Property Values Continue Sideways

Newport Beach, CA, May 4, 2018 — The Green Street Commercial Property Price Index increased by less than one-half of a percent in April. The index, which measures values across five major property sectors, has been trending sideways for the past two years.

“In aggregate, commercial property pricing has changed little over the past year, but values for some property types have been moving higher and others are falling” said Peter Rothemund, Senior Analyst at Green Street Advisors. “Industrial, life science, medical office, and manufactured home communities are all up 10% plus over the past year while retail is down that much.”

How is our index different than others that track commercial property prices?


Green Street’s Commercial Property Price Index is a time series of unleveraged U.S. commercial property values that captures the prices at which commercial real estate transactions are currently being negotiated and contracted. Features that differentiate this index are its timeliness, its emphasis on high-quality properties, and its ability to capture changes in the aggregate value of the commercial property sector.

What makes our commercial property price index unique?

There are significant differences between the Green Street CPPI and other indices that track commercial property prices. Green Street’s CPPI is appraisal-based. Appraisal-based indices are only as good as the valuation estimates used to construct them, and Green Street has long devoted sizable resources to deriving accurate estimates of the values of the properties owned by REITs. Most other indices are transaction-based.

Institutional Quality

Institutional Quality

The index is based on Green Street’s frequently updated estimates of private-market value for REIT portfolios across the five major property sectors (apartment, industrial, mall, office and strip retail – aggregate asset-value of $600 BN). Since REITs own high-quality properties, the index measures the value of institutional-quality commercial real estate.



Our index reflects changes in commercial property values as soon as we hear about them. That’s one of the benefits of an appraisal-based index; we don’t have to wait for deals to close. Most other indices are based on closed transactions, so they convey information several months old.



We place more weight on high-quality properties, e.g. a New York skyscraper has a much greater impact than a suburban strip mall. Because our CPPI is value-weighted, it measures what’s happening to real estate prices in aggregate, similar to the Wilshire 5000 that measures what’s happening to the stock market in aggregate. Most property indices are equally-weighted.
