Yes, such a judgement can result in a lien being filed on your property. It doesn't matter what the present creditor paid for the account. The fact is that "junk debt collectors" as they are known, pay for many accounts on which they will never collect. So if they pay pennies on the dollar and happen to collect on just a few accounts, that's their profit; it perfectly permissable under the law (as long as they follow legal collections practices).That having been said, such a lien typically does not result in a property being sold. Rather, the lien remains on the property until it is either refinanced or sold. The creditor will then be paid off out of the proceeds (however interest will accrue until then).
