The Income Approach Is King

Self-storage, like most commercial real estate, is valued primarily on its income-generating capacity. The dominant method is the income capitalization approach: Net Operating Income (NOI) divided by a market cap rate.

Value = NOI ÷ Cap Rate

A facility generating $200,000 in NOI in a market where comparable assets trade at a 6.5% cap rate is worth roughly $3.08 million. In 2026, stabilized Class-A facilities in the major Texas metros are trading around 5.75%–6.25%, with B-class product 75–150 bps wider — so the cap rate you apply should reflect the specific asset and submarket, not a national average.

What Is NOI?

NOI = Gross Revenue − Operating Expenses (excluding debt service and depreciation). Typical operating expenses:

  • Property taxes
  • Insurance
  • Utilities
  • Payroll or third-party management fees
  • Maintenance and repairs
  • Marketing

A well-run facility should run a 30–45% expense ratio. Above 50% usually signals operational inefficiency or revenue underperformance worth investigating.

What Drives the Cap Rate

  • Market: primary markets compress cap rates; secondary and rural markets widen them.
  • Occupancy: stabilized (90%+) trades tighter than lease-up.
  • Age & condition: newer, well-maintained assets trade tighter.
  • Climate-control mix: a higher climate-controlled percentage generally means a lower cap rate.

What Buyers Often Miss

1. Street Rates vs. In-Place Rents

Many facilities have legacy tenants paying well below market. A proforma that pushes those rents to market over 12–24 months can materially change the value conversation.

2. Expense Normalization

Owner-operated facilities frequently understate expenses (especially management). Always normalize to a 6–8% third-party management fee before applying a cap rate.

3. Physical vs. Economic Occupancy

A facility at 95% physical occupancy can have much lower economic occupancy once concessions, discounts, and delinquency are counted.
