Yes, you can use home equity as a down payment, but the money has to move through a loan first

If you own a home with equity built up, you can borrow against that equity and use the cash to put down on another property. The lender will not hand you a check labeled "down payment funds"—instead, you take out a home equity loan or home equity line of credit (HELOC), receive the money, and then use it however you choose, including as a down payment on a new purchase.

The catch is that you are now carrying two debts: the original mortgage on your first home and a new loan against that same home's equity. A mortgage lender will see both when you apply to buy the second property, and both will count against your debt-to-income ratio. This can shrink the amount you are allowed to borrow for the new purchase, or disqualify you entirely if your income is not high enough to support both payments.

The timing also matters. Most lenders want to see that the equity loan has been open for at least a few months before you apply for a mortgage on the new property. Some require six months; others may accept three. Applying for both at the same time raises red flags because lenders worry you are overextending yourself.

Key Takeaways

  • Home equity loans and HELOCs let you borrow against your home's value, but the borrowed money counts as new debt on your credit report and mortgage application.
  • A mortgage lender will factor both your original mortgage payment and your new equity loan payment into your debt-to-income ratio, which may reduce how much you can borrow for the new property.
  • Most mortgage lenders prefer to see an equity loan open for at least three to six months before you apply for a mortgage on a second property.
  • If you sell your first home before paying off the equity loan, the lender will take their payoff from the sale proceeds before you receive any cash.

How home equity loans and HELOCs work as down payment sources

A home equity loan is a lump sum you borrow against the equity in your home. You receive all the money at once, repay it over a fixed term (usually five to fifteen years) at a fixed interest rate, and make monthly payments. It works like a second mortgage.

A HELOC is a line of credit, similar to a credit card. You can draw from it as needed up to your credit limit, pay interest only on what you borrow, and the rate is usually variable (it changes with market rates). HELOCs are more flexible if you do not need all the money at once, but the variable rate means your payment can rise if interest rates climb.

Both require your home to be the collateral. If you stop paying, the lender can foreclose. Both also show up on your credit report as new accounts and new debt, which temporarily lowers your credit score and signals to other lenders that you are taking on more risk.

What happens to your debt-to-income ratio when you borrow against equity

Mortgage lenders use your debt-to-income ratio (DTI) to decide how much you can borrow. This is the total of all your monthly debt payments divided by your gross monthly income. Most lenders want your DTI to stay below 43 percent, though some go as high as 50 percent depending on your credit score and down payment size.

When you take out a home equity loan, the monthly payment gets added to your DTI calculation. If your original mortgage is $1,500 a month and your new equity loan is $400 a month, lenders now see $1,900 in housing debt before you even apply for the new mortgage. If you earn $5,000 a month gross, that is already 38 percent of your income spoken for. A new mortgage payment of $1,200 would push you to 62 percent—well over the limit.

The solution is either to earn more, pay down other debts first, or borrow less from the equity line. Some buyers wait to apply for the equity loan until after they have been pre-approved for the new mortgage, so they know exactly how much they can afford to borrow without exceeding their DTI limit.

Timing: when to open an equity loan relative to a mortgage application

If you open a home equity loan and immediately apply for a mortgage on a new property, lenders see a red flag: you just took on new debt and now you want to take on more. This pattern suggests you may be overextended or desperate, which increases their risk.

Most conventional mortgage lenders want to see the equity loan open for at least three to six months before you apply for the new mortgage. During that time, you should make all payments on time and in full. This shows the lender that you can handle the extra debt responsibly.

Some lenders are stricter. If you have a lower credit score or a smaller down payment planned, they may require six months or longer. Ask your mortgage lender about their specific timeline before you open the equity account—do not assume all lenders have the same rule.

How selling your first home affects an equity loan

If you plan to sell your first home after buying the second one, the equity loan does not simply disappear. When you close the sale, the title company will pay off the original mortgage first, then the home equity loan, then any other liens. Whatever is left goes to you.

This matters because if your home sells for less than you owe on both loans combined, you will owe the difference out of pocket. If you borrowed $50,000 against equity and your home sells for $20,000 less than your total debt, you will need to bring $20,000 to closing to pay off the shortfall.

If you plan to keep both properties long-term, this is not a concern. But if you are counting on selling the first home to pay off the equity loan, run the numbers first with a real estate agent or your lender.

Interest rates and costs of borrowing against equity

Home equity loans and HELOCs typically carry lower interest rates than personal loans or credit cards because your home is collateral. As of recent years, rates have ranged from around 7 to 12 percent depending on your credit score, the lender, and market conditions—but these rates change constantly and vary by lender.

The cost of borrowing $50,000 at 8 percent over ten years is roughly $12,000 in interest. Over fifteen years at the same rate, it is roughly $18,000. The longer you stretch the repayment, the more interest you pay, but your monthly payment drops.

Some lenders offer a promotional period on HELOCs where you pay interest-only for the first five to ten years, then switch to principal-plus-interest payments. This lowers your payment early on but raises it sharply later. Read the terms carefully and calculate what your payment will be after the promotional period ends.

Alternatives if you cannot or should not borrow against equity

If you do not have enough equity, your credit score is too low to may have access to for a home equity loan, or you do not want to risk your home as collateral, other options exist.

A personal loan does not use your home as collateral, but interest rates are higher (typically 8 to 36 percent depending on your credit) and you can borrow less (usually $1,000 to $50,000). A cash-out refinance replaces your existing mortgage with a new, larger one and gives you the difference in cash—but this resets your loan term and may raise your interest rate if rates have climbed since you bought.

You can also delay the purchase until you have saved more cash, ask a family member for a loan, or look for a property with a lower purchase price that requires a smaller down payment. Some first-time buyer programs allow down payments as low as 3 percent, which means you need less cash upfront.

Frequently Asked Questions

Will taking out a home equity loan hurt my credit score?

Yes, temporarily. Opening a new account triggers a hard inquiry, which lowers your score by a few points. Your score will also dip because your total available credit decreases (the new loan counts as used credit). The score usually recovers within a few months if you make on-time payments. However, the inquiry and new account stay on your report for up to two years.

Can I use a HELOC instead of a home equity loan for a down payment?

Yes. A HELOC works the same way—you draw the cash and use it however you want. The advantage is flexibility: you only pay interest on what you actually borrow. The disadvantage is that the interest rate is variable, so your payment can rise if rates go up. Some lenders also require you to draw the full amount upfront before you can use it, which defeats the flexibility advantage.

What if I cannot pay back the equity loan?

The lender can foreclose on your home, just as your original mortgage lender can. This is why borrowing against equity is riskier than taking out a personal loan—you are putting your primary residence at stake. If you are unsure you can afford both the equity loan payment and a new mortgage payment, do not borrow.

Do I have to tell my mortgage lender I borrowed against equity?

Yes. When you apply for a mortgage, the lender pulls your credit report, which shows all your debts and new accounts. Hiding it or lying about it is mortgage fraud. The lender will find out during underwriting, and they can deny your application or cancel it after closing if they discover you lied.

Can I borrow more than my home's equity?

No. Most lenders will let you borrow up to 80 to 85 percent of your home's total value, minus what you still owe on the original mortgage. If your home is worth $300,000 and you owe $200,000, your equity is $100,000. Most lenders will let you borrow up to $80,000 of that (80 percent of $300,000 minus $200,000 owed). Some lenders go higher, but borrowing more than your equity means you are borrowing against future appreciation, which is riskier.
