Your Guide to Mountainside, NJ: A Local Expert’s View

As a residential real estate expert in Union County, I can tell you there’s a unique kind of magic in Mountainside. This isn’t just a town; it’s a serene, beautiful escape nestled on the slopes of the Watchung Mountains. For my clients, Mountainside offers the best of both worlds: the peace and tranquility of a true suburban retreat with the undeniable convenience of Union County’s prime location.

Here’s a look at what I’m seeing on the ground in the Mountainside real estate market.

The State of Our Market: High Value, Extremely Low Inventory

The market here is a testament to the town’s desirability. As of today, September 5, 2025, we have an exceptionally limited number of properties available.

• Extremely low inventory: I’m currently tracking just six homes on the market in Mountainside. This scarcity is a major factor driving the market’s intensity. For a town of this caliber, a handful of listings means intense competition among buyers for every available property.
• Prices are climbing: The median sale price for homes in Mountainside has seen a significant increase, with properties often selling for over their list price. It’s not uncommon to see a home go for 10% or more over its asking price when multiple buyers are vying for the same property.
• Homes sell quickly: When a desirable home comes on the market, it doesn’t stay there for long. On average, homes in Mountainside are selling in under 20 days. My job is to ensure my clients are prepared to act swiftly and decisively when a listing that fits their criteria becomes available.

For my selling clients, this is an excellent time to capitalize on your home’s value. The demand is there, and with a strategic pricing and marketing plan, we can attract multiple competitive offers. For my buyers, the key is preparation and partnership. We must be ready to move quickly with a strong, clean offer.

What Makes Mountainside So Desirable? It’s All About Lifestyle.

The strength of our market isn’t just about the numbers; it’s about the lifestyle that Mountainside offers. I often tell my clients that this is a town for those who value nature, community, and peace.

• A Nature Lover’s Paradise: Living in Mountainside means having direct access to the Watchung Reservation, a 2,000-acre wooded park that feels a world away. My own family and I often enjoy the scenic trails, and it’s a huge draw for anyone who loves hiking, horseback riding, or simply escaping into nature.
• Top-Tier Schools: The Mountainside School District is a huge draw for families. It’s a highly regarded K-8 district, and the community’s commitment to education is evident in the excellent student-to-teacher ratio and academic performance. The high school sending-receiving relationship with nearby Berkeley Heights ensures a seamless transition for our students.
• A Quiet Commute: While Mountainside doesn’t have its own train station, its location offers the perfect balance. We’re a quick drive to the train stations in Summit, Westfield, and Berkeley Heights for an easy commute to NYC. This allows residents to enjoy a quieter, more tranquil home life while still having quick access to city life.
