Which adjustable-rate mortgage holders are affected?
Only a small group. To qualify, you need to have received your loan sometime between Jan. 1, 2005 and July 31, 2007, and you need to be facing a reset of your interest rate sometime between Jan. 1, 2008 and July 31, 2010. If you're within this range, you may be eligible to have your interest rate frozen, so you can keep your current, lower rate for five years.
Who qualifies within that range?
The bailout is really designed for homeowners who could run into trouble if their mortgage payments are raised sharply and face the prospect of losing their homes. If you're well enough off that you can afford the higher mortgage payments after a reset, you won't qualify. And if you're in bad enough shape that you can't handle the current low interest rate, you won't qualify. For example, if you've already fallen behind on your mortgage payments, you're not eligible for the rate freeze.
