All-Mart Discount Stores Corporation, contracts to buy ten acres from Suburban Enterprises, Inc., as a site for a new store. The contract calls for a "warranty deed" without specifying the covenants to be included in the deed, or any particular guaranties. The title examination uncovers a zoning law that would affect All-Mart's proposed use of the land. According to a survey that All-mart commissions, one corner of an adjacent, enclosed parking lot is on part of the property that Suburban is attempting to convey. Can All-Mart avoid the contract? If so, on what basis? If not, why not?
