Short-term rental investors face a financing problem that conventional lenders cannot solve. Airbnb income fluctuates by season, self-employed hosts show lower taxable income due to depreciation, and most traditional mortgage programs either ignore STR income entirely or discount it heavily. DSCR loans solve this by qualifying the property on its rental income potential rather than the borrower's personal income or employment history.
This guide covers how DSCR loans work for Airbnb and short-term rental properties, how lenders calculate income, what the qualification requirements look like, and what to watch out for before you apply.
How DSCR Loans Work for Short-Term Rentals
A DSCR loan qualifies based on the Debt Service Coverage Ratio of the property:
DSCR = Monthly Rental Income / Monthly PITIA
PITIA stands for principal, interest, taxes, insurance, and association dues. A DSCR of 1.0 means the property's income exactly covers its debt. A DSCR of 1.25 means it generates 25% more income than needed to service the debt.
For short-term rentals, lenders use projected or documented Airbnb income rather than a standard 12-month lease. This is the key distinction from long-term rental DSCR underwriting, and not every lender handles it the same way.
Example: A property generates $5,200 per month in projected STR income. The monthly PITIA is $4,000. DSCR = 1.30. The property qualifies and produces 30% more income than required to cover its debt obligations.
How Lenders Calculate Short-Term Rental Income
This is where STR DSCR loans get specific. Lenders use three main methods.
AirDNA market projections. For properties without an operating history, lenders use AirDNA or similar platforms to estimate projected gross rental income based on comparable listings in the area by location, bedroom count, property type, and amenity tier. Most programs apply a conservative haircut of 70% to 80% of the projection to account for income variability. Always confirm with your lender whether they accept AirDNA projections before applying.
12-month platform history. If the property has operated as an Airbnb or VRBO for at least 12 months, lenders can use actual gross rental receipts from your hosting platform dashboard or bank statements. Lenders typically average this over the full year to smooth out seasonal peaks and valleys.
Appraiser's long-term market rent (Form 1007). Some lenders default to the appraiser's estimate of what the property would rent for on a 12-month lease. This is the most conservative approach and typically produces a lower qualifying income than AirDNA on most STR properties. Investor-focused DSCR programs generally use AirDNA or platform history instead.
DSCR Loan Requirements for Airbnb Properties
Requirements vary by lender and program, but most STR DSCR loans share the following parameters.
Minimum DSCR ratio: Most lenders require 1.0 or higher. Properties with DSCR above 1.25 typically qualify for better rates. Some specialty programs allow ratios as low as 0.75 with larger down payments and rate premiums.
Down payment: Typically 20% to 25% for standard STR properties. Some lenders require 25% to 30% in seasonal or vacation markets due to higher income volatility.
Credit score: Most programs start around 660, with better pricing at higher scores.
Cash reserves: STR programs typically require 6 months or more of PITIA in liquid reserves, more than the 2 to 6 months required for long-term rental DSCR, because of income seasonality.
LTV: Typically 75% to 80% on purchase, with some programs going to 85% for highly qualified borrowers. Cash-out refinances are generally capped lower.
Property type: Single-family homes, condos, townhomes, and 2-4 unit residential properties. Investment use only.
The Issue That Derails Most STR DSCR Deals
Local short-term rental regulations are the most common deal killer for Airbnb DSCR loans. If short-term rental is prohibited or heavily restricted in your target market, lenders may decline the application or fall back to long-term rent comparables only.
Markets to research carefully before applying: New York City has strict 30-day minimums for most unhosted rentals. Los Angeles requires a primary residence license for most STR permits. Santa Monica has very limited STR availability.
STR-friendly markets as of 2026 include Nashville, Miami Beach (with permit), Scottsdale, New Orleans, Charleston SC, Savannah GA, and most mountain resort markets.
HOA rules also matter. Condos and townhomes with HOAs frequently prohibit rentals under 30 days. Confirm STR eligibility at the city, county, and HOA level before ordering an appraisal.
STR DSCR vs. Long-Term Rental DSCR
Short-term rental DSCR loans carry slightly higher rates than long-term rental DSCR products, typically by 0.25% to 0.50%, reflecting higher income variability. They also require higher reserves and sometimes higher down payments.
The tradeoff is income potential. In high-demand markets, STR gross yields of 12% to 20% are achievable on well-managed properties, which can produce DSCR ratios significantly stronger than the same property would generate on a 12-month lease.
