Self-storage earned its reputation as a “recession-resistant” real estate asset class during the 2008-2010 downturn, when demand held up better than most commercial real estate as people downsized homes and needed somewhere to put their belongings. That reputation drove a wave of institutional capital into the sector over the following decade. Here’s where the market actually stands now, and what it means for someone evaluating a self-storage investment.
The Supply Story: From Undersupplied to Locally Oversupplied
The defining dynamic of the last several years has been a construction boom correcting what was, through the 2010s, a genuinely undersupplied asset class in most metros. That boom pushed new supply into many mid-size and secondary markets faster than population and household-formation growth could absorb it, and it shows up directly in occupancy and street-rate data: many operators have reported softer same-store rental rates and higher promotional discounting to fill new and existing units compared to the unusually strong pricing power of 2020-2022, when pandemic-driven moving and decluttering spiked demand simultaneously.
This is a market where the national narrative and the local reality diverge more than most real estate sectors. A metro with constrained new construction (due to zoning restrictions on self-storage specifically, which many municipalities have tightened) can still show strong rent growth while a metro that permitted a wave of new facilities sees flat-to-negative same-store performance. Underwriting a specific facility on national self-storage headlines, rather than that facility’s actual three-mile competitive supply radius, is the single most common mistake new investors make in this asset class.
Demand Drivers That Persist Regardless of Cycle
- Life-event demand. Moving, downsizing, divorce, death of a family member, military relocation — a meaningful share of self-storage demand isn’t discretionary and doesn’t disappear in a downturn the way, say, boat storage might.
- Small business and inventory storage. E-commerce sellers, contractors, and small businesses without warehouse space are a growing tenant category for many facilities, and this demand source is less seasonal than pure residential decluttering.
- Housing mobility and smaller living spaces. As home sizes trend down in many new-construction markets and renters increasingly occupy smaller units, storage becomes a substitute for the garage or basement they don’t have.
What’s Changed for Underwriting
| Factor | 2020–2022 environment | Current environment |
|---|---|---|
| Street rates | Rapid growth, low discounting | Flat to declining in oversupplied metros, heavier promotional discounting |
| Cap rates | Compressed, aggressive institutional buying | Wider, more buyer discipline on price |
| New supply | Under construction, not yet delivered | Delivering and leasing up in many secondary metros |
| Underwriting focus | Portfolio-level trend extrapolation | Facility-level, radius-specific supply analysis |
How to Evaluate a Specific Deal Today
Pull the actual competitive supply within roughly a three-to-five-mile radius, including facilities under construction or recently permitted — not just currently operating ones. Look at trailing 12-month occupancy and net rental rate (street rate minus discounts/concessions actually being given), not just the advertised rate. Stress-test the pro forma against a scenario where a new competing facility opens nearby within the hold period, since that’s a live risk in many markets rather than a tail scenario. Non-climate-controlled unit demand and climate-controlled unit demand can diverge significantly by market — don’t assume national climate-controlled premium data applies locally without checking.
FAQ
Is self-storage still a good asset class to enter now? It depends heavily on the specific market and facility, more than it did five years ago when broad tailwinds lifted most properties. Markets with constrained new supply and durable population/household growth remain attractive; markets that saw a construction wave need a longer lease-up runway priced into the deal.
How does self-storage compare to multifamily for a first-time real estate investor? Self-storage generally has lower operating complexity (no tenant habitability issues, shorter and simpler leases) but historically thinner third-party financing availability and a smaller pool of comparable sales data for underwriting than multifamily.
Do climate-controlled units always command a premium worth the extra construction cost? Not universally — it depends on local climate, competing supply’s mix of climate-controlled vs. standard units, and tenant mix (household goods tenants value it more than vehicle/boat storage tenants).
Verdict
Self-storage hasn’t stopped being a fundamentally sound asset class, but the era of “any facility in any market” outperforming almost automatically is over. The dividing line now runs through local supply discipline, not the sector broadly — investors doing facility-specific, radius-level underwriting will keep finding good deals; investors extrapolating from national self-storage headlines are the ones getting caught by local oversupply.
