The single largest type of federal housing assistance is the home mortgage interest deduction.
In 2007, U.S. homeowners received $85 billion through this deduction1. Unfortunately, the benefits of the mortgage interest deduction are enjoyed primarily by the wealthiest Americans. Over 80% of the value of this deduction goes to homeowners in the top income quintile, according to a recent Pew Charitable Trust study on economic mobility.
In addition to the home mortgage interest deduction, the federal government spends over $40 billion each year for other housing-related tax expenditures due to capital gains, property taxes, and investor benefits (preferential treatment of bonds and the low-income housing tax credits).
