Self storage continues to reinforce its position as one of commercial real estate’s most resilient and closely watched asset classes. While the sector benefited from extraordinary pandemic-era demand, today’s market is increasingly defined by institutional investment, disciplined operations, and evolving valuation considerations.

The scale of recent activity highlights the sector’s continued appeal. According to Connect CRE , Public Storage recently announced a planned $10.5 billion acquisition of National Storage Affiliates , a transaction involving more than 1,000 properties and 69 million rentable square feet across 37 states and Puerto Rico. The deal underscores how institutional investors continue to view self storage as a long-term growth sector.

Capital markets activity tells a similar story. In April 2026, Talonvest Capital arranged $64 million in refinancing for a five-property Southern California portfolio totaling more than 344,000 rentable square feet. Talonvest cited strong occupancy, durable cash flow, and favorable supply-demand fundamentals as drivers behind the financing structure, which included long-term, fixed-rate, interest-only debt.

At the property level, investors continue targeting urban infill markets with constrained supply and population growth. North Palisade Partners’ recent acquisition of a Class-A self-storage portfolio in Philadelphia’s Northern Liberties neighborhood reflects this strategy. According to the company, the area benefits from strong multifamily development, increasing density, and limited existing storage supply.

At the same time, the sector is transitioning from the explosive growth experienced during the pandemic into a more normalized operating environment. CRE Daily recently reported that rent growth and occupancy levels are stabilizing after several years of exceptional performance, shifting greater emphasis toward operational efficiency and local market fundamentals.

Even with this normalization, self storage has maintained an impressive long-term performance profile. According to the Pension Real Estate Association (PREA), self storage has historically ranked among the top-performing sectors within the NCREIF Property Index (NPI), outperforming most traditional property types nearly 40% of the time over trailing annual periods. PREA also reports that public-sector self-storage investments have generated an average annual total return of 14.9% since 1993, outperforming the second-highest sector by approximately 370 basis points.

Self storage’s role within institutional investment benchmarks has expanded significantly over time. NCREIF added self storage to the NPI in 2005 as part of its inclusion of alternative asset classes. According to PREA, the sector grew from just four properties valued at $183 million in 2002 to more than 1,090 properties valued at approximately $23.6 billion in recent years.

For appraisers, these trends reinforce the importance of understanding local demand drivers, financing conditions, lease-up dynamics, and operational performance. As institutional participation grows and market conditions become more nuanced, broad assumptions are giving way to more data-driven analysis.

To support that work, the Appraisal Institute’s Self Storage Economics and Appraisal, Second Edition, provides updated methodologies and market insights for analyzing self-storage assets in today’s environment.

Appraisers can also supplement their analysis with industry benchmarking tools such as the 2026 Self-Storage Almanac and the 2026 Self-Storage Expense Guidebook , both available to Appraisal Institute members at a discount using promo code 2026APP20.
