Self-storage is one of the most consistently attractive acquisition categories for small business buyers. High occupancy rates, low labor requirements, minimal inventory, resilient demand across economic cycles, and strong SBA financing eligibility attract both experienced and first-time acquisition buyers. This guide covers what to evaluate when analyzing a self-storage facility.
Occupancy Analysis
Physical vs. Economic Occupancy: Physical occupancy (percentage of units rented) and economic occupancy (percentage of potential revenue being collected) can diverge significantly. A facility may show 92% physical occupancy but 85% economic occupancy if a significant portion of tenants are on promotional rates, delinquent, or have partial-month prorations. Economic occupancy is the more accurate measure.
Street Rate vs. In-Place Rate: The street rate (current asking price for new rentals) may differ from in-place rates (what current tenants actually pay). A facility that has raised rates for new customers but not pushed increases to existing long-term tenants has embedded revenue opportunity — but also means reported revenue understates potential at full street rates.
Occupancy Trend: Request monthly occupancy data for 24-36 months. A facility at 90% that was at 95% two years ago has a declining trend the current snapshot doesn't show.
Revenue Per Square Foot
Revenue per rentable square foot normalizes for facility size and allows comparison against market benchmarks. Calculate total annual revenue divided by total rentable square footage. A facility generating $8/sq ft annually in a market where competitors generate $12/sq ft has either a pricing problem or a quality/location problem — and the answer has significant valuation implications.
Cap Rate and Valuation
Self-storage facilities are valued on a cap rate basis applied to NOI — the same method used for commercial real estate.
| Market Type | Cap Rate Range | Multiple on NOI |
|---|---|---|
| Primary markets — stabilized | 4.5% – 6.0% | 16x – 22x |
| Secondary markets — stabilized | 5.5% – 7.5% | 13x – 18x |
| Tertiary markets — stabilized | 6.5% – 9.0% | 11x – 15x |
Operational Due Diligence
- Unit-level rent roll — every unit, size, rate, move-in date, and status
- Monthly occupancy history for 24-36 months
- Delinquency report — units past due and amount outstanding
- Property condition report — roof, drainage, security systems, gate systems
- Environmental assessment — Phase I at minimum
- Competitive supply analysis — new facilities planned or under construction nearby
Red Flags
- High delinquency rate (more than 3-5% of tenants past due)
- Occupancy declining over the past 12-24 months
- New self-storage supply entering the market nearby — oversupply is the primary risk
- Environmental issues on the property
Frequently Asked Questions
On a cap rate basis applied to NOI. The cap rate varies by market quality — typically 5-8% for most markets, resulting in multiples of 12x-20x NOI. This is a real estate valuation methodology, not an EBITDA multiple approach.
Yes — self-storage with real estate is well-suited for SBA 7(a) and 504 programs. Clear collateral, documentable income, and extensive SBA lender familiarity with the asset type.
