Thank you sooooo much guys for all your support!!
It was really helpful to bounce ideas with you all since it seemed that the situation was stalled due to his lack of cooperation.
As @Ned Carey said, I'm starting to get a handle on the situation. Today, I learned my lender (owner of the property) is going to finally take charge of the situation and file a petition to quiet the Title and got the Title commitment showing the defect. As @Tom Gimer said it involved a defect in the original tax sale foreclosure "Interested parties were not named in the Collector's deed recorded in the Books, though named in the Collector's deed and one as one person was named incorrectly".
Indeed, msy hand were tied without his cooperation. I did not know the specifics of the defect and could not supply the documentation to support my claim to the Title insurance.
He claimed, he could not write the letter or do anything, because he does not speak English (excuse!). That's the reason I wanted to help filing his claim, but he did not take my offer. Anyway, I filed my claim when I realized we would not do anything, but had difficulty getting documentation from him to support it.
The transaction was for business purposes. He lended the money under his LLC with the intention of adding value to the property, refinance the property to pay back the loans and then flip it later on ( it became a 2 year flip!)
Thank you again to all of you for your advise and support!
I'm hoping for smooth sealing now on....
