ABOUT THIS HOME
Costilla County, CO Homes for Sale
With a permitted septic and driveway and an ~1024'sq framed out, sheathed and roofed 1bed/1 bath home already in place, this property is a great start for someone looking to build their new home at the foot of Mt Blanca! Easy access, about 5 minutes from Hwy 160 and the town of Blanca. A very nice 8'x16' travel trailer, all ready to hook up to the existing septic, is onsite and included in with the property. The unfinished home has been very well built, has a front and back porch, and is partially plumbed. Everything is ready for the right person to come in and install a well, side the building, and get started on finishing out the interior.
