A foreclosure suggestion
A mayor could appoint a Foreclosure Investigator. Announce that any person anywhere in the city who has received a notice of foreclosure or similar document should immediately call the city officer who will investigate all the paperwork to make certain that every aspect of the mortgage and the mortgage foreclosure comply with the law--at no expense to the homeowner.
There's a lively discussion in the comments there.
Thanks to Holden Lewis of Bankrate.com for pointing it out.
