Self-storage underwriting

Self-storage is the most recession-resistant real-estate asset class — life events (moves, divorces, downsizing) drive demand in both expansion and recession. The opportunity is buying mom-and-pop facilities at 7–9% cap and adding revenue management software to push rent 8–12% in 18 months.

NOI = (units × rent × 12 × occupancy) − opex. Cap rate = NOI ÷ price. CoC = (NOI − debt service) ÷ equity.

Why self-storage is the income REIT category

Three structural moats compound: (1) low operating costs (no staff if automated), (2) sticky tenants (avg stay 14+ months), (3) frequent CPI-linked rent increases (most operators raise 6 months after move-in). Public Storage has compounded at 14%+ for 30 years — and the math at the unit level shows why.

The value-add playbook (mom-and-pop arbitrage)

The opportunity isn't buying REIT-quality assets at 6% cap — it's buying owner-operated facilities at 8% cap and applying basic revenue management.

  • Implement dynamic pricing software (Storage Asset Management, SiteLink) — typical 8–12% revenue lift in 12 months.
  • Raise existing tenant rents 8–10% annually after month 6 (REIT standard, owner-operators rarely do).
  • Add tenant insurance markup ($12/mo × 70% take rate = $8/unit/mo of pure margin).
  • Compress opex ratio from 40%+ down to 32–35% by going on-site staff → remote management.

Financing: SBA 504 vs conventional CRE

SBA 504 is uniquely structured for self-storage: 10–15% down, blended 25-year amortization at SBA + CDC + bank tranches, no balloon. Conventional CRE wants 25–35% down with 5-year balloons. SBA 504 is almost always the right answer for facilities under $5M.

FAQ

Are self-storage facilities profitable?

Yes — the most consistently profitable real estate asset class. Stabilized facilities run 60–68% NOI margins and 8–15% cash-on-cash with SBA financing. Self-storage REITs have outperformed every other REIT sector over the past 30 years.

How much does a self-storage facility cost?

Tertiary market mom-and-pop facility: $1–3M. Mid-market metro B-class: $4–10M. Primary metro A-class: $10–40M. SBA 504 financeable at 10–15% down up to $5M with the SBA portion; larger deals require conventional CRE financing or partners.

What's a good cap rate for self-storage?

Primary metro REIT-quality: 5.5–7.0%. Mid-market B-class: 6.5–7.5%. Tertiary market: 7.5–9.5%. Value-add opportunities can underwrite at higher cap rates with explicit operational upside.

How do I value a self-storage facility?

Value = stabilized NOI ÷ market cap rate. Get T-12 (trailing 12 months) financials, normalize them (add back owner perks, deduct any non-recurring revenue), and apply the local market cap rate. Adjust for occupancy: anything under 85% gets discounted for ramp risk.
