Thanks to her recent TV appearances everywhere from "Good Morning America" to "Oprah," she's been showered with checks from some 50,000 good-hearted donors so far. (The outpouring of generosity continues -- in the first 48 hours after this story first aired on 20/20, Mock says she received an additional $20,000 in donations).
Still more people across the country have volunteered their financial and legal expertise, and any other assistance the Foundation might need.
This generosity doesn't surprise Mock's family. Her husband Bruce told "20/20" that she has a long history of helping anyone she can, and even extends that spirit to rescuing stray animals. But her main goal is to help people keep their homes, she said.
"It doesn't take much," Mock said. "Sometimes just a few hundred dollars to repair a life."
And where does her motivation come from?
"It needs to be done," she said. "That's it."
