Definition of "Historical Scenario"
Andrew Karigan, Real Estate Agent
Karigan Residential
The assumption that the index value to which the interest rate on an ARM is tied follows the same pattern as in some prior historical period. In meeting their disclosure obligations in connection with ARMs, some lenders show how the mortgage payment would have changed on a mortgage originated some time in the past. That is not very useful. Showing how a mortgage originated now would change if the index followed a historical pattern would be useful, but nobody does it.
