Abstract: Methods and systems for automatically estimating expenses related to property damage caused by at least one catastrophic event may include identifying properties in a geographic region, determining property values for the properties and a customized event loss vector format corresponding to preferences of a user (preferred event model vendor, particular financial perspective, property value scaling factor, etc.), and executing catastrophic event models for the catastrophic event(s) to generate an exposure data set representing estimated losses for each property. The methods and systems may include, for each property, determining an estimated amount of physical damage, calculating an equity position estimate and analyzing it to determine likelihood of mortgage default, and, where likely, calculating an estimated loss due to default. The exposure data set and the estimated loss may be formatted in the customized event loss vector format and added as a row of a loss matrix.
