<prompt> Human: I have a small apartment that I am moving out from soon. I planned to get some tenants so I can get some money back from my investment The price of the apartment dropped recently and I also bought an AC and new fridge recently.My wife said her sister my sister in law would like to move in with her boyfriend. My sister in law is almost like a real sister to me and her boyfriend is a good friend so I made them a discount they should pay only 70 of the rent. I think they were happy with this offer because they know the prices very well. Also they pay more for a worse apartment at the moment.Some friends of mine told me I was greedy for asking money from them because its my sister in law after all, so I am unsure now. The thing is that I dont necessarily really need that rent money and my sister in law has a low paying job, however I would like to get some money back at least for the fridge and AC :. Also why would I pay for somebody elses rent? I could get real tenants instead, if I wanted.Am I too greedy? Should I stop asking money for rent or lower the amount? Or maybe ask for rent only for one year? How should I do it?  <response>: You shouldnt charge your family! So which family members are you letting live at your place for free then?
