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 Santa Barbara: Old Spanish Days Fiesta; Santa Ynez wine country; UCSB calendar; Pismo and Morro Bay beach season. Guests I price for: Southern California weekenders and families on 2 to 4 night stays. Where I start: Summer and event premiums, weekend minimums, and strict city STR ordinance compliance.
I configure PriceLabs or Wheelhouse with Fiesta, graduations and film festival dates, summer minimums and wine-country weekends. Where rules allow only longer stays, I build monthly pricing instead, and Airbnb, Vrbo and Booking.com follow the same plan, so a Fiesta weekend never sells cheaper on one channel.
The service in general is described on my airbnb revenue forecast page; this page covers how I apply it in Santa Barbara.
