be monthly obligations.

How Does a HELOC Affect Your Debt-to-Income Ratio?

Your debt-to-income ratio (DTI) compares the monthly obligations used for mortgage qualification with your qualifying monthly income.

If a HELOC requires a monthly payment, that obligation can generally affect the calculation for the new mortgage.

For example, suppose your qualifying monthly income is:

$12,000

Before using the HELOC, your applicable monthly obligations plus the proposed new housing payment total:

$4,800

That would produce a DTI of:

40%

Now suppose accessing the equity creates a:

$600 monthly HELOC payment

Your total monthly obligations become:

$5,400

$5,400 ÷ $12,000 = 45% DTI

The HELOC gave you the cash needed for the down payment.

But it also increased your DTI by five percentage points.

That doesn’t automatically mean the mortgage won’t work.

It means the HELOC needs to be considered as part of the mortgage strategy before you draw the money.

The Existing Mortgage Can Matter Too

The HELOC isn’t necessarily the only additional obligation.

If you still own your current residence when purchasing the next home, your existing housing expense may also need to be considered when determining mortgage qualification.

That can leave a homeowner temporarily dealing with some combination of:

• Existing first mortgage
• HELOC payment
• New mortgage payment
• Property taxes
• Homeowners insurance
• Other monthly debts

Depending on the circumstances and mortgage program, there may be ways the existing residence is treated differently when it is under contract for sale or when other applicable requirements are satisfied.

But you shouldn’t simply assume:

“I’m selling that house anyway, so the lender won’t count the payment.”

The timing and documentation of the sale can matter.

This is one reason getting a thorough mortgage pre-approval before deciding how to access your equity can be so valuable.

The goal isn’t merely to find a source for the down payment.

It’s to structure the entire move so that the down payment, existing property, HELOC, and new mortgage all work together.

How Much Can You Borrow With a HELOC?

The amount you can access through a HELOC depends on several factors, including:

• The current value of your home
• Your existing mortgage balance
• The HELOC lender’s maximum combined loan-to-value ratio
• Your credit profile
• Your income and debts
• The lender’s individual HELOC guidelines

One of the most important numbers is the combined loan-to-value ratio, commonly called CLTV.

CLTV compares the total debt secured by the property with the property’s value.

For example:

Estimated home value: $500,000
Current first mortgage: $250,000
Proposed HELOC: $100,000
Total mortgage debt: $350,000

$350,000 ÷ $500,000 = 70% CLTV

The homeowner would still have approximately $150,000 of equity that isn’t financed.

But the maximum HELOC available isn’t simply:

Home value − mortgage balance = amount you can borrow

The HELOC lender determines how much of the home’s value it is willing to lend against.

That’s why someone with $250,000 in equity might qualify for considerably less than a $250,000 HELOC.

Do You Need to Draw the Entire HELOC?

Not necessarily.

One of the advantages of a HELOC is that it’s generally structured as a line of credit rather than a traditional lump-sum loan.

Suppose you’re approved for:

$125,000

but only need:

$70,000

for your down payment and closing expenses.

Depending on the HELOC terms, you may be able to draw the $70,000 you need rather than borrowing the entire $125,000.

That distinction matters because the amount you actually borrow can affect the payment associated with the HELOC.

It also means the HELOC can potentially provide a financial cushion during the transition without requiring you to borrow every available dollar.

However, you should understand the HELOC’s specific terms, including any minimum initial draw, fees, variable interest rate, draw period and repayment requirements.

When Should You Open the HELOC?

This is something homeowners should think about before listing or selling their current home.

A HELOC is secured by the property you’re borrowing against.

If you’re planning to use the equity in your existing residence to help purchase another home, waiting until the current property is already under contract—or until you’re days away from needing the money—can complicate the strategy.

Ideally, the HELOC should be discussed as part of the overall buy-before-you-sell strategy well in advance.

