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.
