Second home mortgage rates typically run 0.25% to 0.75% higher than rates on a comparable primary residence loan. The premium exists because lenders view second homes as riskier: a borrower under financial stress is more likely to walk away from a vacation property than the home they live in, and vacation-home markets can swing more sharply in a downturn. How much extra you pay depends on your credit score, how much you put down, and whether the loan stays within conforming limits.
What Drives the Rate Premium
The specific mechanism behind the higher rate is a loan-level price adjustment, or LLPA. Fannie Mae adds an LLPA to every second home loan, expressed as a percentage of the loan amount, on top of adjustments for credit score and down payment. The second-home LLPA runs from 1.125% of the loan amount at lower loan-to-value ratios up to 4.125% at higher ones.1Fannie Mae. Loan-Level Price Adjustment Matrix Lenders usually convert those upfront fees into a higher interest rate, which is why a quoted rate on a second home lands noticeably above what you’d see for a primary residence with otherwise identical terms.
Factors That Move Your Rate
Credit Score
Fannie Mae requires a minimum score of 620 for any conventional mortgage, including second home loans.2Fannie Mae. General Requirements for Credit Scores Clearing 620 doesn’t get you the best pricing. LLPAs scale up as scores drop, so a borrower in the mid-600s can see the effective rate climb an extra 0.5% to 1% compared with someone above 740.1Fannie Mae. Loan-Level Price Adjustment Matrix Below 700, pricing varies widely between lenders, so shop the loan hard.
Down Payment
The minimum down payment for a conventional second home is 10%, giving you a maximum LTV of 90%.3Fannie Mae. Eligibility Matrix Putting down only 10% is expensive: the second-home LLPA at 85–90% LTV is 4.125%, versus 1.125% if you put down 40% or more.1Fannie Mae. Loan-Level Price Adjustment Matrix A 25% down payment drops the LLPA to 2.125%, which produces meaningful savings over a 30-year loan.
If you put down less than 20%, expect private mortgage insurance, generally $30 to $70 per month for every $100,000 borrowed depending on credit and LTV. PMI stacks on top of the second-home rate premium, so a small down payment gets expensive quickly. Twenty percent down eliminates PMI.
Debt-to-Income Ratio
Your DTI includes the payment on your current home plus the new second home payment. Fannie Mae caps DTI at 36% on manually underwritten loans, with strong credit and reserves stretching it to 45%. Loans run through automated underwriting can go up to 50%.4Fannie Mae. Debt-to-Income Ratios A large existing mortgage eats into how much second home you can finance.
Cash Reserves
Fannie Mae requires at least two months of total housing payments — principal, interest, taxes, insurance, and any association dues — in liquid reserves for a second home loan.5Fannie Mae. Minimum Reserve Requirements Some lenders set higher thresholds, especially on jumbo loans.
Second Home vs. Investment Property Classification
Property classification has a bigger impact on your rate than most people expect. Investment property loans carry rates roughly 0.50% to 1.50% above primary residence rates, considerably more than the second-home premium. Qualifying for the lower second-home tier means meeting specific criteria.
Lenders generally expect a second home to sit a meaningful distance from your primary residence, often 50 miles or more, signaling a vacation or seasonal use rather than a convenience rental. The property must be suitable for year-round occupancy, and you need to maintain personal use throughout the year. You also cannot use rental income from the property to qualify. Fannie Mae’s guidelines specifically prohibit counting second home rental income in the qualification calculation.6Fannie Mae. Rental Income
Your loan application (Fannie Mae Form 1003) includes an occupancy field where you designate the property as primary, second home, or investment.7Fannie Mae.

Lenders may verify occupancy after closing through utility records, mail delivery, or post-loan audits.
Conforming Limits and the Jumbo Bump
For 2026, the baseline conforming loan limit for a single-unit property is $832,750 in most of the country, rising to $1,249,125 in designated high-cost areas.8U.S. Federal Housing Finance Agency. FHFA Announces Conforming Loan Limit Values for 2026 A second home loan that stays inside those limits can be sold to Fannie Mae or Freddie Mac, which usually means more competitive pricing.
Cross the limit and you’re in jumbo territory. Jumbo lenders typically require a larger down payment, often 20% or more, along with stronger credit and heavier reserves. Because jumbo loans can’t be sold to the government-sponsored enterprises, lenders carry more risk, and that generally shows up as a higher rate stacked on top of the second-home premium.
Why FHA and VA Loans Aren’t an Option
FHA loans cannot finance a vacation home or second residence. FHA rules require the borrower to occupy the property as a primary residence and specifically prohibit financing vacation properties or timeshares. A second FHA-insured mortgage is possible in narrow cases like a job relocation or a growing family, but not for a personal getaway.
VA loans carry the same primary-residence requirement. If you’re a veteran financing a second home, a conventional loan is generally the only route.
Don’t Try to Reclassify to Get a Better Rate
Given how much the classification affects pricing, it’s tempting to call a rental property a second home. Doing so is occupancy fraud. Because the application goes to a federally related lender, a false statement can be prosecuted under federal law. Under 18 U.S.C. § 1014, knowingly making a false statement to influence a mortgage lender’s decision carries a fine of up to $1,000,000 and up to 30 years in prison.9Office of the Law Revision Counsel. 18 U.S. Code 1014 – Loan and Credit Applications Generally A separate bank fraud statute imposes the same maximum penalties for schemes to defraud a financial institution.10Office of the Law Revision Counsel. 18 U.S. Code 1344 – Bank Fraud Even short of prosecution, a lender that discovers misrepresentation can call the loan due immediately, forcing a payoff or foreclosure.
