Finding a plat map to Match w/ Legal Land Description for Auction

[Brandon Lancaster]

Currently in an Online County Tax Foreclosure Auction 

I Cannnot figure out how to FIND THE CORRECT "PLAT MAP"(?) for a Specific Area, So I can use the Countys "Legal land Description" ( Put 2 and 2 Togethor) And Make sure i know what im puchasing.

(they make it clear you are not purchasing the Address Given )

You are Purchasing a Parcel I.D # & Legal Land Description.

I Simply Cannot Find the maps to Use with the Land Description..  (you'd think they'd be available online since its an Online Auction with 1000s of Properties.)  

Thank you for ANY help with this.
