In McGregor v. Echols, 153 Ark. 128, 239 S.W. 736 (1922), the court wrote: "In actions against a vendee on a contract for the purchase of real estate, we had supposed it to be a well settled rule that when a party agreed to purchase real estate at a certain stipulated price and subsequently refuses to perform his contract, the loss in the bargain constitutes the measure of damages, and that is the difference between the price fixed in the contract and the salable value of the land at the time the contract was to be executed." (153 Ark. at 132, 239 S.W. at 736.)