That gives you time to determine:

• How much equity may be available
• How much cash you’ll actually need
• What the HELOC payment could be
• How that payment affects DTI
• Whether you’ll qualify while carrying the existing property
• Whether a HELOC is actually the best financing tool for the transaction

The fact that you can access your equity doesn’t necessarily mean a HELOC is the best way to do it.

HELOC vs. Bridge Loan: What’s the Difference?

A bridge loan and a HELOC can both potentially help homeowners access equity before selling their current residence.

But they aren’t the same product.

A HELOC is a revolving line of credit secured by your existing home. It may be opened well before you purchase another property and can provide flexibility in how much you draw.

A bridge loan is generally designed specifically to help bridge the financial gap between purchasing the next property and selling the existing one.

Here’s a simplified comparison:

	HELOC	Bridge Loan
Uses current-home equity	Yes	Yes
Can help fund next-home purchase	Yes	Yes
Revolving credit line	Typically yes	Typically no
Designed specifically for short-term transition	Not necessarily	Generally yes
May remain available beyond home purchase	Potentially	Generally short-term
Existing home is collateral	Yes	Typically yes
Qualification requirements apply	Yes	Yes

The better choice depends on the situation.

For someone who already has an established HELOC with sufficient available credit, using it may be relatively straightforward.

For someone who needs to access a larger portion of their equity specifically to facilitate a move, a bridge loan may deserve consideration.

The costs, interest rates, repayment structure, available equity, qualification requirements and expected timeline for selling the existing property all matter.

HELOC vs. Cash-Out Refinance

A cash-out refinance is another way to access home equity, but it works very differently.

With a cash-out refinance, the existing first mortgage is generally replaced with a larger new mortgage, and the homeowner receives a portion of the equity as cash.

A HELOC usually leaves the existing first mortgage in place and adds a separate line of credit secured by the property.

That difference can be extremely important for homeowners who already have a low interest rate on their current mortgage.

Imagine your current first mortgage has a rate of:

3.00%

Replacing that mortgage with a much larger cash-out refinance at today’s market rate solely to access short-term equity for a move might not be attractive.

A HELOC could potentially allow you to preserve the existing first mortgage while borrowing only the amount of equity you need.

Of course, if you’re planning to sell the property soon anyway, the analysis is somewhat different.

The important point is that accessing equity doesn’t automatically mean refinancing your entire first mortgage.

HELOC vs. Selling First

The simplest way to access all of the available equity in your current home is usually to sell it.

Once the property closes, the existing mortgage and other liens are paid, and the remaining proceeds become available to you.

From a financing perspective, selling first can simplify things considerably.

You may eliminate:

• The existing mortgage payment
• The need for a HELOC
• The temporary HELOC payment
• The challenge of qualifying with multiple housing obligations

You may also have substantially more cash available for the new purchase.

But selling first introduces another problem:

You no longer own your current home.

If you haven’t already purchased the next property, you may need temporary housing.

You might also feel pressure to purchase quickly because you’ve already sold.

That’s why the mathematically simplest option isn’t necessarily the most convenient option.

For some homeowners, accessing equity through a HELOC or other financing strategy provides the flexibility to find the right next home before giving up the current one.

What About Making an Offer Contingent Upon Selling Your Current Home?

Another option is to make the purchase contract contingent upon the sale of your existing property.

This can reduce the need to access equity before selling because the transactions can be coordinated around the existing home’s sale.

The downside is that a home-sale contingency can make an offer less attractive to a seller.

Imagine a seller receives two otherwise similar offers.

Buyer A:
Can purchase without selling another property first.

Buyer B:
Needs to sell their existing home before completing the purchase.

From the seller’s perspective, Buyer A may represent fewer moving pieces and less uncertainty.

That doesn’t mean contingent offers can’t get accepted.

They absolutely can.

Market conditions, price, other terms and the status of the buyer’s existing home all matter.

But for homeowners trying to make a stronger offer, having the ability to purchase without a home-sale contingency can sometimes be valuable.

A HELOC or bridge-financing strategy may help accomplish that—but only if the borrower can qualify appropriately.

