AR 600-20 is very clear on this issue. It is a NOGO. Here is an extract of AR 600-20. I would strongly encourage you to read the entire paragraph as it pertain to Fraternization.

An officer cannot rent a room from an enlisted Soldier, or vice versa, if common areas, kitchen, living room, etc, are shared.
