I think this is the website 'retiredguy" is referring to:
Record Search : Sumter County Property Appraiser
Once there, in the top bar, click on "Record Search/GIS Map" and enter your street address in the corresponding white box. Then click enter.
Another window opens. When your record displays, scroll down the page and find the sale date on the left side that corresponds to your purchase. Click on the red numbers in the "OR Book/Page" next to sale date. Another window opens. On the right side, in small type, find "View Document" That's the deed that Sumter County has for you. Good luck.