Could You Use a Smaller Down Payment Instead?

This is an option that sometimes gets overlooked.

Suppose you were planning to use:

$100,000

of existing home equity for the down payment on the next property.

But what if the new mortgage doesn’t actually require a $100,000 down payment?

Depending on the mortgage program and your financial profile, you may have the ability to purchase with a smaller down payment.

For example, rather than borrowing $100,000 against your current home, perhaps the transaction works with:

$50,000 down

That could mean:

• A smaller HELOC draw
• A smaller HELOC payment
• More remaining available equity
• Less short-term debt
• Potentially easier qualification

There can be tradeoffs.

A smaller down payment may result in a larger new mortgage payment and could introduce mortgage insurance depending on the loan structure.

So again, this isn’t automatically better.

But it illustrates why the question shouldn’t be:

“How much equity can I borrow?”

It should be:

“How much equity do I actually need to borrow to make the entire transaction work?”

What Happens to the HELOC When You Sell Your Current Home?

Because the HELOC is secured by your current property, it generally needs to be satisfied when that property is sold.

Here’s a simplified example:

Sale price: $500,000
First mortgage payoff: $240,000
HELOC payoff: $80,000

Before considering commissions, taxes, title charges and other selling expenses, that leaves:

$180,000

of remaining gross equity.

This is why it’s important to account for the HELOC when estimating how much money you’ll ultimately receive from the sale.

If you borrowed $80,000 from the home’s equity to purchase the next property, that $80,000 hasn’t disappeared.

It generally gets repaid from the sale proceeds.

Can You Use the Sale Proceeds to Pay Down the New Mortgage?

Potentially, yes.

This creates another planning opportunity.

Suppose you purchase the next home before selling and use a HELOC for part of the down payment.

After the old property sells and its mortgage and HELOC are paid off, you may still receive substantial remaining proceeds.

Depending on your new mortgage and lender requirements, you may choose to use some of those proceeds to reduce the principal balance of the new loan.

In some situations, a mortgage recast may then allow the lender to recalculate the monthly principal-and-interest payment based on the lower outstanding balance without requiring a full refinance.

For example:

Original new mortgage: $450,000

After selling the previous home, you apply:

$100,000

toward the new mortgage.

New principal balance:

Approximately $350,000

If the mortgage is eligible for a recast and the servicer permits it, the payment may be recalculated using the lower balance while generally retaining the existing interest rate and remaining loan term.

This can create an interesting strategy:

Buy → Sell → Apply Equity → Recast

Instead of needing every dollar of equity available before purchasing, the homeowner may be able to buy first and then restructure the payment after the old property sells.

Whether that strategy works depends on the mortgage product, servicer requirements and your specific financial situation.

But it’s another reason buying before selling doesn’t necessarily mean you’re stuck permanently with the mortgage structure you used to complete the initial purchase.

What Are the Risks of Using a HELOC to Buy Another Home?

Using a HELOC for a down payment can solve a very real problem, but it isn’t free money and it isn’t automatically the right strategy for every homeowner.

Before borrowing against your current home’s equity, you should understand what happens if the transition doesn’t go exactly according to plan.

The biggest risks usually involve:

• Carrying multiple housing payments
• Variable HELOC interest rates
• Taking longer than expected to sell
• Selling the current home for less than expected
• Reducing the equity you’ll receive at closing
• Increasing your debt-to-income ratio
• Taking on more monthly debt than you’re comfortable carrying

For someone with substantial equity, strong income and a relatively predictable sale timeline, those risks may be manageable.

For someone whose mortgage qualification is already tight, using a HELOC could actually make purchasing the next home more difficult.

What Happens If Your Current Home Takes Longer to Sell?

This is one of the most important questions to ask before using a HELOC as part of a buy-before-selling strategy.

Suppose your plan assumes the current home will sell within 30 days.

Instead, it takes four months.

