But the deed of trust the buyer signed is in the public record (every Texas county of medium-to-large population has scanned land records online) and has the amount of the mortgage issued on its front page so that gets you close.  That goes double if the form has an FHA case number at the top because it usually means the deed of trust is within 5% of the purchase price.<p>No, not all of the time, but very often enough to make it useful for social engineering.
