Outside of the handful of major metro areas you can get a respectable house for around 100k and a really nice one for perhaps 200-300k. Can you even buy a trailer home in the Valley for 100k?

Edit: I went and looked on Redfin and most trailer homes in the valley go for quite a bit over 100k there are maybe 4 listings for trailers for 100k or less.
