Yes, you can buy a second house if you can meet lending standards that are meaningfully stricter than the ones you faced on your first mortgage. Plan on at least 10 percent down, a credit score of 620 or higher (with competitive pricing really starting around 680), enough income to carry both housing payments without stretching your debt-to-income ratio past the limit, and a cash cushion left over after closing. Lenders set the bar higher because a borrower in trouble will protect the primary residence first and let the second home go.
Second Home or Investment Property
Before anything else, know which category your purchase falls into. Lenders and the IRS treat a “second home” and an “investment property” differently, and the label changes your rate, your down payment, and sometimes whether the loan gets approved at all.
Under Fannie Mae’s guidelines, a second home must be a one-unit dwelling suitable for year-round use, occupied by you for part of the year, and free of any management agreement that hands a rental company control over who stays there.1Fannie Mae. Fannie Mae Selling Guide – Occupancy Types You keep exclusive control over the property.
Rental income is where buyers get tripped up. A property with some rental activity can still qualify as a second home, but only if you don’t use that rental income to help you qualify for the loan.1Fannie Mae. Fannie Mae Selling Guide – Occupancy Types The moment you lean on projected rent to meet the debt-to-income threshold, the loan gets re-classed as an investment property, which carries down payments of 15 to 25 percent, higher rates, and larger reserve requirements.
Note that FHA and VA loans aren’t an option here. Both programs restrict their lower-down-payment benefits to primary residences, so the 3.5 percent FHA path doesn’t apply.2Fannie Mae. Fannie Mae Eligibility Matrix
Credit Score and Debt-to-Income
Fannie Mae’s floor is a credit score of 620 for a fixed-rate conventional loan and 640 for an adjustable-rate loan, whether the property is a primary residence or a second home.3Fannie Mae. Fannie Mae Selling Guide – General Requirements for Credit Scores That number alone understates what you’ll actually pay. Fannie Mae charges loan-level price adjustments on second-home loans running from 1.125 percent of the loan amount at low loan-to-value ratios up to 4.125 percent when you borrow more than 75 percent of the home’s value.4Fannie Mae. Fannie Mae LLPA Matrix A lower credit score stacks even more cost on top. Most lenders want to see 680 or better before they’ll quote competitive terms.
Debt-to-income ratio is the other hinge. Loans run through Fannie Mae’s Desktop Underwriter system cap the ratio at 50 percent. Manually underwritten loans sit at a 36 percent baseline, with room up to 45 percent for borrowers with strong credit and sufficient reserves.5Fannie Mae. Fannie Mae Selling Guide – Debt-to-Income Ratios Remember that the lender will stack the proposed second-home payment on top of your current mortgage, car loans, student loans, and minimum credit card payments. Two housing payments consume that ratio quickly.
Income stability matters as much as income amount. Lenders look for at least two years of consistent employment or self-employment in the same field.6Freddie Mac. Qualifying for a Mortgage When You’re Self-Employed Bonus, commission, and overtime pay get extra scrutiny because the underwriter has to confirm those earnings are likely to continue rather than one-time windfalls.7Fannie Mae. Fannie Mae Selling Guide – Income and Employment Documentation for DU The federal Ability-to-Repay standard separately requires lenders to make a good-faith determination, based on documented income, that you can carry the payments.8Consumer Financial Protection Bureau. Summary of the Ability-to-Repay and Qualified Mortgage Rule
Down Payment, PMI, and Reserves
The minimum down payment on a second home under Fannie Mae guidelines is 10 percent, based on a maximum 90 percent loan-to-value ratio for a one-unit property.2Fannie Mae. Fannie Mae Eligibility Matrix Put down less than 20 percent and you’ll pay private mortgage insurance, typically between 0.2 and 2 percent of the loan amount per year.9Fannie Mae. What to Know About Private Mortgage Insurance On a $400,000 loan, that is $67 to $667 added to your monthly payment. PMI falls off once you reach 20 percent equity, but it drags on cash flow until then. Many buyers find that stretching to 20 percent down saves more over time than preserving the liquidity.
You also need cash left over after closing. Fannie Mae’s Desktop Underwriter requires two months of total housing payments (principal, interest, taxes, and insurance) in reserves for a second-home transaction.10Fannie Mae. Fannie Mae Selling Guide – Minimum Reserve Requirements If you own additional financed properties beyond your primary residence and the new second home, reserve requirements climb. Checking, savings, and a portion of retirement account balances all count. The lender will trace these funds through several months of bank statements to make sure the money has actually been in your account.11Consumer Financial Protection Bureau. Submit Documents and Answer Requests From the Lender
Gift funds toward the down payment are allowed. The lender will require a signed gift letter and proof the donor had the money to give.12Fannie Mae. Fannie Mae Selling Guide – Personal Gifts Fannie Mae recognizes gifts from more than just immediate family, including domestic partners and people with long-standing familial-type relationships.
Interest Rates and Loan Limits
Second-home mortgage rates usually run 0.5 to 0.75 percentage points higher than primary residence rates. The LLPA surcharges are part of why. A buyer borrowing 60 percent of the home’s value pays 1.125 percent in LLPAs, while someone borrowing 85 percent pays 4.125 percent.4Fannie Mae. Fannie Mae LLPA Matrix Those costs either come out of pocket at closing or get baked into a higher rate. A larger down payment reduces this charge directly.
