Overview
Short-term rental mortgages are mortgages and underwriting approaches designed for properties primarily used for short-term stays (Airbnb, Vrbo, direct vacation bookings). These loans recognize that the borrower’s repayment ability can come from rental cash flow as well as personal income. Lenders vary widely in how they verify and count short-term rental income; some will rely on historical tax records or platform statements, while others prefer conservative pro forma analyses or specialized debt-service-coverage-ratio (DSCR) underwriting used by non‑QM lenders (Consumer Financial Protection Bureau).
In my experience working with borrowers and mortgage teams, the lenders most willing to finance short-term rental properties fall into two groups: conventional lenders who treat the property as a second home or investment property under standard guidelines, and specialty lenders who underwrite to cash flow (DSCR or bank statement loans). Understanding the differences helps you shop for the right product and avoid underwriting surprises.

What types of mortgage products will finance short-term rentals?
- Conventional conforming loans: Many banks and mortgage companies will finance a short-term rental as an investment property or—less commonly—a second home. Underwriting follows standard investor or second-home rules, but lenders may require evidence the property can operate as a short-term rental and may treat occupancy/use risk more conservatively.
- Portfolio loans: Local banks or credit unions may keep loans on their books and apply flexible underwriting for vacation rentals, often when the borrower has a strong relationship or the local market is well understood.
- DSCR and cash-flow loans (non‑QM): These lenders underwrite using Debt-Service Coverage Ratio—monthly net rental income divided by proposed mortgage payment—rather than the borrower’s W‑2 income. DSCR loans are popular for Airbnb investors who can document strong short-term rental performance.
- Bank-statement loans: For hosts who can’t show qualified W‑2 or Schedule E income, lenders may accept 12–24 months of bank deposits to build an income picture.
- FHA/VA: Government programs have strict occupancy and use rules. FHA loans expect owner occupancy and generally aren’t intended for properties used primarily as short-term rentals; VA similarly expects the borrower to occupy the home as a primary residence. Check program rules before assuming eligibility (U.S. Department of Housing and Urban Development).
How do lenders calculate and verify short-term rental income?
Lenders use several methods, often combining data sources to be conservative:
- Tax returns (Schedule E): The most durable proof is consistent rental income reported to the IRS on Schedule E. Lenders commonly average two years of Schedule E income and may apply vacancy or expense reductions.
- Platform statements and booking histories: Some lenders accept Airbnb or Vrbo host statements, calendar exports, or 1099‑K records when a property has been listed long enough to show a stable pattern.
- Appraisal with rental schedule or rent analysis: An appraiser or third‑party market rent report can create a pro forma monthly income estimate; lenders reduce that figure for expected vacancy and operating costs.
- Bank statements: Lenders may analyze 12–24 months of deposits tied to rental activity, particularly with bank‑statement loan products.
- DSCR calculation: For DSCR loans the lender requires proof of net operating income (NOI) and calculates whether projected NOI covers the mortgage at a required coverage ratio (often 1.0–1.25x, depending on lender).
Expect conservative adjustments: lenders often discount gross platform receipts for service fees, taxes, and vacancy. Many use a 25–40% reduction as a rule‑of‑thumb to reach a conservative net income estimate.

Typical underwriting and eligibility factors
- Credit score and debt-to-income (DTI): Investment and short-term rental loans generally require stronger credit profiles than owner-occupied loans. Typical lender minimums: mid-600s for many portfolio/non‑QM lenders; higher scores improve pricing.
- Down payment: Investment property down payments commonly start at 15–25% but vary widely by lender and product. Second-home programs may accept lower down payments if the borrower occupies the property seasonally and company policy allows.
- Reserves: Lenders often require cash reserves sufficient to cover multiple months of mortgage payments—sometimes 6–12 months for investment properties.
- Income documentation: Lenders want history (tax returns, 1099‑K, platform records) or alternative documentation such as bank statements or pro forma appraisals.
- Insurance and local compliance: Proof of appropriate insurance (landlord or commercial short-term rental coverage) and evidence of local permits or code compliance are frequently requested.
Specific rules and thresholds vary by lender and product; talk with a mortgage broker or lender experienced in short-term rentals to get exact requirements for your scenario.
Taxes, accounting, and regulatory considerations
- Tax reporting: Short-term rental income is taxable and typically reported on Schedule E (or Schedule C if services provided rise to a business level). IRS Publication 527 explains rental tax rules and the difference between rental and business income.
- Personal-use tests: If you use the property personally for many days, tax treatment changes and may reduce deductible losses. The IRS and tax advisers can clarify how personal use affects depreciation and deductions.
- Local rules and permits: Many cities and counties require short-term rental permits, business licenses, safety inspections, or limit days of rental. These rules affect the property’s legality and lender willingness to finance.
- Insurance gaps: Standard homeowner policies usually exclude short-term rental exposures. Consider landlord or specialized short-term rental policies; see our guide on insuring short-term rentals for gaps and solutions (insuring short-term rentals).

Practical underwriting examples (illustrative)
- Example A — Conventional investor loan: Borrower has 2 years of Schedule E showing $24,000 annual net income from a beach house. Lender averages and applies a 25% vacancy/expense cushion; underwriter counts $18,000 toward qualification and approves an investment-property loan with 20% down.
- Example B — DSCR loan: Borrower lacks strong W‑2 income but has 18 months of Airbnb statements showing solid net cash flow. A DSCR lender calculates NOI and requires a minimum coverage ratio of 1.15; the loan is priced as a non‑QM product and requires higher reserves.
These are simplified examples; actual approvals depend on lender overlays and borrower credit profile.
Strategies to improve approval odds
- Work with a lender experienced in short‑term rentals—specialists understand how to document platform income and build credible pro formas. In my lending practice this reduces delays and document churn.
- Build documentation: keep tax returns, 1099‑K statements, booked calendar exports, and 12–24 months of bank statements organized before applying.
- Use conservative projections: lenders prefer realistic forecasts; overstated occupancy or nightly rates can trigger appraisal or underwriting pushback.
- Clean title and insurance: ensure the property has transferable title, and secure landlord/short-term rental insurance early in the process.
- Consider an LLC for liability protection, but be aware some lenders require personal guarantees or will not lend to entities—discuss structure with legal and lending advisors (see using LLCs for rental property liability protection).
Common mistakes to avoid
- Assuming every lender treats Airbnb income the same—their documentation and acceptance rules differ dramatically.
- Failing to verify local short-term rental legality before purchase. If the city prohibits the use, financing and long-term value suffer.
- Over-relying on projected income without history. Lenders prefer documented evidence; newly listed properties often need more reserves or different loan products.

Frequently asked questions
Q — Can I use a conventional mortgage to buy an Airbnb property?
A — Yes, but the property will be treated either as a second home or an investment property with different down payment, pricing, and documentation expectations. Lender rules vary.
Q — Will lenders count Airbnb calendar bookings as income?
A — Some lenders will if you can produce platform statements, 1099‑Ks, or bank deposits showing consistent receipts; others require Schedule E tax history or prefer DSCR underwriting.
Q — Are short-term rental rates higher than normal investment mortgages?
A — Often yes: investment and non‑QM products typically carry higher interest rates and more reserve requirements than owner-occupied loans to reflect higher perceived risk.
