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

Year over year, Mountainside’s rolling three-month numbers show some cross-currents for prices and activity. The typical home value over this period is about $1.03 million and is down more than 10 percent from a year ago, even as the median list price is nearly 20 percent higher, reflecting sellers testing stronger asking prices.

Activity levels have picked up notably compared with last year’s same period. Homes sold and pending sales have both more than doubled year over year, while active listings are up sharply as well, suggesting more options for shoppers and more movement overall.

On-the-ground conditions still favor sellers, with only 0.9 months of supply in this rolling three-month window and a seller’s market designation. Yet buyers are gaining some leverage as just under 40 percent of homes sell above list and the average sale-to-list ratio hovers near 99 percent, so Agent Pronto can connect both buyers and sellers with an agent who understands how to navigate these shifting dynamics.

Mountainside offers residents a welcoming, close-knit community with convenient amenities, strong schools, and abundant outdoor recreation.

Mountainside offers a small-town feel with convenient access to major employment centers and services. Located along the Route 22 corridor between Westfield and Scotch Plains, it provides quick connections to Newark and Elizabeth, along with nearby train service via neighboring communities.

Daily life is shaped by easy access to outdoor recreation and practical amenities. Echo Lake Park features trails, picnic areas, and a dog park, while Watchung Reservation offers miles of hiking, a nature center, and scenic roads. Families value the well-regarded Mountainside School District and the shared high school arrangement at Governor Livingston High School in nearby Berkeley Heights.

Errands along Route 22 are straightforward, with supermarkets, fitness centers, and dining options close at hand. Local favorites such as Publick House and Mosaico provide dining without a long drive, and the Mountainside Public Library anchors community programs for all ages.

Housing ranges from mid-century ranches to expanded colonials on quiet residential streets, which can make pricing and competition vary block by block. A Mountainside real estate agent who understands school sending patterns, commute preferences, and local zoning can simplify decisions, reduce stress, and help both buyers and sellers move through the process with confidence by partnering with Agent Pronto.

“If you want to buy or sell real estate in New Jersey, Anna is the only one you should work with. No other agent compares to her. The way she works, conducts business, and communicates with people, along with her deep knowledge of all the details—it's truly exceptional. I’ve worked with her before, and while I was extremely satisfied then, this time she exceeded all expectations and I am simply so happy to have found such an agent. Other agents just couldn't handle it—with them, you only waste time and feel no support at all. Anna, on the other hand, is always available and on top of everything. Her professionalism and dedication are unmatched. I couldn't be happier!”

“Daniel is highly professional and has a team that always responds in a timely manner and is very efficient. The property I had was out of state, Daniel took care of everything that needed to be taken care of and saved me loads of trouble. He monitored the entire process and made sure everything was handled with utmost professionalism. Daniel is definitely the best and I cannot thank him enough for taking care of this for me.”

“I want to take a moment to express my heartfelt appreciation for my real estate agent, Emily. Buying a house is not an easy journey, and my journey to owning home came with so many challenges, unexpected obstacles, and moments when I felt like giving up. But through it all, Emily never stopped fighting for me. She stood by my side, pushed when things got difficult, and continued to advocate for me when I needed someone in my corner. Emily, you didn’t just help me find a house; you helped me fight for a dream. You saw how much this meant to me, and you gave me encouragement and support when I needed it most. Your dedication, patience, and determination mean more to me than words can explain. I know this journey wasn’t easy, but I’m truly grateful that I had you by my side. Not every real estate agent goes above and beyond the way you did, and I will never forget the effort you put into helping me get to this point. Thank you, Emily, for fighting for me, believing in my dream, and helping me get closer to turning a house into a home. You will always be a special part of my homeownership journey. May God bless you for the heart you put into your work and for the difference you make in people’s lives.”

“Roxanne Briano handled the purchase and sale of this property. Roxanne was very responsive to our every need and used her professional skill set to come up with a marketing plan which she ultimately executed to perfection. I would highly recommend any buyer or seller to work with Roxanne in the future.”

“My wife and I had a truly great experience selling our house with the Lacerda Team. Sellibg a two-family house is a complex, even daunting, process, especially after owning it 39 years. But Andrea educated us, regularly reassured us and settled down our anxiety. She communicated with us regularly, every step of the way. Joe competently managed marketing aspects creating media, managing Zillow and similar sites. And Jessie helped in many other ways like placing signs and helping us determine fire extinguisher and smoke detector locations. Due to the rigor and complexity of state and local laws specific to multi-family homes, which has changed dramatically in 39 years, this process could have driven us insane. But Andrea was so helpful, thorough, and compassionate, the process came to a joyful conclusion. Her team worked in the background to market the property, ultimately generating eighteen offers, and once we settled on a buyer, Andrea worked closely with the buyer's agent to keep the process moving forward at a rapid clip. We highly recommend The Lacerda Team!”