During that period, you could potentially be responsible for:

Current home:

• Existing mortgage payment
• Property taxes
• Homeowners insurance
• HELOC payment
• Utilities and maintenance

New home:

• New mortgage payment
• Property taxes
• Homeowners insurance
• Utilities and maintenance

Even if you qualify for all of those obligations from an underwriting standpoint, you need to consider whether you’re personally comfortable carrying them.

That’s why I like to look beyond simply:

“Can we get this approved?”

We should also ask:

“What happens if the old house doesn’t sell as quickly as expected?”

A good financing strategy should account for a reasonable Plan B.

HELOC Interest Rates Are Usually Variable

Another important consideration is that many HELOCs have variable interest rates.

That means the interest rate—and potentially your required payment—can change over time.

HELOC rates are commonly tied to an index plus a lender-determined margin.

If the underlying index changes, the rate charged on the HELOC can change as well.

For someone using the HELOC as very short-term financing until the existing home sells, that may be less concerning than it would be for someone planning to carry a large HELOC balance for many years.

But you should still understand:

• The initial interest rate
• Whether the rate is variable
• How frequently it can adjust
• Any rate caps
• How the minimum payment is calculated
• Whether payments are interest-only during the draw period
• What happens when the repayment period begins
• Any annual or early-closure fees

Don’t evaluate a HELOC based solely on how much money the lender is willing to make available.

Understand the cost and repayment structure too.

What If Your Home Sells for Less Than Expected?

When homeowners estimate their available equity, they sometimes use very simple math:

Home value − mortgage balance = equity

But that isn’t necessarily the amount of cash you’ll receive when the property sells.

Suppose you estimate:

Home value: $500,000
Mortgage balance: $250,000

It looks like you have:

$250,000 of equity

Then you borrow:

$100,000 through a HELOC

Now the property has approximately:

$350,000 of total mortgage debt

If the property ultimately sells for $475,000 rather than $500,000, your gross remaining equity before selling expenses is approximately:

$125,000

And you still have to account for applicable transaction costs.

This doesn’t necessarily create a problem.

But it demonstrates why you shouldn’t build the entire strategy around the most optimistic estimate of what your current home will sell for.

A more conservative estimate can provide additional protection if the market doesn’t cooperate.

How Much Equity Should You Leave in Your Current Home?

Just because a lender allows you to borrow a certain amount doesn’t mean you necessarily should.

If you need $60,000 to complete the next purchase and qualify for a $120,000 HELOC, drawing the entire $120,000 simply because it’s available may create unnecessary debt and expense.

The better question is generally:

How much do we need to accomplish the goal while maintaining a reasonable financial cushion?

That answer will vary.

You may need funds for:

• Down payment
• Closing costs
• Prepaid expenses
• Moving costs
• Repairs
• Reserves
• Unexpected expenses during the transition

The goal isn’t necessarily to maximize the amount of equity you can extract.

It’s to structure the move efficiently.

Should You Use a HELOC for the Entire Down Payment?

You potentially can use HELOC proceeds for a significant portion of the funds needed to purchase another property, subject to the requirements of your mortgage program and lender.

But that doesn’t mean the HELOC has to fund the entire down payment.

You might combine:

• Existing savings
• HELOC proceeds
• Other eligible assets

For example, suppose you want $100,000 available for a down payment.

You already have:

$40,000 in savings

Instead of drawing the full $100,000 from your HELOC, you might determine that a:

$60,000 HELOC draw

provides the remaining funds needed.

If that results in a smaller HELOC payment, it could also help your mortgage qualification.

This is where the relationship between available assets and debt-to-income ratio becomes important.

Sometimes borrowing more allows you to make a larger down payment on the new mortgage—but simultaneously creates a larger HELOC obligation.

The numbers need to be evaluated together.

Does Using a HELOC Lower the Payment on Your New Mortgage?

Potentially.

If the HELOC proceeds allow you to make a larger down payment, the first mortgage on the new property may be smaller.

