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 Marbella: Starlite Festival concerts; Costa del Sol golf season; Puerto Banus luxury tourism; Feria de San Bernabe. Guests I price for: affluent couples and golf groups on 5 to 10 night stays around the Golden Mile, Puerto Banus and the Casco Antiguo old town. Where I start: event and summer premiums on the Golden Mile, VFT tourist-licence compliance under the Junta de Andalucia, and winter golf floors that keep occupancy alive off season.
I set your pricing tool so Starlite nights, the Feria and peak summer weeks carry premiums with minimum stays, while golf weeks in spring, autumn and winter are priced for groups, with rates consistent across Airbnb, Booking.com, Vrbo and Expedia.
The service in general is described on my airbnb revenue forecast page; this page covers how I apply it in Marbella.
