*THIS PROPERTY IS FOR SALE ONLY* Is there a 3-bed single family home in Kingsport with an office/in-law suite, major structural updates, and room for vehicles and hobbies under $400K? 257 Mockingbird Lane answers that need with a 3 bedroom, 2 bath home offering 1,377 sq ft plus a 600 sq ft garage office/in-law suite with its own septic, set on approximately .75 acres and offered at $369,899.
Welcome to this 1949 single family residence that blends extensive updates with flexible living options in a convenient Kingsport location. In 2010, the home underwent a full interior renovation including a complete gut, reframing of interior walls, replacement of floor joists and the main beam, along with updates to the crawl space, electrical, and plumbing systems. The main home features 3 bedrooms and 2 full baths, while the detached 600 sq ft garage office/in-law suite provides an ideal setup for multi-generational living, guests, or potential income use, complete with its own septic system. Below the office area, a dedicated workshop space adds even more versatility. The property includes RV garage parking, a 2-car detached garage, two storage sheds, and a fully fenced backyard, offering ample room for vehicles, projects, and outdoor enjoyment. A large covered front porch creates a welcoming space to relax. Located just minutes from Warrior's Path State Park, this home offers access to recreation and natural beauty while remaining close to shopping and dining. With county taxes only and extensive structural updates already completed, this property stands out for buyers seeking space, flexibility, and long term value.
