Question about mailiing list criteria

[RJ Browning]

When pulling my absentee lists I notice that there are alot of 100% equity results, Im wondering if the mortgage information just isn't available on most of these properties and therefore this value is a sort of default in that event. I realize that I can't cull out the 100% equity as there may be some true free and clear properties in there. What is everyone's experience with the accuracy of the equity percentage. Im assuming 99% down would be fairly accurate as that would be a sign that there is a mortgage reported and therefore the 100% equity default isnt in play. Just curious
