How to determine if an auction property is free and clear?

[Terrence M Brannon]

Hello, I want to buy properties at the Broward County or Miami Dade auction websites. Both sites make it clear they do not insure the property is free of liens, mortgages and other encumbrances.

How do I make sure that upon purchasing the property that I am not subject to all sorts of hidden burdens that were formerly the responsibility of the previous owner?
