Where do I check the rents for that property?  

It's great that you're checking to see what others are doing, though!

I don't know how investor friendly they are but you can check out lokation Realty.

check out personal capital.

On 1/26/2019 she called Mario to tell him that she didn't want us to move in, so this created many problems for us, we had given notice to our current rental and had given Mario a cashier's check for $10,000 and gave him cash for $1600 for the rent.

@Josh Thomas most cities in Metro Detroit got so tired of OOS investors flaunting the rules via LLCs, as you are suggesting, that they now require someone to be liable that lives within 25 miles of the property - usually a person at a PMC.Most duplexes have a side door that both tenants can use to access basement.

I believe her boyfriend will be moving in so I will need to do a background check on him.

If you check out their website they have tons of articles on developments.

Most of the time by the time I’m running an actual background check/credit check I’m pretty sure the tenant will work out.
