Problem: Jack and Jill purchased a four-bedroom split-level from Mountain Homes, Inc. They had explained to Mountain's salesman that they intended to raise their children aged three and nine months, in their new home. The location seemed ideal, at the end of a cul-de-sac, and behind their back yard was the forty-acre estate of Daryl Pharr, a wealthy investor. The first Saturday night in their new home they were kept awake all night by loud music from the Pharr estate. They also smelled marijuana smoke wafting from the party through their children's windows. They soon learned that Pharr had a raucous party all night long every Saturday night and had for a long, long time. Jack and Jill consulted a lawyer. "If we'd known about Pharr's parties, we would never have bought this place," Jill wailed. What should their lawyer advise them?
