Failed to recognize 5 weeks ahead of time that the closing date was during a holiday until the week before. Was off on closing funds by $3000. Was unable to work with the bank to get a wire to go through and called me AFTER the Fed Reserve had closed and expected me to solve the issue (I notified them that I sent the wire 30 hours earlier). Between the bank and title company they cost me $6000 more due to closing and bank mistakes, not to mention the hours it took to rearrange resources.
