How to read these numbers
Velocity vs. level
A market with 25% one-year appreciation is moving fast — but a market with steady 6% over ten years has compounded much further. Use 10Y as the long-run signal, 1Y as the momentum signal.
Mean-reversion risk
Markets that posted huge 1Y and 3Y gains often cool over the next cycle. Compare 1Y to 5Y: if 1Y is far above 5Y, the trend is accelerating; if far below, it is decelerating — often the more important signal.
Sample sanity
We require a minimum current median price (default $50K) to filter out tiny ZIPs with noisy data. Raise that threshold for serious investment markets; lower it to find emerging niches. Source: public record.
