Insurance is often viewed as a necessary operating expense, something a self-storage owner pays each year to protect the property and satisfy lender requirements.
But insurance costs can affect more than the facility’s annual budget.
Because insurance premiums are included in operating expenses, reducing that expense may improve net operating income, commonly referred to as NOI. And because self-storage facilities are often valued using a capitalization rate, even a modest improvement in NOI may have a meaningful impact on the facility’s estimated value.
How Insurance Savings Affect NOI
Net operating income represents the income a property generates after operating expenses are deducted, but before debt payments, income taxes, depreciation and certain capital expenses.
When an operating expense decreases and everything else remains equal, NOI increases by the same amount. For example, suppose a self-storage operator reduces annual insurance expenses by $50,000. That $50,000 expense reduction may result in a $50,000 increase in NOI.
The next step is to understand how that improved NOI may affect the facility’s valuation.
Turning NOI Into Facility Value
A capitalization rate, or cap rate, is commonly used to estimate the value of an income-producing property.
NOI ÷ Cap Rate = Estimated Facility Value
Using the previous example, a $50,000 NOI increase at a 6% cap rate would produce the following result:
$50,000 ÷ 0.06 = $833,333
In this example, reducing annual insurance expenses by $50,000 could represent an illustrative increase in facility value of approximately $833,000.
The impact becomes even more meaningful across a larger portfolio.
These figures are illustrations only. Actual property values depend on market conditions, cap rates, financial performance, property characteristics and many other factors.

Why Owners Should Regularly Review Insurance Expenses
Insurance markets change over time. So do self-storage facilities.
An operator may acquire new properties, renovate buildings, replace roofs, add climate-controlled units, install security systems or change how the facility is managed. Construction costs, carrier appetite, deductibles and coverage requirements may also change.
However, insurance programs are not always reviewed with the same attention owners give to rental rates, occupancy, payroll, property taxes and other operating expenses.
A comprehensive insurance review may help determine whether:
- Property values and limits remain accurate
- Deductibles align with the owner’s risk tolerance
- Coverage is consistent across the portfolio
- Business income limits reflect current operations
- New improvements or acquisitions are properly scheduled
- The facility is benefiting from available carrier options
- Premium costs remain competitive
The Lowest Premium Is Not Always the Best Result
Reducing insurance costs can be valuable, but premium should never be evaluated by itself.
A lower-cost policy may include higher deductibles, narrower coverage, restrictive exclusions or insufficient limits. These differences could expose the operator to significant financial loss when a claim occurs.
The goal should be to identify the best overall insurance structure for the facility—not simply the lowest available price.
Owners should compare:
- Property limits
- Replacement cost provisions
- Wind and hail deductibles
- Named-storm deductibles
- Flood and earthquake exposure
- Business income coverage
- General liability coverage
- Customer goods legal liability
- Sale and disposal liability
- Cyber coverage
- Carrier financial strength
- Claims service and advocacy
Meaningful savings should strengthen the investment without weakening the protection surrounding it.
Insurance Considerations Before Buying a Facility
Buyers should avoid assuming that a seller’s existing insurance premium will remain available after an acquisition.
The buyer’s ownership structure, claims history, portfolio size, financing requirements and planned improvements can all influence coverage and pricing.
Obtaining an insurance indication early in the acquisition process may help buyers:
- Build more accurate operating projections
- Identify difficult property characteristics
- Understand lender coverage requirements
- Avoid unexpected expenses before closing
- Evaluate the transaction using more reliable NOI assumptions
An unexpected premium increase late in the transaction could materially affect projected returns or debt-service coverage.
Insurance Considerations Before Selling or Refinancing
Owners preparing to sell or refinance may also benefit from reviewing insurance costs in advance.
If an insurance review identifies responsible savings without sacrificing coverage, the resulting improvement in NOI may help strengthen the facility’s financial presentation.
It may also allow the owner to address inaccurate property information, outdated valuations or coverage concerns before they are identified by a buyer, lender or due diligence team.
Insurance Through an Owner’s Lens
Insurance is not only about satisfying a contractual requirement or responding to a claim.
For self-storage operators, it is also part of the facility’s broader financial and risk-management strategy.
Johnson Insurance specializes in self-storage and brings industry experience in facility ownership, management, lending and construction to the insurance conversation. That perspective allows our team to evaluate both the protection of the property and the financial impact of the insurance program.
A thoughtful review may help uncover opportunities to improve coverage, reduce unnecessary expenses and better support the long-term value of the facility.
Take a Deeper Look at Insurance and Facility Value
Insurance can affect more than annual premium expense. Coverage structure, claims history, business-income protection, property values, deductibles and lender requirements can all influence a facility’s financial performance and transaction readiness.
Johnson Insurance created the Self-Storage Insurance Value Guide to help self-storage owners, operators, buyers, brokers and industry professionals better understand where insurance and facility value intersect.
The guide explores:
- How insurance expense can affect NOI and estimated facility value
- Business-income coverage and recovery after a loss
- Replacement-cost accuracy
- Wind and named-storm deductibles
- Uninsured or underinsured property exposures
- Claims history and future insurance options
- Transaction and lender requirements that can affect a closing
- It also includes practical questions and considerations to review before a renewal, acquisition, refinance or sale.

What Is Your Insurance Costing Your Facility?
A change in insurance expenses can affect more than the next renewal invoice.
It may influence NOI, acquisition underwriting, refinancing decisions and the estimated value of the facility.
