<prompt> Human: Im a medical resident and Im living in a house with a fellow resident, who happens to be my landlord. Things were going fine until recently when some strange issues started to pop up. We do not have any formal lease or anything like that. All the paperwork that is there is an email talking about what the prices and expectations of rent are which is really If its us 2, its X. If we add another resident emphasis mine, itll be Y. Utilities will be 2 or 3 way. That arrangement was fine with me. It turned out to be just us two. Now as it turns out, with the spare bedrooms in the home, my landlord has begun using them for Airbnb. This is quite different than what I expected in having a fellow physician living in the domicile. I guess it doesnt really matter, but I just feel weird about it particularly since this isnt something that was discussed with me before I moved in. I just find it really odd and kind of weird sharing my space with some random person. My landlord doesnt seem to mind as much, but I guess they had the idea in the back of their head the whole time. My current rent is far above what Im willing to pay with an airbnb arrangement in my house, but I just dont know how to even bring this topic up. Im kind of scared and am hoping somebody can give advice on how to renegotiate my rent down as well as get a written contract, something that has been promised since June but not done yet and that was before the airbnb thing. Next, I am bringing my dog back with me when I return currently Im away at a conference. My landlord is telling me to get dog bite insurance which is something I havent ever heard about. I asked some of my friends who have dogs and also rent and they have never heard of this either. I find this to be really weird, particularly since Ive raised this dog since she was a puppy and she is not a violent dog at all. In fact if a criminal were to enter she would not defend us at all! lol. Does anybody have advice on this topic? I am open to all suggestions. I really appreciate everybodys time. Thank you all.  <response>: Long post, simple advise from a landlord. Cordially leave now while in good standing and get a place with a proper lease. Nothing good will come of these flexible boundaries that can be changed on a whim.
