Vendor owned Greenacre, a tract of land, in fee simple. Vendor entered into a valid written agreement with Purchaser under which Vendor agreed to sell and Purchaser agreed to buy Greenacre by installment purchase. The contract stipulated that Vendor would deliver to Purchaser, upon the payment of the last installment due, "a warranty deed sufficient to convey the fee simple." The contract contained no other provision that could be construed as referring to title. Purchaser entered into possession of Greenacre. After making 10 of the 300 installment payments obligated under the contract, Purchaser discovered that there was outstanding a valid and enforceable mortgage on Greenacre, securing the payment of a debt in the amount of 25% of the purchase price Purchaser had agreed to pay. There was no evidence that Vendor had ever been late in payments due under the mortgage and there was no evidence of any danger of insolvency of Vendor. The value of Greenacre now is four times the amount due on the debt secured by the mortgage. Purchaser quit possession of Greenacre and demanded that Vendor repay the amounts Purchaser had paid under the contract. After Vendor refused the demand, Purchaser brought an appropriate action against Vendor to recover damages for Vendor's alleged breach of the contract. In such action, should damages be awarded to Purchaser? 
No, because the time for Vendor to deliver marketable title has not arrived.  No, because Purchaser assumed the risk by taking possession.  Yes, because in the absence of a contrary express agreement, an obligation to convey marketable title is implied.  Yes, because the risk of loss assumed by Purchaser in taking possession relates only to physical loss.
