Short-term rental potential: what Airbnb math actually looks like

STR income is real — but the numbers on the listing aren't the numbers you'll see.

Scenario

Tanya is considering buying a 2BR/2BA condo near a popular Atlanta destination for $285,000. A seller's agent shows her an AirDNA report claiming the property averages $3,800/month in gross STR income. Tanya's mortgage would be $1,950/month. She thinks she's found a cash cow. What she hasn't priced in is platform fees, management, furnishing, turnover, taxes, and what happens when STR regulations change.

STR income reality check

  • Gross revenue: $3,800/month (seller's claim)
  • Platform fees (Airbnb ~3%, guest fees vary): -$114
  • Management fee if outsourced (20–30%): -$760
  • Cleaning per turnover (~$120 × 8 turns/month): -$960
  • Supplies, maintenance, HOA, utilities: -$400
  • Net income before mortgage: ~$1,566/month

Risks unique to STR

  • HOA or municipality may restrict or ban STR
  • Seasonality — not all months perform equally
  • Market saturation affects occupancy and rates
  • Guest damage, bad reviews, platform deactivation
  • STR income is taxed differently — self-employment tax may apply

Things to consider

  • Verify the HOA rules — can you legally STR this property?
  • Check local municipality STR licensing requirements and restrictions.
  • Run the numbers at 60% occupancy, not the best-case scenario.
  • What does this property cash flow as a long-term rental if STR stops working?
  • Do you have the bandwidth to manage bookings, turnovers, and guest issues?

BRIK takeaway

STR income can be strong — but gross revenue is not cash flow. Model the deal with realistic expenses, realistic occupancy, and a backup plan if regulations change. The best STR investments also work as long-term rentals at a minimum — so you're never forced to sell if the short-term market shifts.
