Georgia Tax Sale Question

[Aaron Millis]

Hi everyone. So I live near Georgia and am interested in investing in Tax Sales in GA counties. I know basically how everything works but I had an idea/question and I would appreciate the feedback.

So I know in GA once a property goes to tax sales for delinquent prop taxes that the owner must pay the winner whatever their bid was plus 20% within the year. So if someone's property was worth $100,000 and they only owed a couple hundred dollars in taxes, and it went to auction, it's possible and I imagine likely that someone is going to bid tens of thousands of dollars. Because why wouldn't they? They could get a great deal on a property or a great return on a nice chunk of money.

Assuming everything that I just said is accurate, my idea is to reach out to these people who owe money on taxes and are soon to have their property sent to auction, and find a way to construct a deal with them where I put a lien on their property-  pay their property taxes but still demand a certain interest rate or return back- and also make the time similar to Ga law or possibly shorter where if they don't pay me back the amount I can seize their property.

So an example is someone has a $100,000 property- owes $1,000 in delinquent taxes- Its going to auction soon- I step in and say I will pay their taxes but I want $5,000 with a year from now or I get the property.

So the idea is to make a good return on my investment while saving people from the bigger dogs just around the corner.

If this is possible how would I legally construct it? Who would I need to talk to?

I hope I worded this well enough for people to understand and thanks for any feedback.
