Buying a Second Home: What to Know Before You Start

Whether you’re dreaming of a vacation getaway, a place closer to family or a property that could one day become your primary residence — buying a second home is an exciting next step. There are a variety of reasons to buy another home, including a location preference: you want a place near your office or where you travel frequently even if you don’t live there full-time, or you’re interested in establishing residency someplace for your future retirement.

The process of buying a second home is similar to buying your first home, but the requirements are stricter. Understanding how the nuances of a second home purchase are different from buying a primary residence will empower you with the knowledge you need when you’re ready to shop for that additional property.

Keep in mind that lender requirements for second homes can vary, and the guidelines here reflect general standards. Your specific situation — including your lender, loan type and financial profile — may differ. This article is meant as a general guide; always consult with your lender and a qualified financial professional before making any purchase decisions.

What Counts as a Second Home?

A second home is any residential property you own in addition to your primary residence and plan to live in for at least part of the year. It doesn’t matter if this is for vacation, seasonal use, a pre-retirement purchase, or a place close to your family — the key element for lenders is that the second home is for your personal use, not primarily as a business for rental income.

Fannie Mae and Freddie Mac, which provide guidelines for lenders who want to sell their loans to these two quasi-government entities, require that a second home be a single-unit dwelling that can be used for year-round occupancy. The home must be primarily for your personal use. While you can rent it out when you’re not using it, there are limits to how much time it can be rented to qualify as a second home. Note that rental income from a second home generally cannot be used to help you qualify for the mortgage — lenders generally want to see that you can carry both payments on your own income and assets.

Second Home vs. Investment Property: What’s the Difference?

While many people use the term second home interchangeably to refer to both an investment property and a vacation home, the distinction between the two has important implications for your mortgage rate, down payment requirements, homeowner’s insurance and taxes.

Second Home Qualifications

If you plan to live in a house for at least part of the year, that is considered a second home. Most lenders let you rent the property for up to 180 days per year and still qualify as a second home. That might mean you can qualify for a lower mortgage rate and lower down payment than an investment property.

Investment Property

If you buy a property primarily to generate rental income, which is considered a higher risk by lenders, typically you need a larger down payment and will face stricter requirements as well as higher rates. Even if you call your property a second home, if you intend to rent it out full-time, lenders will classify it as an investment property.

Second Home Mortgage Requirements

Just as second homes and investment properties are treated differently by lenders, mortgage providers apply stricter standards for second homes compared to primary residences. Generally, this is because second homes are considered riskier investments. In theory, if a borrower runs into financial trouble, they’re more likely to keep up with payments on their main residence than on a vacation home.

Down Payment for a Second Home

While some loan programs allow buyers of primary residences to make a down payment as low as 3%, those programs are not available for second homes. Depending on the lender and individual, a down payment of 10% to 20% will be required for a second home. Putting down 20% or more can also help you avoid private mortgage insurance (PMI) and may earn you a more favorable interest rate.

In addition, the down payment for a second home must come from your personal finances. Typically, gift funds are not allowed, and down payment assistance programs are generally limited to primary residences.

Credit Scores & Second Homes

The stronger your credit score, the better interest rate you’ll be offered on your second home mortgage. Reviewing your credit score before you apply can make a difference in your borrowing costs.

Lenders typically require a minimum credit score of 680 or above for a second home. If your credit score is 720 or higher, you’re likely to get lower interest rates. If you own more than six properties with a mortgage on each, lenders will likely require a credit score of 720 or higher.

Debt-to-Income Ratio

Your debt-to-income (DTI) ratio compares the minimum payment on all monthly debts to your gross monthly income. Most lenders cap your maximum DTI ratio between 43% and 45% when you apply for a second mortgage. In other words, if your gross monthly income is $15,000, your total minimum debt payments on your first mortgage, second mortgage and other recurring debt payments such as a car loan, student loan or credit card should be less than $6,450 to $6,750. Both your existing mortgage and your new second home payment count toward your DTI ratio. Lenders also look at your loan-to-value (LTV) ratio — the amount you’re borrowing compared to the home’s appraised value — which can affect both your rate and your approval odds.

