Second home mortgages typically require 10 to 25 percent down, depending on the lender and loan type

A second home down payment is almost always larger than what you'd put down on a primary residence. Most lenders require a minimum of 10 percent, but many won't go below 15 or 20 percent. Some jumbo loan programs (for properties over $766,550 in most areas) push the requirement to 25 or 30 percent. The exact amount depends on your credit score, debt-to-income ratio, the property location, and whether you're buying in a resort area or a year-round community.

Lenders treat second homes as higher risk than primary residences because you're less likely to fight to keep a property you don't live in if money gets tight. That risk premium shows up in the down payment requirement. Cash reserves also matter more—lenders often want to see that you can cover six to twelve months of mortgage payments on both your primary home and the second home combined.

Key Takeaways

  • Second home down payments start at 10 percent but commonly run 15 to 25 percent depending on loan type and your financial profile.
  • Jumbo loans for high-value properties typically require 25 to 30 percent down, and some lenders require even more.
  • Your debt-to-income ratio on both properties combined is calculated together, which can push your down payment requirement higher than you'd expect.
  • Lenders verify liquid reserves (savings, investments) separate from the down payment itself, often requiring six to twelve months of combined mortgage payments.
  • Vacation rental properties and properties in resort areas often carry steeper down payment requirements than year-round residential second homes.

How lender type affects your down payment

Conventional loans (not backed by the Federal Housing Administration or Department of Veterans Affairs) are the most common path for second homes. Fannie Mae and Freddie Mac, the two government-sponsored enterprises that buy most conventional mortgages, allow down payments as low as 10 percent on second homes, but only if your credit score is 740 or higher and your debt-to-income ratio stays below 36 percent. If either number is weaker, expect to put down 15 or 20 percent instead.

Jumbo loans, which exceed the conforming loan limit (currently $766,550 in most U.S. counties, higher in some high-cost areas), almost never accept 10 percent down. Portfolio lenders—banks that keep loans on their own books rather than selling them—set their own rules and often require 20 to 30 percent down on second homes. Private lenders and portfolio programs are more flexible on credit and income but charge higher interest rates to offset the risk.

FHA loans are rarely used for second homes because FHA insurance is designed for owner-occupied primary residences. VA loans are also off the table unless you're using them for a primary residence and already own the second home outright. If you're financing a second home, conventional or jumbo loans are your realistic options.

What your debt-to-income ratio means for down payment size

Your debt-to-income ratio (DTI) is the total of all your monthly debt payments divided by your gross monthly income. When you apply for a second home mortgage, lenders add the new mortgage payment to your existing debts—including your primary home mortgage, car loans, student loans, credit cards, and any other obligations. This combined DTI is what determines whether you can borrow at all, and it directly affects how much down payment the lender will require.

If your combined DTI lands between 36 and 43 percent, most conventional lenders will ask for 15 to 20 percent down instead of 10 percent. If it climbs above 43 percent, you may need 25 percent down or face rejection entirely. Some lenders cap DTI at 36 percent for second homes, meaning you have no room to borrow unless you put down enough to lower the monthly payment significantly.

The math works like this: a $400,000 second home with 10 percent down ($40,000) and a 7 percent interest rate costs roughly $2,510 per month in principal and interest alone. Add property taxes, insurance, and HOA fees, and you're looking at $3,500 to $4,000 monthly. If your existing debts plus this new payment push your DTI over the lender's limit, you'll need to put down more money to reduce the monthly payment.

Cash reserves and proof of financial stability

Beyond the down payment itself, lenders require documented liquid reserves—money in savings, money market accounts, or investment accounts that you can access quickly. For a second home, most lenders want to see reserves equal to six to twelve months of combined mortgage payments on both your primary home and the second home. Some portfolio lenders require even more.

If you're putting down 20 percent on a $400,000 second home, you're writing a check for $80,000. But the lender will also want to see that you have another $40,000 to $80,000 sitting in liquid accounts after closing. This isn't borrowed money—it's cash you own outright. Retirement accounts (401k, IRA) typically don't count unless you're willing to take a withdrawal and accept the tax consequences.

Lenders verify reserves by reviewing bank statements, brokerage statements, and sometimes letters from financial institutions. They want to see that the money has been there for at least two months, not that you borrowed it from a relative the week before closing. If your reserves fall short, you'll either need to put down more cash upfront or find a lender with lower reserve requirements.

