What is a good rental estimate tool for agents?
How the rent engine works
For each property, ReSharpe pulls the nearest comparable closed leases and adjusts for bedrooms, baths and geography, with a self-lease signal where the same unit has rented before. It then reports a conservative figure and the comps behind it, so the number is auditable rather than a black box. The full test design — walk-forward, out-of-sample — is on the methodology page.
Why comps beat ZIP averages
Two units in the same ZIP can rent hundreds of dollars apart based on condition, building and water access. A ZIP-level average smears those differences away and leaves you underwriting on a number that fits no actual unit. Comparable closed leases keep the estimate anchored to what's truly transacting next door. That rent flows straight into the deal analysis — cap rate, cash-on-cash and your max offer.
Frequently asked questions
- How accurate are ReSharpe's rent estimates?
- On out-of-sample backtests against real closed leases, the median error is about 7%. Each estimate is built from the nearest comparable closed leases and shows the comps it used, so you can audit it.
- How is this different from a per-ZIP rent average?
- A ZIP average treats a renovated waterfront 2/2 and a dated inland 2/2 as the same. ReSharpe estimates from the closest comparable closed leases, adjusting for bedrooms, baths and geography, instead of applying one flat number to a whole ZIP code.
- What data are rent estimates based on?
- Real closed leases from live MLS data — 46,000+ across South Florida and growing — not scraped listing asks or stale public records.
