Both homes have been freshly painted on the exterior and benefit from updated sewer and water lines, creating peace of mind for future maintenance. A shared backyard sits between the homes, perfect for outdoor enjoyment or creating separate private areas. Parking is on-street, consistent with the character of historic urban living.
