NAR has sought removal of the repayment requirement because it discourages buyers from taking advantage of the tax credit. The three-year minimum holding period is a safeguard against speculators' use of the credit. The legislation also extends the effective date of the credit to December 1 from June 30, and extends eligibility to borrowers who buy their home with the help of state or local financial assistance that comes from the proceeds of tax-exempt mortgage revenue bonds.

The start date for the first time homebuyer credit is January 1, 2009 through and before December 1, 2009.

FHA and conforming loan limits. Specifics have not been released but reports indicate that the 2008 limits have been reinstated for 2009 except in those communities where the 2009 limits are higher. Additional increases in individual communities may also be available at the discretion of the secretary of the U.S. Department of Housing and Urban Development.

Foreclosure mitigation and neighborhood stabilization. Funding for states and localities to be used for neighborhood stabilization activities for the redevelopment of abandoned and foreclosed homes are authorized. Some news reports put the funding level at $2 billion.

Low-income housing grants. Allow states to trade in a portion of their 2009 low-income housing tax credits for Treasury grants to finance the construction or acquisition and rehabilitation of low-income housing, including those with or without tax credit allocations.

Tax-exempt housing bonds. Tax-exempt interest earned on specified state and local bonds issued during 2009 and 2010 will not be subject to the Alternative Minimum Tax (AMT). In addition, financial institutions will have greater capacity to purchase tax-exempt state and local bonds.

Energy efficient housing. Grants for energy retrofits for federally assisted housing (Section 8), funding for energy efficiency and conservation block grants to states, increases in the residential tax credit through 2010 for certain energy efficient upgrades and $5 billion to weatherize low-income homes.
