Description

This exceptional 2,652 sq ft retail property presents a prime redevelopment opportunity in historic downtown Gaithersburg, MD. Situated on a 0.27-acre lot, this location offers unparalleled potential for developers and investors. Its strategic location is just 0.2 miles from the MARC Train Brunswick Line and 2.9 miles from a Metro station, ensuring convenient access to the broader DC metropolitan area and its vibrant entertainment hubs and amenities. The property is cleared for demolition by both the city and CSX, allowing for a fresh start on a site suitable for a multi-level building. Extensive due diligence materials are available, including environmental studies (soil tests, stormwater management plan, forest conservation plan), a traffic flow assessment, and a survey. Up to 20 parking spaces are potentially available, a significant advantage in the downtown area. The property is not historically protected, offering flexibility in design and construction. While utilities are currently disconnected, this presents an opportunity to tailor infrastructure to the new development. The seller is open to holding a first deed of trust, contingent on acceptable offer terms. This is a rare chance to create a landmark project in a thriving community. Safety warning: Do not enter the existing building.
