I looked at this, and while it might seem a nice idea, there are problems associated with it. Now it depends on how old you are. Personally I would (and did) buy a house if I was much younger, with the crap that usually comes with it like wife and kids. But if I was single and in my 50s or about, I would question the importance of buying a house when I know I would not pay it off. I know the benefits of owning a house and it has its fair share of pros and cons. Yet 2008 told me a huge lesson: live within your means. A house and a mobile home is the same in my opinion.
I do not like an idea of a typical mobile home. They are usually 24K minimum plus land and septic, electricity etc. They are a huge pain on the ---uvula--- to move and they usually fall apart if you do, and it costs lots to do so and where to put it etc. Buy a used one and it is like buying an old car. Also the land it is on might be rented and that could go up in price too and you are locked in with nobody to sell it to unless you find a sucker.
I would lean to maybe a tiny house with no septic (composting) and solar for 15K or maybe less if you are a carpenter. Or perhaps a van conversion or RV. Lots to think about. But I would have a
big think on a mobile home unless you already have the land and it is zoned.
Sounds like your recent experience, is better suited to something smaller and less attractive to the nut job that usually comes calling. I would hate to experience that, and I am sorry you did, but if you can support yourself without the daily drive, think about getting out and finding something better in this huge country of ours. I'm looking into that, to save 1K a month in rent and having the freedom to travel and afford it. Besides when I am dead who would give a crap? You can bury me in it.
