My house in Florida, for example, STR permission is explicitly included in the HOA covenants.

I'd hesitate to buy a business that is based on annual leases (even with extension clauses) and permissive regulations, as well as previous relationships.

I don’t even have any permissions to rent to section8 tenants.Appreciate your inputs Thanks

There has been many times when leads come to me in preforeclosure, ready to sell their home for next to nothing and I, with their permission, work out a loan modification with their lender helping their payment plan and writing them our tactics that I tailored made to eliminate debt by using a few trusted applications.  

You need the persons permission to text them. 

At about the year mark we asked permission over the phone to get 2 cats which we did.

I know Jersey City is quite openly permissive about Airbnb, but I'm not so familiar with short-term management companies per se.

Finally; be sure to get permission from the lender to transfer the property to the LLC in order to make sure the "due on sale" clause isn't violated.

I agree with @Norm Kopesky, get docs and past utilities from the seller or get permission from the seller to contact utility company.

If the STR strategy is the only strategy that makes the property pencil, be sure to purchase in a market where the use is allowed, the use requirements is protected by the permitting and licensing and the permissions are transferable through a sale.
