You might be looking in the wrong county. I had the same problem when I first starting looking, and still looking. Some of the newer streets and sales still don't show up. I'm posting what I have but I'm not sure if they will come out as a direct link. You might have to copy and paste it into your browser and then save it to favorites. Ive found most sales and resales are in Sumter and Lake county.
