To finance a vacation rental property, you’ll take out either a second-home mortgage or an investment-property mortgage, and the choice between the two is not yours alone — it depends on how you’ll use the property and who controls the bookings. Expect 10% to 25% down, an interest rate roughly 0.5 to 0.875 percentage points above primary-residence pricing, stricter reserve requirements, and either full personal-income underwriting or a specialized loan that qualifies on the property’s rent instead of your paycheck. The rest of the decisions flow from those first two forks.
Second Home or Investment Property
Fannie Mae and Freddie Mac, which set the guidelines for most conventional mortgages, draw a hard line between these two categories, and the classification determines your down payment, rate, and reserves.
A second home under Fannie Mae’s rules must be a one-unit dwelling you occupy for part of the year, and you must have exclusive control over it. The property cannot be subject to any agreement that gives a management firm control over occupancy.1Fannie Mae. Occupancy Types That requirement trips up many buyers: if you plan to list through a full-service management company that decides when guests book, the property likely won’t qualify as a second home.
If the lender identifies rental income from the property, the loan can still be delivered as a second home, but only if that rental income is not used to help you qualify for the mortgage.1Fannie Mae. Occupancy Types The moment you need the projected rent to meet the debt-to-income ratio, or a management company controls bookings, the property gets reclassified as an investment property, with a higher down payment and tighter standards across the board.
How Much You’ll Put Down
For a single-unit second home, Fannie Mae allows a loan-to-value ratio up to 90%, meaning as little as 10% down on a purchase.2Fannie Mae. Eligibility Matrix Investment properties require more — typically a minimum of 15% to 25% depending on the number of units and the loan program. Most lenders set the practical floor at 20% to 25% for a single-unit investment property because the pricing adjustments below that threshold get punishing.
Put less than 20% down on a second home and you’ll owe private mortgage insurance, just as with a primary residence. That added monthly cost narrows the gap between a smaller and larger down payment, so run the numbers both ways.
Why Your Rate Will Be Higher
Even after meeting the down payment minimum, vacation rental borrowers face loan-level price adjustments (LLPAs), fees Fannie Mae charges based on the property type and your loan-to-value ratio. These adjustments get folded into your interest rate and add up fast.
For both second homes and investment properties, the LLPA starts at 1.125% of the loan amount when the LTV is 60% or below, climbs to 3.375% at 75%–80% LTV, and reaches 4.125% above 80% LTV.3Fannie Mae. LLPA Matrix On a $400,000 loan at 75%–80% LTV, that 3.375% adjustment translates to $13,500 in additional cost, which lenders typically spread across the life of the loan as a higher rate. The LLPA is doing most of the work behind the 0.5 to 0.875-point premium over primary-residence rates.
A larger down payment doesn’t just reduce your loan balance — it drops you into a lower LLPA tier. If you’re close to a tier boundary, scraping together a few extra percentage points can save tens of thousands over the life of the loan.
Credit, DTI, and Reserves
Fannie Mae’s automated underwriting doesn’t publish a single hard minimum credit score for second homes or investment properties, but individual lenders set their own floors. In practice, most want at least 680 for a second home and prefer 700 or above for an investment property. A score under 680 sharply limits your options, and anything under 640 will likely shut you out of conventional financing.
Your debt-to-income ratio generally needs to stay at or below 43% to qualify for a conventional mortgage.4Fannie Mae. Debt-to-Income Ratios Some lenders allow up to 45% or 50% with strong compensating factors like large reserves or a high credit score, but 43% is the comfortable ceiling.
Reserve requirements differ by property type. Fannie Mae requires two months of PITIA — principal, interest, taxes, insurance, and association dues — for a second home, and six months for an investment property.5Fannie Mae. Minimum Reserve Requirements Those reserves must sit in verified accounts after your down payment and closing costs are paid; they can’t overlap with the money you’re spending to close. Retirement and brokerage accounts count, but lenders discount their value to account for liquidation penalties and market risk.
How Rental Income Counts
If you’re buying an investment property and plan to use projected rental income to qualify, lenders don’t credit you the full amount. Fannie Mae requires them to multiply gross monthly rent by 75% and use that reduced figure for qualifying.6Fannie Mae. Income from Rental Property in DU The 25% haircut is meant to account for vacancy and maintenance. A comparable rent schedule showing $3,000 per month translates to $2,250 of qualifying income.
For a second home, rental income cannot be used to qualify at all if you want the more favorable second-home classification.1Fannie Mae. Occupancy Types You must qualify on personal income and existing assets alone. Many buyers hit the wall here: they can afford the property if they count the Airbnb revenue, but the second-home loan they want won’t let them.
Loan Options
Conventional Financing
Conventional loans backed by Fannie Mae or Freddie Mac are the most common path for buyers who can qualify on personal income. They offer both fixed and adjustable rates and terms up to 30 years. The trade-off is that you carry the full weight of the underwriting standards described above. Rates are higher than on a primary residence but remain well below non-qualified mortgage products, so if your personal financial picture is clean and your DTI has room, a conventional loan almost always offers the lowest total borrowing cost.
