When the Tax Cuts and Jobs Act (AKA the Trump Tax Cuts) was passed in 2017, common wisdom was that it was bad news for New Jersey’s housing market. The tax law limited the ability for New Jersey homeowners to deduct sales and local taxes from their federal taxes, penalizing homeowners in high-tax states, hitting those with more expensive homes the hardest. This increase in the cost of home ownership was predicted to especially hurt the high end of the housing market.

According to a report by Princeton-based real estate agency Callaway Henderson, the experience of the last year and a half shows that the law has had the effect that was foreseen: “The loss of SALT deductibility has, in fact, slowed real estate markets in high tax states, of which New Jersey certainly is one … buyers have a budget for what they can spend on a home on a monthly basis if carrying costs become too expensive, the sale price is the element most subject to change in order to balance things out.”

The report singled out Princeton, with its abundance of homes priced above $2 million, as a market that is experiencing “pricing recalibration” as seen in the statistic that homes that sold for 21 percent above their assessed tax value last year were now going for 13 percent over.

But how are home prices doing in the rest of Mercer County? U.S. 1 surveyed the most expensive homes currently listed for sale in each municipality.

The kitchen at 324 South Broad Street in Trenton.


Several homes in Trenton currently on sale are listed for more than $300,000, and they are mostly located in the Hiltonia section in the northwest end of the city. Hiltonia, separated from the rest of the city by Cadwalader Park on one side and the Delaware and Raritan Canal on the other, has always had the biggest, most expensive homes in state capital since it was developed in the 1920s.

There is one outlier, however and that is a three-story townhouse located at 324 South Broad Street just down the block from the Mill Hill Saloon, asking $480,000. The listing for the 3,000-square-foot home begins, “Enter into 324 South Broad Street and find the unexpected” and the photos deliver. The heavily renovated 1950 home has floating stairs, a loft, and a garage with an electric car charging station.
