Thousands of first-time homebuyers will be able to get short-term loans so they can quickly make use of a new $8,000 tax credit that was designed to boost the battered U.S. housing market.

The Federal Housing Administration on Friday released details of a plan in which borrowers who use FHA loans can get advances from lenders that effectively let them receive the credit before they complete their taxes.

The FHA had no estimate of how many borrowers would qualify. But the agency, which backs about a quarter of new home loans, is projected to guarantee about 2.2 million loans in the next budget year.

Borrowers can claim the credit by filing an amended 2008 tax return or can wait for their 2009 return.
