Build a complete project allowance
Include the equipment, delivery, site preparation, utility work, permits where applicable and installation. Request written scopes so you understand what is included and what is excluded. Keep a contingency appropriate to the project’s uncertainty. IdealZone’s demo prices are planning assumptions, not manufacturer quotes.
Model revenue and costs separately
A simple starting point is nightly rate multiplied by booked nights. Run conservative, base and optimistic scenarios rather than relying on one percentage. Then subtract additional utilities, cleaning, maintenance, consumables, service, insurance changes and applicable booking fees. Financing payments and taxes need their own treatment; do not label gross revenue as profit.
Treat amenity comparisons as clues
Market datasets can show that listings with certain amenities perform differently. Those differences can also reflect location, property quality, size and guest mix. An observed association does not prove the amenity caused the increase. Compare similar local rentals and test pricing gradually. No industry percentage guarantees your property’s outcome.
