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 Reims: Champagne house cellar tours; Reims Cathedral; the Avenue de Champagne in Epernay; the vendanges grape harvest. Guests I price for: wine tourists and couples on 2 to 3 night stays in central Reims and along Epernay's Avenue de Champagne. Where I start: harvest-season and festive premiums around the Champagne houses, fast TGV weekend demand from Paris, and French registration for the vineyard villages.
We set up PriceLabs or Wheelhouse together with harvest and December events loaded, two-night weekend rules for Paris visitors and quieter-weekday floors. Booking.com and Vrbo then match Airbnb on fees and minimum stays, which matters for couples comparing several channels.
The service in general is described on my airbnb revenue forecast page; this page covers how I apply it in Reims.
