Intervening liens that would prevent the lender from having first lien priority can be addressed by subordination. A subordination agreement makes an otherwise prior or intervening lienholder agree that its lien will rank behind the insured mortgage. That clears the priority problem for loan-policy underwriting. “Waived to the lien” and “restricted to the lien” are not the correct title-clearing terms. Subrogation is different: it allows one party to step into another party’s priority position after paying a debt or claim; it is not the normal document used when an existing lienholder agrees to become junior. The Pennsylvania title outline expressly includes voluntary and involuntary liens, releases, assignments, subordinations, and title-clearing procedures.