How Much Cash Do You Need to Have for a Second Home?

Since lenders consider buying a second home as riskier than buying a primary residence, they typically want to see evidence of financial stability before approving a loan. Lenders generally prefer that borrowers have two to six months of mortgage payments — covering the combined payments for both your primary and secondary residence — in liquid reserves. If you have a borderline credit score or DTI ratio, healthy reserves can help offset those issues.

What Type of Mortgage Can I Use for a Second Home?

Unless they’re paying cash, many second home buyers choose a conventional mortgage to finance their purchase. Typically, conventional loans offer the most competitive interest rates.

If you’re buying a more expensive second home with a purchase price that exceeds conventional loan limits, you may need a jumbo loan. While loan limits vary by location and are updated annually, in 2026 conventional loan limits are $832,750 in most markets, and $1,249,125 in high-cost housing markets.

FHA, VA, and USDA loans are typically reserved for primary home purchases, although there may be some exceptions.

Can I Use My Existing Home’s Equity to Buy a Second Home?

Many homeowners have significant home equity in their primary home, especially if values in their area have increased and they have paid down their mortgage balance. Your home equity can be a source of funding to make a large down payment or even pay cash for a second home depending on your amount of equity and the price of the home.

There are three ways you can borrow from your home equity for a second home. Which one works best for you depends on your overall financial plan, so it’s best to discuss these with an expert.

Borrowing options might include:

• Home equity loan: A home equity loan provides a lump sum of cash secured by your primary residence that you repay at a fixed rate. This is a second loan in addition to your primary mortgage.
• HELOC: A home equity line of credit (HELOC) provides flexible access to your home equity that you can draw from as needed, such as for a down payment on a second home. You repay only the amount you use, typically at a variable rate.
• Cash-out refinance: Cash-out refinancing replaces your existing mortgage with a new, larger loan. You take the difference as cash to use for a down payment or second home purchase.

Are Interest Rates Higher for Second Homes?

Keep in mind that interest rates are typically higher for a second home, which can make a bigger difference depending on current interest rates. It’s important to talk to your lender about the options for a conventional mortgage or jumbo loan for a second home and compare it to your options for cash-out refinancing, a home equity loan or a HELOC.

Second home loans usually have a slightly higher rate than primary home loans because lenders view them as a higher risk since borrowers will typically prioritize their primary residence payments if they run into financial trouble. In practice, this premium is typically in the range of 0.50 to 0.875 percentage points above primary residence rates, though the exact difference depends on your borrower profile.

Your mortgage rate for your second home loan will be influenced by your credit score, your debt-to-income ratio, your down payment, and your cash reserves, along with other factors.

Tax Considerations for Second Homeowners

If you’re considering buying a second home, it’s wise to talk with a tax professional and an insurance agent, since the rules about taxes and insurance vary for a second home, investment property and primary residence.

Mortgage interest on a second home may be tax-deductible if you use the property personally. However, whether you qualify depends on the total mortgage debt on your homes and current IRS limits.

If you rent your property to others, IRS rules depend on how many days you personally use the home versus how many days you rent it to others. In this scenario, you should consult a tax advisor.

You may be able to deduct the property taxes you pay on a second home, but combined state and local taxes are capped by IRS rules. That maximum includes all property taxes on every property you own.

Is Buying a Second Home Right for You?

To determine whether owning a second home is a dream you should make a reality, think about your long-term financial goals and why you want a second home. If you love a vacation destination, consider how much effort it would take to travel there and, realistically, how often you would use a home in that location.

A second home can provide an additional asset in your portfolio to sell, a stream of income or a place to create memories with your family and friends. At the same time, a second home carries costs such as maintenance, utilities, insurance and sometimes homeowner association dues.
