sale that fell apart? We were required by our mortgage company to sign a promissory note as a condition to a short sale settlement. However, the buyer withdrew at the walk through right before settlement occurred. Since the promissory note was as a condition to settlement, but the settlement did not then occur, should we still do something about that signed promissory note, or it is null and void already without any actions on our part since it was a condition to the short sale settlement? The house is in Virginia. We live in Texas now. Thanks for any info!
