CoBuy Suitability Score™
A proprietary algorithm that scores any home for co-ownership, and a service that delivers the score to the agent listing it.
ProofValidated across 3,777 test pairs. Cited in MLS listing remarks.
My role
Designed the model. Supplied and reconciled the calibration judgments. Directed the adversarial testing. Turned the engine into a delivered service.
Results
- A listing brokerage put the score in its MLS remarks. It showed up on Redfin and Zillow the same day.
- Our page for a scored listing ranked on page one for the address within a day.
- A broker scored his own $3.85M listing, published the scoresheet, and gave us a segment on his show.
What it is
Homes get built and sold for one household. Put two or three households in one and most of them fail: one kitchen, one entrance, one primary suite, nowhere to park.
The CoBuy Suitability Score™ grades a home on how well it works for people who’ll own it together. Agents send us a listing. We score it and hand back the grade, the reasons and the marketing materials.
It gives a co-buying group a fast answer to “would this work for us?” and gives the agent a reason to call us.
Screens
More proof
- 3,777 test pairs, zero violations.
- The engine was locked after a 4-seat adversarial review.
- Each score ships with an explanation, a scoresheet, a public listing page and a marketing kit for the agent.
