The idea is to set aside $1.5 billion in foreclosure initiatives for homeowners in Nevada, Michigan, Arizona, California and Florida. All have seen at least 20% declines in home values in the past year.

So far, so good. The $1.5 billion is part of Obama’s larger $50 billion Home Affordable Modification Program and will be used to create an “innovation fund” that state agencies can tap for various efforts to reduce foreclosures they deem “preventable.”

Some of those plans include helping homeowners going through unemployment, or simply underwater on their mortage, or even those with multiple mortgages and home equity lines of credit. In other words, people who are in a world of hurt and could use the money.

Here’s where the problem comes in. The treasury estimates there are at least 1.5 million homeowners in these five states that meet the broad criteria set out above. It further estimates the cost of modifying their loans at around $12,000 each.

Let’s do the math, shall we? At 12k a pop, $1.5 billion will only provide help for around 125,000 homeowners ($12,000 x 125,000 = $1.5 billion).

125,000 homeowners will surely appreciate the help, but that is a far cry from 1.5 million that are desperately in need of help.

To be fair, Obama has acknowledged that not everyone will be helped under this latest plan – nor is it necessarily advisable that everyone who took out a ridiculous loan should be allowed to get it modified.

“I’ve got to again repeat — government can’t stop every foreclosure,” said the President. “There’s not enough money in the Treasury to stop every foreclosure.”

Of course, let’s hope that the modifications actually make it to the people who need them most and not to simply irresponsible borrowers who helped create the collapse and have managed to find loopholes to avail themselves of the bailout.
