There is obviously a formal lease, and we also supplement with a room mate agreement which outlines the more specific things like overnight guests and expectations in dispute resolutions/ cleaning/ care for the home and appliances, etc.I haven't received one formal "LL request" email yet, other than a formal 30 day notice in the event of a move out, which is usually after they've come talked to me in person about it to begin with. if there's an issue, it tends to be pretty limited to "hey, we have this shower rod falling off"... which im usually here to deal with (and tbh most of the time they like to fix it up with me), and it doesnt need to turn into a big thing. as for keys, i have the house on a yale smart lock, so 'handing over keys' is just official move out, walkthrough of the room for damages, and then I can delete their access code and access to the smart home systems without having to re-key the house.
