The unit mix includes one 2-bedroom/1.5 bath, two 2-bedroom/1-bath units, two 1-bedroom/1-bath units, and one large studio, all positioned to achieve full market-rate rents upon completion. Originally built in 1986 as a mixed-use retail and residential property, the asset’s highest and best use has evolved into a fully residential income-producing investment. The property is well-positioned for a streamlined development process, with full architectural plans in place, including demolition and construction schedules, and all town approvals secured—ready for immediate permit pull. A local builder has already provided a rehab estimate and is prepared to begin work. Additional value can be realized through a large unfinished basement and a two-car garage, offering potential for storage or supplemental rental income. The site also provides ample on-site parking to support tenant demand. Situated in the heart of the village within walking distance to Triple Elm Coffee shop, Bruchetti’s Pizza, A and M Sandown Market, Rockingham Rail Trail, Post Office, Library, Town Beach, the historic Sandown Train Depot and the Sandown Meeting House.
