Escape to your own private mountain hideaway! This unique property offers a blend of charm, functionality, and plenty of extra space to make your own. A brand new chain-link fence secures part of the lot, and the oversized wraparound deck invites you to soak in the peaceful surroundings from multiple vantage points. Inside the main home, an open floor plan centers around a cozy fireplace, while large windows flood the space with natural light. The primary bedroom includes an attached half bath, and the full bath is conveniently located near the main living areas. Downstairs is where the potential really shines—discover a 19x7 enclosed laundry porch plus multiple bonus spaces below the main level: a 16x15 finished room perfect for a home theater, gym, or game room, plus two additional areas (12x9 and 9x7) ready for your creative vision. Power is already connected throughout, and the largest bonus room even includes a sink. Whether you’re looking for a weekend escape, full-time living, or a rental opportunity, this mountain retreat is packed with possibilities. Come experience it for yourself!

The RR Use Regulations are intended to create and enhance residential areas where agricultural use compatible with a dominant, permanent residential use is desired. Typically, the RR Use Regulations would be applied to rural or semi-rural areas where urban levels of service are not available and where large lots are desired. Various applications of the RR Use Regulations with appropriate development designators can create buffers between residential and agricultural uses, family or small farm areas, or large lot rural residential developments.
