Stock investors never find it shocking that the market constantly rises and falls, but real estate has always been considered a more reliable and tangible form of investing. Volatile real estate markets, however, are becoming the norm. While there are still cities where property has the potential to accrue in value at a gradual pace, there are also many where it can go from hot to cold in a short span of time. The following list is of five markets in the United States that may be too risky for the real estate investor adverse to such volatility.

Los Angeles

Those who shell out the big bucks necessary to currently purchase a place in Long Beach, may very well find themselves unable to rent it out at a price that justifies the investment. Why is that? You can’t rent for more than the average renter in a particular area makes, and rents in L.A. are moving well beyond the median income and job growth stats in many of its counties.

Miami

Wages are not rising in Miami as fast as home prices are. The strength of the dollar has recently become a deterrent to foreign investors from countries such as Russia and Canada from investing. Future luxury condo construction has been slowing and existing inventory is being advertised at bargain prices.

Portland

The small home with a manageable mortgage that a young couple seeks out has become close to impossible to afford here in this city with the second largest population in the Pacific Northwest. Again, the price of the average home here exceeds that of the salary of the average worker, one reason for accelerating prices being a shortage of inventory.

Denver

Homes in Colorado’s capital city are pricier than ever. They’re even being sold for more than what sellers were asking in this city at the foot of the Rocky Mountain range right before the Great Recession kicked in.

Orlando

There has been an increase of 8.5 percent in the sales prices of homes in this town that is home to the Walt Disney World Resort, one of the most popular tourist attractions in the world. Orlando stands out, however, in that many, including area real estate agents, believe the robust local job economy can sustain the quickly-rising cost of purchasing homes here.

There are some who claim to have seen the housing bubble of 2007 coming. Those same fortune tellers can’t resist forecasting another bubble heading towards America’s most heated real estate markets. Real estate investors shouldn’t let fear stop them from buying in some of the country’s hottest markets, however. They should just remember that the safest way to proceed when looking for a city to buy real estate, is to make sure that the salaries and jobs of those who live there support the hype.
