<prompt> Human: I have both a financial and moral question here. A friend of a friend really needs a place to rent short-term 2-3 months. I have a room in my house that I can rent, though its somewhat of an inconvenience for me I like having my own place.If I do this, its mostly as a favor, but I also dont want to slighted in this arrangement. I see year-long room rentals in my area typically get 500mo. What can I fairly ask for for the 2-3 months they will need it? I dont want to rip this person off, but it also seems like collecting 1-1.5k at the expense of giving up the quality of having a place to myself seems unfair to me. Any suggestions?  <response>: I dont want to help set the initial rent for your friend, but here is my friend-rent-policy that might be helpful. Rent starts at xxx for first two months. Month three rent goes up 100. Month four an additional 100 etc. no limit. Stay as long as you like. Ive done it twice.
