@Michael Pursell following up on @Charlie MacPherson good comment you also may want to pay attention to the exact wording of this stuff and how its individually interpreted by the various building departments: Accessory Dwelling Unit, In-Law and other terms may mean something slightly different town by town and be treated differently, likewise if you owner occupy or not. 

If demand stays high.....not so much.Broken record here, but look closely at where we are in the r.e. cycle and try to size up the potential for supply saturation.

As Chris mentioned, know the individual state laws.

I would not contact banks individually and instead let a broker tell you what you can qualify for and the best interest rates.

In FL, my wife and I turned our individual houses into rentals when we bought a house together that also had a carriage house so we had 3 rentals.

Wife is suddenly back demanding full access to the apartment and is damaging the property (broke door and locks in an argument) to prove her point.

Rochester market is very strong and the rental demand is high.

Legal can come later, especially if you are purchasing multifamily as an individual. 

Hey BP, I'm buying my first property using my LLC and Im curious about pulling money out as a company vs an individual.

Highend AirBNBs generally do well in high demand resort type areas.
