Periodically I look for a patch of land within reasonable driving distance of the SF Bay Area, for use as a private, multi-night, club, friends and family camping and observing locale. Recently I've located two historic pieces of property in rural San Benito county, in a blue-gray zone. One is the remaining parcel of and old Spanish Land Grant rancho (~170 acres) and the other is a historic mine site where the California state gem and other rare minerals were first discovered (~260 acres). Both have power, springs and seasonal creeks. The larger parcel is actually cheaper by $75k. Either can be reached within 4 hours from Petaluma. Both have forests, rocky spires and flat, treeless sites suitable for observing. One is almost surrounded by BLM land. Nether would have much traffic. Neither has improved driveways, and would require some grading and graveling. The seller is willing to finance one of the parcels.
What considerations should be going through my head?
