While you’ll probably be able to eventually prove you’ve been living there.

I live in Farmington Hills.

Where are you living at this point?

I am interested in buying a long-term turnkey property in a nice area (I live in San Diego so this property would have to be out of state).

I am new to real estate investing and got into it because of the book The House Hacking Strategy.I live in San Diego; the rent is just crazy.

I have lived in the US for about 10 years.

Quote from @Jemini Leckie: Hello, I am trying to understand the Orem, city code to determine if I am allowed to rent my basement ADU that I currently live in two a couple cousins and their friend.
