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 Union.

METRO · Charlotte, NC
No mix-shift history for this area. no geography from this ZIP up to metro has 8+ quarters of 10+ recorded arms-length sales across at least 4 price tiers. Trends are drawn only from recorded transactions; the last-sale snapshot above cannot carry a time series, because a property that sold twice keeps only its latest sale — which drags the history upward through the tiers and would invent the very mix shift this section exists to test for.
