This was considered a win-win situation for both us and our goals (they are retiring and I am just getting started).I secured a cash out refinance in my name in order to pay this family member (and myself) back. 

The securities laws require any publicly-sold securities to be registered, which is an expensive process.  

Granted, that's a big increase but it sounds like you're being more than fair given the cost of the comparable properties. 

Grant street group runs several of them.

@Grant Moffett I have found end buyers before the flip was complete and that's great.

4) I can assess a property and the cost for repairs if I can have access to the property, however, how are the repair costs estimated when access to the property is not granted?

Were you able to secure a long trail of historical rent rolls before purchasing?

Think of all the things that could go wrong and see if the lease addresses them: unauthorized pets or tenants, early termination, security deposit, lease violations, late rent, eviction, lawn maintenance, parking, etc.5.

Also, worst case scenario is if you leave secure job, and lose your $80k in BRRRR.

If you want to invest, do it after you secure your home.
