Do I need a license to buy a tax lien certificate in GA?

[Ruth Utin]

I am new to investing and have a small pot of cash to start with. I want to start purchasing tax lien certificates in fulton county, GA and I overheard someone mention that a license was needed to buy tax lien certificates at the courthouse steps. I tried researching this but could not find any info to confirm this. Is it true that a license is needed? If so, does anyone know how to get around this?
