Since the home auction, Marilyn and Tracy have become close friends, and Marilyn has been inspired to help save more homes through her organization, Foreclosure Angels.

So far, Marilyn says she's been able to help four other homeowners and has received more than 10,000 requests for assistance. "Most of the people, they only need maybe $600 to maybe $2,000 to keep their house," she says. "They don't need a lot."

These days, Tracy says she's financially stable, employed and forever grateful for the kindness of strangers.
