Do I have to be a Lawyer or Private Investigator to work with Florida Tax Deed Surplus?

No to both.  A lot of people are under the impression that you do. However, that is pertaining ONLY to unclaimed property being held by the STATE unclaimed property division shown on https://www.fltreasurehunt.gov

Tax Deed Surplus is held by the individual counties and are governed by their own laws. You do not even have to have a business license (but we suggest you do).
