What are the specifics?  Well you'll be able to use the $8000 on contracts through April with some expanded income qualifications.  And you'll be able to qualify for up to $6500 even if you're NOT a first-time buyer.  You will have to have owned your current home for 5 years.  This leaves some people out who could really use the $6500, but hopefully it will lead to better inventory for all the first-time buyers.
