That's insane. Even in rapidly growing Austin, you can get a nice double wide like that one for $90k.
Yeah, they used to be cheap. Right now the market is highly irrational. Some of those premanufactured homes are pretty decent. I looked at one back when I was buying properties to rent. The entire small neighborhood was comprised of them. It was like a regular subdivision, but smaller and less expensive. Not a dump like a trailer park. I think the one I looked at was $45k or thereabouts. It was a plantation for FOP's, so I didn't buy it.
That one mobile home would be a stretch at $7.5k in a normal market.