For example:

Option A — No HELOC

Purchase price: $500,000
Down payment: $50,000
New mortgage: $450,000

Option B — Additional $50,000 From HELOC

Purchase price: $500,000
Down payment: $100,000
New mortgage: $400,000

The new first mortgage is $50,000 smaller.

But Option B also created additional debt against the existing property.

So comparing the options requires looking at both payments, not just the new mortgage.

A lower new mortgage payment doesn’t automatically mean the total monthly obligation is lower.

That’s another reason an online mortgage calculator alone may not tell the full story for someone buying before selling.

Can a HELOC Help You Avoid Mortgage Insurance?

Potentially, but this requires careful analysis.

If HELOC proceeds allow you to make a larger down payment on the new property, that could affect whether mortgage insurance applies to certain Conventional financing.

For example, a homeowner might consider borrowing enough equity to reach a larger down payment.

But borrowing additional money solely to avoid mortgage insurance isn’t automatically a good financial decision.

You need to compare:

• Additional HELOC balance
• HELOC interest and payment
• New mortgage amount
• Mortgage insurance cost
• Available cash
• Expected timing of the current-home sale

Sometimes putting more down makes sense.

Sometimes keeping the HELOC smaller and accepting temporary mortgage insurance could be the better overall strategy.

The answer comes from comparing the actual numbers.

What If You Already Have a HELOC?

If you already have an open HELOC on your current home, it may make the strategy easier because you may already have access to the line of credit.

But don’t assume the full credit limit is automatically available or that drawing additional funds won’t affect the new mortgage qualification.

Before using it, determine:

• Current HELOC balance
• Available credit
• Current interest rate
• Payment after the proposed draw
• Whether the line has any restrictions
• How the new balance will be documented
• How the payment will affect your DTI

This is especially important if your original mortgage pre-approval was completed before you decided to draw from the HELOC.

Changing the HELOC balance can change the financial picture the lender originally evaluated.

Should You Open a HELOC Right Before Applying for a Mortgage?

This is where coordination matters.

Opening a new HELOC can involve a credit inquiry and creates a new credit obligation.

Drawing from it can create or increase a monthly payment.

None of those things automatically prevent you from qualifying for another mortgage.

But making those changes without discussing them with the mortgage professional handling the new purchase is unnecessary risk.

If the purpose of the HELOC is specifically to help purchase another home, the HELOC and new mortgage should ideally be planned together.

Before opening or drawing from the line, we can determine:

1. How much cash you actually need.
2. How much HELOC financing may be appropriate.
3. What the resulting payment may look like.
4. How that payment affects DTI.
5. Whether the existing mortgage must also be included.
6. Which mortgage program works best for the new property.
7. Whether another equity strategy makes more sense.

That’s considerably safer than opening a $150,000 HELOC first and figuring out the mortgage qualification afterward.

HELOC vs. Bridge Loan: Which Is Better for Buying Before Selling?

There isn’t a universal winner.

A HELOC may be attractive when:

• You have substantial equity in your current home
• You qualify for the line of credit
• You want flexibility in how much you borrow
• You don’t need to access all of your equity
• You may want the line available for other purposes
• The HELOC costs and terms make sense

A bridge loan may deserve consideration when:

• The financing need is specifically tied to moving from one home to another
• You need access to significant equity before selling
• A traditional HELOC doesn’t provide the structure or amount needed
• You expect the financing to be temporary
• The bridge-loan structure works better with the overall purchase plan

There can also be situations where neither is necessary.

Maybe you can qualify for the new mortgage without accessing the current home’s equity.

Maybe a smaller down payment works.

Maybe selling first makes more financial sense.

Maybe a contingent-upon-sale purchase is perfectly acceptable in the current market.

The best option is the one that solves the actual problem without creating unnecessary debt or cost.

A HELOC Is a Tool, Not the Strategy

This distinction matters.

A HELOC is simply one way to access home equity.

The strategy is determining how to move from your current home into the next one while balancing:

• Available equity
• Cash needed for the purchase
• Mortgage qualification
• Monthly payments
• Sale timing
• Market conditions
• Risk
• Convenience

Sometimes a HELOC is exactly the right tool.

