}A resale condo listing hides what buyers actually want.
Two gaps, on every resale condo: there's no floor plan, and the size is a vague MLS range — not the real number.
Finding the matching developer floor plan for an existing listing is slow, manual work. We serve it automatically from a database of tens of thousands of plans, so buyers can actually see the unit.
MLS reports size as a band — “600–699 sq ft.” We resolve the exact unit: 623 sq ft. Better for buyers, and far better for any number you calculate from it.
Every per-square-foot number inherits the error.
A 600–699 range can be ±8% off the real area. Anything computed from size compounds that — pricing, fees, valuations and comps all drift. An exact unit size makes the whole stack downstream of it accurate.
Price per square foot
A real area means a real $/sq ft — at the unit, building and market level. Ranges quietly skew every comparison.
Maintenance fees per sq ft
Fee-per-foot is a core condo metric. It’s only meaningful when the denominator is the exact size, not a 100 sq ft band.
Valuations & comps
AVMs and comp sets built on exact unit areas hold up; ones built on MLS ranges inherit and compound the error.
Matching a resale unit back to its original developer floor plan requires having collected every plan, in every project, since 2010. That archive — tens of thousands of floor plans — is the moat. It can't be scraped after the fact.

Send the listing details
POST the address, unit number, beds, baths and the size range to /api/v1/floorplan-matches. One request — the listing’s own fields, nothing special required.
We resolve the exact unit
We match it to the original pre-construction unit across tens of thousands of developer floor plans — 15 years of data — and return a confidence score.
Get the floor plan & exact size
Back comes the developer floor plan, the exact square footage, the brochure and original pricing — ready to render on the listing.
