Self-Storage

How it works

A self-storage facility rents individual units — climate-controlled or drive-up, in sizes from a small closet to a garage bay — under a month-to-month agreement rather than a fixed-term lease. That short duration is the mechanism that makes the business work: it lets an operator price new move-ins with a promotional rate to win the booking, then raise that tenant's rent at set intervals once they are settled in and unlikely to move again over a few dollars a month.

Demand comes from disruption in someone's life rather than from economic optimism — moving, marriage, divorce, a death in the family, downsizing, or a small business needing overflow inventory space. Because these triggers keep happening regardless of the broader economy, the sector is often described as demand-inelastic, though it is not immune to slowdowns in housing turnover.

Beyond rent, facilities sell tenant protection plans (an insurance-like product covering stored goods), boxes and locks at retail markup, and truck rental commissions; together these can be a meaningful share of total revenue. Operations lean heavily digital — search advertising drives most leads, reservations happen online, and keypad access lets a facility run with thin on-site staffing.

When a tenant stops paying, the operator does not evict in the traditional sense. Access is cut off, required notices are sent, and after the statutory waiting period the contents are auctioned under state self-storage lien law.

What it pays

Return is quoted as a cap rate on net operating income, and operating performance is tracked separately as revenue per available square foot and the percentage of net rentable square feet occupied. Because leases reset monthly, income here adjusts to inflation and local demand shifts faster than in office, industrial, or apartment property, where longer leases hold rent fixed for a year or more.

Two rates matter: the street rate quoted to a new tenant walking in today, and the in-place rate an existing tenant is actually paying after increases. The gap between them is the operator's pricing power — a wide gap signals room to keep raising in-place rents before hitting resistance, a narrow one signals a facility already priced near the market ceiling.

A newly built facility does not open full. Lease-up typically runs a couple of years before occupancy and rate stabilize, so a pre-stabilized asset is priced on projected income rather than trailing income, which shifts risk onto the buyer's forecast. Many owners hire a national brand for third-party management, paying a percentage of revenue in exchange for the brand's marketing engine, call center, and revenue management software that sets daily pricing.

Costs and taxes

Operating costs run low relative to revenue: property tax, insurance, minimal staffing, marketing, utilities, and routine repairs. Marketing is not optional overhead — visibility in local online search results is close to the main driver of who finds the facility and books a unit, so the marketing budget functions like a recurring cost of revenue rather than a discretionary expense.

For US tax purposes, the buildings depreciate over 39 years, but site components such as fencing, paving, signage, security gates, and cameras are typically shorter-lived and can be broken out through a cost segregation study, accelerating deductions in early years. Depreciation is recaptured on sale, and gain can be deferred through a 1031 exchange into another property.

Property tax appeals are common in this sector because assessors often value a facility using an income approach built on assumptions — market rent, expense ratios — that the operator disputes as too aggressive. Rental income is ordinary income; where an operator provides more than basic services (climate control, moving assistance, retail sales) at scale, how that income is characterized for REIT and passive-income tests can become more involved.

Liquidity and time commitment

Facilities trade in an active market spanning public REITs, private funds, and individual owner-operators, with smaller properties tending to sell to local buyers who self-manage. Even so, a marketed sale of a facility still takes months to close, and pricing depends on documented occupancy and rate history, not just physical condition.

Hiring third-party management brings ownership close to passive — the fee buys the marketing platform, staffing, and pricing system — while self-management turns it into an operating job covering marketing, daily rate decisions, delinquency processing, lien auctions, and physical upkeep of gates, doors, and paving.

Building new supply requires zoning entitlement, and many municipalities have restricted additional storage development along visible corridors, which shapes how easily a market can be overbuilt or protected from competition. For exposure without any of the operating role, public self-storage REITs trade daily and represent a claim on the same underlying rent-and-fee model.

How it goes wrong

Supply is the sector's defining risk. Storage is relatively quick and cheap to build compared with other commercial property, so a new facility opening within a few miles can flood a submarket with promotional rates and stall an existing operator's rate growth for years.

The same existing-customer rate increases that drive income growth eventually push tenants to leave once the gap between their rent and a competitor's promotional rate gets too wide; churn tends to rise just as an operator is counting on the rate increases to pay off, and replacing a vacated unit means starting that tenant back at a lower promotional rate.

A new facility's lease-up can run well past the projected couple of years while loan payments are due from the day the doors open, straining a deal underwritten on an optimistic timeline. Occupancy is also seasonal and tracks housing turnover broadly — when fewer people move, fewer people need a temporary place to put their belongings.

Lien sales carry real legal exposure: skipping or mistiming a required notice under state self-storage lien law can expose the operator to liability even though the tenant was genuinely delinquent. And acquisitions underwritten on today's strong street rates rather than durable, achievable in-place rates can look like a good cap rate on paper and underperform once actual renewals come in lower.
