Whether you call it a short-term rental, Airbnb, holiday let, or vacation rental, the economics differ from long-term buy-to-let. Revenue depends on nightly rate and occupancy, not a fixed lease. Costs scale per booking (cleaning) and per night (tourism levies).

FastPropertyROI models STR income from nightly rate × occupied nights, surfaces ADR and RevPAR on screen and in the exported Summary sheet, and ships a tracking spreadsheet you fill in month by month — no property manager software required.

Run the calculator or open the tracking spreadsheet, enter your property details, and download an 8-sheet Excel workbook. Log monthly income and expenses, compare actuals to projections, and see STR KPIs update on the Summary sheet.
