Real estate investors are turning their gaze from traditional "gateway" cities to those that pack more growth potential, according to a new report.

"As the economy and real estate expansion prepare to stretch into another year, the market does not feel the need to get overly defensive and move into [cities] that are often perceived as safe havens," says the 2019 edition of "Emerging Trends in Real Estate" from the Urban Land Institute and PwC.

The annual report found that investors are more willing to take some risks, and aren't necessarily looking at properties in cities such as New York; San Francisco; and Washington, D.C., traditional gateway markets that are considered prime investment territory because of their status as entry points into the nation and, therefore, greater likelihood of attracting foreign investment.

In the report's list of the 79 U.S. cities viewed as providing the best real estate investment prospects, for example, Washington, D.C., is at 18, Manhattan at 32 and San Francisco at 41. Many smaller, faster-growing cities are higher up on the list. Salt Lake City, for instance, is at 13, and Fort Lauderdale, Fla., is at 17.

"My thought is these faster-growing markets may be the best places to find ... opportunities," an institutional portfolio manager was quoted as saying in the report.

The report also noted that its list of hot cities in real estate appears to be getting more volatile. Seattle, for example, was ranked first on the list in 2017, but this year sank all the way down to 16.

The impact Trump tax reform has on growth potential could also impact the list, the institute said.

"The favorable treatment of real estate by 2018's tax law may also significantly increase the activity among local investors," the report said. "The bottom line is that opportunities are available in all markets."

As things stand now, according to the institute, these are the 10 most desirable real estate investment markets in the U.S., in ascending order:

10. Tampa/St. Petersburg, Fla.

Florida is a hot area for property investment in general, according to the report, with two cities in the top 10 and four in the top 20. Tampa and St. Petersburg have benefited from strong annual net migration over the past five years and an employment growth rate well above the national average.