Sometimes a bridge loan works better.

Sometimes you don’t need to borrow against the old house at all.

That’s why the first step shouldn’t necessarily be applying for a HELOC.

The first step should be determining what the entire transaction needs to look like.

How Do You Know If a HELOC Strategy Will Actually Work?

Before deciding to use a HELOC for the down payment on another home, there are really two separate questions we need to answer.

Question 1: Do you have enough accessible equity?

Question 2: Can you qualify for the new mortgage after accessing that equity?

A homeowner can have hundreds of thousands of dollars in equity and still have difficulty qualifying to buy before selling if the temporary monthly obligations become too high.

That’s why I prefer to work backward from the new purchase rather than starting with:

“How large of a HELOC can I get?”

We first determine approximately how much you want to spend on the next home, what mortgage payment you’re comfortable with, how much cash is available, and how much equity needs to be accessed.

Then we can evaluate whether a HELOC, bridge loan, smaller down payment, home-sale contingency, or another strategy makes the most sense.

Step 1: Estimate the Equity in Your Current Home

Start with a reasonable estimate of your property’s current value.

Then subtract the debts secured by the property.

For example:

Estimated home value: $550,000
First mortgage balance: $275,000
Existing HELOC balance: $0

Estimated equity:

$275,000

Again, that doesn’t mean you can necessarily borrow $275,000.

The HELOC lender will have its own maximum combined loan-to-value requirements.

And even if you could access a very large portion of the equity, you may not want to.

We’re simply establishing how much equity potentially exists.

Step 2: Determine How Much Cash You Actually Need

Next, look at the proposed purchase.

Suppose you’re buying for:

$600,000

and want to put:

$120,000 down

But you already have:

$50,000

available from savings.

Your actual funding gap may be closer to:

$70,000

plus whatever additional funds are needed for closing costs, prepaid expenses and reserves.

That’s a much different problem than assuming you need to borrow the entire $120,000 from the current house.

If a $75,000 HELOC draw accomplishes the objective, there may be no reason to borrow $125,000.

Step 3: Calculate the New Housing Payment

Next, determine the approximate payment on the home you’re purchasing.

That calculation should consider more than principal and interest.

Depending on the transaction, the complete housing expense may include:

• Principal and interest
• Property taxes
• Homeowners insurance
• Mortgage insurance, when applicable
• HOA dues, when applicable

This is particularly important for Michigan homebuyers because the property-tax amount shown for the current owner isn’t necessarily a reliable estimate of what you’ll pay after purchasing the property.

The new housing payment needs to be reasonably accurate before we can determine whether the overall strategy works.

Step 4: Account for the HELOC Payment

Now add the payment associated with the proposed HELOC draw.

Suppose accessing the $75,000 needed for the purchase creates an estimated monthly obligation of:

$600

That $600 can matter when calculating your debt-to-income ratio.

If the new mortgage qualification was already close to the allowable DTI threshold before the HELOC, adding another $600 monthly obligation could materially change the result.

This is why the amount you draw matters.

The difference between borrowing $75,000 and $125,000 isn’t simply an additional $50,000 of available cash.

It may also mean a larger monthly obligation.

Step 5: Determine How the Current Home Will Be Treated

This can be one of the biggest pieces of the entire analysis.

If you haven’t sold your existing residence yet, we need to determine how its housing expense will be treated when qualifying for the new mortgage.

The answer can depend on factors such as:

• The mortgage program
• Whether the current property is listed
• Whether it’s under contract
• The expected closing date
• Applicable underwriting requirements
• Whether the property will be sold or retained

You don’t want to discover after finding the next house that your qualification depended on excluding an existing housing payment that the lender actually has to count.

This should be addressed during the mortgage pre-approval process.

Step 6: Stress-Test the Plan

Once the numbers work from an underwriting perspective, I would take the analysis one step further.

Ask:

What if the current house doesn’t sell immediately?

