From The Wall Street Journal, April 25, 2007:

Tighter credit and a growing glut of properties are depressing an already weak U.S. housing market, wrecking the industry’s hopes for an early rebound.

That leaves buyers in a strong position to negotiate for bargains during the spring home-shopping season, the busiest time of the year for housing sales.

Lenders, stung by a surge in defaults, have rediscovered the virtues of caution over the past few months, eliminating many of their no-money-down loan offerings. That tightening is “really starting to bite,” says Ed Mixon, a real-estate agent for Re/Max Real Estate Services in Monarch Beach, Calif.

Mr. Mixon recently had to advise one of his clients, a young woman with a good job and credit record, to put off her dream of buying a $300,000 condo in Laguna Niguel, Calif., until she could come up with more than her current nest egg of $5,000 for a down payment. A year ago, he says, she could easily have obtained a loan to cover 100% of the condo’s price.

Stricter lending standards will reduce demand for housing by 10% this year from where it would have been had credit remained loose, estimates Thomas Lawler, a housing economist in Vienna, Va. He expects housing prices, as measured by the national S&P/Case-Shiller index, to fall 7% in the fourth quarter of 2007 from the year-earlier level.
