Wake up to the gentle movement of the water, sip your morning coffee on your private rooftop deck, and watch the city come to life from your own floating retreat on Lake Union. Nestled in a desirable 40' x 12' inner slip, this charming 480-square-foot houseboat offers a rare opportunity to embrace Seattle's iconic waterfront lifestyle. Inside, you'll find a comfortable and efficient living space designed to maximize every square foot, creating a cozy sanctuary that provides peace and tranquility. The real magic happens outside. Spend evenings entertaining friends on the rooftop deck while taking in beautiful territorial views as the sun sets over the lake. Enjoy paddleboarding, kayaking, boating, or simply relaxing waterside while surrounded by the unique energy and community that make Lake Union one of Seattle's most sought-after destinations. The monthly slip lease of $1,590 includes water and garbage service, making ownership simple and convenient. The home was fully rebuilt in 2013, is individually metered for electricity, and includes a 30 amp panel, 25-gallon black water tank, and 30-gallon water tank. Whether you're searching for a peaceful escape, a full-time waterfront residence, or a one-of-a-kind Seattle experience, Sounder offers more than a place to live—it offers a lifestyle that few ever get the chance to call their own.
