Green Street: CRE Index Up 5% as Apartments Lag, Offices -34%

Finance professionals reading July 2026 Green Street data should focus on the spread, not the headline 5% index gain. A flat apartment sector—despite two years of cheap-money reversal—suggests supply overhang and operating-cost compression, while malls' best-in-class performance is a contrarian credit signal. These sector-level gaps matter for mortgage REITs, CMBS exposure, and private credit underwriting.

According to Green Street's July 2026 investment performance report, institutional U.S. commercial real estate has begun to recover after a four-year slump, with the firm's main property index up 5% over the twelve months ending in July. That headline, however, conceals one of the widest performance divergences in recent memory. Malls—once written off as a casualty of e-commerce—were the top-performing sector, while apartments, long treated by investors as a shortage-driven safe haven, were the only tracked niche to post flat values over the year. Green Street monitors 12 slices of institutional properties, mainly large assets controlled by major owners, so its readings speak to institutional capital rather than small private deals. The result is a commercial property market that is no longer moving as a unified asset class but as a collection of sharply differentiated risk baskets.

Office buildings remain the worst-hit, down 34% from peak, while self-storage—whose fortunes are tied to home-sale-driven relocation—is down 22%.

The divergence is rooted in the abrupt end of the Federal Reserve's low-cost financing era in 2022. Green Street's July 2026 data shows apartment values are now 19% below their 2022 peak, the third-steepest drawdown among the 12 institutional property types tracked. Office buildings remain the worst-hit, down 34% from peak, while self-storage—whose fortunes are tied to home-sale-driven relocation—is down 22%. The apartment decline is arguably the most instructive because it runs counter to a widely held supply thesis. The pandemic rental frenzy triggered a wave of overbuilding, particularly in high-end units that large operators favor. That miscalculation left numerous units empty, producing flat or discounted rents in many markets even as operating costs such as insurance and repairs soared. Rough Capitol Hill battles over housing policy in 2026 added further uncertainty for residential investors.

The past-year results invert several assumptions that have driven capital allocation since 2020. Apartment investors expected a housing-supply shortage to perpetuate rent growth and appreciation; instead, they received flat valuations at the index level and weaker pricing in many markets. Mall owners, by contrast, appear to be benefiting from years of rationalized supply, operational restructuring, and shifting consumer behavior. The report as cited identifies malls as the best performer over the twelve-month window, although it does not provide the exact appreciation figure in the available excerpts. The rehabilitation is striking for a property type that had been heavily discounted after a decade of store closures.
