Yes, you can buy a second house if you meet lending standards that run tougher than your first mortgage. Plan on a minimum 10 percent down payment, a credit score of at least 620 (with meaningfully better pricing above 680), enough income to carry both housing payments comfortably, and cash reserves left over after closing. Lenders raise the bar on every metric because borrowers under financial pressure protect their primary home first and let a second one go.
Second Home or Investment Property
Before anything else, know which category your purchase falls into. Lenders and the IRS draw a hard line between a second home and an investment property, and the classification affects your rate, down payment, tax treatment, and whether the loan gets approved at all.
Under Fannie Mae’s guidelines, a second home must be occupied by you for part of the year, must be a single-unit dwelling suitable for year-round use, and cannot be under any management agreement that gives a rental company control over occupancy.1Fannie Mae. Fannie Mae Selling Guide – Occupancy Types You need exclusive control.
Rental income is where buyers slip. A property can still qualify as a second home if it produces some rental income, but only if that income is not used to help you qualify for the mortgage.1Fannie Mae. Fannie Mae Selling Guide – Occupancy Types The moment you list rental income on the application to meet the debt-to-income threshold, the property gets reclassified as an investment. Investment properties come with steeper down payments (typically 15 to 25 percent), higher rates, and tighter reserves.
Credit Score, Income, and Debt-to-Income
Fannie Mae’s stated minimum credit score is 620 for a fixed-rate conventional mortgage and 640 for an adjustable-rate loan, whether the home is primary or secondary.2Fannie Mae. Fannie Mae Selling Guide – General Requirements for Credit Scores The number is misleading, though, because Fannie Mae charges loan-level price adjustments on second-home mortgages that run from 1.125 percent of the loan amount at low loan-to-value ratios up to 4.125 percent when borrowing more than 75 percent of the home’s value.3Fannie Mae. Fannie Mae LLPA Matrix Lower credit stacks more cost on top. In practice most lenders want to see 680 or better before offering competitive terms.
Your debt-to-income ratio matters more than any single score. For loans run through Fannie Mae’s Desktop Underwriter, the maximum DTI is 50 percent. Manually underwritten loans cap at 36 percent, with room up to 45 percent for borrowers who bring strong credit and sufficient reserves.4Fannie Mae. Fannie Mae Selling Guide – Debt-to-Income Ratios The calculation stacks your proposed second mortgage on top of your existing one, plus car loans, student loans, and minimum credit card payments. Two housing payments consume that ratio fast.
Income stability weighs as heavily as the amount. Lenders want at least two years of consistent employment or self-employment in the same field.5Freddie Mac. Qualifying for a Mortgage When You’re Self-Employed Bonuses, commissions, and overtime get extra scrutiny because the lender has to confirm those earnings are likely to continue, not one-time windfalls.6Fannie Mae. Fannie Mae Selling Guide – Income and Employment Documentation for DU Federal Ability-to-Repay rules require lenders to make a good-faith determination that you can afford the payments based on documented income.7Consumer Financial Protection Bureau. Summary of the Ability-to-Repay and Qualified Mortgage Rule
If you already own rentals, only 75 percent of gross rental income counts toward qualifying income. The 25 percent reduction accounts for vacancies and maintenance.8Fannie Mae. Fannie Mae Selling Guide – Rental Income Short-term rental income from platforms like Airbnb gets more scrutiny still: lenders typically want two years of booking history and matching Schedule E returns before crediting any of it.
Down Payment, PMI, and Cash Reserves
The minimum down payment on a second home under Fannie Mae guidelines is 10 percent, tied to a maximum 90 percent loan-to-value ratio on a one-unit property.9Fannie Mae. Fannie Mae Eligibility Matrix Government-backed loans are off the table. FHA rules explicitly prohibit financing anything other than a primary residence, so the 3.5 percent option does not apply. VA loans carry the same primary-residence restriction.
Anything less than 20 percent down triggers private mortgage insurance. PMI protects the lender if you default and typically costs 0.2 to 2 percent of the original loan amount per year.10Fannie Mae. What to Know About Private Mortgage Insurance On a $400,000 loan, that translates to roughly $67 to $667 per month. PMI drops off once you reach 20 percent equity. Many second-home buyers find that stretching to a 20 percent down payment costs less over time than keeping the cash liquid.
Cash reserves are non-negotiable. Fannie Mae’s Desktop Underwriter requires two months of total housing payments (principal, interest, taxes, and insurance) sitting in reserve for a second-home transaction.11Fannie Mae. Fannie Mae Selling Guide – Minimum Reserve Requirements Owning additional financed properties pushes that figure higher. Checking, savings, and a portion of retirement balances all count. The lender will verify with several months of bank statements to confirm the money hasn’t just been parked from an undisclosed loan.12Consumer Financial Protection Bureau. Submit Documents and Answer Requests From the Lender
Gift funds toward the down payment are permitted, but the lender will require a signed gift letter and proof the donor had the money.13Fannie Mae. Fannie Mae Selling Guide – Personal Gifts
Interest Rates and Loan Limits
Second-home mortgage rates typically run 0.5 to 0.75 percentage points above primary-residence rates. Part of that spread comes from Fannie Mae’s loan-level price adjustments, which range from 1.125 percent to 4.125 percent of the loan amount depending on how much you borrow against the value.3Fannie Mae. Fannie Mae LLPA Matrix Those fees either get paid at closing or absorbed into a higher rate. A larger down payment substantially reduces the surcharge: borrowing 60 percent of value pays 1.125 percent in LLPAs; borrowing 85 percent pays 4.125 percent.
