<prompt> Human: Hello PF,A quick background: I currently have a 4 bedroom house and I rent out one of the rooms to a good friend. He has free access to the kitchen and a pantry for food storage. Everything is good with our living situation and there is very little drama. He currently pays me 625.00 a month which includes utilities, internet, etc.Since he is taking another job that requires him to fly out frequently, he asked me to lower the rent. Tentatively, he will be flying out Sunday night and back on Thursday night. What should I consider as fair rent? Thanks in advance for the advice!Assistant: I would take his rate for a month and multiply by 12, divide by 52, divide by 7, then multiply by the number of days hell be there per week, then multiply by 52, then divide by 12 for a monthly rate.Eta: I get 268 per month, based on him being there three days a week, down from seven. Human: I initially thought about that as well. I also considered that the space that is being occupied while he is away.  <response>: This isnt how rent works.Your friend has no idea how rent works. Your friend still has his stuff in his room when he isnt there and you cant rent it out.
