Problems buying bank-owned condos with liens

My fiance and I are in the process of buying a condo in Florida.  We have been nearly approved for quite some time but have been waiting for the condo association president to send us the liability insurance information (he is not located in this state), his secretary (she is located here) has no idea who it is and it was left out of the master insurance when it was initially sent. The Condo association is made up of three people, The President, the VP and the secretary. 

This is a bank owned property--with a lien on it and the bank is paying the lien BUT that is not our business, that is the bank and the HOA (lien is to the HOA). Our Real Estate agent has called the HOA President multiple times because he is apparently the only person with the liability insurance information and he has demanded payment for the lien from her, hung up on her, and acted completely irrational and non-professional. She said first he will say he'll get this done immediately then demand the lien payment, start laughing and hang up, he will then call her back and start the process over, saying if we do not pay the lien we won't get the liability insurance (He has done this to us as well, when we have called). Is there anything we can do?

I am afraid this man is not of sound mind and we have no control over the bank paying the lien, they will not pay the lien before this man does his job, and who is to say he even sends it if they pay it before he sends the information?

We need to move out of our apartment, we have no more options. We've been ready for at least a month--packed, even bought new kitchen appliances because we had a final closing date. So this needs to be done quickly. I hope you can help.
