Demographics and consolidation drive demand for medical office buildings

National construction of medical office buildings (MOBs) stood at 12.5 million sf in the first quarter of 2017, down slightly from a few years ago but still well above recession-era levels. However, construction continues to be outpaced by net absorptions, which between 2015 and Q1 2017 totaled 35.4 million sf, or 38% higher than completions over that same period.

In its first-ever report on U.S. Medical Office Buildings, CBRE notes that the vacancy rate for MOBs has “tightened steadily” since 2010, to its current level of 8%, a record low for this sector and well below the 13% vacancy rate for the U.S. office market.

To assess what’s driving MOB demand and development, CBRE took looked at Class A and B buildings with at least 10,000 sf of rentable area specifically designated as medical office space in 30 metros, with detailed investment and demographic profiles of each city.

It found a “resilient” MOB market that continues to benefit from several factors, not the least of which being the population growth of senior citizens. The U.S. Census Bureau estimates that the 65-plus population will nearly double between 2015 and 2055 to more than 92 million, and comprise nearly 23% of the country’s total population.

“The steep increase in both the 65+ population and anticipated greater need for in-office physician services by this group signal a continued increase in demand for health care services and medical office space in the decades ahead,” CBRE states.

Markets where the 65+ population is expected to grow strongest over the next five years include Las Vegas, Phoenix, Atlanta, Dallas-Fort Worth, Houston, and South Florida, according to Moody’s Analytics.

CBRE observes that providers are attempting to stem perennially increasing healthcare expenditures by moving more patient volume away from hospitals and toward more cost-effective outpatient facilities, such as MOBs and urgent-care centers.

Another cost-cutting trend that’s impacting healthcare real estate, says CBRE, has been the “significant uptick” in mergers and acquisitions. Consolidation among physician medical groups has been particularly strong, with deal volume surging by 19% in 2016 and 109% year-over-year in Q1 2017, according to PwC.

Overall asking rents for medical office properties have remained relatively stable over the past seven years, ranging between $22 and $23 per sf per year. CBRE explains that the high cost of tenant build-outs, as well as the importance of proximity to a provider’s patient base and ancillary medical services, compel many tenants to remain in place for long periods of time.

But rent appreciation varies widely by market; average rents in New York, for example, grew by 83% since Q1 2010 to over $68 per sf in Q1 2017. Indeed, almost all of the 30 markets examined registered rent increases over the past year. And investors surveyed expect MOB rents to increase between 1% and 3% this year.

Low vacancy rates in this sector are attributed, in part, to the widening gap between completions and absorptions over the past three years.

On a yearly basis, net absorption has been increasing since 2011 when it totaled 8.1 million sf. Since then, annual absorption grew by 114% to 17.2 million sf in 2016. Four of the five markets with the most positive net absorption in 2016 were located in the South or West: Houston (436,300 sf) Tampa (413,800 sf) Phoenix (314,400 sf) and South Florida (310,703 sf). Indianapolis was the lone top market not located in the Sun Belt, ranking third with 383,700 sf of positive absorption.

CBRE found that as investors’ appetites for healthcare-related properties have increased, MOBs “have emerged as the most popular property type within the niche.” Ninety-seven percent of investors surveyed in 2017 were most interested in medical office properties among all health care-related real estate that met their investment criteria.

CBRE cites Real Capital Analytics research that estimates total U.S. investment volume in MOBs of at least 10,000 sf at $10.2 billion in 2016, compared to just under $4 billion in 2010. The investment total in 2016 exceeded the previous annual peak of $7.3 billion in 2006.
