Commercial real estate values and investment will rebound soon, as assets in most core U.S. markets, including Boston, are now trading well below their fair value, DTZ’s chief researcher said today.

"Between 2010 and 2014, we expect a bounce-back in values and rents that will catapult the U.S. and the UK to the top of the return chart," said Hans Vrensen, head of global research of London-based real estate adviser DTZ.

"2008 seemed like the beginning of the end, both for real estate and for the financial markets," said Vrensen, who unveiled DTZ’s annual Money into Property report in Boston this morning. "Now there are an unprecedented number of opportunities in commercial real estate."

Vrensen rated 80 percent of U.S. commercial markets, including Boston, New York, Chicago and Los Angeles, as hot buys. A year ago, no city in the country earned that recommendation.

DTZ’s annual lender survey found that, globally, lenders are expressing much more optimism about real estate investment than they were a year ago. Two-thirds of lenders DTZ surveyed said they were considering increasing their lending volume this year, while 68 percent say they will likely do more lending in 2011.

Significantly, the number of lenders saying they’ll likely lend less has evaporated. Last year, 47 percent of those surveyed said they would be decreasing their lending volume; none said they’d decrease lending in 2010 and 2011.

"There’s improving investor and lender confidence in the market," said DTZ researcher David Green-Morgan. "Globally, lenders are showing a marked optimism. Capital, and rental growth, will return."
