WASHINGTON (AP) — U.S. homebuilders are growing a little less pessimistic about the depressed housing market after seeing more people say they might be open to buying a home this year.

The National Association of Home Builders/Wells Fargo builder sentiment index rose four points to 25 in January. That's the highest level since June 2007.

Even with the fourth straight increase, the general mood is dim. Any reading below 50 indicates negative sentiment about the housing market. The index hasn't reached 50 since April 2006, the peak of the housing boom.

The index is rising because builders are seeing a rise people shopping for a home — not because they are not seeing more sales. In fact, 2011 may end up being the worst year for new-home sales on records dating back half a century.

Builders are struggling to compete with foreclosures, which have forced down prices of previously occupied homes. And many people are finding it hard to qualify for loans or meet higher required down payments.

Low appraisals are scuttling some deals after contracts have been signed. As a result, some people who want to buy a new house are holding off because they can't sell their home.

Those in a position to buy are benefiting from lower prices and mortgage rates. The average rate on the 30-year fixed mortgage is at a record low 3.89 percent. Yet those factors have done little to boost home sales.

David Crowe, the builder group's chief economist, pointed to some regional pockets of strength. New Orleans, Pittsburgh and other smaller areas, in particular, have reported increased buying.

New homes make up a small portion of housing sales. But they have an outsize impact on the economy. The builder trade group says each new home built creates an average of three jobs for a year and generates about $90,000 in taxes.

Sentiment about current single-family home sales rose three points to 25, according to a separate gauge in the survey. Builders are also more optimistic about future sales.

The outlook improved across the country, rising nine points in the Northeast, five points in the West, two points in the South and one point in the Midwest.
