Market gauge is calculated using active listings and pending sales from the most recently available reporting period (Mar 2026 - May 2026).

Year-over-year trends in Mountainside show a market that has cooled slightly in price but intensified in pace. The typical home value over the latest rolling three-month period is down a bit from last year, yet homes are selling dramatically faster, with median days on market dropping about 98 percent to just 14 days.

Over the most recent three months ending in May 2026, supply remains tight and tilted toward sellers. Months of supply has fallen more than 70 percent from a year ago to around 2.1 months, while nearly half of homes go off the market within two weeks and about 58 percent are selling above list price.

Listing and contract activity has picked up compared with last year, suggesting more movement on both sides of the table. Active listings are up more than 23 percent year over year, and pending sales have surged almost 39 percent, even as closed sales dipped slightly. Buyers and sellers who want to navigate these faster-moving conditions can turn to Agent Pronto to connect with an experienced local agent.

“Selling my condo felt overwhelming at first, but working with Tina Torres made the entire process smooth and successful from start to finish. Her professionalism, knowledge, communication and dedication were truly outstanding. Tina was always available to answer questions, kept me informed every step of the way and worked incredibly hard to make sure everything stayed on track. Thanks to her expertise, my condo sold quickly and the Closing process went smoothly. What stood out the most was how much Tina genuinely cared about me as a client, not just about making a sale. I always felt supported, respected and confident that I was in the best hands possible. I couldn't have asked for a better experience and would highly recommend Tina Torres to anyone buying or selling a home. She is truly one of the best realtors out there!!”

“To whom it my concern, It is our immense pleasure to recommend Viola Salvato as a real estate agent for any individual or family searching for the ideal home. Viola had an initial meeting with us regarding our specific needs in a home as well as our budgetary limits. She is highly talented and immediately found us numerous listings of homes. She did not waste our time with homes that were not in line with our needs. Viola is a master with contract negotiation she came up with a deal that was good for us as well as making the seller happy. She knows the area like the back of her hand and there is nothing that escapes her attention when it comes to properties for sale in this area. We found Viola to be a highly attentive agent, almost as if we were her only customers, although we know that was not the case. She returned all phone calls and emails the same day. We never felt neglected or unimportant. She also is highly personable with an engaging personality. She is hands down the best!”

“My agent was Lucy Phelan at Keller Williams, and I had a great experience working with both Lucy and her brother Richard. Both had provided me with their expert advice, they would take extra steps to educate you and walk you thru the home shopping process. They would work on my schedule, try their best to answer all my questions and would point me to the right direction when I was looking for the lender, inspector, lawyer, etc. As a home buyer in this "Bidding War" market, most of my offers were turned down; however, both Lucy and Rich have continuously provided me encouragement to keep trying and looking. I cannot remember how many houses we have looked together...and when I was not able to look at the houses in person, they would video call me to conduct a virtual home showing. In general, they are exceptionally good with people skill, nice/friendly people to talk with and they show care on other things then just home buying. I would like to work with them again in the future and would recommend them to any home buyer/seller.”

“Audra Loccisano worked closely with my siblings and I to sell our parents’ house. She really knew the local Rahway market, as well as needed services and the city building ordinances. Audra had great interpersonal skills, too, and kept in constant communication. And she was especially expert at pricing strategy and negotiations. We were all very satisfied with Audra’s services, with a fast sale at a better than expected price. We can recommend her without reservation.”
