Exceptional opportunity to acquire The Allen Block, a historic 15-unit brick rowhouse portfolio in the heart of Cambridge. Located at 177–183 Harvard Street, the property consists of five Mansard-style attached buildings, each containing three units (1 one-bedroom, 1 two-bedroom, and 1 three-bedroom) for a total of 15 apartments. The property also includes unfinished attic space and high-ceiling basement areas, offering additional value-add potential. A contributing structure within the Old Cambridgeport National Register Historic District, the striking façade features distinctive round bays rising through the cornice, arched windows and entryways, recessed entrances, and ornate period detailing reflecting late-19th-century Cambridge craftsmanship. Prominently positioned at the end of Cherry Street, the property offers large unit layouts and significant upside through renovation and rental repositioning. Ideally located minutes from Harvard, MIT, Central Square, and Kendall Square.
