A rare Sausalito legacy property with sweeping water views and a half-century of history waiting to become yours. For the first time in more than 50 years, 147-149 Filbert Avenue is on the market! A stunning side-by-side townhome-style duplex perched in one of Marin County's most sought-after waterfront communities. Each of the two mirror-image units offers 1,305 square feet of beautifully laid-out split-level living. The upper level is designed for everyday life and entertaining, featuring an open living and dining area, a well-appointed kitchen with pantry, and a powder room all crowned by soaring vaulted ceilings and flowing directly out to a private view deck. Step outside to panoramic vistas of Richardson Bay, Mount Tamalpais, and the glistening marinas below, and warm up by the wood-burning fireplace on cool Marin evenings. Head downstairs and you'll find two spacious bedrooms each enjoying those same stunning bay and mountain views with walk-in closets, a full bathroom, and a full-size in-unit laundry closet. Central heat and a full-size water heater in each unit complete the picture of comfortable, turn-key living. Unit 147 is home to a long-term tenant of nearly 24 years, currently paying $3,550/month a testament to the enduring desirability of these homes. Unit 149 is ready for an owner-occupant or a new tenant at a projected market rent of $6,000+/month. Both units include 2 covered carports and storage (4 total), with ADU expansion potential for buyers looking to maximize long-term value. Conveniently located just a short distance from Schoonmaker public beach, Dunphy Park, and Sausalito's world-famous waterfront dining and shops. Muni ferry and Golden Gate Transit provide an easy commute to San Francisco. Properties like 147-149 Filbert don't come around twice.
