Daniel M. Shlufman, president of FCMC Mortgage in Clifton, N.J., says federal reforms intended to make jumbo loans more accessible are "so much of a failure that it’s really unbelievable."

In early February, Congress gave beleaguered mortgage borrowers a rare cause for celebration. As part of the economic stimulus package, it passed rules intended to make it easier and less expensive for people to take out hefty loans in the nation’s costliest housing markets.

Economists and legislators said that helping tens of thousands of borrowers take out billions of dollars in new loans could stanch the bleeding in the housing market, spur spending and reduce the pain of a likely recession.

Instead, the effort to make it easier to get jumbo mortgages — loans over $417,000 — has yielded frustration and disillusionment.

Since the rules took effect April 1, many prospective borrowers and their mortgage brokers say the new loans are either not available or the rates are far higher than they expected. Relief, they say, has been replaced by grief.

The program “is so much of a failure that it’s really unbelievable,” said Daniel M. Shlufman, president of FCMC Mortgage Corp., in Clifton, N.J. Shlufman likened Congress’ effort to “coming up with a vaccine to a terrible disease, and then not giving it to people, or making it too expensive.” Under the new rules, a sizable number of jumbo loans would be treated by the mortgage industry the same as smaller conventional loans. This change — raising the ceiling for loans backed by government-sponsored housing finance agencies to nearly $730,000 in the nation’s costliest locations — was intended to bring rates down for more borrowers and stimulate the lending that is needed to get the economy moving again. The goal of making most of these jumbo loans accessible was aimed not at helping subprime borrowers, those people with spotty credit histories. Rather, it was meant for borrowers with good credit and ample down payments, but who wanted to buy a house or refinance a home loan in the costliest housing markets, like New York, San Francisco, Anchorage, Alaska, Baltimore, Edwards, Colo., and Jackson, Wyo.

In such markets, a two-bedroom home can easily cost more than $1 million.

But the real concern over this program’s failure goes beyond people seeking million-dollar homes. The danger, economists say, is in how a wave of foreclosures and rising inventory of homes for sale will deepen and prolong the economic downturn started by the subprime mortgage crisis.

Last year, around 14 percent of new loans were jumbos, compared with 8 percent for subprime and 48 percent for traditional conforming loans, according to Inside Mortgage Finance, a newsletter that tracks mortgage activity.

Robert Edelstein, a professor at the Haas School of Business at the University of California, Berkeley, said that it was essential to a healthy economy that jumbo borrowers in these upper-tier markets are able to get financing. “There could be a contagion,” he said, as the subprime woes “move up the chain.”

“The housing market has to stabilize,” he said. “And in these markets large loans are needed because the values are big.”

Members of Congress and people in the mortgage-backed securities industry remain optimistic about the new rules. They say it is too soon to declare success or failure.
