North Plainfield, NJ real estate: the numbers, explained.

Home values in North Plainfield

Zillow Home Value Index (all homes, middle tier, smoothed, seasonally adjusted) for the Zillow region “North Plainfield”, September 30 of each year. Source: Zillow Research.

Zillow’s Home Value Index for North Plainfield was $494,213 as of September 30, 2026, up 0.1% from a year earlier and up 35% over five years. Over ten years the index rose 108.9%. ZHVI models a typical home value. It isn’t the price of any specific house.

The NJ Division of Taxation’s 2026 Average Residential Statistics show an average residential sale price of $454,577 across 154 sales used in that report. Averages can be pulled up or down by a few sales, which is one reason it can differ from Zillow’s index.

The Census Bureau’s survey puts the median value of owner-occupied homes, as estimated by owners, at $374,700 (2020–2024 average), compared with a Somerset County town median of $547,600.

North Plainfield property taxes

North Plainfield’s 2025 general tax rate was 4.543 per $100 of assessed value, and its effective tax rate was 2.595%, higher than the Somerset County town median of 2.030% and higher than the statewide municipal median of 2.141%. That ranks it #20 lowest of 21 Somerset County municipalities by effective rate. The average residential tax bill was $10,245 on an average assessment of $225,507 across 4,952 residential properties.

Applied to the typical home value of $494,213, the effective rate implies roughly $12,825 a year ($1,069 a month) in property tax. The Division publishes the effective rate for comparing towns, not for computing a specific bill, so use it as a ballpark.

With estimated property tax that’s about $3,747, before insurance, any HOA fee and utilities.

Schools

I don’t republish unofficial school scores. For North Plainfield, start with the New Jersey Department of Education’s School Performance Reports, then confirm the exact school assignment for any address with the district, since some NJ towns send students to regional or neighboring high schools.

Downtown, food and things to do

The best way to judge North Plainfield’s restaurants, parks and weekend life is in person. Visit on a weeknight and a Saturday morning, check the town recreation calendar and walk the blocks you’d live on. My town scouting checklist shows what to look for.

My take for buyers, sellers and renters

• Renters: with 46.7% of homes renter-occupied, North Plainfield has a deep rental market. Line up documents before touring. The move-in calculator shows the cash you’ll need.
• Buyers: taxes run above the county median, so budget on the tax bill, not just the price. Ask for the current bill on every listing.
• Sellers: values are up 35% in five years, so many owners have significant equity. See your number in the seller net sheet.
