The risk
A 150 sq ft discrepancy at $250/sq ft = $37,500 appraisal gap.
Caught before listing: renegotiate the price. Caught at appraisal: explain it to your buyer.
Common workflows
Run the floor plan before the listing goes live. Catch discrepancies between the seller's claim, tax record, and actual floor plan area before they become a problem.
If your seller paid for a 3D scan, you have an accurate floor plan. PlanSnapper reads it in 60 seconds — no manual measurement, no field trip.
Compare your measurement against what the previous agent listed. If the numbers don't match, you want to know that before the appraiser finds it.
Have a buyer questioning the listed square footage? Run the floor plan together. 60 seconds of transparency beats a deal falling apart at inspection.
Basements don't count as GLA. Measure them separately and list both numbers — above-grade GLA and finished below-grade area. Buyers appreciate the transparency.
Seller claims the garage conversion added 400 sq ft? Measure from the floor plan before it hits the listing. Unpermitted space has different rules.
How it works
Export from CubiCasa, Matterport, or iGUIDE as a PNG or PDF. Screenshot it from the MLS listing. Save it from an email the seller forwarded. Any to-scale image works.
Click two points along any labeled dimension — a room width, an overall depth, a door opening. Enter the real-world measurement. Everything else is calculated from there.
Square footage appears instantly. Export the result as a PDF if you need documentation. The whole process takes under 2 minutes — faster than waiting for the appraiser to show up.
