If he isn't joking, we have to check he value of his house. Example: what location is he in, what continent... ETC
Also these do seem slightly joking to have a house or a paycheck as colateral and he could lose these if he isn't if he is not careful.
I was thinking about this to (the value of the house)... A while ago, it made the newspapers in my country that there were some houses (i think in Detroit) being sold for $100-$1000. You couldn't really call them houses anymore tough, just 4 walls and part of a roof.
In this case, such a house could be valid collateral for a 1.2
BTC loan i suppose (eventough i would never take such collateral).
