Need housing for Raj's brother

With no one else able to do so, I've been paying all of Raj's disabled brother's expenses for the past 3 years, using the proceeds of their parents' estate. The terrible real estate market, coupled with bankrupt/depressed investments, has finally caught up with his growing needs and expenses. I used some of the kids' college savings to pay his mortgage & bills March 1, and have shared the news with him. He's alternately sad/angry/suicidal, and has no one to blame, so it's falling to Raj and me. The immediate need is housing for him, since I'm guessing we'll face foreclosure on the house he's in.
