How do you clear a title on a manufactured home that is a Freddie Mack forclosure real estate sale?

The property was listed by a real estate company as a MFF home on 4.5 acres. I placed a cash offer and got my offer verbally accepted. The next day I was informed by my agent that the seller agent was informed by Freddie Mack that there was no title on the MFF home and was being sold without a title. They are not allowing time to get the title cleared up and I had to sign an addemdum to purchase without title. Well I did a title search and found that there is a bank lien on the title. How do I get clear title? I did a home inspection and have to make a decision right away before the 10 days is up. I already agreed to buy the home without a title (but I just recently found that it still shows a lien) and thought I could get the title and then do an affidavit of affixture. But the bank still would have to release the lien from the title and I cant get any answeres from the bank. I have talked to the assett manager, credit department etc. What should I do, I am running out of time?
