Tax Deeds Auction: Title Issue?

[Matt Smith]

I bought a land at a County Tax Deed Auction 1 year ago. I am about to sell it…but I need to have Title Insurance. I got the Title Prelim document and there are several items listed such as the tax liens from the unpaid property tax of course, but also some other items such as Abstracts of Judgment. Are those cleared out after I bought the land at a tax deed auction?