Suppose you’re temporarily carrying:

Existing mortgage: $1,900

HELOC payment: $600

New housing payment: $3,600

That’s:

$6,100 per month

before considering your other debts and normal household expenses.

Maybe your income and savings make that completely manageable.

Maybe carrying $6,100 of housing obligations for several months would be uncomfortable.

Both matter.

Mortgage approval tells us whether the financing can work.

A stress test helps determine whether the strategy makes sense for you.

What Does a Complete Buy-Before-Selling Example Look Like?

Let’s put everything together.

Assume:

Current Home

Estimated value: $500,000
First mortgage balance: $225,000
Estimated equity: $275,000

New Home

Purchase price: $600,000

The homeowner wants to make a:

$120,000 down payment

They already have:

$50,000 in available cash

That leaves approximately:

$70,000

needed from another source, before accounting for the complete cash-to-close calculation.

Instead of selling the current home first, the homeowner qualifies for a HELOC and draws:

$70,000

The new home is purchased.

The homeowner then lists and sells the previous property for:

$500,000

At the sale, approximately:

$225,000 pays off the old first mortgage.

$70,000 pays off the HELOC.

That leaves approximately:

$205,000

of gross remaining equity before selling expenses and other applicable adjustments.

The homeowner could then decide what to do with the remaining proceeds.

They might:

• Keep a portion as savings or reserves
• Invest some of the proceeds
• Pay down other debt
• Apply a lump sum toward the new mortgage
• Potentially explore a mortgage recast

This is what makes home-equity planning more interesting than simply asking how much money is available.

The HELOC may be the mechanism that gets you from one transaction to the other.

It doesn’t necessarily have to be part of your long-term debt structure.

When Might a HELOC Not Be the Best Choice?

There are several situations where I would want to look closely at alternatives.

Your DTI Is Already Tight

If your mortgage qualification is already near the allowable limit, adding a HELOC payment could create a problem.

A different structure—or simply borrowing less—may work better.

You Need Nearly All of Your Available Equity

If the purchase requires extracting a very large portion of your current home’s equity, a HELOC may not provide enough access.

A bridge loan or different strategy may deserve consideration.

You Expect the Current Home to Take a Long Time to Sell

The longer you carry the HELOC and multiple housing obligations, the more important the carrying costs become.

You Don’t Actually Need the Equity

If you can purchase the next home with existing savings or a smaller down payment, borrowing against the current property may simply add unnecessary debt.

Selling First Isn’t a Major Inconvenience

Sometimes the simplest solution really is the best one.

If selling first doesn’t create a housing or timing problem, there may be little reason to create additional short-term financing.

Should You Use a HELOC or Put Less Money Down?

This is one of the comparisons I think homeowners should make before automatically borrowing against their current house.

Suppose you are purchasing for:

$500,000

You initially planned to put:

$100,000 down

But only $50,000 is currently liquid.

One option is borrowing another $50,000 through a HELOC.

Another option may be putting $50,000 down and financing a larger amount on the new mortgage.

Which is better?

We need to compare:

Option A

Smaller new mortgage + HELOC payment

versus

Option B

Larger new mortgage + no HELOC payment

The answer could depend on:

• Interest rates
• Mortgage insurance
• HELOC rate
• Expected sale date
• DTI
• Available reserves
• Long-term plans for the new mortgage

The larger down payment may look better at first glance.

But once the cost and payment of the HELOC are included, the answer isn’t always obvious.

Should You Pay Off the HELOC Immediately When the Old Home Sells?

Because the HELOC is secured by the property being sold, the outstanding balance will generally need to be satisfied as part of that sale.

That’s one reason this strategy can work well as temporary financing.

You aren’t necessarily planning to carry the HELOC for the next 10 or 20 years.

You’re using it to access equity during the period when you own both properties.

Once the existing property sells, that temporary financing can be eliminated.

That can leave you with only the mortgage on the new home.

Can You Put the Remaining Sale Proceeds Into the New Mortgage?

