Researching properties before tax sale

[Calvin N.]

I will be attending another tax sale/auction next month and started checking out the properties listed for sale in my county. There are 9 properties scheduled. Of course, several will pay before then. Taxes on these properties range from $289.44 up to $1257.38. Not a lot of money but a change to make 20% here in Georgia (a hybrid/deed state with a 12 month right of redemption period) on the money.

What steps do others take in preparing to bid on the tax lien/deed sales? I have personally driven by all the properties, checked the tax records to see who paid the bill in past years and also checked the county records to see what the property sold for and when. What else should I consider before bidding?

The county tax commissioner's website claims all liens are erased once foreclosure is completed; this includes mortgages, liens, and federal tax liens. The foreclosure only happens after the 12 month right of redemption period ends. What else should I look for? Thanks for your replies.
