Then, the contractor is left with burned gas, burned time, opportunity costs, and zero reimbursement.

The note is secured by land only and has a mobile on it which is personal property and is not a part of the note.

There are 4 burned out properties right next to the one on S, Campbell.Also I am not impressed with her work. 

I'm not sure If your familiar with the Green Tree Golf Course area of Victorville but there's a few blocks of homes in there that are mobile homes on permanent foundations.

@Nicholas Novak  What year is this mobile home?  

I choose cash flow as my metric becase investing for appreciation is speculative and if you speculate incorrectly you get burned. 

“The auditor, twice burned, is cautious now, but he looks carefully and decides there’s no way this guy can manage that stunt, so he agrees again.Ralph stands beside the desk and unzips his pants, but although he strains mightily, he can’t make the stream reach the wastebasket on the other side, so he pretty much urinates all over the desk.The auditor leaps with joy, realizing that he has just turned a major loss into a huge win.But Ralph’s attorney moans and puts his head in his hands.”Are you okay?”

If we were to put a new mobile/modular on it, we'd be looking at about $150,000 new, and then you'd have a whole lot of depreciation, stigma, and more difficulty in financing. 

We escalated to multi family, commercial and even a mobile home park. 

If I was in your shoes, I'd learn a few things on first one then hire a pm. 20-30 units, your phone will ring non stop and burn you out.
