For accredited investors, we believe that self-storage facilities should be a part of any diversified real asset portfolio. Its low correlation with stocks and other commercial properties enhances diversification, while its income generation can help support total return goals. Self-storage is proving itself to be a strategic real estate investment, far more than simply a niche alternative.
How It Began
Self-storage addressed a simple problem. People needed space for their belongings. It didn’t start as a sophisticated investment. What local entrepreneurs built with limited capital decades ago has evolved into a durable, high-demand property type. Today, many REITs, private equity firms, and family offices are attracted to this type of facility that aims to deliver steady cash flow and long-term demand.
For investors evaluating real assets, self-storage offers a rare combination of operational simplicity and consistent performance across market cycles.1
The self-storage industry took off in the 1960s in Texas and the Southwest, where many homes lacked basements or extra storage space. Developers responded by building single-story buildings divided into lockable units that were accessible to renters.2
The business model gained wider attention in the early 1970s when Public Storage was founded in 1972 by B. Wayne Hughes and Kenneth Volk Jr. in El Cajon, California. They launched their first facility with $50,000, recognizing the growing demand for secure storage, and they reinvested cash flow to expand. 3
Early success stemmed from a key insight: storage facilities generate attractive margins with far less operating complexity than apartments or office buildings do.
For years, the sector stayed highly fragmented. Local banks financed facilities, individual operators owned them, and institutional capital largely ignored the space. Development stayed tied to local demand, not market cycles. 3
Where the Industry Is Today
Now, the self-storage business is mainstream. The U.S. hosts over 50,000 facilities totaling more than 2 billion square feet of rentable space. 4
Institutional investors have entered the arena in a big way. Publicly traded REITs like Public Storage, Extra Space Storage, CubeSmart, and National Storage Affiliates now control a significant market share. Private equity firms, including KKR, Brookfield, and Cerberus, have stakes, and syndicated offerings give investors easier access as well.
Self-storage has continued to deliver strong returns relative to other commercial property types. Industry data show the sector can produce income yields exceeding 17%, roughly five percentage points higher than its nearest real estate competitor, while appreciating with lower volatility than office, retail, or hospitality assets.5 Credit performance reinforces that strength. As of September 2025, CMBS delinquency rates for self-storage loans stood at approximately 0.1%, compared with an average of 6.6% across all commercial property types.6
That combination of operational simplicity, recurring cash flow, and downside protection has drawn attention well beyond institutional real estate circles. Rick Harrison, best known for Pawn Stars and a long-time self-storage investor, has described the sector as “one of the most recession-resistant businesses there is,” noting that demand tends to persist regardless of economic cycles because people rarely stop accumulating belongings or needing a place to store them.
Market-level data continues to support that view. In Washington, D.C., for example, rental income has increased by approximately 15.4% as new supply has moderated. While performance can vary by cycle and market, industry analysts report stabilizing fundamentals and improving rent revenues on a year-over-year basis at many large operating platforms, reinforcing the importance of disciplined underwriting and careful local market selection. 7
Just as in other industries, operators are leveraging technology to boost margins: online leasing, dynamic pricing, automated access, and centralized management. They also generate extra revenue from tenant insurance, packing supplies, and premium climate-controlled units for wine or collectibles
Location and Demand
No matter how sophisticated the market has become, it still matters where these are located. Population growth, housing turnover, and mobility strongly influence storage demand. The Sun Belt, with its expanding population, supports expansion, while coastal markets benefit from zoning restrictions and limited new supply. Take Boston, MA: the city and metro area have tight, complex zoning rules, and, with over 50 colleges, universities, and 250,000+ students, there is high demand for undergrads who need temporary storage over the summer. 8
Several fundamental reasons continue to fuel demand:
- High household mobility: Remote work and changing employment patterns prompt relocations, particularly in the Sun Belt.
- Life-stage storage needs: Roughly 11% of Baby Boomers use self-storage as they downsize. Meanwhile, millennials now represent roughly 35% of self-storage renters, managing housing constraints.9
And there’s likely a psychological aspect to consider:
“Human laziness has always been a big friend of self-storage operators,” says Derek Naylor, former president of Storage Marketing Solutions. “Once they’re in, nobody likes to spend all day moving their stuff out. As much as they can afford it… they’ll leave it there forever.” 10
Investment Options
Investors can access self-storage in multiple ways:
- Direct ownership & joint ventures: Offers control and upside but requires hands-on management.
- Public REITs: Provide liquidity and diversification but expose investors to broader equity market movements.
- Private syndications & closed-end funds: Combine current income with long-term equity upside.
- Debt investments: Provide income with reduced downside risk, secured by self-storage assets.
Self-storage behaves differently from many other real estate assets. Among its unique features, most leases are month-to-month, letting operators adjust rents quickly in changing market conditions, a major advantage during inflation or economic uncertainty.
When evaluating opportunities, investors should focus on local supply, square feet per capita, barriers to entry, and development pipelines. Overbuilding remains the key risk. Facility quality matters, too: modern security, climate control, and convenient access boost rents and tenant retention.
An Investment Outlook
Self-storage has grown from a practical solution into a proven real estate asset. It is supported by life-event-driven demand, operational flexibility, and resilience across market cycles. Demographic shifts, mobility trends, and constrained supply in many markets continue to support performance, while short-term leases and scalable operations allow owners to adapt quickly to changing conditions. As Robert Moser, Founder and CEO of Prime Group Holdings, notes, “As a recession-resilient, need-based asset, self-storage offers its investors reliable cash flow with very little downside, plus multiple proven methods of creating value post-acquisition.” 11 For those seeking income, diversification, and risk management, self-storage has earned its place as a strategic component of a modern real asset portfolio.
