400 bucks for rent is pretty easy man. Probably just helping him out with taxes on the place if it's paid off or chipping in on the mortgage if it isn't (depending on the where of course). I mean you should want to help him out with that for allowing you to live pretty easy. I had to pay my old man 800 a month to stay in the basement when I got out of the Navy and was looking for a job and place of my own when I was 22 and it was only like 3 months total. 18 years ago when 800 went a lot further. But at the sametime I liked helping him out.
