No you could just arrange a regular sale, as long as the sale price is at or above everything owed. 

You can store the collateral file yourself or pay a company to store it (sometimes through the servicer).

Seems fairly reasonable if you budget other income for the final payment.A huge benefit here is that the property goes into your regular portfolio instead of remaining in your SDIRA. 

Whose credit is improved by making regular payments?

Would any recommend using FHA loans for or a Regular Home loan for purchasing a multi family property?

Why not get a regular mortgage and just pay that back faster? 

In Ohio, I can direct how the work that I pay for is done.In OHio, in the regular case, 24 hour notice is required, in this case, I'd attempt to contact the tenant and leave a message, but no notice is required for emergency work, so I'd feel ok about giving access.

I mean there is no real threat there unlike a regular strike. 

If you can connect with a lender or broker who works regularly with investors (or know of any investors yourself) there is a niche to be carved out. 

Look for an Investor Friendly Realtor that not only understands the regular transactions in RE, but also understands the ins and outs of the investment world.
