A truly unique historic property in the heart of El Verano, offering four distinctive residences and a compelling investment opportunity. With established long-term tenants, this income-producing property offers the flexibility to maintain all four rentals or potentially occupy one residence while generating income from the others, subject to existing tenancies and unit availability. Situated across three buildings on an approximately 9,513 sq. ft. level lot zoned C1, the property fronts Bay Street with an alley along the side. The duplex features two recently upgraded residences with solid wood kitchen cabinetry, elegant countertops, laminate flooring, and recessed lighting. Both bathrooms have also been updated with attractive cabinetry and granite countertops. 19090 Bay Street is a two-bedroom, one-bath residence facing Bay Street, while 19092 Bay Street is a three-bedroom, one-bath residence tucked behind it. 19094 Bay Street, the converted barn, is a charming two-story loft-style residence featuring solid wood floors on the main level, high ceilings, and three large doors opening toward the garden. The ground-floor kitchen complements the home's distinctive character, while the upstairs loft includes a full bathroom. This residence also enjoys its own detached two-car garage, plus an additional parking space. 19088 Bay Street, the converted water tower, offers another unique two-story loft-style residence featuring an updated kitchen and bathrooms, fresh interior paint, and a charming spiral staircase that adds to the home's distinctive character. All four residences feature dual-pane windows. Mature trees, inviting patios, and potted gardens create a charming garden-like setting throughout the property, offering a sense of privacy and tranquility. Additional amenities include a separate storage and coin-operated laundry building, gravel driveway, on-site parking, and separately metered gas and electricity.
