<prompt> Human: My buddy bought a house, wants me to rent one of the rooms so he can save a little on bit mortgage. We split all utility bills down the middle, and because its his house and he makes much more money than I do, household repairs are covered by him.Theres no lease, Id just pay him whatever we agreed upon for rent on the 1st of each month, and give him money when utility bills came in. This all seems fairly simple to me, but Ive never lived somewhere where I havent had to sign a lease, is there something in this situation Im overlooking that could royally fuck me later?Any advice given a living situation like this would be greatly appreciated.  <response>: In practice, nothing much... Its good to set expectations in a lease, but its more an issue for your friend not to have a lease, you are in less of a bad situation. You have implied tenant rights after living somewhere for 30 days.
