95% on time is a good metric to keep in mind . I keep coming back to the thought that we can possibly help put the bottom in place by rewarding consumers to start spending again.

Housing sales are a huge lever and there are apparently a fair number (not sure what it is) of people (first time homebuyers included) that are on the sidelines ready to go but want to wait for the market bottom.

Creating this expanded tax credit for new house purchases and possibly existing home sales is a good idea - I especially like making the credit expire at the end of 09 - it creates incentives to purchase and a sense of urgency to get going. From an economics perspective, this seems to be a way to generate demand.
