Build an income estimate you can explain
6 min read · Sources checked October 4, 2026 · Not specialist reviewed
An estimate is more useful when you know which properties and assumptions produced it.
Start with a range supported by comparable properties, then explain what makes your property different. Record the source, reporting period and limitations. Forecasts and advertised prices are evidence to investigate, not verified future income.
For short-term rentals
Inspect comparables with similar location, size, condition, amenities and guest capacity. Look at monthly occupancy and average daily rate rather than a peak-season calendar. Ask whether revenue includes cleaning charges or taxes and how unavailable nights are handled. Published availability is not proof that every unavailable night was booked.
For long-term rentals
Compare condition, size, lease terms, parking, location and included utilities. Distinguish asking rents from executed lease rents. Request a local manager’s supported range and expected leasing time. RentCast offers estimates and underlying comparables; HUD Fair Market Rents offer geographic context rather than a property-specific quote.
Use more than one kind of evidence
A seller’s claimed revenue should be reconciled to appropriate booking or financial records where available. Compare any vendor estimate with property-specific evidence and a local operating view. Investigate conflicting definitions before averaging numbers. Track uncertainty rather than hiding it in a single optimistic figure.
If a property averages $250 per paid night and 200 paid nights, room revenue is $50,000. That says nothing yet about platform fees, cleaning, management, utilities, maintenance or loan payments.
Your next action
Find several relevant comparables, document why each is comparable, and write a low/base/high income range with its dates and sources.
A mistake to avoid
Using peak nightly rates for every night of the year, or assuming an advertised LTR rent will be collected for all twelve months.
