Hey Rafal, since you're looking to invest in the Midwest market my recommendation is for you to check Ohio.

Require background checks on all adults living in the house.

@Danny McCarthy your work background shows in your systematic approach.You should also set yourself a deadline for buying a rental.For local clubs, check out REIAofOakland, MREI & Renegade Detroit Investors.Regarding your plans, great approach for first 1-2 properties, but then you'll have scaling challenges.

Have you checked on AirDna or similar sites to see whether short term rentals make sense in Binghamton? 

I'm not sure how AZ pays, but you'd want to check the GSA website to get an idea of per diem rates in your area.
