Room rental agreement, or single family rental?

[Michael Ginter]

I am wanting to lease 4 bedrooms to one person. I will maintain one bedroom and the garage for myself with shared living spaces/bathrooms/etc.

Do I have to make a separate lease for each bedroom or can I include all 4 bedrooms on one lease since its all the same renter?

Struggling with what structure I should be using.

Any insight is appreciated.
