The Mercer County Housing Market
The median home price across Mercer County sits near $475,000, but that single number hides a wide spread. Princeton and West Windsor generally price above the county median, while more inland or higher-density submarkets can come in well below it. When I prepare a valuation, I work from closed sales inside your own neighborhood and price tier — that is the only comparison a buyer's appraiser will accept.
Demand is driven by pharma, tech, and university employment, which keeps a steady floor under home values even when interest rates move.
With roughly 385,000 residents and Trenton as the county seat, Mercer County supports a full range of housing: pre-war homes in established downtowns, post-war subdivisions, newer townhouse and condo communities, and a smaller pool of luxury and waterfront or estate properties.
