EXPERTS IN PROPERTY MANAGEMENT
Ready to help you at ANY time of the day... or night
Extra Property Management is a full-service property management company working for rental owners across Hamilton Township, the largest municipality in Mercer County. Our office sits at 354 S Broad St in Trenton, directly on Hamilton's western border — close enough to walk a vacant unit at Society Hill, meet a contractor in Mercerville, or file a Certificate of Approval the same day. We have earned a 4.8-star rating across 253 Google reviews doing the unglamorous work well: placing screened tenants, collecting rent on time, and keeping owners informed.
Full-service residential, HOA & commercial management across Mercer, Middlesex, Somerset, Burlington, Hunterdon & western Monmouth NJ + Bucks County PA.
Whether you own a Cape Cod in Mercerville, a Society Hill condo, or a small portfolio of two-family homes near White Horse, we handle the day-to-day so you don't have to. Our residential property management in Hamilton Township covers the full cycle from vacancy to renewal — and we manage HOA-governed condos, single-family rentals, and small commercial buildings alike.
Acting as your leasing agent, we market your unit across the major rental portals, show it, and run full tenant screening on every applicant — credit, income verification, eviction history, and prior-landlord references. Commuters using Hamilton Station on the Northeast Corridor and staff at RWJ University Hospital Hamilton keep qualified applicant demand steady, so our tenant placement services can hold out for a renter who pays and stays.
Tenant screening processTenants pay through an online portal with automatic reminders and late-fee enforcement, and we deposit your net proceeds by direct transfer with a clear monthly statement. If a payment slips, our rent collection services act on it immediately rather than letting arrears build into a bigger problem. It's the part of the job most owners are relieved to hand off.
Rent collection servicesMuch of Hamilton's housing is postwar — Cape Cods, ranches, and split-levels in Mercerville, Hamilton Square, and Yardville — and older homes need attentive upkeep. We coordinate repairs through vetted local vendors, hold to a spending threshold you approve in advance, and give tenants a 24/7 way to report issues so small problems get fixed before they become expensive ones.
We document move-in and move-out condition with photos, run periodic interior and exterior checks, and coordinate the township's Housing Inspection process — the inspection tied to Hamilton's landlord license and the Certificate of Approval required before any change in occupancy. Consistent inspections protect your security-deposit position and catch lease violations early.
If a tenancy goes wrong, Hamilton eviction cases are filed with the Special Civil Part at the Mercer County Civil Courthouse in Trenton, and New Jersey's Anti-Eviction Act limits removals to specific just causes. We manage the process end to end — proper notice, filing, and court coordination — and because NJ requires an attorney for LLC-owned rentals, we work with owners' counsel so nothing stalls.
Eviction servicesYou get itemized monthly statements, year-end summaries built for your accountant, and on-demand access to every invoice and lease document through the owner portal. For property management for out of state owners — and Hamilton's train-station access draws New York and Philadelphia investors treating it as investment property — that transparency is the difference between owning a rental and worrying about one.
Hamilton is unusually association-dense: Society Hill at Hamilton II, Kings Gate, the Woodlands, and 55+ communities like Traditions at Hamilton Crossing all run on association governance. We provide HOA and condo management companies-grade service — dues collection, vendor and common-area oversight, budget and reserve support, and board reporting — and we manage individual condo, townhome, and single-family rentals inside these communities, plus small commercial property management for Hamilton's storefront and mixed-use owners.

Hamilton is Mercer County's largest municipality — roughly 38,900 housing units and a median household income near $99,700 — with a real, mixed rental market rather than a heavy-tenant urban core. Roughly one-third to just under 40% of households rent, so owner-occupancy still dominates, and that balance produces stable, longer-term tenants. Median gross rent sits around $1,609 a month, while newer two-bedroom condos and apartments in communities like Society Hill commonly ask well above that. A proper rental market analysis for Hamilton has to account for that spread between older-stock rents and newer-condo asking prices.
Demand comes from three anchors: Hamilton Station on NJ Transit's Northeast Corridor Line — one of the busiest in the system, with a sub-90-minute ride to New York Penn Station — the healthcare sector led by RWJ University Hospital Hamilton, the township's largest single employer, and proximity to Trenton state-government and the Princeton/Route 1 corridor. One thing this market does not support is nightly rentals: Hamilton's Chapter 254 ordinance effectively bans short-term/transient rentals in residential zones, with fines up to $2,000, so there is no viable Airbnb management market here. Practically, almost all of our work — and any short term rental management inquiry we field — converts to standard 12-month leasing, which is exactly what long-term property management is built for.
