Jim Glassman, managing director and senior policy strategist with J.P. Morgan Chase & Co.,  said that prospective home owners will have to return to how their parents bought homes and start saving more money for a downpayment.

"The customer you have known for the past 20 years is not the customer you will know in the next 10 years," he said, as the economy transitions into a new era that "won't feel like it has as much oomph."

The best news for the economy, he said, is that the emerging economies, largely in Asia, are doing fine and providing strong demand for U.S. exports and providing U.S. companies with "spectacular levels of profits."

"The world has never seen such great economic performance since the dinosaurs," Glassman said, and as a result, the winds are shifting in favor of regions of the U.S. that rely heavily on exports, including Michigan.

In NAHB's latest housing forecast, new single-family home sales are projected to decline 21.8% this year, to 605,000, before climbing 18% in 2009 to 714,000.

Total housing starts are forecast to decline 29.5% to 948,000 in 2008 and rise 10.8% to 1.05 million next year. Most of this year's decline will be concentrated in single-family production, which is expected to drop by 37.1% to 653,000 homes.

Home prices are down about 12% since the height of the housing boom in 2005 and incomes have grown 14%, bringing "prices relative to income to about where they were in 2003" during this year's first quarter, he said. "We have flushed out most of the excess."

Glassman said his guess is that home prices will decline 5% or so further, but gloomier forecasts foresee another 15% to 20% drop, and what will actually happen is probably somewhere in between those two views. "By fall, we will start to see that most of this is over," he predicted, but he conceded that he wished he knew "where home prices would settle out."

The outlook for housing and the economy should be gradually brightening within a few months, but before there can be any assurance that the worst of the downturn is over, there needs to be a pickup in home sales, according to panelists at NAHB's Spring Construction Forecast Conference on April 24 in Washington, D.C.

Residential production and sales this year have declined "more sharply than anticipated," said NAHB Chief Economist David Seiders, and the situation for the U.S. economy "definitely has darkened," with more than an even chance that it has lapsed into a "mild" and brief recession in the first and second quarters.

Seiders said that he continues to believe that new single-family home sales will stabilize during the middle of this year, paving the way for an upturn in late 2008 and in 2009 and leading to improvements in housing starts next year. However, "the sales side has to be off the deck before starts stabilize and move up," he said.

And so far, he reported, there are few signs that new single-family sales are close to bottoming out, with the Commerce Department just announcing an 8.5% decline in March, to a seasonally adjusted annual rate of 575,000, a 17-year low, and increasing the unsold inventory to an 11-month supply at the March sales pace.

Through March, Seiders said, NAHB surveys of 30 large builders accounting for 25% of sales nationwide, showed "no signs of stabilization, although the rate of the decline may be slowing." Likewise, the NAHB/Wells Fargo Housing Market Index, which polls builders to gauge their opinion of current sales conditions and demand six months down the road, remains close to its record low recorded in December and "shows no recovery yet, implying further deterioration of sales."

"We need demand to revive to turn around the market," Seiders said, and he suggested that a temporary tax credit for home buyers, an approach being considered in housing and economic stimulus legislation on Capitol Hill, could help provide the impetus to boost sales and end the downward spiral in home prices that is the biggest concern for the health of the nation's economy.

As home prices have declined, he said, "underwater" mortgages with balances exceeding the value of the home have been adding to the deterioration of loan quality that began in the subprime sector last summer. This is "bad for the financial markets," he said, and could result in further tightening of lending standards, yet more foreclosures and even softer housing demand.

Economists participating in the conference were fairly optimistic that the downward turn in housing prices, while substantial, will taper off before it takes a toll on the longer-range outlook for the economy, but nobody can know for sure, they said.

Seiders also stressed that there are negative implications for the economy if housing does not move into positive territory next year. The tax rebate checks that households will soon begin receiving as part of February's economic stimulus legislation should help revive the economy during the second half of this year, he said, but growth in housing will be needed to keep the economy on a positive course in 2009 as that stimulus fades.
