Single Family Home for sale in Centereach, NY

for $749,000 with 4 bedrooms and 3 full baths, 1 half bath. This 1,892 square foot home was built in 1997 on a lot size of 0.53.

PRIDE OF OWNERSHIP And yes, you’ll notice it the second you pull up. Don’t worry, the curb appeal won’t bite…unless you insult the mailbox. Welcome to this BEAUTIFULLY MASSIVE Colonial at the end of a Cul-de-Sac. Translation: less traffic, more peace, and neighbors who actually wave instead of stealing your Amazon packages. 4 Bedrooms / 3.5 Baths which is enough space for a home office, gym, guest room, or that weird “I’m gonna start a band” you’ve been planning since 2019. Step into a SUN-DRENCHED foyer with porcelain and hardwood floors that scream, “Look at me, I’m fancy!” The oversized den comes with a wood-burning fireplace, perfect for cozy nights, Hallmark moments or dramatic staring contests. Formal Dining Room? Check. Formal Living Room? Check. Hosting Holidays? Congratulations….it’s now your life sentence! The GORGEOUS Kitchen (updated 2020) is basically a chef’s Instagram dream: Quartz countertops, stainless steel appliances, a backsplash that whispers, “Yeah, you cook like a pro,” and sliders to the backyard so you can escape before anyone asks you to wash the dishes. Oh, and a Butler’s Pantry because sometimes you want to feel fancy while hoarding snacks. Beautiful Sliding Barn Door opens to a Mudroom/Laundry combo with enough space to pretend you’re organized, you know, until the kids show up. Upstairs: Master en suite with Full Bath, Tub, Separate Shower, and Walk-In Closet that’s basically a boutique where nothing ever fits quite right. Three more Large Bedrooms and a Fully updated Bath. Room for everyone or just enough space to hide from everyone. Need more space? Done! Full Finished Basement with Separate Entrance. Perfect for Mom/Dad, Teenagers, a Rec Room, or a top-secret “DO NOT ENTER” lair. Upgrades that make this house smarter than most people you know: BRAND NEW ROOF 2023, because we love shiny things! 2-car garage (or 3 if your cars are tiny), Attic storage, 3-zone Natural Gas Heat, 2-zone CAC, IGS, 80-gallon Gas Hot Water Heater because teenagers take 2 hour showers, 2 cesspools (located in front, pumped 2023) Backyard? Trex deck + Fully Fenced = low maintenance, high enjoyment. Perfect for BBQs, Cornhole, or just staring at nothing while sipping something strong. Location? Close to LIRR, Shopping, Pt. Jeff & Patchogue Nightlife, and all the things you actually use…not your neighbor’s life drama. Bottom line: This isn’t just a House… it’s the one where you walk in and immediately start rearranging imaginary furniture like a pro. Don’t wait! Homes like this fly faster than a kid who sees the ice cream truck.
