Philadelphia ZIP Code Trend Board

Weekly Philadelphia ZIP code comp momentum — see which ZIPs are rising, stable, or cooling based on recent strong comparable sales.

Weekly Philadelphia ZIP-level comp momentum, built from recent strong recorded sales — see which ZIPs are heating up, cooling, or stable.

How ZIP momentum is calculated

Every Friday, PhillyCompPro re-scores 19 core Philadelphia ZIP codes based on the previous seven days of recorded arms-length sales. A ZIP is flagged "rising" when its weekly median price-per-square-foot moves up at least three percent above the trailing 13-week median on a comp count of at least eight qualifying sales. "Cooling" flips the same thresholds in the other direction. Everything else is "stable."

The ZIP Trend Board ranks the rising and cooling lists, surfaces the biggest weekly mover, and links into a per-ZIP detail page with the underlying comps.

Why a weekly cadence matters for investors

Philadelphia ZIPs can shift fast, especially in active wholesale corridors like 19121, 19132, and 19134. A monthly statistic smooths over week-to-week reality and hides the inflection that lets an investor lead the curve instead of chasing it. The weekly cadence is the shortest reliable signal that still has enough comp volume per ZIP to be meaningful.

Coverage

The trend board covers the 19 ZIP codes where PhillyCompPro sees enough weekly recorded-sale volume for a reliable momentum signal: 19104, 19119, 19121, 19122, 19123, 19125, 19127, 19128, 19130, 19132, 19133, 19134, 19139, 19143, 19144, 19145, 19146, 19147, and 19148. Each ZIP has its own detail page with the full comp list.

Frequently asked questions

Why are some Philadelphia ZIPs not on the board?

Only ZIPs with at least eight qualifying weekly arms-length sales are scored. ZIPs with thin weekly volume are excluded to keep the momentum signal reliable.
