How AI property valuation actually works (and where it falls short)
“AI valuation” sounds like a black box, but the model underneath is closer to what an appraiser already does — automated, and applied consistently at scale.
Step one: find comparable sales
The model starts with a pool of recent transactions in the same building, then the same community, filtered by property type, size band and bedroom count. Recency matters most.
Step two: adjust for differences
A comparable-sales model applies adjustments for the differences that actually move price: floor level, view, finish quality, layout efficiency, and handover status.
Step three: produce a range, not a single number
Real markets clear within a band, shaped by negotiation and buyer competition. A responsible model outputs a fair-value range (typically ±5–6%) rather than false precision.
A model is only as good as the comparables feeding it. Thin data means a wider, less confident range — and that should be visible, not hidden.
Where automated valuation genuinely falls short
- Unique or heavily renovated units with few true comparables.
- Thin markets — newly launched buildings with only a handful of resales.
- Legal, mortgage and court purposes, which require a licensed, RERA/DLD-registered valuer.
- Off-market context a model can't see, like a seller needing to close in ten days.
