EXPERTS IN PROPERTY MANAGEMENT
Ready to help you at ANY time of the day... or night
Extra Property Management is headquartered on South Broad Street in Trenton — not in another county, not in another state. We manage single-family rentals, small multifamily buildings, condos, and HOA communities across all of Mercer County, from the row houses of the capital city to the newer townhomes of Robbinsville and the university rentals around Princeton. If you own a rental here and want a manager who already knows the difference between a Trenton rental-registration turnover and a Twin Rivers HOA rule, you are in the right place.
We are the most-reviewed property management firm working out of Mercer County. That review moat matters because Mercer's property-management search results are crowded with out-of-area franchises and directory listings — owners want a local firm they can actually reach.
Full-service residential, HOA & commercial management across Mercer, Middlesex, Somerset, Burlington, Hunterdon & western Monmouth NJ + Bucks County PA.
We run the full landlord workload so you can hold Mercer County rentals as an investment, not a second job. Every service below is handled in-house by our Trenton team.
We market your unit, show it, and screen every applicant — credit, income, rental history, and background — against consistent, fair-housing-compliant criteria. Our leasing agents handle the showings, applications, and lease signing across Mercer County and hand you a qualified, placed tenant. In a county where Trenton, Ewing (TCNJ), and Lawrence (Rider) all pull student and workforce renters, correct screening is what separates a paying tenant from an eviction. This is the core of our tenant placement services in Mercer County NJ.
Tenant screeningRent is due on the first, collected online, and posted to your owner statement automatically. When a tenant misses, we send the notices and start the legal clock the same week rather than letting arrears pile up — the difference between a late payment and a Special Civil Part filing is often how fast the manager moves.
Rent collection servicesTenants report issues through a 24/7 portal; we dispatch our vetted Mercer-area vendors, and you approve anything over your set threshold before a dollar is spent. Older Trenton and Hamilton housing stock needs a manager who knows which plumber actually shows up — we keep those relationships so you don't have to.
We document condition at move-in, run periodic interior/exterior checks, and inspect at move-out against the original report — the paper trail that protects your security-deposit position under New Jersey law. Turnover inspections also catch the small problems before they become the expensive ones.
When a tenancy has to end, we handle notices, coordinate the attorney, and see the case through Mercer's Special Civil Part in Trenton. Because a business-entity landlord must be represented by a New Jersey attorney in landlord-tenant court, doing this alone is rarely an option — more on our county eviction process below.
You get an owner portal with monthly statements, itemized income and expenses, and year-end documents your accountant can use. Out-of-state owners — and Mercer has plenty, especially absentee Trenton landlords — get the same transparency as someone across town. This is the backbone of our landlord services in Mercer County NJ.
Landlord servicesMost Mercer County rentals are long-term, and that is where the steady returns are — but we also handle short-term and Airbnb management in Mercer County NJ where the location and the rules genuinely support it, such as furnished visiting-scholar and relocation stays around Princeton. Short-term rentals live and die on local zoning and HOA restrictions, so before you list, we tell you honestly whether a unit is a good Airbnb candidate or better run as a long-term rental. Where a property qualifies, we handle the listing, guest turnovers, and compliance; where it does not, we will say so rather than sell you a strategy that gets shut down.
Mercer's suburbs are dense with community associations, and boards here need a manager who understands both the buildings and the budgets. We provide HOA management and condo management for Mercer County NJ associations: dues collection and delinquency follow-up, vendor and common-area maintenance, board and annual-meeting support, financials and reserve tracking, and rule enforcement. East Windsor's Twin Rivers — New Jersey's first planned-unit development, opened in 1970 — and Robbinsville's Town Center and Foxmoor communities are exactly the kind of townhome and condo stock we manage. Whether you are a self-managing board looking for relief or an owner in an association that needs professional help, we can quote the scope.
Beyond homes, we handle commercial property management in Mercer County NJ — small retail strips, mixed-use buildings, and office suites, the kind of stock that clusters along Trenton's downtown, Route 1 in Lawrence and West Windsor, and the Route 130 corridor in East Windsor. Commercial owners get lease administration, CAM handling, tenant coordination, and the same monthly reporting our residential owners rely on. The logistics-and-warehouse growth around Robbinsville has added a layer of small commercial and flex space that needs local management, too.
Evictions in Mercer County are filed with the Superior Court of New Jersey, Special Civil Part, at the county courthouse on South Broad Street in Trenton. We manage eviction services in Mercer County NJ end to end: serving the correct notice, filing the complaint, coordinating your New Jersey attorney (required for LLC and corporate landlords), appearing through to judgment, and scheduling the lockout with the county Sheriff's civil-process division if it goes that far. Trenton has among the higher eviction-filing rates in the state, so this is not a rare event here — having a manager who files cleanly and quickly is what keeps a bad tenancy from turning into months of lost rent. For owners, the goal is always to avoid court through good screening and fast collection; when that fails, we already know the process cold.
Mercer County holds roughly 387,000 people across a genuinely mixed rental landscape, and about 38% of the county's occupied homes are rented — higher than most of suburban central New Jersey. The county-wide median gross rent runs around $1,600 a month (2019–2023 Census ACS), but that single number hides how different each town is, which is exactly why a Princeton owner and a Trenton owner need different management.
Property types run the full range — from Trenton's two- and three-family row houses to Robbinsville's newer townhomes to Princeton's estate rentals — so we tailor rental market analysis for Mercer County NJ to your specific town and property rather than quoting a county average.
Mercer landlords answer to two layers of rules. At the state level, New Jersey's Truth-in-Renting Act (N.J.S.A. 46:8-46) requires you to give tenants the DCA Truth-in-Renting statement, security deposits are capped at one and a half months' rent and must be held in a proper account with interest returned within 30 days of move-out, and the Anti-Eviction Act limits removals to specific just causes. Most New Jersey municipalities also require non-owner-occupied rentals to be registered, and several Mercer towns add their own layer — Trenton, for example, requires rental registration and inspection on turnover, while the county's HOA-heavy townships fold in association rules on top. The specifics vary town by town, which is covered on each town page — see Robbinsville for a Town-Center/HOA example. We keep your registrations current, your deposits compliant, and your notices legally correct, so a technical misstep never sinks an otherwise good case.
Most firms that show up for "property management companies in Mercer County NJ" are national franchises or directory pages routing your call somewhere else. We are actually here — a Trenton office, a real local team, and over 330 five-star Google reviews earned in this county. Being the best-reviewed property management company in Mercer County NJ isn't a slogan; it's the thing that lets a skeptical out-of-state owner trust us with a house they've never seen. Our management is a flat, affordable percentage of collected rent with no surprise fees — the best-reviewed firm in the county doesn't have to be the most expensive one. We manage the whole county from one place, which means one point of contact whether your rental is in Trenton, Princeton, or Robbinsville.
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.
Absolutely professional. Everyone at Extra Property Management is competent, friendly, well-informed, and above all always solution-oriented. They deliver what they promise.
Most full-service management in Mercer County runs about 8–10% of collected rent, with a separate tenant-placement fee that typically falls between half and one month's rent. We quote a flat, transparent rate up front with no surprise line items — and we'd rather tell you our property management fees for Mercer County NJ in the first call than bury them. Your exact rate depends on the property type, location, and number of units.
All of them. We manage rentals and associations in Trenton, Hamilton, Ewing, Lawrence, Princeton, West Windsor, East Windsor, Hopewell, Pennington, Robbinsville, and Hightstown — the full county. See the town list below for details on each.
Yes. We serve notices, file with the Special Civil Part in Trenton, coordinate the required New Jersey attorney for LLC and corporate owners, and see the case through judgment and, if necessary, a Sheriff's lockout. Strong screening and fast rent collection keep most of our owners out of court in the first place.
We do. Alongside residential rentals we provide HOA and condo management for Mercer County associations — dues collection, maintenance, board support, financials, and rule enforcement — for townhome and condo communities like those in Robbinsville and East Windsor's Twin Rivers.
That's a large share of our owners. Mercer — Trenton especially — has many absentee and out-of-state landlords. You get an online owner portal, monthly statements, and one local contact, so property management for out-of-state owners in Mercer County NJ works exactly like managing from across town.
