Strongly suggest you to use the BiggerPockets Calculator as well as look into Lease Options as that might be another exit strategy to save on the repair, hoa, property manager costs. 

Does anyone have any suggestions on how I can quickly build my buyers list so I can start moving properties?

During the inspection they did not find anything to suggest that the foundation has issues (i.e. no issues closing doors, cracks in walls, windows not working. 

Anyway, would love your suggestions...Thank you!

Note: I am aware of online applications like cozy that makes sure they fill out and pay their background/credit check but the applications for those types of software doesn't cover everything I want to ask and Brandon suggested paper applications is the way to go so it being my first rental I'll follow his advice on that but I just need a robust way of doing it.3.

Any help would be greatly appreciated and I am open to any ideas and/or suggestions!

I would suggest you to try PeerStreet.
