Why should I buy now? If I waited, prices could be lower later in 2009.

Points to address this buyers question: 

The are a few things to consider when considering this question. 

Mortgage rates are the lowest in decades. A mortgage at today's rates could save you thousands in the long term. No one really knows when they may go up again. 

You can't really time the market. We don't know for sure that home prices may go a lot lower. There is lots of inventory to choose from at the moment.

We DO know that real estate has always been a great investment in the long term. Prices WILL go up. 

Sellers on the market today are motivated. Now is a good time to negotiate a good price on your new home.

The government economic policy of printing money will lead to inflation in the future and prices will rise.
