The Obama administration blessed the proposed extension of the $8,000 tax credit for first-time home buyers on Thursday as the Senate neared a compromise that would extend the credit to more potential buyers.

Here’s a primer on who might be able to get the expanded credit, and what it might do for the housing market:

Who gets the credit, and how much can they claim? First-time home buyers are eligible for up to $8,000 on the tax credit, which is the same as the current credit. The Senate version of the bill creates a new credit of up to $6,500 for homeowners who have lived in their homes for five years. That provision would start on Dec. 1.
