Market appraisals for estate agents
Every recent sale near the property, scored and compared per square foot, with three asking-price strategies, in minutes.

The pricing problem, in plain sight
Every valuation appointment comes down to one figure, and too many instructions go to whoever quotes highest. Then the price reductions start.
Sold prices from the portals give you an address and a figure, but not the size of the home, not a like-for-like comparison, and not the reasoning a vendor can follow.
AppraisalGPT was built for the moment the vendor asks “why this figure?” Every nearby sale, compared per square foot, scored, and set out with the evidence on the page.

Everything behind the figure
One search returns the sales, their floor areas, the scores, and the figure they point to. Each piece feeds the next, so the appraisal never contradicts itself.
Every nearby sale, not a hand-picked few
All full-value sales on the public record around the property, filtered to the same house type: detached, semi-detached, terraced or flat.
Like for like, per square foot
Floor area from each home's energy certificate, so a 680 sq ft terrace is compared with terraces its size, not just its street.
Every comp scored and ranked
A 100-point score for distance, size, price and recency, and the sales left out are shown with the reason.
Street and aerial views of every comp
A front view and an aerial with the property ringed, so the garden and the extension at the back are part of the evidence.
An asking price the vendor can follow
Offers over, guide price, and test the market, with the comparable evidence behind each figure.
A market appraisal with your name on it
A branded PDF for the vendor, written as a market appraisal of the asking price, not a RICS valuation.

The deliverable
Every appraisal ends in the conversation that wins the instruction: what the home should sell for, where to pitch the asking price, and the sales behind every figure.
