I live in a double-wide 3-bedroom manufactured home in the Sierra Foothills.
It cost me less than half the median CA home price, with 7 acres, most of which I made walkable. I just had a nice morning walk through my "arboretum" of mostly manzanita plants. Real pretty ones, and I took some nice photos.
I could't move the home, nor place a new one in most locations, including the vicinity of my local downtown area. I checked, just for jollies.
Land costs drive CA housing. Look at charts or ask ... you know who.
