I'd say some asset based lenders couldn't care less about credit score. but they will ask for previous huds to verify experience.

How do I verify that the insurance of the company covers the employees on site? 

Since it seems to only be 21 units you should be able to verify all the leases one by one once your in due dilligence. 

I would first verify that he has savings to carry him through any struggles he might have the first year.

Get a copy of the lease, if there isn’t one get an estoppel agreement w tenant, verify previous rents to current owner via bank statement.

Hi Bigger pocketsI've called two property management companies to verify references listed on an application, however they won't release ANY information to third parties. 

TRUST BUT VERIFY.

Some lenders may verify, with no income verification, but with a higher interest rate, but this is something I need to do more research on and very much welcome any suggestions on any reputable companies I could work with.On that note, I am roughly familiar with a federally insured Title 1 loan that would even be applicable to properties one does not own!

I know in our area here.. most realtors simply are not going to work with contracts that don't have POF's  they have trained their sellers that its a waste of time to work with any contract that does not have POF>and not just mail order internet POFs must be from local reputable lender that they can verify..

Assuming everyone who is living there to be on the agreement, but that leads to the next question.How do you verify income?
