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 The Alentejo: Comporta and Melides beaches; Évora's UNESCO centre; Alentejo wine estates; Rural design hotels and villas. Guests I price for: Lisbon weekenders and international couples and families on 3 to 7 night stays. Where I start: Coastal summer premiums, villa weekly rates and Portuguese Alojamento Local registration.
I set up PriceLabs or Wheelhouse with you so Comporta's August weeks stay protected, inland spring and autumn sit above summer, and harvest, Easter and Portuguese holidays carry their own rules, with gap logic that suits villas where every changeover costs far more than in a city flat.
The service in general is described on my airbnb revenue forecast page; this page covers how I apply it in The Alentejo.
