Exceptional mixed-use investment or high-visibility professional headquarters! The historic Nathaniel Hall House (c. 1770) offers a premier triple-stream revenue setup just steps from the quintessential Guilford Green! This versatile asset is ideal for a professional firm seeking an elegant flagship office with supplemental residential income to offset costs-perfect for a law firm, financial group or creative agency. The main level features Federal-style office suites with wide-plank flooring, custom built-ins, and three 18th-century fireplaces providing a sophisticated environment for clients and staff. Residential income is generated by a private second-floor apartment with a spacious walk-up attic, while a detached 2BR “Barn” apartment adds further character and revenue. This is a turnkey opportunity– current residents intend to remain with leases in place through next year. Situated on a .38-acre lot with ample private parking and originally built by the son of prominent Captain John Hall, this trophy asset is located in one of Guilford’s most coveted historic corridors, 6 HOUSES from the Green offering immediate access to community events, boutiques and fine dining.
