Lower prices, discounts on mortgage rates and other incentives for home buyers yielded much stronger than expected orders for Toll Brothers Inc. (TOL) in the fiscal third quarter ended July 31.

Toll's stock price surged 14.3% to $23.40 Wednesday as investors saw the luxury home builder's preliminary results as a sign of improving confidence among potential home buyers, many of whom until recently have been scared away by expectations of further price declines. Toll's net orders - contracts signed minus cancellations - totaled 837, up 3% from a year earlier, the first increase since 2005. In dollar terms, those orders were down 5% at $447.7 million.

"Fence sitters are looking for reasons to jump in on the side of buying," said Chief Executive Officer Robert Toll. He added that "price is no longer the overwhelmingly dominant factor." A rebound in the stock market and "a better feeling" about the economy and job prospects have helped, he added. "The mood has changed."

Buyers aren't flocking to shop for homes. "Our traffic still stinks," Toll said. But those who show up have become more serious about buying rather than just asking for ever-deeper discounts, he said. Among markets that have shown improvement recently, he said, are the New York suburbs, Washington, D.C., Virginia, the west coast of Florida from Naples to Tampa, and northern California.

Toll is cautious about encouraging customers to select quality upgrades that sharply raise the price, Toll said, because of the risk that appraisers, who have become more conservative, may nix transactions at prices that appear high in relation to other recent sales.

The Horsham, Pa.-based company recently has offered weekend specials, such as discounted upgrades on countertops or cabinets and mortgage rates of below 4%. The company's Web site touts "amazing incentives" and "special limited-time offers." But Toll said improving demand, especially since mid-July, has allowed it to reduce incentives in "many markets," primarily in the Northeast and mid-Atlantic states.

In the overall housing market, sales at the low end have been much stronger recently than those at the upper end. That's partly because mortgage rates are higher for "jumbo" loans, those too large to be guaranteed by government-backed investors Fannie Mae (FNM) and Freddie Mac (FRE). In the highest-cost parts of the country, Fannie and Freddie can guarantee loans up to $729,750.

But Toll has kept its prices low enough so that 73% of buyers were able to use loans backed by Fannie, Freddie, the Federal Housing Administration or other government entities in the latest quarter, a spokeswoman said. About 17% paid cash for their homes, and only 10% needed jumbo loans.

The average price for net purchase contracts signed in the latest quarter was $535,000, down 7.6% from a year earlier. Those prices don't include the value of subsidized mortgages or some advertised options, such as an added room, so the true price drop probably is more than 7.6%.

Builders generally have been shrinking homes to lure today's more cautious buyers. The average size of new detached single-family homes sold in the U.S. declined to 2,545 square feet in 2008 from 2,587 a year earlier, according to the U.S. Census Bureau. The average had been gradually increasing for years.

But Toll said in a conference call that he doesn't see such a trend for the upscale homes his company sells. "I don't see people wanting smaller homes," he said. "I think the luxury market is here to stay."

Toll said its orders in the third quarter normally are lower than those in the second quarter, which coincides with the spring buying rush, but this year orders in the third quarter were up 44% from the prior quarter. A rise in the third quarter from the second quarter has occurred only three other times since fiscal 1986, Toll said.

Fewer buyers got cold feet. Toll's cancellation rate in the quarter was 8.5%, down from 19% a year earlier and the lowest since the fiscal second quarter of 2006.

"Buyers are more conservative and careful" than they were during the housing boom, said Doug Yearley, a regional president for Toll. But many "still want the big house with all the upgrades," he said.

Toll's revenue fell to $461.3 million from $796.7 million a year earlier. Earnings and other data for the quarter are due to be released Aug. 27. Toll estimated that pretax write-downs related to operating communities, land and land options and joint ventures in the third quarter will be between $90 million and $160 million.
