Investments backed by commercial real estate loans have avoided the problems socking the home loan market, the Associated Press reported.

The Mortgage Bankers Association’s 2007 statistics show that investors in commercial real estate loans — which finance purchases of properties like apartments, office buildings and malls — have escaped the kind of defaults that have soared among home loans over the past year. The group expressed hope that the statistics will ease worries about the industry, which has seen investment dry up in recent months due to the global credit crunch.

Steve Graves, managing director and chief operating officer of Principal Real Estate Investors in Des Moines and chairman of the trade group’s commercial board, said commercial real estate loans remain a sound investment despite worries about the economy.

“A lot of what you’re seeing today is really fear of what might happen rather than what is happening,” he said.

The delinquency rate on loans packaged into investments known as commercial mortgage-backed securities has dropped from 1.7 percent at the end of 2003 to 0.4 percent at the end of 2007, the report said. The trade group’s report noted that among major commercial real estate investors, only banks and thrifts saw delinquency rates increase last year, growing to 0.8 percent from 0.56 percent in late 2006.

Still, the commercial property market isn’t immune to turbulence. Sales of office buildings worth more than $5 million fell to $4.3 billion in February, down 76 percent from $20.1 billion in the same month a year earlier, according to research firm Real Capital Analytics. The market for commercial mortgage securities “remains frozen,” and federal regulators are more closely scrutinizing all kinds of real estate loans, Real Capital said.

Construction and development loans are loans made to builders for properties such as strip malls, office buildings and residential developments. The percentage of those loans that are 90 or more days overdue rose to nearly 3.2 percent at the end of 2007, up from less than 1 percent a year earlier, and is now at levels not seen since the early 1990s, according to the Federal Deposit Insurance Corp.
