Monroe, NJ real estate: the numbers, explained.

Home values in Monroe

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

Zillow’s Home Value Index for Monroe Township was $625,535 as of September 30, 2026, up 1.9% from a year earlier and up 32.9% over five years. Over ten years the index rose 69%. 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 $600,926 across 622 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 $540,900 (2020–2024 average), compared with a Middlesex County town median of $446,400.

Monroe property taxes

Monroe’s 2025 general tax rate was 2.74 per $100 of assessed value, and its effective tax rate was 1.557%, lower than the Middlesex County town median of 2.098% and lower than the statewide municipal median of 2.141%. That ranks it #2 lowest of 25 Middlesex County municipalities by effective rate. The average residential tax bill was $9,229 on an average assessment of $336,808 across 21,414 residential properties.

Applied to the typical home value of $625,535, the effective rate implies roughly $9,740 a year ($812 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 $625,535 home with 20% down ($125,107) 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 $3,390 a month. With estimated property tax that’s about $4,202, before insurance, any HOA fee and utilities. For comparison, the Census median gross rent in Monroe is $2,031.

Schools

I don’t republish unofficial school scores. For Monroe, 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 Monroe’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 Middlesex towns. Compare with the town comparison tool.
• Sellers: values are up 32.9% in five years, so many owners have significant equity. See your number in the seller net sheet.
