If the road is indeed private, I would strart finding out real fast what the easements are (in writing). Do not go by any assumptions or "local knowledge" especially if you don't have road frontage to a public road.
I've seen a situation where a road that was thought to be a public road was in fact private. One of the interior lots did not have an easement and resulted in a very lengthy court battle for the property holders. In the end, the guy was landlocked and had to pay money to get back what he previously thought was an easement. It wasn't cheap. Those guys don't talk to each other any more either
