After McBee and Nance began dating, McBee had financial difficulties, and Nance gave her various cash loans. McBee signed a promissory note for $15,000, secured by a deed of trust on her house. After she failed to make payments, Nance foreclosed on the house. McBee then sued, arguing the consideration was inadequate; that it should be the same as the amount of the note. Is this correct? Explain.
