<prompt> Human: So Im tired of renting and money going nowhere. I talked to my dad and after i graduate University this year i want to split a condo with my reliable friend of 10 years whos in IT and makes great stable money. We want to get a cheap condo and pay 20 downpayment. After that id like to live in it with my friend until we can pay it off. its expected payoff in 8 years. The whole reasoning behind this is so that in 8 years i rent it out metro area with train station is a gold mind IMO and gain passive income as the CO OWNER. my dad agreed to go in on it with me . We expect the 20 to be to the tune of 40k and he said he will put in 30 and i will put in 10k. What is a fair percentage that once the house is paid off, what of the rent income is his and what is mine ? If this belongs somewhere else let me know. Thanks !  <response>: This is a great way to lose money and a friendship, good luck!
