How to Value a Self-Storage Facility

Self-storage is the darling of the boring-business world: minimal staff, sticky tenants, and pricing power. Multiples run higher than most Main-Street businesses, and facilities are often valued on a cap rate as much as on SDE.

What SDE is — and why this industry is priced on it

Small, owner-operated businesses are almost never priced on revenue. They are priced on SDE (Seller's Discretionary Earnings)— the total cash a single owner-operator takes home. You start with net profit and add back the owner's salary, personal perks run through the business, one-time costs, interest, and depreciation. SDE is then multiplied by an industry multiple to estimate enterprise value.

Self-storage can be valued two ways: as a business on an SDE multiple, and as real estate on a cap rate (net operating income ÷ value). SDE multiples run high because labor is low and tenants rarely move out over a few dollars. Occupancy, street rates, and rate-management discipline drive the number.

The real multiple range for self-storage

These are the curated rule-of-thumb ranges this site uses across its calculator and AI analyzer — drawn from BizBuySell Insight Report + BVR/Business Reference Guide broker rules-of-thumb, 2024–2025. Treat them as a comp range to anchor a price, not an appraisal.

Often valued on cap rate; SDE multiples run high due to low labor and sticky tenants.

Worked examples

The math is simply SDE × multiple. Three examples across the range:

A business at the typical 6× multiple on $350,000 of SDE works out to $2,100,000. You can run your own number — and see the full low/typical/high range — in the free valuation calculator.

What pushes the multiple up

High and stable occupancy, active rate management (regular existing-tenant rate increases), automated kiosks/online rentals that cut labor, ancillary revenue (insurance, retail, truck rental), low delinquency, and room to add units or convert to climate-controlled space. Because real estate is usually included, location and land value matter a lot.

Risks & red flags that drag it down

A nearby competitor or a wave of new supply can cap rates and crush rate growth. Watch for owners who have never raised existing-tenant rates (under-monetized, but also a one-time fix), deferred maintenance on roofs and doors, weak management software, and overstated occupancy that doesn't reconcile to the rent roll.

Verify before you anchor on a price

Get the rent roll and the management-software reports, and verify both physical occupancy (units full) and economic occupancy (units paying). Confirm street rates versus in-place rates to gauge upside, and treat the facility as real estate too — get the property condition and the cap rate comps.

Is it a good acquisition? The SOWS lens

Beyond price, ask whether it's a good buy. The SOWSframework (popularized by Codie Sanchez) scores a deal on whether it's Stale (outdated marketing/ops you can modernize), Old (a long-tenured, motivated seller often open to financing), Weak (under-optimized systems and pricing you can fix), and Simple (a model you can actually run).

Self-storage scores beautifully on SOWS: many facilities are run by an Old owner who never raised rates (Weak), with no online rental and dated signage (Stale), in a model that's about as Simple as it gets. The catch is price — strong fundamentals mean sellers know what they have, so multiples are high.

Structure the offer, not just the price

Price is only half the deal. A seller note keeps the seller invested in a clean handoff and lowers your cash to close; an SBA 7(a) loan can fund the rest. When you have a real listing, run the full deal — valuation, SOWS score, multiple sanity-check, and a seller-financed offer — through the AI Deal Analyzer.