Yes, you may choose to make a substantial principal payment after selling the old property.

But there’s an important distinction between:

paying down the mortgage

and

lowering the required monthly payment.

Simply making a large principal payment doesn’t necessarily cause the required monthly principal-and-interest payment to be recalculated.

That’s where a mortgage recast may come into play.

If your mortgage and servicer permit recasting, you may be able to make a substantial principal reduction and then have the monthly payment recalculated based on the lower balance.

That can make the following strategy particularly useful for some move-up buyers:

Buy first → Sell old home → Pay off HELOC → Apply remaining equity to new mortgage → Recast

It can allow you to purchase before selling without necessarily maintaining the larger new-mortgage payment indefinitely.

Frequently Asked Questions About Using a HELOC for a Down Payment

Can I use a HELOC for the down payment on another house?

In many situations, yes. Funds borrowed against the equity in your current home may potentially be used toward the down payment on another property, subject to the requirements of the new mortgage and HELOC lender.

Does a HELOC count against my DTI?

The applicable HELOC payment can affect your debt-to-income ratio when qualifying for another mortgage. That’s why the HELOC should be evaluated as part of the new mortgage qualification before you borrow the funds.

Can I use a HELOC for closing costs too?

HELOC proceeds may potentially provide funds for eligible closing costs in addition to the down payment, provided the source of funds and transaction satisfy applicable mortgage requirements.

Can I use a HELOC to buy a house before mine sells?

Potentially. That’s one of the reasons homeowners consider HELOCs. Accessing equity before selling may provide the funds necessary to complete the next purchase without waiting for the existing home’s sale proceeds.

Is a HELOC better than a bridge loan?

Not necessarily. A HELOC may offer greater flexibility, while a bridge loan is generally designed specifically around short-term financing between two real estate transactions. The better choice depends on available equity, qualification, costs and timing.

Do I have to sell my current house after using the HELOC?

Not simply because you opened a HELOC. However, if your mortgage strategy and qualification were structured around selling the existing residence, changing that plan could affect the overall financial picture. Discuss any major change with your mortgage professional.

Can I use a HELOC and still get a Conventional mortgage?

Potentially, yes. The HELOC itself doesn’t automatically prevent you from obtaining a Conventional mortgage. The lender will evaluate the applicable HELOC obligation along with your other debts, qualifying income, assets and the rest of the mortgage application.

Should I get the HELOC before getting pre-approved?

I would generally evaluate the mortgage pre-approval first—or at least coordinate the two simultaneously if the HELOC is specifically intended to fund the next purchase.

That way, we can determine how much equity you actually need and what effect the HELOC may have on qualification before you create the new debt.

The Bottom Line

Yes, a HELOC can potentially be used for the down payment on another home.

For homeowners with substantial equity, it can be an effective way to access money that would otherwise remain tied up until the current property sells.

But accessing the equity is only half of the equation.

You also need to determine whether you can qualify while accounting for the:

• Existing mortgage
• HELOC payment
• New mortgage
• Other monthly debts
• Required cash to close

And you need to consider what happens if your current property takes longer to sell than expected.

That’s why a HELOC should be viewed as one potential piece of a larger buy-before-selling strategy, rather than automatically being the first solution.

Depending on your circumstances, a HELOC, bridge loan, smaller down payment, home-sale contingency, or selling first could each make sense.

The objective is to determine which approach allows you to purchase the next home while keeping the financing manageable and the transaction as flexible as possible.

Thinking About Buying Before You Sell?

If you’re a Michigan homeowner with equity and you’re considering purchasing your next home before selling your current one, BrightSide Lending can help you compare the available options.

We can review your current mortgage, estimated equity, income, debts, proposed purchase and available assets to determine whether a HELOC, bridge financing, or another strategy may make sense.

Most importantly, we can evaluate the entire transaction before you start moving money or taking on new debt.

That way, you know not only where the down payment is coming from, but whether the complete mortgage strategy works before you make an offer.
