The big issue comes in with the repayment clause on the loan if you lost the job, as it would put you in a cash call type position.Ideally you would use the money on a down payment on a BRRRR scenario- and then when you refinance you repay the loan balance.  

Or are there some issues I may be looking over?

I would be more concerned about 'issues' than a particular score. 

You have a concrete slab settlement issue that most like tied to a foundation issue as well.

I am curious if anyone has dealt with this issue, and how you moved forward.

We had issues with all of those on ours.)That home was not in Cleveland, but was in Dallas where I lived at the time.  

May not work, but always worth asking them to get it taken care of, some liability issue potential there. 

I've received a request to provide professional pest control service from tenant to help eliminate pest issue at the rental property. 

At the same time, I think the relative rarity of duplexes/triplexes/quads could be a competitive advantage distinct from the hundred of competing offerings in north Dallas.

Receiving rent payment is your only issue, stay out of his personal life.This is one of the reasons I never rent to anyone that is self employed.