For 2026, the baseline conforming loan limit on a single-unit property is $832,750 across most of the country. In designated high-cost areas the ceiling rises to $1,249,125.14Federal Housing Finance Agency. FHFA Announces Conforming Loan Limit Values for 2026 Borrowing above those limits moves you into jumbo territory, with its own underwriting standards and typically an even larger down payment.
Documents You’ll Need
The paperwork resembles what you provided for your first mortgage, but underwriters look harder because they’re assessing your ability to carry two properties.
- Income proof: two years of W-2s and the most recent two months of pay stubs. Self-employed borrowers provide full federal tax returns (Form 1040 with schedules) for at least the prior two years. Some lenders will accept one year of returns from borrowers self-employed five or more years.15Fannie Mae. Documents You Need to Apply for a Mortgage6Fannie Mae. Fannie Mae Selling Guide – Income and Employment Documentation for DU
- Asset statements: two to three months of bank, investment, and retirement account statements. Large deposits require a documented paper trail.
- Existing property details: market value, mortgage balance, monthly payment, and insurance for every property you own, plus current leases if any generate rent.
The core form is the Uniform Residential Loan Application (Fannie Mae Form 1003), which captures employment history, monthly expenses, and complete real estate holdings.16Fannie Mae. Uniform Residential Loan Application – Form 1003 Accuracy is not optional. Misrepresenting your intent to occupy, inflating income, or hiding debt is mortgage fraud, which carries federal criminal penalties including prison time and restitution.17Federal Housing Finance Agency. FHFA Fraud Prevention Telling the lender you’ll occupy the property as a primary residence to secure a lower rate when you actually plan to use it as a second home or rental is one of the most commonly investigated schemes.
What the Application and Closing Look Like
Once your file is submitted, an underwriter verifies everything against guidelines and the lender orders a professional appraisal in the second home’s local market. If the appraisal comes in low, you’ll renegotiate the price, increase your down payment to cover the gap, or walk away.
Conditional approval usually brings follow-up requests: updated bank statements, explanations for recent credit inquiries, clarification on flagged items. The final step before signing is the Closing Disclosure, which lays out the exact loan terms, rate, monthly payment, and closing costs. Federal law requires you to receive that document at least three business days before closing.18Consumer Financial Protection Bureau. TILA-RESPA Integrated Disclosure FAQs Certain changes reset the clock. Use the window to check every line against your earlier Loan Estimate. Closing costs on a second home generally run 2 to 6 percent of the purchase price, covering appraisal, title insurance, attorney fees, and recording charges.
Tax Consequences of Owning a Second Home
How you use the property drives the tax treatment. Getting this right can save thousands each year or spare you an unexpected bill.
Mortgage Interest Deduction
Mortgage interest on a second home is deductible the same way as on a primary residence if you itemize. For mortgages taken out after December 15, 2017, 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 $1,000,000 limit.19Internal Revenue Service. Real Estate Taxes, Mortgage Interest, Points, Other Property Expenses If you rent the second home part of the year, you must use it personally for more than 14 days or more than 10 percent of the rental days, whichever is longer, to keep the deduction.20Internal Revenue Service. IRS Publication 936 – Home Mortgage Interest Deduction
Property Taxes and the SALT Cap
Second-home property taxes are deductible but fall under the state and local tax deduction cap, which limits the total of state income taxes, local taxes, and property taxes you can deduct federally. If your primary home’s property taxes and state income tax already max out the SALT limit, the second home’s property taxes deliver no additional federal benefit. This is where a lot of buyers miscalculate carrying costs.
Rental Income Rules
Rent the property fewer than 15 days in a year and you don’t report any of that rental income to the IRS.21Internal Revenue Service. IRS Publication 527 – Residential Rental Property Cross the 15-day threshold and all 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, not a second home.22Internal Revenue Service. IRS Topic 701 – Sale of Your Home If the second home appreciates and you sell, you owe capital gains tax on the full profit. Some owners eventually convert a second home into their primary residence and live in it for at least two of the five years before selling to claim the exclusion, though the IRS applies additional rules to properties that weren’t always primary.
Insurance and Ongoing Costs
Homeowners insurance on a second home almost always costs more than comparable coverage on a primary residence. The property sits unoccupied for stretches, raising the risk of undetected damage from burst pipes, theft, or vandalism. Location drives much of the premium: a coastal home in a hurricane zone or a mountain cabin in wildfire country carries higher base rates and often elevated deductibles for wind or fire damage. Pools and hot tubs add liability exposure and push premiums higher.
If you plan to rent the property even occasionally, standard homeowners coverage may not be enough. Rental activity introduces commercial-level liability, and your insurer may require an endorsement or a separate landlord policy. Add property taxes (typically without the homestead exemptions many states offer on primary residences), HOA fees if applicable, maintenance on a home you can’t check daily, and possibly a property manager. Ongoing costs can easily add 2 to 4 percent of the home’s value per year on top of the mortgage payment.
Check Local Rental Rules Before You Buy
If your plan involves renting the property when you’re not there, research short-term rental laws before making an offer. A growing number of cities and counties restrict or ban short-term rentals, require special licenses, cap the number of rentable days per year, or prohibit non-owner-occupied rentals entirely. HOAs add another layer, and many governing documents flat-out prohibit rentals shorter than 30 days. Buying with a rental strategy and then finding out local rules make it illegal is an expensive mistake, and it’s becoming more common as regulation expands. Read the zoning code, any HOA covenants, and the municipality’s licensing requirements before you close.
