Homes for Sale in Union, NJ

Why buyers and sellers choose Union.

Union Township is a 9-square-mile Union County township of roughly 58,000 residents — and one of the most reliable, family-oriented residential markets in the broader Newark/Union County corridor. Anchored by Kean University, the Union NJ Transit station on the Raritan Valley Line, and the always-busy Route 22 commercial corridor, Union combines suburban residential character with genuine commercial depth and easy access to NYC, Newark, and the broader North Jersey region. The housing stock is largely well-kept colonials, capes, ranches, and split-levels in established neighborhoods that buyers and sellers have known for generations.

Our Union office at 1915 Morris Avenue sits in the township and works the local market continuously — buyers, sellers, investors, first-time homeowners, and the multi-family inventory that's increasingly common as Union's housing stock matures.

Union NJ homes for sale

Union Township's housing stock breaks down into three broad tiers. Entry-level Union NJ homes ($450K to $575K) include starter capes, ranches, and modest colonials in the older sections and around the Kean University neighborhood, popular with first-time buyers and investors. Mid-market Union homes ($575K to $750K) are the volume anchor, well-maintained colonials, split-levels, and expanded capes across Battle Hill, Putnam Manor, and the streets between Morris Avenue and the Parkway. Higher-end Union homes ($750K to $900K+) include larger updated colonials, custom-built homes, and select luxury properties in Battle Hill and Larchmont. Union also has a healthy multi-family segment (duplex, two-family, three-family homes) that trades in the $550K to $850K+ range depending on income and condition, ideal for investors and house-hackers.

Union NJ condos and townhomes

Union's condo and townhome segment is smaller than the single-family market but has strengthened in 2026. June 2026 townhouse/condo activity closed 5 sales at a median of $535,000, up 18.2% year-over-year, with 27 days on market and 101.9% of list. Inventory is at 13 active listings, giving buyers meaningful choice in the segment. Union condos are a favorite for downsizers moving out of larger single-family homes, young professionals working in Newark or NYC who want maintenance-free ownership, and buyers who want to stay in Union but don't need or want the responsibilities of a house.

Union neighborhoods

The Battle Hill neighborhood (around the Battle Hill Monument area) is one of Union's most-requested sections, slightly elevated, established, and family-oriented. The streets around Kean University attract a mix of long-time residents, faculty, and student-rental investors. The Putnam Manor and Larchmont areas offer some of the larger established homes with premium finishes and lot sizes. The Morris Avenue corridor around our office mixes residential streets with Union's commercial core. Each neighborhood has its own pricing rhythm; working with a Union NJ realtor who knows the block-level dynamics is critical to getting a fair value on either side of the transaction.

Schools — Township of Union Public Schools

Township of Union Public Schools is a K-12 district serving the entire township. The district operates multiple elementary schools, three middle schools (Burnet Middle School, Kawameeh Middle School, Jefferson School), and Union High School. Union High is one of the larger high schools in the area with a comprehensive academic and athletic program. The school system's broad reach across the township means feeder patterns are an important consideration when evaluating a specific home.

Commute & access

Union's commute options are strong. The Union NJ Transit station sits in town with Raritan Valley Line service connecting to Newark and Manhattan (with transfer). The Garden State Parkway runs along Union's eastern edge with quick access north (to Bergen County) and south. Route 22 cuts through the township east-west. I-78 is minutes south. Drive time to Midtown Manhattan averages 35–55 minutes depending on traffic and route choice — significantly faster than most of our Butler/Kinnelon coverage area, reflecting Union's closer proximity to the city.

Union home prices, June 2026

Union Township posted one of Union County's strongest June 2026 markets. Single-family closings hit 43 transactions, up 48.3% year-over-year, and the median sale price landed at $609,000, up 1.5% YoY. Homes averaged 22 days on market and sold at 104.1% of list price, meaning most quality Union listings are receiving over-asking offers. Active inventory is at 57 listings, a 1.8-month supply, down 17.4% from a year ago. That combination of surging demand and tightening supply is what drives Union's competitive dynamics right now.

Bottom line for buyers: Union is one of the busiest Union County markets and you should expect to compete. Come with pre-approval and be ready to move fast on the right property. Bottom line for sellers: your Union home is likely worth more than you think, and the 104.1% list-to-sale ratio means pricing correctly at launch reliably produces multiple offers.
