"A lot of little ones can add up, but nothing that's really, 'Wow! That moves the needle,' " said JLL managing director Matthew Cheezem in Miami. " Even outside of HQ2, Amazon took an entire building, a few hundred thousand square feet in downtown Nashville, Tennessee. Hertz went to Florida's West Coast. These are thousand-plus employers making huge investments in those local economies and driving job growth in those local markets. We still haven't seen that, and that would move the needle for us. We've seen a ton of 50-employee-and-under companies come in but nothing in a scale that really makes a huge difference."

Miami-Dade and Broward counties last year drew plenty of 3,000-10,000-square-foot companies, which accounted for most of the office absorption, according to Colliers International data. Miami-Dade posted a positive 500,000-square-foot absorption last year, but Broward and Palm Beach counties closed the fourth quarter with negative absorption at 172,860 square feet in Broward and 182,514 in Palm Beach.

"We definitely have room to grow," said attorney Joseph Hernandez, who leads the real estate practice at Weiss Serota Helfman Cole & Bierman in Coral Gables.

It's not all bad news as over 70 financial firms moved to Palm Beach County in the last three years and the Broward financial service sector last year experienced the biggest employment growth at 3.7%, data shows. Broward still saw some big expansion, notably human resource software maker Ultimate Software Inc. growing beyond its Weston base into a three-story, 100,000-square-foot building at Sunrise's Sawgrass International Corporate Park.

One Colliers expert acknowledges Miami hasn't lured big corporate relocations but says it's not that type of town. Big back-office operations in Florida are more likely to go to lower-cost alternatives such as Tampa and Jacksonville. Miami is more of a place for front-office operations that come with highly skilled employees.

"I don't know that our market is a pure comparable to Atlanta or Charlotte where it's a corporate relocation" town, said Ken Krasnow, vice chairman of institutional investor services at Colliers in Miami. "But I do think we are going to start to see the big-name companies making much more significant presences in our market. Whether that's a financial services institution like a JPMorgan or whether that's a Google, you'll start to see significant divisions or operating subsidiaries of those kinds of companies making commitments to our market."

Affordability 

The affordable housing crisis, lack of tax incentives and the homogeneity of industries are some of the factors that could be stopping us from getting the likes of Amazon.

"If you look at our housing market, our apartment rents are higher, our cost of living is significantly higher" than other areas, Costandinides said. "People would need to pay higher salaries. We do not provide tax incentives for people to come here to bring their companies here. So when you look at it from a cost angle, if you have a large number of employees, we are probably losing out on that."

South Florida is accustomed to high-end condos and apartments that few can afford yet drive up the housing price for everyone. At the same time, income increases don't keep up with housing costs.

"There's plenty of demand by all sectors, but we tend to see developers developing things in areas that make products more attractive to usually more young urban professionals and more higher income markets," Hernandez said. "When you have a lot of that in your market, obviously they are going for higher rents. So when you look at the overall market statistics, yes it's going to skew up the rent number, and when you compare that to median income and the growth of the two, you can get results like what we have seen."

Then again, it could be factors other than affordability. Amazon decided to split its HQ2 between Arlington, Virginia and New York, despite high cost in both markets.

"I was in New York for a while. It's very expensive up there. And it would be extremely expensive for folks who work at Amazon to live up there," Hernandez said. "It turns out that the things that might have kept us from getting Amazon didn't necessarily keep New York from getting it."

Amazon ultimately pulled out of its New York plan following opposition from residents and local leaders.

Future 

Krasnow expects movement soon.

"It's next. We will start to see some real change in the next 12 to 24 months. We are right there. We are right on the cusp," Krasnow said.

Miami office space is relatively cheaper than some other big cities, which companies notice.

Take the 56-story 830 Brickell tower underway in Miami's Brickell Financial District, where asking rents reached $73 a square foot, according to JLL. The average is $200 a square foot in New York and San Francisco, Krasnow said.

It's "relatively a bargain. It's expensive in our market, but it's all perspective," he said. South Florida "will be cost-effective for some of these companies relatively speaking to what they are operating in these other markets. That's all new. It's a transformation of the market as we are speaking. When we really have all the pieces in place that could attract these types of companies, then we will start to see real movement."

Beyond getting the high-end office buildings, South Florida is urbanizing to offer the live-work-play lifestyle coveted by employees. The city also is growing its art and culture offerings.

South Florida long has been a tourism, trade, real estate and service-driven economy, but Hernandez said more industry diversity is needed to appeal to corporations. He doesn't see real competitive change for at least another 10 years.

"One of the things that has been said about Miami is that we are growing into a world city. We are not quite there yet and comparable to New York or LA or London, but we are headed in that direction," he said. "That's what's exciting about the future of our city and the way it's growing. If we do this right, we may get there."
