House Hack/Renting out per room

[Hunter Rademacher]

Newbie here starting out, that is about graduate college and is looking into buying a multi family to house hack. The certain house I am looking at has 4 beds upstairs then 2 downstairs. I would live in downstairs while renting the 4 bedrooms upstairs. Looking at the comparable rents I think I could make a whole lot more if I rented room by room. My general question is has anyone rented out room by room before? What are some pros vs cons versus just rented out the entire 4 bed unit as one?

Thanks I appreciate it!
