What makes Pennington different
Home Value, By Source

Separately, Mercer County's current median listing price (via Realtor.com data, 2026-06-01) runs $472,500. These cover different geography (city vs. county) and different measures (assessed value vs. active listings), which is why we show both rather than picking one — full source list on our data sources page.
