What is the catch with Georgia Redeemable Deeds??

[Ryan Cooper]

I'm looking at a list of 25 properties, most of them in really good condition.

Referencing this site below, if a property is worth 100k, than I pay 50k to the tax assessors office.  

Scenario 1:  The owner pays me my 50k back and 20% on top to make it 60k.  That is an amazing return.

Scenario 2: The owner doesn't pay the taxes within 12 months and the property is mine and I start the foreclosure process.

What am I missing?  Why would any of these tax deeds still be available?
