The trends in online shopping continue to pressure the retail class, although there is nuance. As consumers shift away from shopping at mall anchors, the Class B and Class C malls are challenged to attract retailers and shoppers alike. However, some retailers are using innovative tactics that blend online, mobile and brick-and-mortar strategies, which are fueling positive trends for A-class retail properties.

3. Millennials Still Lead the Push Toward Urban Living

The millennial generation and those behind it continue to show a strong preference for living in vibrant metro areas. In most markets, millennial renters typically value proximity to work and social activities over building space or amenities. The greatest increase in value in the multifamily asset class is found in major cities and owes to these millennial renters.

In the highest-paying job markets, one challenge is that there isn't enough affordable housing to accommodate demand. Additionally, there's limited need for the high-end multifamily buildings that are being built today—instead, younger renters in every market are moving into potentially less developed urban areas to find more affordable housing.

Notably, while the millennial cohort's renting preferences are largely consistent across the country, some older millennials in markets like Pittsburgh and Cincinnati are following the more traditional renter-to-buyer cycle and are purchasing homes in suburban areas.

4. New Construction Provides Challenges and Opportunities

Incentives in the 2017 Tax Cuts and Jobs Act may help address the growing demand for affordable housing. The Opportunity Zones program provides tax incentives for investing in low-income communities. For investors, the program is an opportunity to save on capital gains while also developing units in areas where it might otherwise be difficult to build. And it's not just housing. New retail properties, such as grocery stores, simultaneously cater to the local community while also catalyzing further investment and economic activity.

While these and other CRE investments offer big opportunities, one dominant challenge is the shortage of skilled labor. As baby boomers exit the workforce, younger generations eschew skilled trades and immigration policies restrict new workers from entering the country, there's an intense need for labor—not only for new construction but also for things like renovation and maintenance.

5. The Down Cycle Isn't Here Yet, but It's Coming

The economic data and trends in the CRE industry overall don't suggest a looming correction, despite some concerns in late 2018. That said, the current cycle will at some point end and rates will eventually increase. Knowing that, investors can plan for it. CRE investors should stress-test frequently to ensure they can withstand cash flow pressure should a correction occur. They should also ensure they aren't over-leveraged in order to be able to weather a modest downturn and prepare for the next cycle.

We're constantly planning and preparing for an unforeseen downturn—even a potentially severe one—so that we're always in a strong position to help our clients take advantage of the cycle. Even as CRE investors seize opportunities growing out of low rates and a strong economy, they should also continue preparing for future opportunities by managing their debt and expenses and building the liquidity they need for the long term.
