The Schlemeyers purchased a frame apartment house and discovered shortly after the purchase that there was substantial termite infestation. They undertook some of the steps suggested by a specialist in pest control but did not take all the measures he indicated would be necessary to ensure success. Six years later, the Schlemeyers sold the apartment house to Fred Obde but did not advise him of the termite condition. When Obde later discovered the termite infestation, he brought a lawsuit for damages against the Schlemeyers, contending that they had fraudulently concealed the infestation from him when they had been under a duty to disclose it. Can Obde recover?
