Amazing opportunity to develop a single family to a 4 floor two family with approved plans included in the sale. The building currently features 3 floors of living space, 4 bedrooms, and a partially finished walk out basement with tenants in place until August 2026. The plans have both units being coveted duplexes with generous square footage and the ability to extend the living area even further by maximizing the by right FAR of 2.0. Buyer has the ability to flip as condos or hold for great rental returns.