DSCR Loans
Debt Service Coverage Ratio loans are a specialized product for investors who can’t or don’t want to qualify on personal income. Instead of verifying W-2s and tax returns, the lender evaluates whether the property’s rental income covers the mortgage payment. That makes DSCR loans useful for self-employed borrowers with complex returns or investors already carrying heavy personal debt from other properties.
The DSCR itself is the property’s net operating income divided by the total annual debt service (principal, interest, taxes, and insurance). A ratio of 1.0 means the property exactly covers its mortgage; most lenders want at least 1.25. Some go as low as 1.0 with pricing adjustments, but anything below signals the property can’t sustain itself.
The flexibility costs you. DSCR loans typically carry rates 1 to 3 percentage points above conventional, and most include prepayment penalties that lock you in for one to five years. A common structure is a declining penalty of 5% of the balance in year one, 4% in year two, and so on, though six months of interest on any prepaid amount is another standard approach. These loans work best when you plan to hold the property at least three to five years.
Home Equity and Cash-Out Refinancing
If you own a primary residence with significant equity, tapping into it can fund part or all of a vacation rental purchase. A home equity line of credit (HELOC) lets you borrow against your home’s appraised value, with many lenders allowing a combined loan-to-value ratio up to 80% or 85%. Because the HELOC is secured by your primary residence rather than the rental, rates are typically lower than investment-property mortgages. The risk is that you’re putting your home on the line for a rental venture.
Cash-out refinancing works similarly: you replace your existing primary-residence mortgage with a larger one and pocket the difference. The math only works if your current mortgage rate is close to or below prevailing rates. Refinancing from a 3% mortgage into a 7% mortgage to free up cash is a losing proposition for most borrowers.
Seller Financing
Seller financing is less common but real: the current owner carries the loan instead of a bank. Under federal rules stemming from the Dodd-Frank Act, sellers who aren’t in the lending business can finance up to three property sales in a 12-month period without being regulated as a loan originator, provided the loan is fully amortizing with a fixed or appropriately adjustable rate. These deals can bypass conventional underwriting hurdles but require negotiation on rate and terms and are formalized through a promissory note and deed of trust recorded with the county.
Documents to Gather
Whichever loan you pursue, assemble the paperwork before you apply:
- Two years of W-2s and federal tax returns, plus recent pay stubs. Self-employed borrowers add profit-and-loss statements and business tax returns.7Fannie Mae. Documents You Need to Apply for a Mortgage
- The most recent 60 days of checking and savings statements, showing the source of your down payment and reserves.
- Statements for retirement accounts, brokerage accounts, and any other real estate you own.7Fannie Mae. Documents You Need to Apply for a Mortgage
- Historical occupancy data or a short-term rental market report from a local management firm, if the lender will count projected rent toward qualifying.
The standard application is the Uniform Residential Loan Application, Form 1003.8Fannie Mae. Uniform Residential Loan Application – Form 1003 Misclassifying the property’s intended use or omitting rental income from other properties can flag underwriting problems that delay or derail closing.
What Closing Will Cost
Expect closing costs of 2% to 5% of the purchase price, though the effective cost is often higher on a vacation rental because LLPA pricing adjustments get factored into your rate or paid as upfront points. Budget for the appraisal, title search, title insurance, recording fees, origination fees, and any prepaid taxes or insurance the lender requires you to escrow. For investment loans where rental income is used to qualify, the appraiser also completes Form 1007, the Single-Family Comparable Rent Schedule, which estimates fair market rent based on nearby comparables.9Fannie Mae. Appraisal Report Forms and Exhibits The lender applies the 75% multiplier to that figure when calculating qualifying income.10Fannie Mae. Rental Income
Two Things to Confirm Before You Commit
Local Short-Term Rental Rules
This is the step first-time buyers most often skip, and it can be the most expensive mistake in the process. Hundreds of cities and counties regulate or outright ban short-term rentals through zoning, licensing, occupancy limits, and residency rules that may require you to live on-site. Penalties for operating without a permit range from a few hundred dollars to thousands per violation, and some jurisdictions suspend permits for repeat offenders. Before you close, verify the property’s location permits short-term rentals, check whether permits are still available (some areas cap the total number), and budget for annual licensing fees, which commonly run $100 to $600.
Insurance
A standard homeowners policy is built for a home you live in and generally won’t cover a property you rent to short-term guests on an ongoing basis. If a guest is injured and your policy excludes rental activity, you’re personally liable. At minimum, vacation rental owners need a landlord or specialized short-term rental policy that covers property damage, lost rental income when the property becomes uninhabitable, and liability for guest injuries. Many lenders require proof of appropriate coverage before closing.
Liability is the biggest concern. Industry guidance typically recommends at least $1 million in commercial general liability coverage, with $2 million preferred if the property sees heavy guest traffic or has features like pools or hot tubs. An umbrella policy adds another layer above the base coverage. Premiums are meaningfully higher than a standard homeowners policy, and they can be the difference between a property that cash-flows and one that doesn’t, so build them into your monthly cost projections before you sign anything.
