No list price. Ever.
List price is what a seller hopes. Training on it produces a tool that echoes the ask. It is banned from the model's inputs, the valuation comes from what the property is, where it sits, and what comparable buyers actually paid.
● Methodology Read in ~4 minutes
Three commitments hold everything else up: the model never sees the seller's ask, it is only ever graded on sales it never trained on, and a new model ships only when it proves itself on real closes.
List price is what a seller hopes. Training on it produces a tool that echoes the ask. It is banned from the model's inputs, the valuation comes from what the property is, where it sits, and what comparable buyers actually paid.
Testing is chronological: the model trains on earlier sales and is graded on later ones, the way it will actually be used. Random splits flatter a model. Ours is scored on 3,126 held-out BC sales, refreshed as the market moves.
Every retrain competes against the reigning model on the same held-out sales, and is promoted only when it wins. What reaches you is always the strongest model we've produced.
● Inputs
What is it? Where is it? What's the land worth versus the building? What's the market doing this month? What did nearly-identical properties close at? Each signal earns its place, every one measurably sharpens the estimate.
Each signal earns its place, the full feature list is proprietary.
● Continuous improvement Validated on held-out BC sales
The production model is refined continuously, each improvement validated on thousands of BC sales it never trained on before it ever reaches you.
Every release is proven on ~3,100 chronologically held-out BC sales: the model is always tested on the future, never the past.
● Two models, two questions
The core valuation model. Prices any Island property from its fundamentals, no listing required, no ask consulted. This is the number for CMAs, acquisition targets, and portfolio marks.
R² 0.80
A second model reads every active Island listing against its ask: predicted close price, over/under-pricing flags, and the odds of an offer in the next 30, 60, and 90 days.
Typically within 1.75% of close price
