Asking on behalf of my friend. She owns a condo and now want to rent a single room to a person. But haven't sign anything, haven't got deposit from that person. Yet that person requested if she can pay the rent by end of month instead of early of month. My friend seems desperate to rent it out as she's currently jobless and planning to do own business. So she has to juggle both sides. What is your advice or experience on this?

Edit: The person just gave her deposit 1 month. Agreement not yet sign. I should advise her to add in some clause to protect herself?
