What liens/judgements can prevent the sale of a property in Texas

[Garnett Freeman II]

I am in negotiations to get a property under contract in DFW. House has an almost $60k tax lien on it. Seller is the daughter of deceased owner and doesn't seem too open to speaking on details of other possible encumbrances. A question to you professional investors: What other possible liens/judgements can prevent the sale besides debts, mortgage debts and mechanics liens? Can credit card debt be used to put a lien on a property?
