Jason saw a house and decided he really liked it and wanted to buy it. He met with Mary, the owner, and offered her $750,000. Mary said she wasn't sure she wanted to sell. Jason told her to think it over and call him by noon the next day. Mary called him the next afternoon and said she would sell the house if Jason provided $100,000 immediately and paid the remainder when he took possession in one month. Jason agreed and transferred $100,000 to Mary that day.

Two days later, Mary changed her mind and sent Jason a letter stating she would not give him possession in a month, and that she could never sell her house for only $750,000.

To succeed in an action for breach of contract, Jason must first establish an enforceable contract. Please assess the likelihood of Jason succeeding on this point. (8 marks)
