Not sure if you are aware but mobile (manufactured) homes that are moved to a second placement are no longer eligible for FNMA financing.  

It's not too difficult, if they haven't already they'll send you a very one-sided purchase agreement to docusign and give you wiring instructions for your EMD.

BUT I have called around to local banks and credit unions and found a few who will lend on "manufactured" not in parks.  

Such assignments are rarely done and with new lending rules being applied, it's doubtful that you will be giving proper instruction to a seller, and you may then be considered a loan originator, creating an obligation for another party!

I create notes for SDIRAs and they contain the property information including the State the property is located in, but the State of the IRA custodian, or the State where the investor, is not included on the assignment agreement.Your IRA custodian should be able to instruct you.  

When looking at the courses required for the B.S. degree, I realized that MET is much more focused on things like manufacturing machines and automation, which I have almost no interest in.

The Manufactured Housing Institute has a one day course on Tuesday May 3d  in Las Vegas "Developing with Manufactured Housing" that would be an ideal starting place based on what you have written.

Think recent felony convictions for murder, rape, theft or drug manufacture or distribution.But blanket statements regarding arrest records might get you into hot water.HUD is recommending that you examine each tenant on a case by case basis.We've been having a lively in-house discussion here at BiggerPockets, and @Brandon Turner said "HUD wants us to look at each case specifically and decide if it was ‘bad enough?”

In the last 6 mo new opportunities from the home manufactures have come to market.  

Edit: Also I found this caveat, "Generally, your business must create or retain one job for every $65,000 provided by the SBA, except for small manufacturers, which have a $100,000 job creation or retention goal"
