Expanded homebuyer credit: Who wins?

Legislation that would extend and expand the homebuyer tax credit is awaiting the signature of President Obama.

The credit would run through next spring, though consumers would need to commit on a home purchase by late April.

In addition to extending the $8,000 credit for first-time homebuyers, a $6,500 credit will be offered to existing homeowners who sell their current property and purchase a primary residence that costs $800,000 or less.

What does the legislation mean for homebuyers? And for sellers? A number of Web sites are examining the details, including Bank Rate Monitor.
