Life-of-Loan Tracking - A service that assures up-to-date flood determination data over the life of a mortgage. If a flood determination is purchased with life-of-loan tracking, then once the initial determination is issued, the flood zone determination provider will monitor for any flood map revisions-including Letters of Map Amendment or Letters of Map Revision-that might change the structure's insurance requirements. Besides changes in flood zone status, life-of-loan tracking should also monitor for any changes in community, community participation status, or CRBS/OPA status since any changes in these areas may also affect the mandatory purchase of flood insurance requirement for a property.
