But without the experience, knowledge and capital (actually CREDIT CAPACITY) I accumulated the prior 2 + years, this transaction would not have been possible.

You want to focus on markets that work with your plan and also where you have a personal connection with someone, even if you build that on the internet.

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

i would never tell a random person on the internet where they should live. 

Any local bank that does this kind of financing should be able to approve you as long as you have a good enough credit score and never declared BK.

We also got over 100K in credits for repairs.It was a killer deal.

The trashing of his credit threatened his job.

Interest rates and cap rates change, competition changes, your PM ends up being horrible, lots of variables.Just to throw you a monkey wrench, in your killer spreadsheet does it include the credit score, income, and employer of every resident? 

I am considering doing this with a 0% APR credit card to avoid a loan. 

I've been self-employed for only 6 months, and loans are proving difficult to come by despite my great credit (not to brag, I'm moreso frustrated and seeking help).
