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 Portsmouth: Hampton Beach summer season; Portsmouth's historic downtown and dining; Boston weekend escapes; Kittery and the southern Maine coast nearby. Guests I price for: Boston-area couples and families on 2 to 4 night summer stays and weekly beach rentals. Where I start: Summer weekly beach rates, weekend downtown premiums, and winter floors.
On Airbnb, Vrbo and Booking.com I set up Seacoast pricing in PriceLabs or Wheelhouse with Saturday changeovers for Hampton and Rye in summer, weekend premiums downtown, event dates for graduations and the Seafood Festival, and monthly options for winter contractors, so every channel reads from the same plan.
The service in general is described on my airbnb revenue forecast page; this page covers how I apply it in Portsmouth.
