or 5 years, and is then adjusted annually according to market conditions and indices. The FHA Hybrid provides for an initial fixed interest rate for a period of three or five years, and then adjusts annually after the initial fixed period. The 3/1 and 5/1 FHA Hybrid products allow up to a 1% annual interest rate adjustment after the initial fixed interest rate period, and a 5% interest rate cap over the life of the loan. The new payment after an adjustment will be calculated on the current principal balance at the time of the adjustment. This insures that the payment adjustment will be minimal even on a worst case rate change. Down payment grants Down payment assistance and community redevelopment programs offer affordable housing opportunities to first-time homebuyers, low- and moderate-income individuals, and families who wish to achieve homeownership. Grant types include seller funded programs, the Grant America Program and others, as well as programs that are funded by the federal government, such as the American Dream Down Payment Initiative. Many down payment grant programs are run by state and local governments, often using mortgage revenue bond funds. On May 27, 2006, the Internal Revenue Service issued Revenue Ruling 2006–27, in which it ruled that certain non-profit seller-funded down payment assistance programs (DPA programs) were not operating as "charitable organizations". The ruling was based largely on the circular nature of the cash flows, in which the seller paid the charity a "fee" after closing. Many believe that the "grant" is really being rolled into the price of the home. According to the Government Accountability Office, there are higher default and foreclosure rates for these mortgages. On October 31, 2007, the Department of Housing and Urban Development adopted new regulations to ban so-called "seller-funded" down payment programs. The new regulations state that all organizations providing down payment assistance reimbursed by the property seller "before, during, or after" that sale must cease providing grants on FHA loans by October 30, 2007, with the exception of the Nehemiah Corporation. Nehemiah is the beneficiary of a lawsuit settlement with Department of Housing and Urban Development in April 1998. The terms of that settlement will allow Nehemiah to operate until April 1, 2008. Ameridream was granted an extension to the new regulations until February 29, 2008. Several similarly operated government grant programs were introduced in response to the IRS Revenue Ruling in May 2006.
