Looking for good advice on purchasing Tax Deeds

[DuJuan Paxton]

Hello BP!

Question:  

I am considering purchasing 5 Tax Deeds as a package deal from another investor.  These properties are all vacant lots in very desirable areas in Fulton and DeKalb Counties in Georgia.  Since I've never purchased a Tax Deed, I would appreciate any advice from some of the more experienced investors that have come across deals like this.  What are somethings I need to consider while doing my due diligence?  Thanks for any nuggets you can provide!
