How Our Market Figures Are Computed
Every number on this site is a descriptive statistic computed from recorded public county transactions — never an estimate, projection, or model output. This page documents exactly how.

What data are the figures built from?
Public Colorado county records (county assessor and clerk filings), aggregated. We aggregate recorded deeds and the assessor attributes of the parcels they convey. Nothing is sourced from listings, asking prices, broker opinions, or third-party estimates.
Which sales qualify?
Only qualified arm's-length transfers are counted: the warranty-deed family. Quitclaim deeds, tax and treasurer's deeds, estate transfers, and nominal-consideration transfers are all excluded, because their recorded prices don't reflect market value. We also count only single-parcel sales — when one deed conveys several parcels, attributing the combined price to any one parcel would overstate it, so assemblages are excluded entirely.
How are the statistics computed?
Commercial and industrial segments are reported as the median sale price with the 25th–75th percentile range, so one outlier sale can't move the figure. Vacant land is reported as the median price per acre, computed over parcels of half an acre or more.
When is a number suppressed?
A segment is published only when it clears 10 qualified sales in the window. Thinner cells are omitted rather than estimated — if a city's page shows no figure for a segment, that means there wasn't enough recorded evidence to publish one, not that we couldn't make one up.
How fresh is the data?
Trailing 24 months (sales on/after 2024-06-01). Figures were last rebuilt in June 2026. Recording lags mean the most recent few weeks of sales may not yet appear in county systems.
What are the limitations?
Figures are descriptive statistics from recorded transactions, not appraisals or opinions of value. Individual properties vary widely. The medians describe what sold, not what any specific property is worth: they make no adjustment for building condition, lease terms, entitlements, or location within a city. Recorded consideration can occasionally include non-realty components. For an opinion of value on a specific parcel, consult a licensed appraiser or broker.
