2010 housing predictions

CNBC real estate reporter Diana Olick makes four predictions for the coming year:

1. The residential housing market will dip again in mid-2010 before settling into a recovery in the back half of the year.
2. Foreclosure inventory will be a lot higher than some predict.
3. No more historic lows on the 30-year fixed.
4. Commercial real estate will continue to suffer the ills of low vacancy rates, low rents and high default rates.