Hamilton runs one of the more involved landlord programs in Mercer County. Under the township's Housing Standards ordinance, every residential rental must obtain a Landlord License and register through the Housing Inspection & Landlord Compliance Office; registration carries a $50 fee covering an inspection plus one re-inspection on a five-year cycle. A Certificate of Approval from Housing Inspections is required before any change of tenant or owner and is valid 90 days. Out-of-county owners must designate a Managing Agent residing in Mercer County to accept notices and service of process — a role a professional manager is built to fill. Since November 2022, owners must also carry and annually register a Certificate of Insurance with the township, and any pre-1978 rental needs NJ lead-paint certification.
On top of the local rule, New Jersey's statewide obligations apply: the Truth-in-Renting Act (give qualifying tenants the DCA statement), mandatory landlord registration under N.J.S.A. 46:8-27, the security-deposit law (maximum one and one-half months' rent, held with annual interest accounting), and the Anti-Eviction Act's just-cause standard. Limited legacy rent control survives only for pre-September-2002 tenants in 4+-unit buildings. We handle the Landlord License and Certificate of Approval, the insurance and lead filings, the Managing-Agent designation, and the tenant disclosures — missing any one of them is avoidable exposure a manager exists to prevent. Local-rule questions go to the Hamilton Housing Dept. at 609-890-3665.
Search "property management companies in Hamilton NJ" today and you'll find a couple of entrenched managers and a lot of statewide firms that cover Hamilton from a distance. We take the opposite approach: a genuinely local team, a Trenton office that sits right on Hamilton's western border, and a 4.8-star reputation built on 253 real Google reviews — the largest, most current review moat of any manager working this market. For a township this large, this varied in housing, and this HOA-heavy, that combination of local presence and proven service is exactly what an owner should be hiring for.
I had a wonderful experience renting my home through Extra Property Management. The whole process was smooth, professional, and stress-free. The team was always responsive, helpful, and made everything easy. Highly recommend!
I had a few properties that became too much for me to handle on my own, but Extra Property Management did an amazing job. They helped me with everything, keeping track of the details, and taking care of my tenants with respect.
Great team. They have good properties, all in good condition, and they're very fast and efficient with their work. I can't wait to move into my new place. Thank you Extra Property Management.
Most full-service property managers in the Hamilton and greater Mercer County market charge between 8% and 10% of collected rent for ongoing management, plus a one-time tenant-placement fee that typically runs from half a month to a full month's rent. We publish our property management fees up front in a free rental analysis so you can compare honestly rather than guessing — affordable, flat-rate management with no surprise line items.
"Best" comes down to local knowledge, responsiveness, and a track record you can verify. Extra Property Management holds a 4.8-star rating across 253 Google reviews, works Hamilton from a Trenton office right on the township border, and handles residential, single family, condo, and commercial property management along with the HOA communities Hamilton is known for. We'd rather earn your business with a straight rental analysis than a sales pitch.
Yes. Hamilton is one of the most association-dense towns in Mercer County, so we work with HOA and condo management companies-style boards — dues collection, vendor oversight, budgeting, and board reporting — and we manage individual condo and townhome rentals in communities like Society Hill, Kings Gate, and Traditions at Hamilton Crossing. Owners renting units there also have to follow their association's leasing rules, which we track for you.
We do. Hamilton eviction cases are filed with the Mercer County Special Civil Part at the Civil Courthouse in Trenton under New Jersey's Anti-Eviction Act. We manage notice, filing, and court coordination from start to finish — and because NJ requires a licensed attorney for LLC-owned rentals, we coordinate with your counsel. Our upfront tenant screening is built to keep you out of that process in the first place.
In practice, no. Hamilton's Chapter 254 ordinance prohibits short-term and transient rentals in residential zones, with fines up to $2,000 per offense, and the township enforces it. That means Airbnb-style management isn't a viable strategy here — the market is standard 12-month leasing. We focus on long-term property management, which produces steadier income and far less regulatory risk anyway.
Regularly. Hamilton Station's Northeast Corridor access draws investors from New York and Philadelphia, and Hamilton actually requires out-of-county owners to name a Mercer County Managing Agent. We fill that role, and our owner portal, monthly statements, and local hands-on team mean an out-of-state owner never has to fly in — we handle showings, maintenance, the Landlord License, and everything in between.
