Here's a look at the state of mortgage rates from Bankrate.com's weekly national survey of large banks and thrifts conducted Feb. 10, 2010.

Mortgages

Mortgage rates did not budge this week.

The average 30-year fixed-rate mortgage stood at 5.15 percent for the second straight week, and third week in the past four. A basis point is one-hundredth of a percentage point.

Meanwhile, this week's average 15-year fixed-rate -- a popular option for refinancing -- dropped 3 basis points, to 4.52 percent.

The average jumbo 30-year fixed fell 5 basis points, to 5.95 percent.

Adjustable-rate mortgages split this week. The one-year adjustable-rate mortgage dropped 3 basis points, to 4.89 percent. Meanwhile, the popular 5/1 ARM remained unchanged at 4.56 percent.

Mortgage applications fell a seasonally adjusted 1.2 percent when compared to a week earlier, according to the Mortgage Bankers Association. For the week ending Feb. 5, refinancing activity increased 1.4 percent, while applications for new purchase sank 7 percent.

In other mortgage-related news, some housing markets are showing early signs of a double-dip in price declines, according to the real estate Web site Zillow.com.

Many markets that had recorded a series of monthly price gains in 2009 -- including Atlanta, Baltimore, Boston, Denver, Minneapolis and Portland, Ore. -- saw values begin to fall again in December.

Overall, 29 of 143 markets nationwide recorded price-flattening or declines in December, after chalking up at least five consecutive months of price increases earlier in 2009.
