Yes, you can use home equity as a down payment, but the lender for your new mortgage will have specific rules about how
Home equity—the difference between what your home is worth and what you owe on it—can be converted into cash through a home equity loan or line of credit, and that cash can then be used toward a down payment on another property. Most mortgage lenders will accept this source of funds. However, the lender underwriting your new mortgage will require documentation proving where the money came from, and some lenders have restrictions on how recently you borrowed it or how much of your down payment can come from borrowed funds rather than your own savings.
The key constraint is not whether you can use home equity, but whether doing so makes financial sense for your situation. You are essentially taking on a second debt obligation to fund a first one, which changes your total monthly payments and your debt-to-income ratio—the number lenders use to decide whether to approve you and at what interest rate.
Key Takeaways
- Home equity loans and home equity lines of credit (HELOCs) both convert your home's value into usable cash for a down payment.
- Your new mortgage lender will ask for bank statements or loan documents showing where the down payment money came from, and will verify the funds are yours to use.
- Borrowing against home equity increases your total monthly debt payments, which can lower the mortgage amount you are approved for on the new home.
- Some lenders require a waiting period—often 30 to 60 days—between when you borrow home equity funds and when you close on the new mortgage, to confirm the money is genuinely yours and not a last-minute gift.
- If you default on either the home equity loan or the new mortgage, the lender holding the first lien (usually the original mortgage) has priority in foreclosure.
How home equity loans and HELOCs work as down payment sources
A home equity loan is a lump sum you borrow against your home's equity, repaid in fixed monthly installments over a set term, usually 5 to 15 years. A home equity line of credit (HELOC) works more like a credit card: you have access to a credit limit, draw what you need when you need it, and pay interest only on the amount you use. Both are secured by your home, meaning the lender can foreclose if you stop paying.
For a down payment, a home equity loan is often simpler because you receive the full amount upfront and can show your new mortgage lender a closed loan document. A HELOC requires you to draw the funds before closing on the new home, and some lenders are cautious about HELOCs because the credit line can be frozen or reduced by the HELOC lender if your credit score drops or if the housing market declines sharply.
Both options require that you have built up equity—typically at least 15 to 20 percent of your home's current value—and that your credit score and income support borrowing additional money. Interest rates on home equity products are usually lower than personal loans or credit cards because your home secures the debt, but they are typically higher than your primary mortgage rate.
What your new mortgage lender will require from you
When you explore for a mortgage on a new property, the lender will ask you to document the source of your down payment. If part or all of it comes from a home equity loan or HELOC, you will need to provide the loan documents, recent bank statements showing the funds were deposited into your account, and proof that the money has been in your account for a minimum period—often 30 to 60 days, depending on the lender's policy.
This waiting period exists because lenders want to confirm the funds are genuinely yours and not a last-minute gift or borrowed money you have not disclosed. If you borrowed the funds very recently, some lenders will treat them as a gift or a co-signer obligation rather than your own resources, which affects how they calculate your debt-to-income ratio and may change your approval status or interest rate.
You will also need to disclose the monthly payment obligation on the home equity loan or HELOC to your new mortgage lender. The lender will add this payment to your total monthly debt when calculating whether you can afford the new mortgage. This is a critical step: if your debt-to-income ratio is already high, the additional home equity payment may reduce the mortgage amount you are approved for, or disqualify you entirely.
How borrowing home equity affects your mortgage approval
Most mortgage lenders use a debt-to-income ratio to decide how much they will lend you. This ratio compares your total monthly debt payments—including the new mortgage, car loans, credit cards, student loans, and now a home equity payment—to your gross monthly income. Lenders typically want this ratio to be no higher than 43 to 50 percent, depending on the lender and your credit profile.
When you add a home equity loan payment to your existing debts, you are reducing the amount of income available to cover a new mortgage payment. For example, if you earn $5,000 per month and already have $1,500 in monthly debt payments, your available debt capacity is $650 (at a 43 percent ratio). If you then borrow $50,000 against home equity at a monthly payment of $300, your available capacity drops to $350—which may not be enough to may have access to for the mortgage you want.
Before you borrow home equity for a down payment, contact a mortgage lender and ask them to run a preliminary debt-to-income calculation with the home equity payment included. This takes 15 minutes and tells you whether the strategy will actually increase the mortgage you can obtain or whether it will reduce it.
Comparing home equity borrowing to other down payment sources
| Down Payment Source | Time to Access Funds | Lender Documentation Required | Impact on Debt-to-Income Ratio |
|---|---|---|---|
| Savings or checking account | when ready (funds already yours) | Bank statements showing 2 months of history | None |
| Home equity loan | 1 to 2 weeks (after approval) | Loan documents, bank statements, 30–60 day seasoning period | Monthly payment added to total debt |
| Home equity line of credit (HELOC) | 1 to 2 weeks (after approval) | HELOC documents, bank statements, 30–60 day seasoning period | Monthly payment added to total debt (or credit limit if not yet drawn) |
| Gift from family member | when ready (if funds are available) | Gift letter signed by donor, bank statements showing funds came from donor's account | None (gift is not debt) |
| 401(k) loan or withdrawal | 1 to 2 weeks | Loan documents or withdrawal confirmation, tax forms | Loan payment added if borrowed; withdrawal may affect income calculation |
Risks of using home equity for a down payment
The primary risk is that you now have two mortgages or mortgage-like obligations secured by the same home. If you fall behind on either payment, you risk foreclosure. The holder of the first lien (usually your original mortgage) has priority in foreclosure, meaning they get paid first from the sale proceeds. The home equity lender is in second position and may recover nothing if the home sells for less than what you owe on both loans combined.
A second risk is that home equity interest rates and terms can change. If you used a HELOC, the lender can freeze your credit line or raise your interest rate if your credit score drops or if the housing market declines. If you used a home equity loan with a variable rate, your monthly payment could increase significantly if interest rates rise.
A third risk is that you are betting on the value of your home remaining stable or increasing. If your home's value drops, your equity shrinks, and you may owe more on both loans combined than your home is worth—a situation called being underwater. This does not when ready force you to sell, but it limits your options if you need to move or refinance.
When home equity borrowing makes sense for a down payment
Using home equity for a down payment makes the most sense when you have substantial equity (at least 20 to 30 percent of your home's value), a stable income, and a clear plan to repay both the home equity loan and the new mortgage. It also makes sense if the alternative is to pay private mortgage insurance (PMI) on the new home—PMI is required when your down payment is less than 20 percent, and it can cost 0.5 to 1.5 percent of the loan amount annually. If borrowing home equity allows you to put down 20 percent and avoid PMI, the math may work in your favor.
Home equity borrowing is less attractive if you are already stretched financially, if your income is variable or at risk, or if you are borrowing against a home you plan to sell within a few years. In those cases, the additional monthly payment and the risk of owing more than your home is worth outweigh the benefit of a larger down payment.
Frequently Asked Questions
Will my new mortgage lender care if I borrowed the down payment money?
Yes. Lenders require documentation of where down payment funds came from and typically want to see the money in your account for 30 to 60 days before closing. They will also add any new monthly debt payments to your debt-to-income ratio, which may reduce the mortgage amount you are approved for. Transparency is essential—do not hide the home equity loan from your lender.
Can I use a HELOC instead of a home equity loan for a down payment?
Yes, but some lenders are more cautious about HELOCs because the credit line can be frozen or reduced if your credit score drops. You will need to draw the funds before closing and show them in your bank account for the required seasoning period. Ask your mortgage lender upfront whether they have any restrictions on HELOC-funded down payments.
What happens if I cannot pay both the home equity loan and the new mortgage?
If you default on either loan, the lender holding the first lien (usually your original mortgage) can foreclose and sell your home. The second lien holder (the home equity lender) gets paid only if there is money left after the first lien is satisfied. You could lose your home and still owe money to the second lender.
Is it better to use home equity or to pay PMI on a smaller down payment?
It depends on the numbers. PMI typically costs 0.5 to 1.5 percent of the loan amount annually and can be removed once you reach 20 percent equity. A home equity loan has a fixed monthly payment and interest rate. Run both scenarios with a mortgage lender: compare the total cost of PMI over time against the monthly cost of a home equity loan, and factor in the impact on your debt-to-income ratio.
Can I borrow home equity if I am still paying off my first mortgage?
Yes. Most homeowners with equity can borrow against it while still paying a first mortgage. The home equity lender will place a second lien on your home, meaning they have second claim to the home's value if you default. Your first mortgage lender may have no objection, but check your original mortgage documents for any restrictions on second liens.