For 2026, the baseline conforming loan limit on a single-unit property is $832,750 in most of the country, and $1,249,125 in designated high-cost areas.13Federal Housing Finance Agency. FHFA Announces Conforming Loan Limit Values for 2026 Borrowing above those caps puts you in jumbo loan territory, which brings its own underwriting standards and often a larger down payment requirement.
What You’ll Need to Document
The paperwork mirrors what you provided for your first mortgage, but the review is closer because the lender is sizing you up for two properties at once. Expect to produce:
- Income proof: W-2s from the last two years and pay stubs from the most recent two months. Self-employed borrowers submit full federal tax returns (Form 1040 with all schedules) for at least two years; some lenders accept one year if you’ve been self-employed for five or more.14Fannie Mae. Documents You Need to Apply for a Mortgage7Fannie Mae. Fannie Mae Selling Guide – Income and Employment Documentation for DU
- Asset statements: two to three months of bank, investment, and retirement account statements. Any large deposit needs a documented source.
- Existing property details: market value, outstanding mortgage balance, monthly payment, and insurance costs for every property you own, plus current lease agreements if any of them generate rental income.
Accuracy on the application isn’t optional. Misstating your intent to occupy the property, inflating income, or hiding debts is mortgage fraud and carries federal criminal penalties.15Federal Housing Finance Agency. FHFA Fraud Prevention Occupancy misrepresentation (claiming the home will be a primary residence to get a better rate when you really plan to use it as a second home or rental) is a well-known pattern that lenders actively look for.
If you already have rental properties, the lender counts only 75 percent of gross rental income toward your qualifying income. The 25 percent reduction covers expected vacancies and maintenance.16Fannie Mae. Fannie Mae Selling Guide – Rental Income Current leases or comparable market rent data back up the numbers. Short-term rental income gets heavier scrutiny: lenders generally want two years of consistent booking history and matching Schedule E filings before they’ll count it.
Tax Treatment of a Second Home
How you use the property drives how it’s taxed, and the differences can run into thousands of dollars a year.
Mortgage Interest
You can deduct mortgage interest on a second home the same way you deduct it on your primary residence, provided you itemize. For mortgages taken out after December 15, 2017, the combined acquisition debt on both homes cannot exceed $750,000 ($375,000 if married filing separately). Mortgages originated on or before that date fall under the older $1 million limit.17Internal Revenue Service. Real Estate Taxes, Mortgage Interest, Points, Other Property Expenses If you rent the home out part of the year, you have to use it personally for more than 14 days or more than 10 percent of the rental days (whichever is longer) for it to still count as a second home for this deduction.18Internal Revenue Service. IRS Publication 936 – Home Mortgage Interest Deduction
Property Taxes and the SALT Cap
Property taxes on a second home are deductible, but they fall under the same state and local tax cap that limits your combined deduction for state income taxes, local taxes, and property taxes on your federal return. If your primary home’s property taxes and your state income tax already max out that cap, the property taxes on the second home provide no additional federal benefit. This is a common miscalculation when buyers tally the true carrying cost.
The 14-Day Rental Rule
Rent your second home for fewer than 15 days in a year and you don’t have to report that rental income to the IRS at all.19Internal Revenue Service. IRS Publication 527 – Residential Rental Property Cross that threshold and all the rental income becomes reportable, with deductions split between personal and rental use on Schedule E.
Capital Gains at Sale
The $250,000 capital gains exclusion ($500,000 for joint filers) that shelters profit on a home sale applies only to a primary residence. On a second home that has appreciated, you’ll owe capital gains tax on the full profit.20Internal Revenue Service. IRS Topic 701 – Sale of Your Home Some owners later convert the property to a primary residence and live in it for at least two of the five years before selling to qualify for the exclusion, but the IRS applies additional rules to homes that weren’t always a primary residence.
Insurance, Taxes, and Ongoing Costs
Insurance on a second home almost always costs more than comparable coverage on a primary residence. The home sits unoccupied for stretches, raising the risk of undetected damage from burst pipes, theft, or vandalism. Location drives much of the premium: a beach house in a hurricane zone or a mountain cabin in wildfire country carries higher base rates and often elevated deductibles for wind or fire. Pools and hot tubs add liability exposure and push premiums higher.
If you plan to rent the home even occasionally, standard homeowners coverage may not be enough. Rental activity introduces commercial-level liability, and the insurer may require an endorsement or a separate landlord policy.
Then layer in property taxes without the benefit of any homestead exemption your state offers for primary residences, HOA dues, maintenance on a property you can’t check on daily, and possibly a management company. Those ongoing costs can easily add 2 to 4 percent of the home’s value per year on top of your mortgage payment.
Local Rental Rules to Check First
If any part of your plan involves renting the property when you aren’t there, verify local short-term rental laws before making an offer. A growing number of cities and counties restrict or ban short-term rentals, require special licensing, cap the number of rental days per year, or prohibit non-owner-occupied rentals outright. HOA covenants add another layer, and many prohibit rentals shorter than 30 days. Buying with a rental strategy and then learning the strategy is illegal where the home sits is an expensive and increasingly common mistake. Pull the zoning code, read the HOA governing documents, and confirm licensing requirements with the municipality before you close.
