As far as I know any bank in Ukraine will give this return or more with a regular savings account. 

So far in contacting local banks and credit unions, I have learned that credit unions won’t finance to an llc and banks are pretty limited.

Is there a bank or lender in MN that allows property transfer under LLC?

I had initially planned to finance the rehab with cash and creative financing (lines of credit and such), and then financing it all through a bank.

And would did you start buying outright or did you get bank loans?

According to public record it is not bank owned

Took more than 1 month to receive my money back.I invest in E cleveland coz banks are hard to deal with specially when ur self employed.

Last, if the point is to make the best return on your investment, why not utilize bank financing and develop a self-storage facility instead? 

I have tried with two smaller lenders(National Bank of Arizona and OneAZ Credit Union) and they have both dragged it out for several months before deciding they wouldn't do the loan for what I perceived to be fairly silly reasons(Management didn't like that the tenant had only been in for 1 year, Management didn't like that the structure used to be a residence, management didn't like that 3 years ago I took a loss in a completely unrelated business etc.)I am hoping that someone out there has had some success purchasing or refinancing commercial property like this in AZ and can put me in touch with someone who actually completes deals like this.

Your best bet is likely a local bank.
