You can get a mortgage on a second home, but qualifying takes more cash and a stronger financial profile than buying a primary residence. Plan on at least 10% down, an interest rate roughly 0.25 to 0.50 percentage points above what your main home would carry, and a property that meets a specific definition. Miss that definition and the lender reclassifies the loan as an investment property, with steeper rates and a larger down payment.
What Lenders Count as a Second Home
The label matters. It determines your rate, your down payment, and how the IRS treats your interest. To qualify for second-home financing, the property generally has to check every one of these boxes:
- A one-unit dwelling suitable for year-round occupancy. Duplexes and other multi-unit buildings don’t qualify.
- Personal use for at least part of the year. It can’t sit vacant as a pure rental.
- Your exclusive control. A property in a mandatory rental pool, a timeshare arrangement, or under a management company that dictates when you can visit won’t qualify.
- Distance from your primary residence. Most lenders want the property in a resort or vacation area, or at least 50 miles away from your main home.
That distance rule catches people off guard. A condo across town that you plan to rent on weekends is not a second home to a lender, no matter what you call it. The classification exists because you actually use the place.
What You Need to Qualify
Down Payment
Fannie Mae caps the loan-to-value ratio at 90% for a second home, so 10% down is the floor.1Fannie Mae. Eligibility Matrix Many lenders and programs push that higher, and 20% is common if you want to skip private mortgage insurance or land a better rate. On a primary residence, conventional loans can go as low as 3% down, so the jump is significant.
Credit Score
The conventional-loan floor is a 620 FICO.2Fannie Mae. General Requirements for Credit Scores For a second home, most lenders add their own overlays and want 680 or higher, and the best rates sit above 720. A score in the mid-600s will cost you real money over 30 years.
Debt-to-Income Ratio
Your total DTI, counting your primary mortgage, the proposed second-home payment, and every other recurring debt, generally has to stay at or below 43%. Some lenders will stretch that with strong compensating factors like large reserves or a high credit score, but 43% is the standard ceiling on conforming loans.
Cash Reserves
Fannie Mae requires at least two months of the new mortgage payment sitting in liquid accounts, covering principal, interest, taxes, and insurance.3Fannie Mae. Minimum Reserve Requirements Lenders often want more, particularly if you already carry other financed properties. Reserves prove you can absorb a bad month without missing payments on either home.
Loan Size Limits
For 2026, the baseline conforming loan limit is $832,750 for a one-unit property, rising to $1,249,125 in designated high-cost areas.4FHFA. FHFA Announces Conforming Loan Limit Values for 2026 Above those numbers, you’re in jumbo territory, with its own underwriting standards and often a larger down payment.
How the Rate Compares
Second-home rates run about 0.25% to 0.50% higher than primary rates. On a $500,000 loan, a quarter point is roughly $75 a month and tens of thousands over 30 years. Lenders price in the risk that if money gets tight, you’ll protect your primary home first.
Investment property loans sit higher again, often 0.50% to 0.75% above primary rates, with down payments starting at 15% for a single unit and reaching 25% on multi-unit buildings. That gap is what tempts some buyers to call an investment property a second home. The consequences of doing so are covered below.
Tax Treatment
Mortgage Interest
Interest on a second-home mortgage is deductible if you itemize. The combined mortgage debt on your primary and second home can’t exceed $750,000 for loans taken out after December 15, 2017, or $1 million for older mortgages.5Internal Revenue Service. Real Estate Taxes, Mortgage Interest, Points, Other Property Expenses The second home has to be a house, condo, or similar dwelling, but it can be in any state.
Property Taxes
Property taxes on the second home fall under the state and local tax (SALT) deduction. Starting in the 2025 tax year, the SALT cap rose from $10,000 to $40,000, with annual adjustments through 2029, and it phases down for taxpayers with modified adjusted gross income above $500,000. Property taxes on both homes plus state income taxes all share that one cap, so a second-home tax bill only helps if your primary home hasn’t already exhausted it.
The 14-Day Rental Rule
Rent the property for fewer than 15 days a year and you owe no tax on that income and don’t report it.6Internal Revenue Service. Topic No. 415, Renting Residential and Vacation Property Cross 15 days and every dollar of rental income becomes reportable, though you can then deduct a proportional share of expenses. For owners who rent during one peak week, the rule is genuinely useful.
Insurance the Lender Will Require
You’ll need a homeowners policy in place before closing, with the same core coverages as on a primary home: dwelling, personal property, and liability. A few things come up more often with vacation properties.
Flood insurance is a separate policy, and many second homes near coasts, rivers, and lakes fall inside FEMA-designated flood zones. Check this early because the premium can meaningfully change your monthly cost. Pools, docks, and hot tubs often push liability limits higher or call for an umbrella policy. And if you plan to rent the home even occasionally, a standard homeowners policy usually won’t cover incidents involving renters. You may need a landlord endorsement or a separate rental dwelling policy for those weeks.
Documentation and the Application
The paperwork looks like a primary purchase, with the added burden of showing you can carry two housing payments at once. Expect to gather:
- Two years of W-2s, or 1099s and profit-and-loss records if you’re self-employed.
- At least the most recent federal tax return, and often two years. Fannie Mae requires the most recent return filed, and lenders may ask for more depending on your income type.7Fannie Mae. B1-1-03, Allowable Age of Credit Documents and Federal Income Tax Returns
- The last 60 days of statements across checking, savings, and investment accounts, showing the source of your down payment and verifying reserves.
- Current mortgage details for your primary home: monthly payment, remaining balance, lender.
Everything feeds into the Uniform Residential Loan Application, Fannie Mae Form 1003.8Fannie Mae. Uniform Residential Loan Application (Form 1003) Section 4 is where you designate the property’s intended occupancy as “Second Home.”9Fannie Mae. Uniform Residential Loan Application That checkbox carries real weight, and misusing it is the subject of the last section.
Closing
Underwriting cross-checks your file against your credit report, employment records, and a title search, and the lender orders an appraisal through an appraisal management company to confirm the value.10Consumer Financial Protection Bureau. 12 CFR 1002.14 Rules on Providing Appraisals and Other Valuations
You must receive your Closing Disclosure at least three business days before the closing date.11Consumer Financial Protection Bureau. What Should I Do if I Do Not Get a Closing Disclosure Three Days Before My Mortgage Closing? Read it carefully. It shows the final rate, monthly payment, closing costs, and cash to close. If any number doesn’t match what you expected, raise it before signing day, not at the table.
Do Not Misrepresent Occupancy
Calling a property a second home when you actually plan to rent it full-time saves money on the front end through a lower rate and a smaller down payment. Lenders know the pattern and look for it, using occupancy audits, tax return reviews, and even utility usage checks after closing.
If a lender finds the misrepresentation, the mortgage’s acceleration clause lets it demand the entire remaining balance immediately. If you can’t pay it off, foreclosure follows, even if you’ve never missed a payment. Federally, making false statements on a mortgage application is a crime under 18 U.S.C. ยง 1014, with penalties of up to $1,000,000 in fines, up to 30 years in prison, or both.12Office of the Law Revision Counsel. 18 U.S. Code 1014 – Loan and Credit Applications Generally Loan acceleration and forced refinancing at investment-property rates are the common civil outcomes. The savings from a second-home rate are never worth losing the property.
