92 Cass St, Portsmouth, NH 03801

Property Description

92 Cass Street offers a unique mixed-use property consisting of five residential units and a detached commercial building, currently occupied by an established pet-grooming business. The residential building features a varied collection of apartments offering 1 studio, 2 two-room studios, a one-bedroom, and a two-bedroom arranged across two floors, while the detached commercial space provides approximately 520 square feet of additional income-producing space. The property also includes on-site parking, an especially valuable amenity in Portsmouth, and shared outdoor spaces for the residential units. Currently fully occupied, the property offers an established rental history with several long-term tenants. Existing residential rents are noted by the seller as being well below current market value, presenting meaningful potential for future income growth. The combination of residential and commercial tenancy provides a diversified revenue stream and makes this an appealing opportunity for investors seeking a Portsmouth asset with both immediate income and long-term upside. The property has also benefited from several important improvements, including newer furnaces in both buildings, replacement windows, recently painted exteriors, a new water heater, and a newer roof. The main residential building was painted in 2025, the commercial building in 2024, and the commercial heating system was replaced in 2025. Located on a compact 0.09-acre parcel in Portsmouth’s CD4-L2 zoning district (permits 5-8 units), 92 Cass Street presents a compelling opportunity to acquire an established six-tenant mixed-use investment property in one of the Seacoast’s most desirable and supply-constrained markets. Property sold as is. Some photos have been digitally modified to remove tenant belongings. Showings start October 13th.
