Bob's mother sold her home to Mr. Walker, a kindly gentleman and avid gardener, who said he noticed her fabulous fruit trees on his Sunday stroll and decided to knock on her door to see if she would sell her property to him. Bob's mother thought the price seemed reasonable and signed the contract, without concern for her hearing and seeing difficulties given her extreme age. Bob has since found out that Mr. Walker was a real estate sales licensee, who bought a row of houses that Sunday with the intent of building a condominium complex on the property. No fruit trees will remain standing. And, after commissioning an independent appraisal, Bob now discovers that the price paid was less than two-thirds of the market value at the time of sale. Can Bob's mother have the sale set aside? Discuss the option(s) available to her. (7 marks)
