How so? How does that affect you? He can't refi the house. So be it. Then it will have go to a short sale and he'll have to give you half of the proceeds plus the $3,000 that he owes you.
Then you'll have it spelled out through your L that the house will need to be put up for a short sale if he cannot refi the house within the next 30-day period.
Just wait...just wait...I won't be surprised if the OW's father offers to take on the house's deed/mortgage.
