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 Brittany: Saint-Malo, Dinard and the Emerald Coast; Mont-Saint-Michel day trips; Ferry arrivals from Portsmouth and Poole; Quimper, the Crozon peninsula and the Gulf of Morbihan. Guests I price for: French and British families on weekly summer stays and Parisians on long weekends. Where I start: Summer weekly rates, May bridge-weekend premiums and Saint-Malo's short-term rental quotas.
I set up the pricing tool with May bridges as named events, weekly summer minimums, tide and festival weekends as small premiums and a low winter floor. Calendars are synced with Abritel and Gîtes de France so no week is double booked.
The service in general is described on my airbnb revenue forecast page; this page covers how I apply it in Brittany.
