Short-term rentals (STRs) on platforms like Airbnb and VRBO can generate significantly more revenue than traditional long-term rentals — but they also carry significantly higher expenses, operational demands, and regulatory risk. Proper STR analysis requires a different framework than long-term rental analysis. You're not analyzing a passive investment; you're analyzing a hospitality business that happens to own property.
The STR Revenue Model — What Actually Drives Income
STR revenue has three levers: Average Daily Rate (ADR), Occupancy Rate, and seasonality. Total annual revenue = ADR × Occupied Nights.
- ADR: What guests pay per night on average. Ranges from $80/night for a budget urban apartment to $500+/night for a premium beach house
- Occupancy Rate: Percentage of available nights booked. 60-70% is strong for most markets
- RevPAN: Revenue Per Available Night = ADR × Occupancy. This is the single metric to compare STRs apples-to-apples
Example: $180 ADR × 65% occupancy = $117 RevPAN × 365 nights = $42,705 gross annual revenue.
STR Expense Ratios — The Real Numbers
This is where most STR investors get surprised. Typical STR expense breakdown as a percentage of gross revenue:
- Property management: 20-30% (if using a manager or co-host)
- Platform fees: 3-5% (Airbnb host fee)
- Cleaning: 8-15% (per-turnover costs, multiple times per month)
- Supplies and restocking: 3-6%
- Utilities (owner-paid): 5-10%
- Furnishings and replacement: 3-5% annually
- Insurance (STR-specific policy): 2-4%
Total operating expenses: 45-65% of gross revenue — substantially higher than the 35-45% on a long-term rental. Always underwrite to 50%+ expense ratio on STRs before counting mortgage.
Regulatory Risk is Real: Cities including New York, San Francisco, Seattle, and hundreds of others have imposed strict STR regulations — permit requirements, primary residence restrictions, night caps, and in some cases outright bans. Before buying an STR, verify current local regulations AND the political trajectory. What's legal today may not be legal in 18 months.

The market matters more in STR than in any other real estate strategy. Look for:
- Proven STR demand: Consistent tourism, business travel, or event-driven demand (not just summer peaks)
- STR-friendly regulation: Check current rules and review city council voting history
- Strong RevPAN data: AirDNA market grades of A or B show healthy supply/demand balance
- Year-round occupancy: Avoid markets that are 90% seasonal — your mortgage doesn't take summers off
DSCR Financing for Short-Term Rentals
Traditional lenders won't count projected STR income for qualification. But DSCR lenders have adapted — many now offer STR DSCR loans that use market rent data or STR revenue estimates from tools like AirDNA's Form 1007 STR report. Expect higher rates (0.5-1% above standard DSCR) and LTV limits around 75%. Read the full DSCR loan guide before financing an STR purchase.
