Self-Storage KPIs.

Self-storage is a high-margin (60-70% NOI margin) commercial real estate sub-sector serving residential and small-business storage demand. Properties offer 50-2,000 SF lockable units rented monthly. Performance is measured in occupancy (physical + economic), revenue per square foot, RevPAU (Revenue Per Available Unit), street rate vs in-place rate spread (ECRI — Existing Customer Rate Increase), and average length of stay. The sector is dominated by four public REITs (PSA, EXR, CUBE, NSA) that collectively own ~25% of US self-storage. Demand drivers: housing transitions, downsizing, small business inventory, and new-home/dorm cycles. Ilora.ai ingests rent roll (current + waitlist), occupancy reports (physical + economic), ECRI tracking, move-in/move-out reports, and length-of-stay distribution, then benchmarks ECRI deployment cadence and RevPAU trends against Public Storage (PSA), Extra Space (EXR merged Life Storage 2023), CubeSmart (CUBE), and National Storage Affiliates (NSA) peer data.

NOI

Net Operating Income

Total revenue minus operating expenses (excludes financing and capital costs). The primary measure of property-level profitability.

NOI = Revenue − Operating Expenses

  • profitability
  • core
Cap Rate

Capitalization Rate

Net Operating Income divided by current property value. Expresses unleveraged annual yield as a percentage.

Cap Rate = NOI ÷ Property Value

  • valuation
  • core
DSCR

Debt Service Coverage Ratio

Net Operating Income divided by total annual debt service. Lender-required cushion measure; below 1.0 means NOI cannot cover debt.

DSCR = NOI ÷ Annual Debt Service

  • lending
  • risk
LTV

Loan-to-Value

Loan amount divided by property value. Lower LTV = lower lender risk.

LTV = Loan Amount ÷ Property Value

  • lending
  • risk
OER

Operating Expense Ratio

Operating expenses divided by gross revenue. Lower is better, but varies by property type (hotels run higher than triple-net retail).

OER = Operating Expenses ÷ Gross Revenue

  • efficiency
GRM

Gross Rent Multiplier

Property value divided by gross annual rental income. Quick valuation shortcut; less precise than cap rate.

GRM = Property Value ÷ Gross Annual Rent

  • valuation
  • shortcut
IRR

Internal Rate of Return

Annualized return on investment accounting for time value of money across the full hold period.
  • return
  • underwriting
CoC

Cash-on-Cash Return

Pre-tax annual cash flow divided by total cash invested. Measures the cash yield, not total return.

CoC = Annual Cash Flow ÷ Total Cash Invested

  • return
DCF

Discounted Cash Flow

Valuation method that projects future cash flows and discounts them to present value at a chosen rate.
  • valuation
  • underwriting
TTM

Trailing Twelve Months

A rolling sum of the most recent 12 months. Smooths seasonality for KPI comparisons.
  • period
  • core
PUE

Power Usage Effectiveness

Total facility power divided by IT equipment power. Lower is better — 1.0 is theoretical perfect.

PUE = Total Facility Power ÷ IT Equipment Power

  • data_center
  • efficiency
SF Yield

Square Foot Yield

NOI per rentable square foot. Comparable measure across industrial buildings of different size.
  • efficiency
Clear Height

Clear Height

Distance from finished floor to lowest overhead obstruction. Drives storage cube and rent premium.
  • physical

Sub-types

Sub-types within Self-Storage.

Class A Climate-Controlled
Multi-story climate facility, urban infill, premium pricing.
Class B Drive-Up
Single-story outdoor drive-up units, suburban location.
Industrial Conversion
Adaptive reuse of warehouse / retail box; common in low-cost-basis acquisitions.
Boat / RV Storage
Outdoor uncovered, covered, or enclosed parking for vehicles.

Frequently asked

Common questions about self-storage.

What is ECRI in self-storage?
ECRI (Existing Customer Rate Increase) is the practice of raising rates on in-place customers — typically 5-15% per increase, 1-2 times per year — to capture the gap between street rate (new-customer pricing) and in-place rate. Public REITs (PSA, EXR, CUBE, NSA) report ECRI revenue contribution quarterly. ECRI is the largest organic NOI growth lever for self-storage; tenants rarely move out for a 10% increase given the cost + hassle of relocating units.
How profitable are self-storage facilities?
Self-storage NOI margins typically run 60-70% — among the highest in commercial real estate — driven by minimal labor (often single-employee facilities or unmanned automated kiosks), low non-recoverable expenses, and high-margin ancillary income (insurance, retail). Public REITs (PSA, EXR) report consistent 60%+ margins. Compare to multifamily (45-50%), office (50-55%).
