With mortgage rates incredibly affordable and the economy emerging from a serious recession, there has never been a better or more urgent time to refinance a home.

Reducing your payments as much as possible will allow you to save money now, and save your home from foreclosure if you're laid off a few months from now.

Our 6 smart moves can help you make the most of this opportunity.

Smart move 1. Shop around for the best deal.

For most borrowers, that's the lowest interest rate you can find on a 30-year, fixed-rate loan without having to pay points or more than $1,000 in fees.

(Fixed-rate loans are so cheap, there's no reason to even consider an adjustable-rate mortgage.)

The best place to start is the Internet. Our extensive database of mortgage rates, for example, allows you to compare loans being offered by dozens of lenders in your area.

Then ask friends and family members who've just refinanced about the bank or mortgage company they used. And don't ignore local credit unions. They often charge less than commercial banks.

To locate one near you, go to findacreditunion.com and then check their mortgage rates.

Smart move 2. Learn from a rejection.

If you're rejected -- and almost half of all applicants are -- you'll receive an "adverse action" letter stating why you were turned down.

Don't get mad -- get busy.

If the appraised value on your home is too low to warrant the size of the loan you need, dig up the cash to make it work or look for other options (see below).

If your problem is a low credit score, you can fix that. To get the best rate you'll need a score of 740 or better. Our 7 smart moves to improve your credit score can help.

Above all, keep shopping. A rejection from one lender does not mean you'll be rejected by all lenders.

Smart move 3. Not enough equity? Don't give up.

Most lenders won't refinance your mortgage unless you have 20% equity in your home -- a tough criterion to meet if you live in an area where property values have fallen 20% or more.

(To calculate your equity percentage: Subtract the balance on your existing mortgage from your home's current value and divide the difference by the current value.)

But you can overcome that problem by applying for one of the federal government's three big loan programs. You'll need:

• Just 5% equity to qualify for an FHA loan.
• Zero equity to qualify for a VA loan.
• Less than zero equity -- you can actually owe more than your home is worth -- and still qualify for President Obama's Home Affordable Refinance program.

Smart move 4. Refinance anytime you can lower your mortgage rate by a percentage point or more.

This is a good rule of thumb to follow when deciding whether you've found a worthwhile deal:

Reduce your interest rate by 1 percentage point and you'll reduce your monthly payments by $65 a month for every $100,000 you borrow.

Our refinancing calculator can help you evaluate any offer more precisely.

It will calculate exactly how much your payment will decrease and how long it will take to recoup any fees and closing costs. A year or less is ideal. Two years or more is too long and indicates the fees are too high for the interest rate you're being offered.

Smart move 5. This isn't the time for a cash-out refinancing.

The goal of refinancing in a bad economy should be to lower your monthly payments as much as possible, so that you can keep writing those mortgage checks even if your pay is cut or you get laid off.

That means you want to borrow as little as you can, which is usually the amount you need to repay your existing mortgage.

In good times, it can make a lot of sense to borrow an extra $20,000 or $30,000 with a low-cost mortgage and use that money to repay credit card bills or other high-cost debt.

But not right now. With nearly 2 million families expected to lose their homes to foreclosure this year, you've got to focus on getting a payment you can make, no matter what.

Smart move 6. Don't pay an application fee.

Being charged for the privilege of applying for a loan is a big red flag.

Lenders who do this are often taking more applications than they can process -- or fund -- just to profit from the application fees.

Reputable lenders don't expect to be paid until closing.
