Finally....
Something I know about! I live in a fine, mo-bile home.
I'm assuming it's attached to a piece of land and not being moved? If so, is it on a "permanent foundation" ? Brick or block underpinning, basically. If it isn't, you or the next buyer will likely be required to retrofit one and they'll probably want the pillars to be mudded to "hold them together"...or some crap like that. Honesty, none of it makes sense to me. You can still move it, it justs cost more now.
If it's in good shape otherwise, it might be a decent flip, but I'd determine beforehand if it needs a new "foundation". A buddy of mine had to have that done and it cost him around 8,000 bucks. Other than that...normal house stuff. HVAC, roof, etc. I'd definitely crawl under it and check out the insulation and check the floors for soft spots though. Oh, and the vapor barrier on the ground.
Mine is a 2014 model and they're drastically different from just 10 years prior. It's got 5/8 Advantech flooring, architectural shingles, finished drywall, flat ceilings, normal sized appliances, fixtures, windows, and doors.
