Why buyers look at the Princeton area

For buyers leaving New York, the Princeton area combines three things that are hard to find together: a train station with express service to New York Penn Station in about 55 minutes, nationally known schools and a university town, and open land within a short drive. Mercer County’s towns also sit right across the Delaware River from Bucks County, Pennsylvania, so many buyers compare both sides before choosing.

Karen Langsfeld is licensed in New Jersey and Pennsylvania, so she can show you Princeton on Saturday morning and Yardley that afternoon.

Taxes to plan for


Across the river

Frequently Asked Questions

Which Princeton-area towns are best for commuting to New York?
West Windsor, home of the Princeton Junction station, has the shortest commute, with express trains reaching New York Penn Station in about 55 minutes. Princeton connects to Princeton Junction by the Dinky shuttle. Pennington and the Hopewell Valley are about 20 minutes from Trenton, Hamilton, or Princeton Junction by car, and trade a longer drive for more land and a historic small-town setting.
Is Karen Langsfeld licensed in New Jersey?
Yes. Karen Langsfeld is licensed as a REALTOR® in both New Jersey and Pennsylvania, with Berkshire Hathaway HomeServices Fox & Roach. That lets buyers compare Princeton-area towns with Yardley, Washington Crossing, and New Hope across the Delaware River with one agent, and lets sellers on either side work with the same person.

Mercer County's 2025 average residential tax bill was $9,887, according to the New Jersey Division of Taxation, with much higher averages in Princeton ($23,373) and West Windsor ($16,604).
