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 Nashville: CMA Fest and Bonnaroo spill-over in June; Bachelorette and group travel most weekends; Titans and Predators home games; Convention traffic at Music City Center. Guests I price for: Large groups of 8 to 16 booking 2 to 3 nights, plus couples and corporate guests midweek. Where I start: Weekend premiums and 2 to 3 night minimums for group homes, per-bedroom pricing benchmarks against a saturated East Nashville and The Gulch supply, and midweek discounting to fill Sunday to Thursday.
For Nashville hosts I configure PriceLabs or Wheelhouse with CMA Fest, July 4th, football and New Year's Eve dates loaded early, group-oriented weekend rules, midweek offers for conventions, and occupancy-based pricing benchmarked against similar group homes nearby, so the total a party of twelve sees stays competitive.
The service in general is described on my airbnb revenue forecast page; this page covers how I apply it in Nashville.
