[[[[......wouldn't regular people buying owner occupied homes have this issue?....]]]]
The title company checks this for every buyer. So the regular people who are buying an owner occupied home are getting the sellers (and themselves) checked for liens and lawsuits.
The big problem with lawsuits affecting the sellers is that the courts can decide that the seller is divesting and hiding assets and the courts can actually order the sale reversed. Since the seller probably really is attempting to hide assets so that they can pretend they have no money to pay judgements, child support, outstanding debts, you, as the buyer, might find yourself holding the losing end of the stick.
Figure the odds that the seller will still have all the money you gave him, especially considering that he is in the process of hiding all his assets.
