Another trend JLL's mid-year bulletin highlighted was the build of foreign investor interest in US assets. Collins says he believes international buyers will play a large role in US commercial real estate investment through the end of this year and the first half of next year.

"The international capital has been sitting on the sidelines, watching from afar and waiting, but now you're starting to see international investment bubble up in the States," Collins says."Foreign capital didn't get burned as much, so now they're flush with capital and have more borrowing power because they never really went overboard before. Now with the value of properties going down and they're sitting on a lot of capital, they look at real estate in the US and we're seeing their attitudes of why not buy now, because I might not see a good deal like this again."

Just as activity appears to be increasing within international buyers, so too does JLL see an uptick in the willingness of foreign banks to lend money. "You're seeing people looking at assets and you're seeing a flight to quality, where buildings that are more leased with low rollover are more attractive," Collins says. "In terms of recovery, I think we're going to see things be more stabilized toward the third or fourth quarter next year and it's going to be more clear then."

Collins highlights the rebound of some markets internationally, namely in Australia and London, as well as central business districts domestically. "In a lot of the CBD markets, you're seeing good value being had and realized," Collins says. "Investors are coming to take advantage of that, with cash being king."
