Redfin market data (county + ZIP), via Lotvox. As of 2026-08-31. Normal = same-month median of monthly rates, minimum 3 same-month points. Source window 3 months (flows shown per month). months_of_supply is not published at this grain (0 non-null rows measured); derived here as active listings / closed sales per month. A fresher supply-only read (44 new, 107 active, 2026-09-01, Realtor.com inventory (county + ZIP), via Lotvox) is available but is NOT used in the net — that source publishes no closed sales, so subtracting across it would mix two vintages.

Price Bands — the median behind the median
A single median rises whenever expensive homes become a bigger share of what sells, even if no tier got more expensive. These are the tiers underneath it, computed from recorded arms-length deed transactions in Boulder.
Aggregate median -0.4% YoY in this ZIP, but the under-$500k tier is +0.9% — both are essentially flat year over year. Over the same year the under-$500k share of sales moved from 37.8% to 35.9% (-1.9pp) and the $1M+ share from 5.0% to 4.1% (-0.9pp).
