tax lien certificates Problem Help!

[Maximo Pichardo]

I need some professional advise on the subject of tax lien certificates / Trust.
I been buying TLC for about 2 years now, however I just came across a deal with some good potential. I found a 20 acre prime land in Florida with an ASSESSED VALUE of 218K. This is what I know so far about the property:
• The land has been in the family for over 50 years
• The land is under a trust and the person in-charge is in California and there are rumors that the person charge with the trust is possibly dead.
• A person living on property in mobile home claims to be heirs to the trust with 3 other brothers.
• The property has no mortgage, free and clear
• Outstanding taxes paid by other tax lien investors total about 12K
My thought was to be creative with the deal. If I could find the person charge of the trust (which is the most difficult thing to do now) I would like to pay the tax lien for all three years that total 12K. Offer his the 12K as a down payment to the land and make a low offer, then owner finance the rest.
Take the 20 acres and sell them into pieces which should not be too difficult to do considering the prime location.
My question –If the person in charge of the trust is dead whom do I make a legal offer? Paying off the 12k lien money is easy, but how can I take possession of the property or title if the front line person of the trust is nowhere to be found. I know I have a really good deal before me, but I don’t know how to make it happen. Can anyone offer any advise?
