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.
