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 Perth: Summer beach season; Margaret River wine region and Gourmet Escape; Rottnest Island; Mining and resources business travel. Guests I price for: Domestic and Southeast Asian families on 4 to 7 night stays, corporate guests midweek. Where I start: Summer and school-holiday premiums, wine-weekend rates, and corporate midweek floors.
On Airbnb and Stayz I set up PriceLabs or Wheelhouse with WA school terms rather than east coast dates, weekend logic for Margaret River and corporate weekday floors for Perth, so each listing follows the demand that actually fills it and not a national average.
The service in general is described on my airbnb revenue forecast page; this page covers how I apply it in Perth.
