I was thinking of doing Airbnb arbitrage in Cincinnati but discovered that there is a restriction that the STR operator has to live within 50 miles of the property.

But we are testing this now.We operate 7 str's out of state...

What are operating expenses of each?

I saw I need a TPT license to operate an Airbnb, do I also need a buisness license ? 

You will want to structure the LLC operating agreement where the lowest credit scores own the least in the LLC.

It's finally a passive operation for me.

I am not making any conclusions just doubting, as previously mentioned, if a 30 year conventional mortgage (nonconforming, but standardized within the banks operations somewhat), necessarily excludes renting it out. 

I am expanded my door knocking operation to include other people within my company.

I’m just a moderately successful multifamily operator and flipper with an idea.

What your mentioning about their awards and reviews tell me is that they're great business operators, which is great for your investment.
