About This Home
As of May 2026Your home in the mountains with downtown Boulder just 15 minutes away. Wide views of the eastern plains and mountains to the east and south. This is a great neighborhood full of people looking out for each other, but feels private and secluded. The home has enjoyed significant remodeling inside and out with new carpeting, wood floors, a high-efficiency wood burning fireplace insert, a newer roof with impact resistant shingles, water softener, and new septic tanks and pumps for years of reliability. The main floor is full of sunshine and great views from every window. The regraded back yard with a custom stone retaining wall provides plenty of space for pets and parties. A very nice home at an amazing price.
