The laws of South Carolina provide that in any real estate foreclosure proceeding a defendant against whom a personal judgment is taken or asked may within thirty days after the sale of the mortgaged property apply to the court for an order of appraisal. The statutory appraisal value as approved by the court would be substituted for the high bid and may decrease the amount of any deficiency owing in connection with the transaction. THE COMPANY HEREBY WAIVES AND RELINQUISHES THE STATUTORY APPRAISAL RIGHTS, WHICH MEANS THE HIGH BID AT THE JUDICIAL FORECLOSURE SALE WILL BE APPLIED TO THE DEBT REGARDLESS OF ANY APPRAISED VALUE OF THE MORTGAGED PROPERTY.
