http://www.nytimes.com/2011/03/20/realestate/20Mortgages.html?_r=1&hp IN the years since the financial crisis, adjustable-rate mortgages, or ARMs, with their low initial interest rates that changed over time, have been considered riskier than fixed-rate loans and shunned by most buyers. But these days more people are being persuaded to give the loans a try.

Those ARMs were hallmarks of the subprime mortgage boom that fueled the soaring rate of mortgage defaults and home foreclosures nationwide. âAn adjustable now is basically a prime product,â said Michael Moskowitz, the president of Equity Now, a lender in New York. âThereâs definitely a comeback in their popularity.â Bank of America, for example, had nearly twice as many ARM transactions last month as it did a year ago, according to Terry H. Francisco, a spokesman, and ARMs now account for 10 percent of all its home loans. Mortgage brokers and lenders say the loans most in demand are the â5/1â and â7/1,â in which the initial interest rate is fixed for the first five or seven years â after which many homeowners typically think about selling or refinancing anyway â then adjusted annually at a capped rate toward a maximum level. In contrast to fixed-rate loans, whose interest rates never change, ARMs start out at one rate and then adjust typically once a year at a capped rate, often two percentage points, based on changes in the interest-rate indexes to which they are tied. The adjusted rates can go up or down, and the total increase over the life of the loan is capped. According to Stephen Habetz, the vice president of DRB Mortgage, the lending division of Darien Rowayton Bank in Darien, Conn., the maximum caps are around 6 percent above the initial rate. Bankrate.com said the initial rate for a 5/1 ARM in the New York area averaged 4.04 percent as of Wednesday, compared with 3.74 percent nationally. For 7/1 ARMs, the average was 4.74 percent, versus 4.10 percent. Starting rates are usually one to one and a half percentage points below those of 30-year fixed-rate loans. But one catch is that getting an ARM may now be harder. Last summer Fannie Mae, the government buyer of home loans, said lenders must qualify borrowers on either the initial rate plus two percentage points, or on the full index rate to which the initial rate is tied, whichever is greater. Back in 1994, ARMs were used for around 70 percent of all home purchases, according to a study by the Federal Reserve Bank of New York released in December. By early 2009, after the onset of the financial crisis, the share had fallen to 2.3 percent, the study showed, but as of April 2010, it had climbed to about 4 percent. Freddie Mac, another government-buyer of loans, said in January that it expected the share of ARMs for home purchases to rise to 9 percent this year. Among those borrowers choosing adjustable-rate mortgages are buyers of property costing more than the $729,750 limit at which Fannie Mae and Freddie Mac will buy back loans from lenders, said Mary Boudreau, the owner of Penfield Financial, a mortgage broker in Fairfield, Conn. (Without the government buyback, fewer lenders are willing to make these âjumboâ loans, which carry interest rates one or two points above those of conventional loans. The Fannie and Freddie limit is set to drop to $625,500 in October.) With an ARM, the savings can be significant. Sean Bowler, a loan officer at DRB Mortgage, said someone borrowing $500,000 with a 5/1 ARM at 3.5 percent would save $42,507 in the first five years, before it adjusts, compared with a 30-year fixed-rate loan of 5.25 percent. A 7/1 ARM at 4.125 would save $38,330 over the first seven years.
