The World's Most Valuable Real Estate Markets: Knight Frank, Citi (PHOTOS)

After a historic real estate crash, we're all understandably wary about investing in property. For those in the position to spend serious amounts of money on property, however, the world's great cities seem to have lost little of their luster.

With the markedly affluent buyer in mind, Knight Frank and Citi Private Bank have put together an in-depth look at the world's most attractive real estate markets. Their annual Global Wealth Report ranks the world's leading cities on several factors, including economic activity, political power (always a plus for the rich buyer), knowledge and influence (who wouldn't want more of that?) and quality of life.

The result is a composite look at the cities that will be attracting the biggest share of high-net worth individuals -- 71 percent of whom, according to the Global Wealth Report's survey, say 2010 will be a good year to invest in real estate.

With that mild bit of reassurance in mind, check out the world's most valuable real estate markets below:
