Local Market Data
Middlesex County Apartment Market
Figures gathered October 2026 from public market data.
If you plan to sell commercial property in Middlesex County, NJ, start with the renter base. Middlesex County counts 111,894 renter households, a 36.4% share of its 307,782 occupied homes, per the Census Bureau's 2020-2024 American Community Survey. New Brunswick alone holds 12,322 renter households at a 78.6% renter share, and Edison adds another 15,020 renter households of its own.
Apartment buildings carry a real share of that demand. Some 76,341 Middlesex County housing units, 24.0% of the stock, sit in buildings with five or more units. Median gross rent reached $1,871, up 27.4% from the 2015-2019 survey. Rental vacancy stands at just 2.4%, so buyers price lease-up risk differently here than in looser markets. Rents and renter shares still vary widely from one Middlesex County city to the next.

South Plainfield sits at the other end, with a 14.1% renter share and the highest rent in the table at $2,107. Vacancy ranges from 1.5% in Carteret to 5.8% in South Plainfield, a gap Middlesex County buyers weigh alongside rent levels.
Property taxes and assessment in Middlesex County
Middlesex County does not set one countywide tax rate; each municipality within Middlesex County adopts its own general tax rate, and New Jersey assesses real property as of October 1 of the pretax year. A parcel's taxable value equals its assessed value divided by the municipal average ratio, so a ratio below 100% means assessed value understates true market value.
Owners of apartment buildings in Middlesex County can appeal an assessment to the county board of taxation by April 1, or within 45 days of a bulk mailing of notices if that date is later, per the Division of Taxation's assessment calendar. Assessments above $1,000,000 may go directly to the state Tax Court, with a $150 filing fee. New Jersey assessments generally carry over year to year rather than resetting at every sale, so a Middlesex County seller's current bill is not necessarily what a buyer inherits.
What this means if you sell in Middlesex County
When you sell commercial property in Middlesex County, NJ, you sell into one of the tighter rental markets in the state. Renters hold 36.4% of households, and rental vacancy runs just 2.4%, so buyers underwrite strong occupancy as a given rather than a risk. New Brunswick and Edison offer the deepest renter pools in Middlesex County, while South Plainfield's small renter base trades on income growth instead of unit count.
New Jersey carries no statewide rent control; municipalities decide it themselves, so a Middlesex County buyer checks each city's ordinances rather than assuming one rule applies countywide. Security deposits are capped at 1.5 times monthly rent under N.J.S.A. 46:8-19, and on a sale the seller must turn deposits plus accrued interest over to the buyer at closing.
As a multifamily buyer active in Middlesex County, we review 5+ unit buildings from New Brunswick to Woodbridge as they stand today. Send a current rent roll, a T-12 and your latest tax bill, and we will price the building on those numbers.

Middlesex County Seller FAQ
What should I know about rent control before I sell commercial property in Middlesex County, NJ?
New Jersey has no statewide rent control law, per the Department of Community Affairs.

Rental vacancy in Middlesex County was 2.4% in the Census Bureau's 2020-2024 American Community Survey, among the tightest readings tracked here.
