We had a similar situation - we were buying a foreclosure and were told it was delayed right after we rented out our condo. We planned to live with my inlaws for a week - it was looking like a month. Then the whole place fell through - turned out the bank hadn't foreclosed right (we lost about $1k on home inspection, etc.) and we had to start looking again - and there was even less out there. But we did find our house! We would up living with my in-laws 3.5 months, but we got a great house in a better location in the end. Just hang in there - I know it stinks!
