I'm brainfarting on a story I enjoyed a while back. No luck when searching mountain in title or description. Here's what I remember:
Long story written in a daily life type style. Man buys a house on a mountain. Meets neighbors who are elderly. House is quite small and rustic in the beginning. He ends up with a Mexican girl and her mother. Has lots of babies. As time passes and his family grows he adds on and improves the house. He starts farming and the farm expands becoming a business. He makes a deal with a telecom to cut down trees for paths for them to run lines That grows and becomes a business too. He gets fed up with the poor roads and so ends up taking over creating a business paving roads and plowing snow. At some point he ends up finding some secret stash of confederate gold that he stashed away and sells in nearby towns. Old granny neighbor dies but he feels her spirit in the mountains appreciative for him living well there.
Pretty much a nice chill and relaxing slice of life story of a dude living well on the mountain and helping others along the way.
