There is land that is leased to home owners on some major roads in the National Forest that have been grandfathered in the deal where they can own their cabin and lease the land under that cabin. The lease only gives them access to their cabin and no other land rights to the land itself other then a rental type arrangement with the Forest Service for the land(up to an acre or so).
I don't know the specifics to these type of lease agreements but know a couple of people who are in this type of lease.
