Florida Tax Lien question

[Adam Harper]

Hi all, been reading about tax lien in Florida and was curious enough to go on the county tax collector to see what available. I saw quite a few available for purchase. Digging a bit deeper and noticed that all owners are out-of-state, or PO Box address, or companies. How do I find out the actual addresses of the properties? How do I find out if there are any other liens against the same properties? Greatly appreciated for any advice.
