388 Sea Street Just 800 feet from Keyes Memorial Beach and .7 miles by sidewalk to Main Street Hyannis, 388 Sea Street is a rare coastal property with scale, flexibility, and proven rental appeal. Set on .45 acres with two driveways and ample parking, this extensively renovated compound offers the kind of location that works beautifully for summer living, guest stays, hospitality use, or a mixed rental model. The property is anchored by a spacious main home, which includes 6 bedrooms and 4.5 baths, along with an attached 2 bedroom, 2 bath guest suite. Tucked into the lower rear side of the building is a private studio unit with its own bath, adding another layer of flexibility. A separate two-car garage building completes the offering with a 1 bedroom, 1 bath apartment above. Altogether, the property offers approximately 4, 525 square feet, 9 bedrooms, and 8.5 baths across several distinct living areas. Currently used as a successful hybrid blend of vacation rental and year-round rental housing, the property also holds an active lodging house license from the Town of Barnstable allowing up to 10 individual rental rooms and a total of 20 people on site. Its Residential Congregate Housing zoning further supports a range of potential uses, including an inn, bed and breakfast, or continued operation as a flexible income-producing property. The setting is the magic. Spend the day at Keyes Beach, head into downtown Hyannis for dinner, catch the ferries, explore the harbor, or simply enjoy the convenience of being close to so much of what makes Cape Cod such a compelling destination. For an investor, hospitality operator, or buyer seeking a substantial Hyannis property with rare permitted use, extensive renovations, and an exceptional near-beach location, 388 Sea Street is an offering with uncommon possibility.
