About This Home

3772 78th Avenue Se

Effortlessly cool with classic mid-century charm, this 3BR/1.5BA north-end rambler is designed for easy everyday living. The welcoming layout features a light-filled living and dining area, plus a cozy kitchen opening to a sunny patio and expansive fully fenced backyard with lush lawn, all set on a generous 8,793 sq ft lot—perfect for entertaining, gardening, pets, or play. An additional family room with fireplace offers flexible space for relaxing, movie nights, or a home office. A covered area between the home and spacious 2-car carport creates the perfect spot for hobbies, gardening supplies, storage, or a workbench. Thoughtfully positioned off 78th Ave, the home feels tucked away while remaining incredibly connected. Located across from Homestead Park and West Mercer Elementary, and just a few blocks from the heart of downtown Mercer Island—grab coffee, stroll Mercerdale Park, visit the summer farmers market, or hop on the new light rail. Comfort, convenience, and an easy Mercer Island lifestyle come together in this charming home.
