WASHINGTON (Reuters) - The Obama administration is exploring different ways to provide greater support for rental housing, a top U.S. Treasury official said on Friday.

One approach would be to expand the government's capacity to support lending for the multifamily market, Treasury's under secretary Jeffrey Goldstein told a national housing conference in Washington.

Goldstein said the administration is considering a range of reforms such as risk-sharing with private lenders to reduce the risk to the government and taxpayer.
