On Tuesday, HomeBanc Corp. said it will not issue any more loans, and Impac Mortgage Holdings Inc. shut down a type of loan called "alt-A" for people with limited documentation or slight credit issues.

That followed bankruptcies for two of the country's biggest home lenders -- American Home Mortgage Investment Corp. and New Century Financial Corp. -- and tighter terms at most other lenders that are thus far surviving a shakeout in the industry.

"Every day I hear about a number of lenders that are reducing their products," said George Hanzimanolis, president of the National Association of Mortgage Brokers. "It is going to take a while before the dust settles."

Stocks of many surviving lenders are at multiyear lows, and it is common to find shares in the industry that have lost 90 percent of their value in the past six months, or even weeks.

The shocks to the industry are siphoning lenders and cash away from the market, which reduces competition and restricts people's access to home loans.

Hanzimanolis said lenders have raised the minimum credit score that qualifies for financing. Most lenders now require bigger down payments, he said, and they are eliminating exotic loans or making it more difficult to qualify.

The silver lining is that people with good credit who can document their income have the same access to home loans as they did a year ago.
