Milltown, NJ real estate: the numbers, explained.

Home values in Milltown

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

Zillow’s Home Value Index for Milltown was $610,257 as of September 30, 2026, up 6.8% from a year earlier and up 42.9% over five years. Over ten years the index rose 82.3%. 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 $535,303 across 36 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 $458,800 (2020–2024 average), compared with a Middlesex County town median of $446,400.

Milltown property taxes

Milltown’s 2025 general tax rate was 6.951 per $100 of assessed value, and its effective tax rate was 2.5%, higher than the Middlesex County town median of 2.098% and higher than the statewide municipal median of 2.141%. That ranks it #23 lowest of 25 Middlesex County municipalities by effective rate. The average residential tax bill was $11,424 on an average assessment of $164,350 across 2,384 residential properties.

Applied to the typical home value of $610,257, the effective rate implies roughly $15,256 a year ($1,271 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.

What it costs to own vs. rent

For a $610,257 home with 20% down ($122,051) and a 30-year fixed loan at 7.18%, Freddie Mac’s national average for the week of November 5, 2026, principal and interest come to about $3,307 a month. With estimated property tax that’s about $4,579, before insurance, any HOA fee and utilities. For comparison, the Census median gross rent in Milltown is $1,204.

The median home in Milltown was built in 1963. Much of the housing predates 1978, so buyers should plan for older-home checks: lead-based paint disclosure, an oil-tank sweep if the house ever had oil heat, knob-and-tube or older electrical, galvanized plumbing, and a sewer-line scope. See the NJ inspection checklist.

Schools

I don’t republish unofficial school scores. For Milltown, 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. See how to research NJ schools.

Downtown, food and things to do

The best way to judge Milltown’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: 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 42.9% in five years, so many owners have significant equity. See your number in the seller net sheet.
• Low turnover: about 36 residential sales were in the state’s 2026 report, so good listings can be scarce. Set alerts and be ready to act.