“If you’re looking to buy or sell then you have come to the right place. Tracey is phenomenal. From looking at our place and helping us decide on the right listing price in a complex market environment all the way to closing and then helping us find our next home. There’s truly no one better. Tracey is incredibly knowledgeable, has a vast network of qualified and prompt connections (inspectors, general contractors, mortgage lenders, you name it), and is truly in your corner. There was no question too big or small. She took the time to understand us and advocate for us making this an easy stress-free process because we knew we could trust her. She goes above and beyond and will go out of her way to make herself available for calls, to be on-site, and to get you into any property that could be a match. What speaks louder than what we could share is the way other realtors react when they know you’re working with Tracey. Her name is not just known - it is respected. Realtors know working with Tracey means a smooth transaction is coming. She advocates hard for her clients, but is fair, easy to work with and gets deals done. All that we could ask for - and what makes her such a respected professional in the field. We cannot thank Tracey enough and would recommend her to anyone.”

“We had such a great experience working with Pat to find our home in New Jersey! Since we were moving from out of state, we relied heavily on Pat to tour homes for us, and he was incredibly responsive, reliable, and thorough throughout the entire process. He always took the time to send us detailed videos and walk through each home as if we were there ourselves, which made the out-of-state home-buying process so much easier. Pat went above and beyond to make sure we found the right home for our family, and we truly appreciated how easy he was to work with from start to finish. We couldn’t be happier with our experience and would highly recommend Pat to anyone looking to buy a home!”

“Heather recently helped me complete a home purchase and she was truly amazing from start to finish! I came to her after not having much success previously. I had seen 20+ homes before and could not get anywhere. I saw one home with her and she managed to get the deal closed within a month! She is extremely responsive and will go the extra mile every time for her clients! I felt that she had my best interest in mind and was very knowledgeable throughout the entire process. She takes her time with every interaction and every negotiation and truly wants to see you succeed in this journey. She is there for you every step of the way and I could not be more thankful for her endless support throughout this journey. She is so kind, thoughtful, and just an altogether amazing person filled with so much joy and excitement. It is clear to see she loves what she does. If you are in the home buying journey and have been struggling or want to find a home especially in this current market, I highly recommend reaching out to Heather. She will get it done no matter the circumstance! The best part is she doesn’t disappear right after the closing like other realtors. She is there for you even after to help you get adjusted to your new home and be a resource for you as you embark upon this new journey. That itself is rare and just proves her dedication and commitment to providing superior service and instilling trust to her clients! Truly exceptional realtor and so thankful we crossed paths!”

“We are truly so grateful for Caryn and everything she did to help our family find a rental home. This was not an easy search for us. We faced quite a few challenges along the way, and there were moments when we honestly wondered if we were going to find a place in time. But Caryn never gave up on us. She worked so hard and was incredibly persistent in helping us find a home. She was constantly communicating, following up, searching for options, and doing everything she could to help. What touched us the most was that she continued to be there for us even after hours and even while she was out of state cheering on and supporting her own children during their competitions. She still made time for us and kept working on our behalf. That kind of dedication meant more to us than she probably realizes. Caryn never made us feel like we were just another rental client. She genuinely cared about our family and understood how important it was for us to find a place we could call home. She was patient with us, reassuring when things didn’t work out, and kept encouraging us to keep going when the search became overwhelming. After everything we went through, finally finding our rental home was such a huge relief. We are so thankful Caryn was there with us through the entire process. She truly went above and beyond, and we will always remember how hard she worked for our family. Caryn, thank you from the bottom of our hearts. Your kindness, patience, persistence, and dedication made such a difference during a very stressful time in our lives. We are so grateful we found you and had you in our corner. And when the time comes for us to purchase our own home, you will absolutely be the first person we call. We would be honored to have you help us with that next chapter too. If you’re looking for a realtor who will genuinely care about helping you find a place to call home, we highly recommend Caryn. She truly goes above and beyond.”

“The most positive experience I could have possibly imagined! There's really no words to describe how wonderful it was to work with Frank. Selling an older house can always be a challenge and there will always be tons of curveballs and questions along the way. The communication was above and beyond anything I could have hoped for! He handled all the challenges with grace and enthusiasm. His knowledge of the area as well as his understanding of the market made him the perfect person to work with. Selling a house can usually be a very difficult and sensitive step in a family's history and I was able to rest easy during it all knowing that all the details and difficulties were being thought of daily by Frank. He also helped suggest services to help move things along during the process (cleanouts/donations/etc). Couldn't recommend him any more!”

Thank you soooo much Jessenia!”
