Find a house to rent. We did this a couple times and added people to offset costs. Had a nice two story summer home on top a hill and a walk out, elevated deck that overlooked the valley, including the AT, below. It had a one car garage. It was just off the 28, just past the Hike Inn and the odd store that has half a 70's era areo cruiser motorcycle as it's signage. It was quiet, inexpensive and easy to get to R'ville or Fontana.
Not the actual house, but very close to it.
