Price bandsmix-shift

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 Douglas.

Aggregate median +1.8% YoY in Denver, CO (metro), but the under-$500k tier is -0.4% — the rise is mix shift, not appreciation. Over the same year the under-$500k share of sales moved from 38.9% to 37.2% (-1.7pp) and the $1M+ share from 10.3% to 11.3% (+1.0pp).

ZIP-level history was too thin to draw the tiers; served at metro level (Denver, CO), by quarter.

Median within each tier, against the headline median (quarterly)

The blue line is the single number NAR-style reporting quotes. The gold lines are what each tier actually did. Log scale — the tiers span an order of magnitude, and on a log axis equal slopes mean equal percentage moves, which is the comparison being made.
