Tucked away at the end of quiet Estrada De Costa, a single lane road with just three homes, this unique and spacious 3 bedroom/3 bath lakefront property offers rare privacy, flexibility, and charm. Originally built in 1965 and expanded in 2001, the property includes a 2 bedroom/2 bathroom main house, and a fully equipped one bedroom/one bath in-law suite with its own private entrance, cozy living room, kitchen, walk-in closet, and screened porch with tranquil water views. Ideal for multigenerational living, guest accommodations, or income potential. Saltillo(Mexican) tile flooring flows throughout both living spaces and adds character and charm to every room, while the open layout flows seamlessly for comfortable everyday living. Sliding glass doors on the water side fill the rooms with natural light. The house did have water in the home after Hurricane Helene, so the current owner completed some thoughtful and stylish renovations such as Shaker cabinets, quartz counters, subway tile backsplash, all new LG stainless steel appliances, new AC and hot water heaters in both living spaces, solid paneled doors throughout, Shaker-style double swinging doors for the laundry room, and entrances to Main bedrooms. New roof in 2022 and drain pipes lined in 2024. Located on Lake Rittwood, a serene neighborhood pond teeming with tilapia, turtles, ducks and birds, this home is a true retreat. Stroll into Siesta Key Village, or catch sunset views at the Big Pass/Gulf public access at the West end of Givens St. and Ocean Blvd. This home offers the end-of-the road seclusion, but still close to the wonderful activities of Siesta Key and Sarasota.
