Poke your landloard about it ahead of time, you might be able to avoid late fees and missunderstandings about it. "I just started a new job and my paycheck is expected five days after rent is due, can we come to an agreement" is a perfectly fine way of doing things. If your new sugar daddie offers to pay the rent, you even get to keep it or, or pay early depending on what makes you feel better.
If theyre assholes about the whole thing, you know to not say shit if this comes up again. Let them be the ones counting on a check that doesnt show up on time.
