Lake views in a prime Lucas Hill location! Don’t let its diminutive front profile deceive you...this home offers a surprising amount of space and so much potential. Add your own signature updates to its classic mid-century design or start fresh on the nearly quarter acre lot with scenery stretching all the way to Lake Washington. Expansive gathering spaces are spanned by windows and a deck all ideally oriented to maximize the view. A spacious eat-in kitchen and three bedrooms complete the main floor, while the fully finished daylight basement offers two more bedrooms plus a second kitchen and separate access—perfect for a guest/nanny/rental apartment or multi-generational living. Tucked down a serene neighborhood street, you’d never know that you’re just blocks away from the town center and easy I-90/light rail access to Seattle or Bellevue. Walk to shopping and dining, as well as Mercer Island’s renowned parks and miles of trails. Opportunity knocks!
