Risk Management and Homeowner Stability Act of 2017 This bill amends the Congressional Budget Act of 1974 to prohibit the chairs of the congressional budget committees from counting increases to guarantee fees as offsets for budget enforcement purposes. The bill includes an exception for legislation that increases guarantee fees to finance reforms to the secondary mortgage market. (Guarantee fees are charged by enterprises, such as the Federal National Mortgage Association [Fannie Mae] and the Federal Home Loan Mortgage Corporation [Freddie Mac], to guarantee the payment of principal and interest on loans. This bill prevents the fees from being used to offset provisions that increase the deficit in determining whether a budget point of order applies to legislation.)
