Located at 266 Calle de San Francisco, this remarkable six-story building stands as one of the tallest and most iconic landmarks in Old San Juan. Originally constructed in 1925 and home to the Singer Sewing Machine Company when it opened its doors in 1929, the property carries with it nearly a century of history and prestige. With 12,350 square feet of interior space and serviced by an elevator, the building features five full-floor one-bedroom, one-bathroom lofts alongside a ground-level commercial space on one of Old San Juan's most vibrant streets. Its architectural significance, prime location, and steady rental history in long-term income make it an exceptional investment. Beyond its current configuration, the building also presents an extraordinary opportunity for redevelopment through tourism tax credits or as a short-term rental property, capitalizing on the city's thriving tourism industry.
