An Airbnb revenue forecast is a month-by-month projection of occupancy, ADR and revenue for one property, set beside comparable listings. Buyers use it to test a purchase, operators use it to check an arbitrage lease, and hosts use it to set targets for a live listing.
What I plan around in Fire Island: Ferry-access beach communities from Ocean Beach to Cherry Grove and the Pines; New York City summer weekends; Car-free island lifestyle; Summer share-house tradition. Guests I price for: New York City groups on seasonal shares, weekly rentals and summer weekends. Where I start: Season, half-season and weekly pricing, ferry-schedule minimum stays, and holiday-weekend premiums.
On Vrbo and Airbnb I list only what the seasonal and share market has not taken, using PriceLabs or Wheelhouse with fixed changeovers, ferry-friendly arrival days and holiday-weekend premiums, so platform bookings fill gaps rather than undercut the summer you already sold privately.
The service in general is described on my airbnb revenue forecast page; this page covers how I apply it in Fire Island.
