With signs that a real estate recovery may be kicking into gear, a new survey shows a sharp increase in optimism among real estate professionals about the direction of home values.

A survey conducted by home valuation website HomeGain found that the number of real estate professionals who expect home values to increase has more than doubled over just one quarter. Thirty-seven percent of respondents surveyed so far in 2012 said they anticipate that home values will rise in the next six months, up from 15 percent in the fourth quarter of 2011.

“The trend has been staying the same or decreasing. And here it flipped for the first time,” HomeGain General Manager Louis Cammarosano told AOL Real Estate.

He added that since HomeGain began administering the survey in the second quarter of 2009, the percentage of respondents who have expressed a bullish outlook on the market has never risen above 25 percent, and, for much of the time, has sputtered around 15 percent.

The spike in optimism about home values follows recent reports that corroborate the view that the housing market is stabilizing. Home sales are trending upward and homebuilders are reportedly more optimistic than they’ve been in many years. Home prices continue to fall, but a number of industry observers say that price direction isn’t necessarily the most important bellwether of a recovery.

Budge Huskey, president and chief operating officer of Coldwell Banker Real Estate, says he sees confidence among real estate agents that he hasn’t observed since the housing meltdown. “What is consistently being represented out there today is that there is a sense of optimism in the real estate business that has not been seen in the last five to six years,” he told AOL Real Estate.

While cautioning that real estate agents “tend to always be optimists,” Huskey stressed that “this time it’s based on what we believe to be some clear trends.”

Prominent among the hopeful signs, Huskey says, is the state of the housing inventory, which had fallen to 2.3 million homes, or approximately a six-month supply of for-sale homes, as of January. That’s the lowest level of inventory since March 2005, according to the National Association of Realtors, which released the statistic.

Meanwhile, total home sales have risen by 13 percent in the last six months, according to Capital Economics. And while construction of new homes dropped marginally in February, they still were at the second-highest level since October 2008, the National Association of Homebuilders says.

A last sign, much ballyhooed by industry optimists, is the state of homebuilders’ confidence: The National Association of Home Builders sentiment index reached 28 in February and remained at that level in March. Not since 2007 have homebuilders expressed such confidence in the housing industry.

Despite sprouting green shoots in the market, home prices continue to slide, and even when they do eventually trend upward, many economists say, the increase will be gradual.

That fact has led some industry observers to call for a rethinking of what actually constitutes a housing recovery, and to avoid treating price movement as the all-important indicator of a recover.
