Self-Storage Investment Thrives Amid Consolidation, Cap Rates Shift
By Majid Radaei, RadCRE · · Industry Insights
Despite economic headwinds, self-storage demonstrates robust performance, with cap rates stabilizing nationally around 5.5% as major players like Public Storage pursue strategic acquisitions.
Self-Storage Sector Maintains Resilience Amidst Macroeconomic Shifts
The self-storage sector continues to defy broader commercial real estate trends, exhibiting remarkable resilience and attracting significant institutional capital. While some asset classes grapple with higher interest rates and tightened lending conditions, self-storage benefits from its low operating costs and demand drivers linked to life events, proving its defensive characteristics. This stability has fueled ongoing investment activity and strategic consolidation, even as cap rates have seen modest adjustments from their pandemic-era lows.
Cap Rate Dynamics and Investment Volumes
According to data from MSCI Real Assets (formerly RCA), national average self-storage cap rates, after compressing significantly in 2021 and early 2022, have largely stabilized. While prime assets in Tier 1 markets might still trade in the low 5% range, the national average in Q4 2025 hovered around 5.5% for Class A properties, reflecting a slight moderation from the sub-5% averages observed during the peak of the investment frenzy. Transaction volumes, while down from the record highs of 2021-2022, remain robust, driven by a consistent capital allocation to the sector. CBRE's Q4 2025 Self-Storage Report indicated that despite a 20% year-over-year decline in total transaction volume from its peak, the sector still significantly outperformed other retail and office segments.
Consolidation Continues Amongst Major REITs
Consolidation remains a defining characteristic of the self-storage landscape. Major publicly traded REITs are leveraging their balance sheets and access to capital to acquire smaller, independent operators and strategic portfolios. Public Storage (NYSE: PSA), for instance, has been particularly active. In late 2025, Public Storage announced the acquisition of 56 self-storage properties across 14 states for approximately $1.6 billion, expanding its footprint significantly. This follows their earlier 2025 acquisition of Simply Self Storage for $2.2 billion, adding 120 properties. These moves illustrate the trend of larger players seeking economies of scale and market dominance in a fragmented but growing market. Similarly, Extra Space Storage (NYSE: EXR) also continues its strategic expansion, often through joint ventures and programmatic acquisitions targeting Class A assets in high-growth submarkets.
Our Take: Strategic Opportunities in a Maturing Market
Majid Radaei, Founder of RAD Commercial Realty, notes, "The self-storage sector, while maturing, still presents compelling opportunities, especially for investors willing to look beyond core, stabilized assets. While the days of aggressively compressed cap rates are likely behind us, the sector's defensive nature makes it attractive in a volatile economic climate. We're advising clients to focus on value-add opportunities in secondary and tertiary markets where demand drivers – such as population migration or new housing developments – are strong but institutional competition is less fierce. Furthermore, understanding the nuances of local market supply and demand, alongside the operational efficiencies that can be gained through technology integration, is paramount. For investors looking at acquisitions in this space, our RadCRE.ai platform provides granular underwriting to identify these precise opportunities, optimizing capital stacks that may involve bridge financing (currently SOFR + 300-600 bps) for acquisitions with a clear value-add strategy, or more favorable portfolio financing for stabilized assets."
Future Outlook and RadCRE's Role
The self-storage sector is expected to maintain its stability, supported by continued demand and strategic expansion by well-capitalized operators. While new supply could pressure occupancy and rental growth in some micro-markets, the sector's adaptability and relatively low operating leverage position it favorably for long-term investors. RadCRE assists clients in navigating this dynamic market, providing comprehensive investment sales advisory and financing solutions, from identifying suitable self-storage acquisition targets to structuring optimal capital stacks that align with their investment objectives.
