If you were to close escrow on a home and find out after the fact that there was an outstanding lien, you would immediately make a claim with the title company who insured the loan and title transfer. They will be obligated to clear the lien or rescind the sale and refund all of your costs, down payment, fees, etc.
Title companies are typically very thorough in their chain of title searches including judgments, liens and other recorded or known instruments that could cloud title for this same reason.
Sorry to hear about all of your difficulties in obtaining accurate or reliable information from those who are licensed and sworn to be honest, ethical and responsible.
Best to you, Diane Wheatley, Broker
as 'normal sellers'.
Banks do not have to provide most of the standard disclosures to buyers.
If they choose to sell a 'problem property' they have the legal staff and deep pockets
to prevail should you be foolish enough to waste your money in court.
