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

Year-over-year, West Islip’s rolling three-month numbers show prices moving higher while inventory tightens. The typical home value is up about 8 percent from a year ago, and homes sold have increased more than 27 percent even as active listings are down roughly 17 percent.

Looking at the most recent rolling three-month period through September 2026, supply is especially lean. Months of supply has fallen to about one and a half months, down nearly two thirds from a year earlier, and median days on market has shortened to just three weeks.

Demand pressure is also visible in how homes are selling. Nearly three quarters of recent sales closed above list price and the average sale-to-list ratio is a bit over 104 percent, both higher than a year ago and signaling strong seller leverage. Buyers and sellers can both benefit from an Agent Pronto–recommended agent who understands these conditions and can guide them through this fast-moving West Islip market.

“Anthony was a wonderful partner in getting our house sold recently. He cared about our needs and ensured that the whole process ran as smoothly as possible for us from start to finish. He respected that we had animals in the home during open houses by limiting people in our home all at once. And he took the utmost care that our family/possessions were protected during open houses. He was extremely knowledgeable when we had questions or needed advice on our house sale and relocation to another state. He made everything seem a little less nerve-wracking and unsure for us. I would recommend him to families in the LI NY area. We appreciated his help very much!”

“I was a North Carolina transplant looking to sell my property in central Long Island, NY. Samantha had connections to a an excellent real estate attorney, a junk removal service that worked at an acceptable cost and on short notice. She was knowledgeable, responsive, and really went above and beyond to make sure I felt connected - in spite of navigating the process from states away. I never felt a need to go up to NY and handle something myself. I would use again if I go back to Long Island.”

“Working with John to find our family's forever home was truly a fulfilling experience. As we transitioned from a smaller home into a space that would better fit our growing family's needs, having him by our side made all the difference. From day one, John took the time to deeply understand what we were looking for. Rather than wasting time or distracting us with properties that weren't a true match, he kept us laser-focused on homes that aligned with our vision and goals. His market knowledge and sharp intuition meant we were only seeing properties with genuine potential. Throughout the entire home-buying process, John was remarkably accommodating, patient, and consistently clear and responsive in his communication. Buying a home can be overwhelming, but he provided steady, expert guidance, helping us make the best strategic decisions at every turn. What truly sets John apart is his masterclass in transaction management, persistence, and strategic foresight. In our case, we weren't the initial offer accepted on the home we ultimately bought. Where another agent might have moved on, John saw it through. He maintained constant diligence, advised us on crafting a strong, competitive offer, and kept us in prime position so that when the original deal fell through, we were ready to step seamlessly into place. Beyond his incredible hustle and market savvy, John proved to be an invaluable advocate during negotiations and helped effortlessly navigate the complexities of home inspections, appraisals, and coordination with our lender and closing team. His professionalism, calm demeanor, and thorough execution ensured a smooth transition from start to finish. If you are looking for a realtor who truly listens, stays in your corner, and delivers exceptional results, we cannot recommend John highly enough!”

Whether it was day or night, he always made time to answer our questions, no matter how small, with patience and attention to detail. John made what can be an overwhelming process feel smooth and manageable. We always felt like a priority, and we truly couldn’t imagine working with anyone else. If you’re looking for someone who will go the extra mile and make your home-buying experience as stress-free as possible, John is the person you want by your side!”

“Working with Maria to purchase our first home was nothing short of amazing. Not only was she kind, friendly, and extremely knowledgeable, but she also made the home buying process FUN!

Even during closing when we hit a few speed bumps, she was right there making sure everything was smoothed over. I could not recommend her more!

“Kerri and her team guided us through every step of the selling process with total professionalism and patience. They gave us practical advice on how to stage our home, hired a fantastic photographer, and marketed the property brilliantly. Because of this hard work, our home sold quickly and for a great price. Communication was always prompt, and we felt completely supported and informed the entire time. We highly recommend this dedicated, honest, and truly effective real estate team! The buyers' team turned out to be completely unresponsive and inadequately prepared. Despite these major roadblocks, Kerri and her team managed the situation flawlessly. They stayed incredibly persistent, anticipated the other side's shortcomings, and proactively pushed the deal forward to ensure we closed successfully. When we needed to take care of a few minor fixes to head off potential inspection issues, Kerri immediately connected us with trusted professionals who responded right away. She also provided us with a legal reference whose team was absolutely fantastic—quick, responsive, and attentive to our needs. They even went above and beyond by assisting the buyers’ attorney during closing to help ensure everything went smoothly. Thanks to Kerri’s strong reputation and excellent professional network, everyone moved quickly, saving us valuable time, stress, and frustration. If you’re looking for a dedicated, sharp, and truly effective team with an exceptional network and the ability to navigate even the most challenging situations, look no further than Kerri and her team! We couldn’t have asked for a better advocate throughout the process.”

“It is my pleasure to write a review for Susan. She made the whole process effortless from the initial meeting to the closing. She immediately had clients lined up to see the house and even kept showing the house after we received an offer. In her words, the house isn't sold until we get to the closing. We were able to get well above our asking price. All through the process Susan communicated exactly what was happening. In the real estate world Susan is a real gem. I whole heartedly recommend her services.”
