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 Murcia: Mar Menor and La Manga beaches; Golf resorts and winter residents; Cartagena's Roman theatre and naval history; Murcia Holy Week and Spring Festival. Guests I price for: Spanish families on summer weeks and northern European golfers and retirees on monthly winter stays. Where I start: Summer weekly rates, monthly winter pricing and regional tourist rental registration.
I set up the pricing tool so summer weekly stays on the coast, winter monthly rates on the golf resorts and festival dates in Murcia city and Cartagena run as separate rules, with realistic floors for the quiet weeks in November and early December and clear utility terms for long stays.
The service in general is described on my airbnb revenue forecast page; this page covers how I apply it in Murcia.
