Standard trend model — solid = measured history · dashed = projection anchored at each line's last measured point, following that series' trailing pace (CAGR capped ±12%/yr) or trailing mean · projections are estimates, not measured reads · every charted series runs the standard 5-year historical window with a 1-year forecast, trimmed from the full retained ledger — the forecast always extends into the future year (a lagging ledger bridges to it) and stops there on purpose: authoritative, not wizardry · every price line is county-assessed value from the district CAD — the tier's same-parcel assessment roll-up on the momentum tile, the assessed trajectory in raw dollar levels and as a YoY-chained index (base 100), and the month-over-month pace from nearby comparable sales pooled from the research track; a tier without comps yet keeps its pace story with the assessed trend. Inventory, liquidity, price-cut and foreclosure lines run on the platform's own measured series.
