Buying a home is a big-time real estate investment and has to be done with great prudence. Knowing where not to buy a home is as important as are the dos and don'ts of buying a home.

Of the many top ten lists on CNNMoney.com, there is listed the top ten overvalued cities in America where it is better not to buy a home for the next two years or so. The report states a variety of reasons for the unfavorable market conditions.

Five cities in California - Bakersfield, Fresno, Merced, Sacramento and Stockton, figure among the top ten cities that have the least possibility of home price appreciation. Home prices have reached a new high (by nearly 60%) in these areas over the past two years. With an economy driven by agriculture and relatively higher unemployment rates anticipated for that area, the real estate market is predicted to slump in the region.

Although three cities in Florida are recommended as good real estate buys, the report also cites four others in Southwest Florida that fall among the very bottom of the list. With home prices here expected to plummet very soon, cities like Fort Myers, Naples, Punta Gorda and Sarasota are those that one would do best to avoid for a year's time or so, while buying a home or a condo.

Market prices are expected to decline in the Jersey Shore (New Jersey) area that saw a radical boom in the last two quarters. Although home prices in the third quarter have rebounded from the slight drop during the second quarter, the bubble is expected to burst soon and the overpriced market is likely to stabilize. The popular seaside cities of New Jersey, Atlantic City and Ocean city are anticipated to fall under the unfavorable list.

In Phoenix, Arizona, a hot favorite among investors last year, sliding home prices may to be an unavoidable occurrence in the next 12 months. With home prices dropping by more than $100,000 in some residential developments and investors trying to sell off their property, it is safer to wait for a year or longer before investing here.

Economists at Moody's Economy.com also predict a sharp decline in Riverside and San Bernardino counties, California's Inland Empire.

The bottom ten cities that are likely to see major drops in median home prices during the coming year are Stockton, (leading the list with a predicted fall of 9.7%), Merced, Reno/Sparks, Fresno, Vallejo/Fairfield, Las Vegas, Bakersfield, Sacramento, Washington, D.C and Tucson.

Given these fluctuating real estate market conditions, one should exercise a great deal of caution when investing in real estate. It makes sense to get the expert advice of a real estate agent to advise you about your next home purchase, since agents often have access to the most up-to-date real estate market data and neighborhood pricing trends.
