If you are taking out a conventional mortgage of any kind, you can't buy in the LLC as it does not have two years of tax returns.You are also asking if an entire state is good to buy multifamily, which means you are too soon in the process to even talk about buying.

Charge the tenants a higher rent rate and include utilities with their rent.
