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 Ericeira: Ericeira World Surfing Reserve; Nazare big-wave season at Praia do Norte; Peniche surf breaks; Obidos walled town and festivals. Guests I price for: surfers and coastal travellers on 4 to 7 night stays in Ericeira, Peniche and the villages of the Costa de Prata. Where I start: a near year-round surf calendar that fills the winter big-wave months, AL registration along the Silver Coast, and swell-driven pricing rather than a simple summer peak.
I set up your pricing so surf season, summer weeks and festival dates sit in separate bands, with weekly and monthly offers for surfers and remote workers. Airbnb, Booking.com, Vrbo and Expedia all share the same rules and AL details.
The service in general is described on my airbnb revenue forecast page; this page covers how I apply it in Ericeira.
