Branchburg, NJ real estate: the numbers, explained.

Home values in Branchburg

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

Zillow’s Home Value Index for Branchburg Township was $722,739 as of September 30, 2026, up 2.7% from a year earlier and up 30% over five years. Over ten years the index rose 58.6%. 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 $670,604 across 46 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 $610,800 (2020–2024 average), compared with a Somerset County town median of $547,600.

Branchburg property taxes

Branchburg’s 2025 general tax rate was 1.709 per $100 of assessed value, and its effective tax rate was 1.737%, lower than the Somerset County town median of 2.030% and lower than the statewide municipal median of 2.141%. That ranks it #5 lowest of 21 Somerset County municipalities by effective rate. The average residential tax bill was $10,654 on an average assessment of $623,379 across 4,986 residential properties.

Applied to the typical home value of $722,739, the effective rate implies roughly $12,554 a year ($1,046 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 $4,963, before insurance, any HOA fee and utilities. For comparison, the Census median gross rent in Branchburg is $2,268.

Schools

I don’t republish unofficial school scores. For Branchburg, 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 Branchburg’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

• Buyers: a below-county-median effective tax rate stretches your budget further here than in many Somerset towns. Compare with the town comparison tool.
• Sellers: values are up 30% in five years, so many owners have significant equity. See your number in the seller net sheet.
