About this home

One block from Inman Square, this property includes two separate structures on a generous 9,120 sq ft lot, a rare size for the area.

The property includes a garage and plenty of off-street parking. The expansive lot and versatile layout may allow for multi-generational living or potential additional dwelling options, subject to local regulations. Convenient to shops, restaurants, and public transportation, the property offers flexibility, space, and accessibility for both investors and owner-occupants.
