Thanks for all of your replies. I appreciate the responses, even if they were not quite what I expected!!

Perhaps I should be more clear: After 2 months, assuming he has a job, we are going to ask him to kick in for rent. My brother, as much as I like him, is extremely cheap. I'm quite certain that if we never asked him to pay a dime, he wouldn't...he'd probably think he'd died and gone to heaven and would live with us forever.

If he wants to find a place right away, then it's understandable that he would want to save, and I wouldn't begrudge him not paying for anything, but I'm pretty sure he will just hang out at our house for a while and I have neither the means nor the inclination to support another adult for longer than necessary.

We've actually lived with him before- right after college we all three rented a house together- and he ended up moving out and leaving Eric and I to pay for everything, which we didn't plan on. :/ So, I've already decided that's not happening again, and I want to be clear right from the start what our expectations are.
