Frequently asked questions

What is an Airbnb calculator for agents?

An Airbnb calculator estimates the cash flow, cap rate, and cash-on-cash return of a property operated as a short-term rental. Buyer's agents use it to underwrite investment listings on the spot — occupancy, ADR, cleaning, management, and financing — so investor clients can make a same-day offer decision.

How is this different from a long-term rental calculator?

Short-term rentals have very different economics: revenue is ADR × occupancy × 365 (not monthly rent), and expenses include cleaning, supplies, utilities, higher insurance, platform fees, and 20–25% management. Sumline models both — see the Airbnb vs long-term rental guide for a side-by-side.

What occupancy and ADR should I use?

Pull comparable-property data for the ZIP before underwriting. AirDNA's 2024 US benchmark is roughly 54% average annual occupancy for active listings. Strong vacation markets run 65–75%; oversupplied secondary markets 40–50%. Enter conservative and aggressive scenarios and export both PDFs for the buyer.

Can I brand the PDF report with my logo?

Yes on Estate Pro ($19/month). You get unlimited exports plus full white-label control — logo, headshot, brokerage colors, disclaimers. The free tier includes 5 unwatermarked reports per month with pay-per-PDF beyond that.

Does the calculator flag STR regulation risk?

The calculator surfaces the assumptions; regulation research is the agent's job. Cities like New York (Local Law 18), parts of Los Angeles, San Francisco, and Honolulu enforce strict permit or day-count limits. Confirm city and HOA rules before your buyer writes the offer.
