Since they placed it back on the market on Thursday there is always a chance another offer could come in. However, it doesn't sound like you have signed a cancellation on this one so one might be able to argue that you are still in play.
As long as there isn't another offer I would say you still have a good chance on this one. The last two times I have dealt with this, the original buyer (you) did get the house. It also depends on the relationship with the listing agent. Make sure this person knows you still want the house and are doing everything you can to get this done.
Good luck and stay on top of your lender.
