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 Galveston: Summer beach season; Galveston Mardi Gras; Cruise departures; Houston weekend travel. Guests I price for: Houston-area families on 2 to 4 night stays and cruise passengers on 1-night stays. Where I start: Summer weekend premiums, pre-cruise pricing, and hurricane-season floors.
With Galveston hosts I set up PriceLabs or Wheelhouse so sailing-day single nights are allowed at the right rate, summer weekends keep their minimums, and September floors step down automatically, with Airbnb, Vrbo and Booking.com all reading from the same set of rules.
The service in general is described on my airbnb revenue forecast page; this page covers how I apply it in Galveston.
