Increasing Activity, Challenges Still Remain
The second quarter of 2020 began with an unprecedented pause in activity for the Tampa Bay Retail market. Nearly every retailer, except those deemed essential during the COVID-19 pandemic, temporarily closed their doors either voluntarily or through government orders. Investors were pencils down and lenders halted underwriting and decision making. Tenants interested in the market paused or delayed tours, and many properties were pulled off the market in a wait-and-see approach. However, as the quarter progressed, the retail market throughout greater Tampa Bay began to thaw and, although many government orders and restrictions remain, pockets of activity began to come back to the market.

Steady Activity Amidst a Global Pandemic
Although the true long-term impacts of COVID-19 (Coronavirus) across the broader economy remain unknown, the local industrial market in Tampa Bay remained poised for growth.

Leasing volume, which is a precursor to absorption also increased registering over 2.8 million square feet of recently signed leases, nearly 1 million square feet more than the previous quarter. Big box tenants were the primary activity generators, completing six lease transactions, accounting for over 1.8 million square feet in transactions. The second quarter displayed a gain in momentum and an overwhelming drive for e-commerce product.

Industrial: The New Virtual Retail Storefront
The first quarter of 2020 will forever be marked as one of the most dynamic quarters in history for the industrial market throughout the Greater Tampa Bay region. As the 2020 year began, activity throughout (sales, leasing, construction) remained active and, in most cases, more active than year-end 2019. The flex market, albeit active for some time, began garnering more attention as tenants looked to potentially reduce costs from Class B office space into more affordable and comparable flex space. Interest rates were at near all-time lows, providing cost-effective financing that helped to bolster and carry on the 10-year record growth of development and investment activity experienced throughout the market. Unemployment in the region, the lowest in recent history and well below the national average, was championed by many in the local market.
