Plan To Sell Within 5 Years? Consider An Adjustable-Rate Mortgage.

Which is better -- a fixed-rate mortgage or an adjustable-rate mortgage? It's a common question among home buyers and refinancing households in Georgia.

The answer? It depends. 

Fixed-rate mortgages give the certainty of a known, unchanging principal + interest payment for the life of the loan. This can help you with budget-setting and financial planning. Some homeowners say fixed-rate loans they offer "peace of mind".

Adjustable-rate mortgages do not.

After a pre-determined, introductory number of years, the initial interest rate on the note -- sometimes called a "teaser rate" -- moves up or down, depending on the existing market conditions. It then adjust again every 6 or 12 months thereafter until the loan is paid in full.

ARMs can adjust higher or lower so they are necessarily unpredictable long-term. However, if you can be comfortable with uncertainty like that, you're often rewarded with a very low initial interest rate -- much lower than a comparable fixed rate loan, anyway.

Freddie Mac's weekly mortgage survey highlights this point.

The interest rate gap between fixed-rate mortgages and adjustable-rate mortgages is growing. It peaked 2 weeks ago, but remains huge at 1.16 percentage points.

On a $200,000 home loan, this 1.16 FRM/ARM spread yields a monthly principal + interest payment difference of $136, or $8,160 over 5 years, the typical initial teaser rate period.

Savings like that can be compelling and may push you toward an adjustable rate loan.

You might also consider a 5-year ARM over a fixed-rate loan if any of these scenarios apply:

1. You're buying a new home with the intent to sell it within 5 years
2. You're currently financed with a 30-year fixed mortgage and have plans to sell the home within 5 years
3. You're interested in low payments, and are comfortable with longer-term payment uncertainty

Furthermore, homeowners whose existing ARMs are due for adjustment might want to refinance into a brand new ARM, if only to push the teaser rate period farther into the future.

Before choosing ARM over fixed, though, make sure you speak with your loan officer about how adjustable rate mortgages work, and their near- and long-term risks. The payment savings may be tempting, but with an ARM, the payments are never permanent.

Adjustable Rate Mortgages Adjusting To 3.000 Percent Right Now

If your ARM is due to adjust this spring, your best move may be to allow it. Don't rush to refinance -- your rate may be adjusting lower.

It's because of how adjusted mortgage rates are calculated.

First, let's look at the lifecycle of a conventional, adjustable rate mortgage:

1. There's a "starter period" of several years in which the interest rate remains fixed.
2. There's an initial adjustment to rate after the starter period. This is called the "first adjustment".
3. There's a subsequent adjustment until the loan's term expires. The adjustment is usually annual.

The starter period will vary from 1 to 10 years, but once that timeframe ends, and the first adjustment occurs, conventional ARMs enter a lifecycle phase that is common among all ARMs -- regular rate adjustments based on some pre-set formula until the loan is paid in full, and retired.

For conventional ARMs adjusting in 2011, that formula is most commonly defined as:

(12-Month LIBOR) + (2.250 Percent) = (Adjusted Mortgage Rate)

LIBOR is an acronym for London Interbank Offered Rate. It's the rate at which banks borrow money from each other. It's also the variable portion of the adjustable mortgage rate equation. The corresponding constant is typically 2.25%.

Since March 2010, LIBOR has been low and, as a result, adjusting mortgage rates have been low, too.

In 2009, 5-year ARMs adjusted to 6 percent or higher. Today, they're adjusting near 3.000 percent.

That's a big shift. 

Therefore, strictly based on mathematics, letting your ARM adjust this year could be smarter than refinancing it. You may get yourself a lower rate.

Either way, talk to your loan officer. With mortgage rates still near historical lows, Atlanta homeowners have interesting options. Just don't wait too long. LIBOR -- and mortgage rates in general -- are known to change quickly.
