Current conforming loan limits are scheduled to expire Friday, Sept. 30. The maximum FHA, Fannie Mae, and Freddie Mac conforming loan limit will decline to $625,500 beginning Oct. 1, 2011, from the current $729,750 limit, though the majority of counties will fall far below the $625,500 maximum. The conforming loan limit determines the maximum size of a mortgage that FHA, Fannie Mae, and Freddie Mac government-sponsored enterprises (GSEs) can buy or guarantee. Non-conforming or jumbo loans typically carry a higher mortgage interest rate than a conforming loan and require a higher down payment, increasing the monthly payment and negatively impacting housing affordability for California home buyers.
