An assignment is the correct recorded instrument when the ownership of a mortgage loan is transferred from one lender to another. The local bank is not releasing the mortgage, so “satisfaction” is wrong. It is also not changing lien priority, so “subordination” is wrong. A reconveyance is commonly associated with deed-of-trust jurisdictions, not the ordinary Pennsylvania mortgage-transfer concept tested here. For title purposes, the recorded assignment gives record notice that the national bank is now the mortgage holder or assignee. This falls directly under the Pennsylvania Title Insurance outline’s clearing-title principles, which specifically include releases, assignments, subordinations, and affidavits as tools used to resolve title matters.
