Low rates have done little to jolt the struggling housing market. Sales remain depressed, and home prices are still dropping in many markets.
High unemployment and declining wages have made it harder for many people to qualify for loans. Most of those who can afford to refinance already have.
The number of Americans who bought previously occupied homes fell in September and is on pace to match last year's dismal figures _ the worst in 13 years.

Many borrowers are unable to take advantage of the low rates because they can't meet banks' restrictive lending standards, or are unable to scrape together a down payment.
The low rates have caused a modest boom in refinancing, but that benefit might be wearing off. Most people who can afford to refinance have already locked in rates below 5 percent.
The Federal Reserve has been helped push rates lower by buying longer-dated Treasurys, such as 10-year Treasury notes. Mortgage rates tend to track the yield on the 10-year note. Buying by the Fed pulls the yield lower.
Rates have been below 5 percent for all but two weeks in the past year. Just five years ago they were closer to 6.5 percent.
