Adjustable-Rate Mortgages Starting To Adjust Higher

For the first time in a year, homeowners with adjusting mortgages are facing rising mortgage rates. The interest rate by which many adjustable-rate mortgages adjust has climbed to its highest level since September 2010, and looks poised to reach higher.

This is because of the formula by which adjustable-rate mortgage adjust.

Each year, when due for a reset, an adjustable-rate mortgage's rate changes to the sum of fixed number known as a "margin", and a variable figure known as an "index". For conforming mortgages, the margin is typically set to 2.250 percent; the index is often equal to the 12-month LIBOR.

LIBOR stands for the London Interbank Offered Rate. It's a rate at which banks lend to each other overnight.

Expressed as a math formula, the adjusting ARM formula reads :

(New Mortgage Rate) = (2.250 percent) + (Current 1-Year LIBOR)

LIBOR has been rising lately, which explains why ARMs are adjusting higher as compared to earlier this year. There has been considerable stress on the financial sector and LIBOR reflects the uncertainty that bankers feel for the sector. 

LIBOR last spiked after the collapse of Lehman Brothers in 2008 amid global financial fears. Analysts expect LIBOR to rise into 2012 because of bubbling concerns in the Eurozone.

Despite LIBOR's rise, though, most adjusting, conforming ARMs are still resetting near 3 percent. For this reason, homeowners with ARMs in New York may want to consider letting their respective loans adjust with the market.

This is because an adjusting mortgage rate near 3 percent may be better than what's available with a "fresh loan" -- even as 5-year ARMs rates make new all-time lows. Unlike a straight refinance to lower rates, an adjusting loan requires no closing costs, requires no appraisal, and requires no verifications.

So, if you have an adjustable-rate mortgage that's set to reset this season, don't rush to refinance it. Talk to your lender and uncover your options. Your best course of action may be to stay the course.

Your ARM Is Adjusting Lower. Is There A Downside To Letting It?

When adjustable-rate mortgages are on the verge of adjusting, a common concern among homeowners is that their mortgage rates will adjust higher.

Well, this year, because of the math of how ARMs adjust, homeowners in Brooklyn, NY and around the country are seeing that mortgage rates on ARMs can sometimes adjust lower, too.

Adjusting conforming mortgages are adjusting to as low as 3 percent.

As a quick review, here's the timeline for most conforming adjustable-rate mortgages:

1. There's a "starter period" in which the interest rate remains fixed. This can range from 1-10 years.
2. There's a rate change after the starter period. It's called the "first adjustment".
3. Subsequent, annual adjustments follow until the loan "ends". This is usually after Year 30.

The adjustments each year are based on a math formula that's included in the contract with your lender. It's surprisingly basic.  Each year, your new, adjusted mortgage rate is equal to the sum of some constant -- usually 2.25 percent -- and some variable.  The variable is most commonly equal to the 12-month LIBOR.

As a formula, the math looks like this:

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

LIBOR is an acronym standing for London Interbank Offered Rate. It's an interest rate at which banks borrow money from each other -- very similar to our Fed Funds Rate here in the United States. And also like our Fed Funds Rate, LIBOR has been low lately.

As a result, adjusting mortgage rates have been low, too.

In 2009, 5-year ARMs adjusted to 6 percent or higher. Today, ARMs are adjusting to 3.000%.

Based on the math, you may want to let your ARM adjust with the market year. Or, if you plan to keep your home long-term and have concerns about adjustments in 2011 and beyond, it may be a good time to open a new ARM.  The same forces that are driving down LIBOR and helping to keep mortgage rates low overall, too.

Consider talking to your loan officer and making a plan. With mortgage rates as low as they've been in history, most homeowners have options.  Just don't wait too long. LIBOR — and mortgage rates in general — are known to change quickly.
