Bruce and Karen Gershman (defendants) signed a contract to sell their condominium to Summit House Company (Summit) (plaintiff). Summit sued to terminate the contract. The district court awarded the Gershmans specific performance, requiring Summit to pay approximately $107,000. Summit did not pay the judgment. The Gershmans levied execution on the contract and bought Summit’s interest at a sheriff’s sale for approximately $73,000. Summit did not bid at the sheriff’s sale. Summit filed a motion for a judgment that the sale to the Gershmans satisfied the prior judgment against Summit. The district court denied the motion, finding Summit owed the Gershmans approximately $34,000, the difference between the sale price and the judgment. Summit appealed.
