At the same time, the rise of the millennial generation and its interest in technology and collaboration will have a major influence on the future of commercial real estate. “Millennials have given rise to a 'sharing economy' in the US, and this has changed and will continue to change how stores market to shoppers, how office space and lifestyle hotels are featured, how online purchases are shipped and how new apartment communities are designed and laid out,” said Marisha Clinton, director of research for JLL Capital Markets.

As for investors, overall sales volume has increased in 2013, jumping 30% in the first three quarters when compared to the same period last year. However, the presence of institutions has softened somewhat over the past two years as the amount of core product available for purchase in primary markets has decreased. Accordingly, with the price of those assets rising, many non-institutional US investors are buying core assets in secondary markets. A sizeable chunk of international investors continue to target Los Angeles and Manhattan, but they too are broadening their reach to buy properties in secondary markets such as Houston and Seattle, where the energy and technology sectors, respectively, are thriving.

Broadly speaking, property operating fundamentals are improving, largely because of the rise in STEM employment and limited new development. A summary of each individual sector follows:

Retail vacancy rates should continue to inch down over the next year, as construction remains limited. The lack of new supply also will extend the ongoing recovery in rents. Investor interest in the slowly recovering sector is perking up, as investment sales increased to $33.8 billion in the first three quarters of this year, a rise of 14% from the first three quarters of 2012.

With small and mid-sized companies continuing to lease space, the industrial sector will experience additional rent recovery in the months and year ahead, and the overall national vacancy rate will settle at 7.9% at year's end. The sector also stands to benefit from the growing e-commerce industry and the deepening logistical requirements in the East. Investment sales reached $26.2 billion in the first nine months of 2013, marking a 34% increase from the same period one year earlier.

In the office sector, secondary markets in particular are benefiting from the job growth in the technology and energy markets. Markets with diversified economies should see increased tenant demand, and tightening conditions in CBDs should raise rents, particularly for large tenants. During the third quarter, positive net absorption was achieved nationally for the 14th consecutive quarter; approximately 9.6 million square feet was absorbed. Investment sales in the sector are robust and jumped 32%, to $62.9 billion, in the first three quarters when compared to the first three quarters of 2012.

Overall, the hotel sector continues to boast strong operating fundamentals and growth in revenue per available room (revPAR), and the national occupancy rate in 2013 is set to come just one percentage point shy of the 2006 peak. Going forward, expect further improvement in resort and select-service hotels, the latter of which has garnered more interest from off-shore buyers. Hotel investment sales are soaring, adding up to $14.6 billion in the first nine months of 2013, a dramatic increase from the first three quarters of last year.

The multifamily sector has dramatically reduced its vacancies since the Great Recession, and both occupancy rates and rents have climbed well above their 10-year averages. The sector's performance has been driven in large part by growth in STEM employment, which should continue to remain strong. Apartment investment sales totaled $71.5 billion in the first three quarters of 2013, up 29% from the same period in 2012.

Looking ahead to 2014, investment sales should continue to demonstrate positive momentum. Despite near-term headwinds related to domestic spending concerns, overall investment sales volume should increase approximately 15 percent in 2014 from its 2013 total. Furthermore, as the search for yield continues and the recovery broadens, expect to see growing interest from investors in core and value-add assets in secondary markets.

Additionally, the overall lending environment should remain healthy next year. While interest rates may increase modestly, which would signal an improving economy, the overall cost of capital will remain low from a historical perspective, and investors will have access to competitive product from the various lending categories.
