Backing to serene woods with a private backyard oasis and located just steps from the community tennis courts and pool, this home blends timeless charm with extensive modern upgrades and exceptional convenience. A welcoming full-length front porch with wood-paneled ceiling, composition decking, and ceiling fans (2006) sets the tone for the warmth and character found throughout. Inside, newly refinished hardwood floors and fresh interior paint (2026) create a bright, move-in-ready feel across the main and upper levels. The heart of the home is the fully renovated gourmet kitchen (2011), featuring 42" dark wood custom cabinetry, granite countertops, stainless steel appliances, a large center island, and a spacious mudroom just off the kitchen for everyday functionality.
