“It was kind of crazy we could get this big a loan,” said Mr. Rowland, 27. “If a government official came out here, I would slap him a high-five.”
In its efforts to prop up a shattered housing market, the government is greatly extending its traditional support of real estate, including guaranteeing the mortgages of middle-class and even upper-class buyers against default.
In 2007, the government did not insure a single mortgage in this city, one of the most expensive in the country. Buyers here, as well as in Manhattan, Santa Monica and every other wealthy area, were presumed to be able to handle the steep prices and correspondingly hefty down payments on their own.
Now the government is guaranteeing an average of six mortgages a week here. Real estate agents say the insurance is such a good deal that there will soon be many more.
Policy changes like the shift in insurance, while often introduced on a temporary basis, are becoming so popular that they could prove difficult to undo. With government finances already under great strain, the policy expansions are creating new risks for American taxpayers.
The Internal Revenue Service is giving tax rebates to first-time buyers, and soon to move-up buyers, in a program beset by accusations of fraud. And the government agency that issues mortgage insurance, the Federal Housing Administration, is underwriting loans at quadruple the rate of three years ago even as its reserves to cover defaults are dwindling. On Thursday, the Mortgage Bankers Association said more than one in six F.H.A. borrowers was behind on payments.
F.H.A. insurance was created for minority and low-income families who could not come up with the traditional down payment of 20 percent required by private lenders. Buyers receive loans from government-approved lenders and are required to document their income and assets. They must pay a substantial insurance premium of 1.75 percent of the loan. But in return, their down payment can be as low as 3.5 percent.
For decades, most F.H.A. loans were in low-cost states like Texas and Michigan. Under the agency’s loan limits, houses along the coasts were usually too expensive to qualify. In 2007, fewer than 4,400 F.H.A. loans were made in California, according to the research firm MDA DataQuick, and none were in San Francisco.
The Economic Stimulus Act of 2008 helped change that by temporarily doubling the maximum loan the F.H.A. insured, to $729,750. A two-unit property like the one bought by Mr. Rowland and his friends can be insured for up to $934,200.
“F.H.A. financing was a lost language in San Francisco, the real estate equivalent of Aramaic,” said Michael Ackerman, the agent who represented Mr. Rowland and his friends. “Once the limits were raised, smart buyers started calling.”
The F.H.A. has insured more than 107,000 loans so far this year in the state, according to DataQuick, about 270 of them in San Francisco.
Condominium buildings approved for F.H.A. financing — a relative handful — trumpet the news on their Web sites. The Soma Grand, a new 246-unit building downtown where one-bedrooms cost in excess of $500,000, received F.H.A. certification early in the summer. A half-dozen buyers since then used F.H.A. insurance.
At Guarantee Mortgage Corporation, which has 150 mortgage brokers in the Bay Area, Seattle and Portland, Ore., F.H.A. loans have grown to about 15 percent of its business, from less than 3 percent a few years ago.
“It sure has helped us put a lot of deals together,” said Guarantee’s chief sales officer, Bob Siefert. He predicts that a quarter of Guarantee’s deals will soon be guaranteed by the F.H.A.
Some F.H.A. borrowers here say they have the cash for a full down payment but would rather invest it in the stock market or use it for remodeling. Others, like Mr. Rowland and his friends, simply do not have the money required by private lenders — which would have been nearly $200,000, in their case.
