Frequently asked questions

Why doesn't this list use the usual quality floor?
Cheapest-ZIPs lists normally include only ZIPs with HavenScore: 60 or above. No ZIP in Douglas County, CO clears that floor this month, so this page shows the county's most affordable scored ZIPs instead — with each ZIP's HavenScore shown, so the trade-off stays visible.
How is "most affordable" measured here?
ZIPs are ranked by median home value from lowest to highest across every scored ZIP in Douglas County, CO. Because no ZIP clears the quality floor this month, no score filter is applied to this list.
How often is this list updated?
This page refreshes monthly when our pipeline ingests new data from Zillow, Redfin, Census, FHFA, and FRED.
