About this home

This as-is home is located in a very rare, wooded setting in the established Howard County neighborhood of Worthington. Comprising 3.76 acres, this amazing property sits on one of two large lots in the neighborhood, is within walking distance of Worthington Elementary, and was appraised in late 2019 for $630k. The kitchen was an add on and encompasses over 400 square feet. The basement has a full bath and can easily convert one of the rooms into a bedroom. This spacious home is in need of paint, carpet, and some improvements. There is future potential for development and/or Howard County programs such as Forest Mitigation and the Real Estate Density Exchange Option. Enjoy the wonders of nature and the amenities that come with this great location.