Resort and vacation rental properties cost more to finance

If your second home is in a resort area, a ski town, a beach community, or anywhere marketed primarily as a vacation destination, expect down payment requirements to jump to 20 to 30 percent. Lenders see these properties as speculative or seasonal, with higher vacancy risk and less stable value. The same applies if you plan to rent the property out as a vacation rental through Airbnb or VRBO.

Investment properties and vacation rentals are treated differently from owner-occupied second homes. If you're financing a property you'll use personally for at least part of the year, you may may have access to for owner-occupied rates and down payment requirements. But if the lender suspects you'll rent it out full-time, they'll classify it as an investment property, which typically requires 20 to 25 percent down at minimum.

Some lenders won't finance vacation rentals at all, or will only do so through specialized investment property programs with stricter terms. If you're considering renting out your second home, disclose that plan upfront so the lender can quote you the correct down payment requirement. Hiding rental intent and then renting the property after closing can trigger loan acceleration (the lender demands full repayment immediately).

How credit score affects down payment requirements

Your credit score determines not just whether you're approved, but how much cash you need to bring. A score of 740 or higher typically qualifies you for the lowest down payment the lender offers—often 10 to 15 percent on conventional loans. A score between 700 and 739 usually means 15 to 20 percent down. Below 700, you're looking at 20 to 25 percent or possible rejection.

Credit score matters because it predicts whether you'll default. Lenders see a second home as discretionary—if money gets tight, you'll stop paying the second home mortgage before you stop paying your primary home mortgage. A lower credit score signals you've already missed payments or carried high debt in the past, so the lender wants more of your own money at risk to discourage default.

If your score is below 700, you have options: wait three to six months while you pay down credit card balances and dispute any errors on your credit report, or look for portfolio lenders and private programs that accept lower scores in exchange for higher down payments and interest rates. The cost of waiting is usually lower than the cost of borrowing at a higher rate.

Down payment assistance and second homes

Down payment assistance programs—grants, forgivable loans, and matched savings accounts—are designed for first-time homebuyers purchasing a primary residence. They do not cover second homes. If you're looking to reduce the cash you need to bring, your options are limited to negotiating seller concessions (asking the seller to pay some of your closing costs) or taking out a home equity line of credit against your primary home to fund part of the down payment.

A home equity line of credit (HELOC) lets you borrow against the equity you've built in your primary home. The interest rate is usually lower than a second mortgage, and the interest may be tax-deductible if you use the funds to buy, build, or improve the second home. However, this strategy increases your total debt and your DTI, which can actually disqualify you from the second home mortgage or force a larger down payment. Run the numbers with a lender before pursuing this route.

Frequently Asked Questions

Can I put down less than 10 percent on a second home?

Rarely. Most conventional lenders cap second home loans at 90 percent loan-to-value (10 percent down). Some portfolio lenders and private mortgage companies go lower, but they charge significantly higher interest rates and require strong credit and reserves. For most borrowers, 10 percent is the practical floor.

Does my primary home mortgage payment count toward my debt-to-income ratio for the second home?

Yes. Lenders add your primary home payment, property taxes, insurance, and HOA fees to your new second home payment, plus all other debts, then divide by your gross income. This combined DTI is what determines approval and down payment size. A high primary mortgage can force you to put down more on the second home.

What if I own my primary home outright with no mortgage?

You'll have a much easier time. Without a primary mortgage payment, your DTI is lower, which means you can borrow more and may may have access to for a lower down payment on the second home. However, lenders will still require liquid reserves and will still treat the second home as higher risk than a primary residence.

Can I use a gift from family to cover the down payment?

Yes, but with conditions. Most lenders allow gift funds for down payments and closing costs, but they require a signed gift letter stating the money is a gift, not a loan. The gift giver cannot expect repayment. You'll also need to document where the gift came from—bank statements showing the transfer. Lenders verify gifts to prevent you from taking out a hidden loan that would increase your DTI.

Do I need a larger down payment if I'm buying a second home in a different state?

Not automatically, but property location does matter. Lenders assess risk based on the local real estate market, property type, and whether the area is stable or declining. A second home in a strong market may have the same down payment requirement as your primary home's market. A second home in a declining area or resort town will likely require more down. Ask the lender for the specific requirement for your property's location.
