Property Description

Welcome to this pristine, barely-lived-in 2021 custom-built Colonial on a rare oversized corner lot. Freshly maintained and move-in ready, this home sparkles with modern elegance and thoughtful designer touches throughout. Step inside to soaring 9-ft ceilings, gleaming hardwood floors, custom wainscoting, crown molding, recessed lighting, and a striking one-of-a-kind accent wall in the formal dining room.

The open-concept additional living room/den room boasts a cozy gas fireplace and flows perfectly for entertaining. Upstairs, the luxurious primary suite offers a huge walk-in closet and spa-like en-suite bath with Italian-imported tile, dual vanities, whirlpool soaking tub, and frameless glass shower.

Charming front porch and commanding curb appeal complete the picture. Top-tier finishes, thoughtful decorative choices, and move-in perfect condition make this the standout home you’ve been waiting for in Mount Sinai. Don’t miss it!
