<prompt> Human: Hi all - Background: - Me 26F dating him 28M for 2 years. - I purchased the house 3 years ago. - We both see this going towards marriage, eventually, but not for at least 2 more years. - Location: Philadelphia Financial Details: - My annual income: 93k bonus around 10 - His annual income: 85k bonus around 10 - Mortgage: 850mo 150 taxes and insurance.- Payment: I pay. 1,350mo taxes and insurance as I am trying to pay it off sooner than 30 years. - Cost to rent comparable house: 1,300 he rents a near identical floor plan, but less upgraded, home in the same neighborhood for this currently. Recently my boyfriend and I have been discussing moving in together when his lease is up at the end of April. I am totally on board with the idea, but am unsure how much to charge him in rent, and what sort of contract we should draw up for me to protect myself should things go south. Im thinking charging him half of what he pays now 650mo and splitting utilities, but keeping the taxinsurancemaintenancerepair costs as my expense until we are actually taking concrete steps towards marriage.What do you guys think? Especially do you have any examples of contracts we could use in this situation. He knows there will be a contract involved and that he will not be building equity in the house during this period, so I dont need advice on that conversation thank goodness.  <response>: I mean, 5050 seems like a pretty fair deal
