i bought property at tax sale auction in Dekalb county Georgia, over 12 months ago, now i am doing barment, i published ad news paper, i sent 30 days notices to ex owners and all parties might have interest, and the property now it empty / unoccupied.

my question is: if 30 days notice expired and no body redeemed, can i enter the property and start to fix / repair the property, and rent it??

or i must have to complete quiet title from court judge order to to enter the property for fix / repair and rent it??

thanks
