How it works.
Type the address.
We pull beds, baths, square footage, and year built straight from Martin County records — you confirm, we run.
We read the closed leases.
Every comparable is a real lease a tenant actually signed, screened to the annual market — seasonal listings are excluded so snowbird pricing never skews your number.
You get the range — and the receipts.
Low, target, high, a confidence score, and every line-item adjustment shown. Then the full branded report by email, if you want it.
Stress-tested against reality
We test it against rents we know are real.
The engine is calibrated against a standing battery of ground-truth properties — actual leases with known rents, including leases on our own brokerage's books — and no methodology change ships until it passes the full battery. The flagship blind test: a 3-bed, 2-bath home in Hibiscus Park, Stuart, managed by our office and unknown to the engine. It called a target of $2,869 sight-unseen. The actual lease on our books: $2,950 a month. Within 2.7%, with the true rent inside the range.
Tested honestly, retested on every change. We publish our method below — judge it like a pro would.
The same Market Comparison Approach the licensed pros use.
Comparables come from closed MLS leases — actual signed rents, the strongest evidence that exists. The pool is screened to the annual market: roughly one in four Martin County rental listings is seasonal or dual-mode, and those prices never touch your number.
Each comp is then adjusted to your property line by line — size, bedrooms, baths, age, pool, waterfront, property type — in the tradition of the Fannie Mae Form 1007 rent schedule, with every adjustment shown on the report. The range is reconciled from the adjusted evidence, broker-reviewed, and version-stamped.
When the evidence is thin, we say so. A wide range with a warning beats a precise-looking guess.
Why this beats a national estimate.
Questions, answered.
How accurate is the Rent-Range Finder?
The engine is stress-tested against a standing battery of ground-truth properties — real leases with known rents, including leases on our own brokerage's books — and every methodology change must pass the full battery before it ships. In a documented blind test it called a target rent within 2.7% of an actual running lease on a property it had never seen. Every report carries a confidence score, and when the evidence is thin we widen the range and say so rather than fake precision.
What data does it use?
Actual closed MLS leases in Martin County, Florida — what tenants really signed, not asking prices — plus county property records for the subject's facts. The lease pool is screened to the annual market (seasonal listings excluded) and refreshed nightly.
Is it really free?
Yes. The on-screen result is free with no sign-up; the full emailed report costs only your email address. No account, no password, no verification round-trip.
What is a good rent estimate for Stuart, FL?
The median asking rent for annual leases in Martin County, Florida is currently $2,500 per month, based on active MLS listings. For a specific property, run the exact address above — neighborhood, size, and condition move the number meaningfully.
Why is my range wide?
A wide range means the closed-lease evidence near your property is thin — common for unusual or luxury homes. We flag it honestly and offer a free personal review by our broker rather than printing a precise-looking guess.
Is this an appraisal?
No. It is a broker-reviewed market analysis using the Market Comparison Approach. For a formal appraisal, consult a licensed real estate appraiser.
Do you cover counties besides Martin?
Not yet. We cover Martin County, Florida — deeply — because that is the market our brokerage leases in every week. Depth beats breadth for accuracy.
Worth knowing before you write the offer.
