A couple hours ago Reuters reported that a panel appointed by President Obama recommended the end of tax breaks for things like Mortgage Interest Deduction. I don't know about your clients, but the this is one of the major reasons many of my clients want to own homes.
On one hand the government tries to spur home sales for a short period of time by offering the $8,000 tax credit - then they discuss finding ways to make homeownership less and less attractive. Not only is it irresponsible, it happened and was a huge failure in the 80s. Sure it would bring another windfall into the treasury - until people stopped buying houses.
I suggest calling your congressman and make sure they know the consequences to this action. I know I'm going to write mine:
