I’m thinking about buying a 6 bed house and renting by room in Maricopa county AZ does anyone have any tips and can point in the right direction for the legal bits and pieces I have been analyzing properties every day and plan on buying next August

1st... talk to a local attorney in your area and see if there are any regulations that are unique to your state, county, and/or city (or even subdivision in some places). 

2nd... if the numbers work and you are up for managing six different tenants for a single property then go for it. Renting by the room usually creates more cash flow but requires more of your time to manage.
