Jamestown 80455 is in Boulder County, CO, part of the Denver Metro. The typical home value in Jamestown 80455 is $534,904 (Zillow Home Value Index, September 2026), down 1.5% from a year earlier. Homes that sold went under contract in a median 43 days, and 0% of listings took a price cut (Redfin Data Center, period ending Sep 30, 2026).

Redfin market data (county + ZIP), via Lotvox. As of 2026-09-30. 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 (0 new, 5 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 +1.9% YoY in Boulder, CO (county), but the under-$500k tier is -1.2% — the rise is mix shift, not appreciation. Over the same year the under-$500k share of sales moved from 22.2% to 21.6% (-0.6pp) and the $1M+ share from 28.2% to 29.2% (+1.1pp).
