We Buy Houses in Hamilton Township, NJ

Hamilton Township at a Glance

Hamilton is a township of owners: owners occupy close to 72% of its homes, and in the Census Bureau's five-year survey 92.3% of residents gave the same address as twelve months before. People stay. That is also why so many of the calls from Hamilton come from long-term owners, or their children, deciding what to do with a house whose last real renovation is a distant memory.

• 94,157residents estimated for July 2025 (92,297 in the 2020 census)
• 71.6%owner-occupied homes, per the 2020–2024 ACS
• $335,500median value owners report for their homes (ACS 2020–2024)

Figures from U.S. Census Bureau QuickFacts for Hamilton township, Mercer County. Median value is a survey answer from owners, not a recorded sale price.

A township-wide median hides a lot. A kitchen untouched since the 1970s, a wet basement, an old oil tank or a roof that is past saving all move the number for one house, and we price each one after a single walk-through. You get one written figure, with nothing taken off later for an inspection.

The Change of Occupancy Inspection

Hamilton is one of the New Jersey towns that inspects a home whenever its occupants change. Before anyone moves in, the Office of Housing Inspections must issue a certificate of approval stating that the house meets township ordinances. The application can be filed through the township's online change of occupancy portal, which does not require an account, or on paper at the municipal building on Greenwood Avenue. Only the owner, the owner's real estate agent, attorney or someone holding power of attorney may apply.

A few details surprise sellers:

• The $200 fee covers the first inspection and one re-inspection. Each visit after that costs $100, and if an inspector arrives and no adult is there to open the door, the township keeps the fee and charges $75 to reschedule.
• The inspection stays good for nine months from the application date. If the house has not sold by then, the process starts over.
• The certificate itself is written in the buyer's name and lasts 90 days once issued.
• Inspectors want smoke detection on each floor, the basement too, plus a finished attic if there is one, and CO detection no farther than ten feet from any bedroom door. Hard-wired and battery units both pass.
• Every major violation has to be fixed. A buyer may sign for minor items, but any exterior work then has to be finished within nine months.

The township is clear that the certificate is needed to occupy the house, not to close on it, and occupying includes moving belongings in. In practice, a buyer's lender often will not close without it. We do not need one to close and are not borrowing, so a sale to us can settle before the inspection happens; we apply as the new owner, take the violation list and do the repairs ourselves before anyone moves in.

Two cheaper routes exist. Selling to the tenants who already live in the house, or to a son or daughter who already lives there, calls for only a $100 smoke and carbon monoxide inspection. And when a landlord sells to another landlord with the same tenants staying, the seller passes along the current certificate and the buyer must register as a landlord before closing.

Taxes, Sewer Charges and the Tax Sale

Hamilton's Division of Revenue Collection bills both property taxes and the township's sewer fee. Tax installments are due four times a year: February 1 opens the year, followed by May, August and November, each on the first. Sewer is billed separately, due March 1 and October 1. The office notes that every outstanding tax and municipal fee has to be paid before it will process applications, so arrears can hold up paperwork as well as a closing.

On the state's 2025 figures, the township's rate came to 3.708 on assessed value, or 2.434 once adjusted to market value, a little higher than Lawrence's and well below Trenton's. Charges still unpaid late in the year go to the township tax sale, which Hamilton now runs as an online auction; its 2025 sale covered 2025 and earlier taxes, sewer and other municipal charges, and once a property is on that list the collector takes only cash, a certified check or a money order. Where a lien certificate is already outstanding, our settlement agent gets the precise redemption amount in writing from Greenwood Avenue and clears it out of the price. For the mechanics of redemption, and the equity protection owners gained in 2024, read the tax lien guide.

Water and Sewer Service

Wastewater from most of Hamilton runs to the township's own Department of Water Pollution Control on Hobson Avenue, a regional plant that serves more than 100,000 people in three municipalities through 350 miles of sewer line and 27 pumping stations. Drinking water is a different story. Trenton Water Works supplies parts of the township, and in the townships it serves, an unpaid balance stays with the account holder rather than becoming a charge on the property. If a different company sends your water bill, that is the one we ask for the final reading. We order that reading and the sewer payoff once a closing date is set.

Renting Out a Hamilton House

Landlords in Hamilton need a township landlord license and a registration for each rental unit. An owner who lives outside Mercer County must name a managing agent who lives in the county and can accept notices and legal papers. Under a 2022 state law, rental owners also file a certificate of liability insurance with the township every year, and any pre-1978 rental now has to be certified lead-safe or lead-free (the township's deadline was July 2025) before a rental change of occupancy application will be accepted.

If those filings have fallen behind, we can still buy. Tenants stay under their leases, because selling is not on the Anti-Eviction Act's short list of reasons to end a tenancy; deposits, plus whatever interest has built up, are handed over to us on closing day. When the tenants themselves would like to buy, remember the township's reduced $100 inspection for that case. Landlords will find more detail in our guide to selling a rental.

Vacant Houses and Homes in Foreclosure

Under Hamilton's vacant-property ordinance, registration is due 90 days after a house empties out; someone who acquires a house that is already empty gets 30 days from taking title. A separate foreclosure registry puts a duty on the lender: a lender that files a foreclosure has ten days to enter the property in that registry, paying $500 for an occupied house and another $2,000 if the house is empty. Those rules explain why an empty house in foreclosure tends to draw code notices quickly.

A foreclosure filing does not stop you from selling. You can contract with us up until the sheriff's auction in Trenton, and state law lets you back out of that contract for ten business days; we schedule settlement after that window closes. The foreclosure guide covers the full timeline.

Flood Insurance in Hamilton

Parts of Hamilton lie in mapped flood hazard areas. Through FEMA's Community Rating System the township has earned discounts on flood insurance, 15% for policies in Special Flood Hazard Areas and up to 5% for some lower-risk properties, and its floodplain page says it is the only Mercer town that currently qualifies. Every seller in New Jersey must complete the state flood risk disclosure, covering the property's flood zone, any flooding you know of and claims you have filed. Answer it as it is. A basement that has taken water is a repair we price, not a reason to walk away.
