More than 15 states are projected to experience housing inflation or appreciation during the year, according to Housing Predictor, which releases an annual report of its choices for best and worst housing markets.

The top five housing markets are:

1. Portland, Maine
2. Kansas City, Kan.
3. Tri-Cities, Wash.
4. Omaha, Neb.
5. Fargo, N.D.

However, not all markets will fare well in 2011, with the foreclosure crisis particularly still battering some areas as well as high unemployment and overbuilding during the boom era that has led to high home inventories.

The top 5 worst markets, according to Housing Predictor, are:

1. Bend, Ore.
2. Las Vegas
3. Atlantic City, N.J.
4. Miami, Fla.
5. Medford, Ore.
