Best Places to Live in Mercer County NJ: Princeton, Hamilton & Lawrenceville
Mercer County sits at the geographic center of New Jersey, roughly equidistant between New York City and Philadelphia. That position makes it a practical choice for people who commute to either city, work in the pharmaceutical and technology corridor along Route 1, or want suburban life without sacrificing access to urban amenities.
The county ranges from Princeton – one of the most expensive and celebrated small cities in the country – to Hamilton Township, Mercer’s largest municipality and one of its most affordable. Understanding those differences matters before you commit to a neighborhood or a moving date.
Here’s what you need to know about the best places to live in Mercer County NJ in 2026.
Princeton
Princeton consistently ranks as one of the best places to live in New Jersey. It combines the intellectual energy of a major research university with a walkable downtown, excellent public schools, and a strong community identity. Nassau Street is lined with independent restaurants and boutiques. Palmer Square is one of the better-preserved historic commercial districts in the state.
The tradeoff is cost. Princeton is among the most expensive municipalities in New Jersey. Home prices regularly exceed $900,000 for a median single-family home, and rental prices reflect that. Families relocating to Princeton are typically doing so for the school district, Princeton University affiliation, or proximity to pharmaceutical and finance employers along the Route 1 Research Corridor.
Best for: University-connected households, NYC/Philadelphia commuters, professionals in R&D and biotech.
Transit: NJ Transit Princeton Branch (the “Dinky”) connects to Princeton Junction on the Northeast Corridor, with direct service to New York Penn Station.
Moving note: Downtown streets near Nassau Street and the university campus are narrow. Parking permits are required near campus on move days. Coordinate with the borough parking authority in advance if your home is in the downtown core.
Hamilton Township
Hamilton is Mercer County’s largest municipality at over 90,000 residents and its most varied. The township spans a wide range of neighborhoods – from quiet residential streets near Grounds for Sculpture to more active commercial corridors along Route 1 and Route 130. It doesn’t have Princeton’s prestige, but it offers something the rest of the county often can’t: genuine affordability combined with excellent access.
Hamilton Station on the Northeast Corridor is one of the best-kept commuting secrets in central New Jersey. Amtrak stops here, making Philadelphia about an hour away and Penn Station under 90 minutes. The township also has more than 60 parks and a housing stock that ranges from modest ranch homes to larger colonials at prices well below the county average.
Best for: Families, first-time buyers, commuters who want Northeast Corridor access without Princeton pricing.
Transit: Hamilton Station serves both NJ Transit and Amtrak – one of the most convenient transit options in Mercer County.
Moving note: Most Hamilton properties are single-family with driveways – good truck access, no COI typically required. This is straightforward suburban NJ moving territory.
Lawrenceville (Lawrence Township)
Lawrenceville is the residential and commercial center of Lawrence Township, positioned between Princeton to the south and Trenton to the north. It has a quieter, more established suburban feel than Hamilton and sits close enough to Princeton to share some of its character without the full price tag.
The Route 1 corridor through Lawrence Township is a major employment zone – Novo Nordisk, Bristol Myers Squibb, and other major pharmaceutical firms have facilities nearby. Residents often work along Route 1 and want walkable neighborhoods on weekends without paying Princeton prices.
Best for: Route 1 corridor employees, families who want Princeton proximity at lower cost.
Moving note: Some newer apartment complexes near Route 1 require a COI from your moving crew. Check with your building management before move day.
West Windsor
West Windsor is one of the most sought-after school districts in New Jersey – West Windsor-Plainsboro Regional is consistently ranked among the top ten districts statewide. Princeton Junction station sits in West Windsor and offers direct NJ Transit service to Penn Station. Housing is more expensive than Hamilton and Lawrenceville but less expensive than Princeton Borough. Families relocating specifically for the schools frequently land here.
Robbinsville
Robbinsville has grown from a largely rural township into a planned mixed-use community. The Town Center development has a walkable commercial core surrounded by townhomes and single-family neighborhoods. Good schools, newer construction, and a commuter-friendly location near Route 130 and I-195 make it a strong option for families.
Hopewell Township
Hopewell Township offers the most rural feel in Mercer County – large lots, horse properties, and open farmland. It sits immediately north of Princeton and shares some of its population profile while offering substantially more land for the money. The tradeoff is car dependency; there is no meaningful public transit and most errands require driving.
Pennington
Pennington Borough is a small, historic community with roughly 2,000 residents, a charming Main Street, and a tight-knit community feel that’s hard to find in larger municipalities. Taxes are high relative to the housing stock, but residents consistently cite the walkability and neighborhood character as reasons they stay. For someone moving out of an urban environment and wanting a genuine small-town experience within commuting range of Princeton, Pennington deserves consideration.
What to Know Before Moving in Mercer County
Mercer County is predominantly a suburban county with single-family home stock – which means most moves involve driveways, stairs, and full-house unloads rather than elevator reservations. That said, there are important exceptions:
- Managed apartment buildings along the Route 1 corridor in Lawrence Township and West Windsor may require a Certificate of Insurance from your moving crew. Ask your building management at least one week before your move.
- Princeton Borough has narrow streets and limited truck parking near campus and Nassau Street. Confirm loading zone availability with the borough parking authority if your home is near downtown.
- Hamilton Township moves are typically the most logistically straightforward – wide streets, long driveways, minimal building restrictions.
- Route 1 through Mercer County experiences heavy congestion during morning and evening rush hours. A move that starts at 8am will encounter very different conditions than one that starts at noon.
