TAMPA, FL—Capitalization rates are compressing in Tampa. But what's causing it? How have interest rates affected the trend? And where do we go from here? GlobeSt.com caught up with Jonathan Graber, a retail investment associate with Franklin Street's Tampa office, to get his take on these questions.

GlobeSt.com: What is happening to the cap rates in Tampa?

Graber: Capitalization rates are at all-time lows. We have seen them compress anywhere from 25 to 50 basis points on single tenant net lease assets since the beginning of 2014 with some tenants seeing a larger compression. While it is much harder to define cap rates on anchored and unanchored shopping centers, because there are so many variables that come into play, they are still significantly lower than they were in 2012 with some eclipsing levels we saw during the bubble years.
