The oldest home in Magical Martindale! Built by the town doctor, Dr. Lawson for his family between 1898 and 1900 and located in the Martindale Historical District, this 2,994 square-foot Queen Anne Victorian has passed through only four owners in its history. Situated on a block-deep 0.689 acres with mature trees, the home features a wraparound covered porch, hardwood floors, natural woodwork, multiple living and dining areas, transoms throughout, and five fireplaces. A rare find for the area, the home also includes an unfinished basement, offering storage or future potential. The original carriage house now serves as a 2-car garage, adding to the property's historic character. City water and sewer and central HVAC add everyday convenience to the charm. The property also has a grey water system that keeps the giant trees happy. Walk across the street to the San Marcos River and all that Martindale has to offer. A rare opportunity to own a piece of Martindale history - and the possibilities are endless! Showings are by appointment only.
