Parcels & assessor attributes — Santa Monica Parcels_Public / LA County assessment roll (ODC-By). Square footage, beds/baths and year built come from the assessor and can lag unpermitted work.
Remodel status — inferred from assessor signals: effective year > year built, improvement base year reset after purchase (Prop 13 reassessment), or a house newer than its owner's land base year (= rebuilt). Cosmetic/unpermitted remodels are invisible here.
Sale prices — recorded sales; amounts derived from documentary transfer tax where shown, so they are approximate (±$455). Transfer history is reduced to what listing sites also publish: dates, prices, and sale/foreclosure/non-sale kind. Assessor document-type labels are not republished.
Estimated value — a deliberately simple comp model: recent neighborhood sales, time-adjusted $/sqft, matched on size, vintage and remodel status. A rough guide, not an appraisal or AVM.
Sell signal — a transparent 0–100 heuristic for off-market homes: owner tenure (up to +35, ramping over 25 years), recent mid-tenure non-sale transfer activity (+20), original condition held 25+ years (+15), long-hold non-owner-occupant (+10), land-dominant assessment (+10), active major permit (−25). Not a prediction, just stacked public-record signals.
★ Modern 4BR+ macro — homes built, rebuilt, or majorly remodeled since 1990 with 4+ bedrooms.
Permits — City of Santa Monica active building permits only (open permits; history accrues over time).
On-market & garage — RentCast, refreshed monthly when configured.
