I see dead people

[Corey Scott]

Sorry for the morbid title, but it got your attention, didn't it? Well here my situation...

I am in touch with someone that calls himself the personal representative of the owner of record who has been deceased for 7 years. It is behind on taxes for all 7 of those years. I want to buy the house. Who do I make the contract out to? Is the personal representitive the executor? What does this person have to present giving them the right to sell this house to me? Anything else I should know about this situation?

Also, the house is in Florida and the personal representative is out of state.
