Commercial Real Estate Portfolio Insurance:
What Coverage Does Your Portfolio Actually Need?

A blanket property policy covers multiple properties under a single combined limit — rather than assigning separate limits to each building. For portfolios of roughly five or more commercial properties, a blanket structure typically offers better coverage flexibility and can be more cost-effective than insuring each property individually.

The key advantage is that if a loss at one property exceeds what its individual limit would have been, the blanket limit can absorb the overage — as long as total losses don't exceed the blanket amount. Blanket policies also simplify administration when acquiring or disposing of properties, since you're adjusting a schedule rather than binding entirely new policies. An agreed-amount or margin clause can further protect you from coinsurance penalties on individual properties within the blanket.

Loss of rents for commercial properties is typically calculated based on actual rental income from current lease terms, not market-rate estimates or residential rental comparables. The calculation accounts for the gross rental income you would have collected during the restoration period — the time needed to repair the property and re-lease to tenants.

For CRE portfolios, several factors complicate the calculation: net vs. gross lease structures affect what income is actually at risk, tenant improvement obligations may create additional expenses during restoration, CAM (common area maintenance) recovery gaps can compound the loss, and the realistic re-leasing timeline in your specific market affects how long the income interruption lasts. We work from your actual rent roll and lease abstracts to set limits that reflect your real exposure.

Coinsurance is a policy provision that requires you to insure your property to a specified percentage of its replacement cost — typically 80%, 90%, or 100%. If your insured value falls below that threshold at the time of a loss, the carrier can reduce the claim payment proportionally using a penalty formula.

For CRE portfolios, this is particularly dangerous because replacement costs change over time with construction cost inflation, building code changes, and tenant improvements — and undervaluation at one or two properties in a blanket can trigger penalties across the board. The remedy is an agreed-amount endorsement, which eliminates the coinsurance penalty in exchange for the carrier agreeing that your stated TIV is sufficient. We recommend agreed-amount provisions for every portfolio program we build.

In most cases, no. A blanket general liability policy can cover premises liability across all properties in your portfolio under a single policy with consistent limits. This is more efficient than individual policies and eliminates the risk of a gap between separately insured locations.

There are situations where a tenant's lease may require you to carry specific limits or name them as additional insured on a per-location basis — and blanket GL programs can accommodate this through endorsements or scheduled additional insureds. The umbrella or excess layer sits above your blanket GL and provides additional capacity across the entire portfolio. We structure the liability program to meet the most stringent tenant or lender requirement across your portfolio so every property is covered to the highest standard.

CRE portfolio insurance premiums vary widely based on total insurable value, property types, construction classes, geographic spread, loss history, and occupancy types. We build programs around your actual portfolio rather than applying generic rate tables.

The primary cost drivers are: total insurable value (TIV) across all properties, construction class and age of each building, geographic concentration and natural catastrophe exposure (coastal, wind, flood, earthquake zones), loss history over the past 3-5 years, occupancy types and tenant mix, and the deductible structure you select. Portfolios with newer construction, fire-resistive buildings, and clean loss histories typically access the most competitive rates. Older portfolios with frame construction or mixed-hazard tenants require more specialized placement.

Tenant improvement and betterment (TI&B) coverage protects the value of improvements made to a leased space — built-out offices, custom retail fixtures, specialized HVAC, or structural modifications. Whether the landlord or the tenant is responsible for insuring TI&B depends on the lease.

As a CRE portfolio owner, your lease terms typically define who carries TI&B risk. In many commercial leases, the landlord is responsible for insuring the base building and any landlord-funded improvements, while the tenant insures their own improvements. However, some leases shift TI&B responsibility to the landlord entirely. We review your lease language to ensure TI&B is covered by the right party and that no gap exists between what your property policy covers and what your tenants are insuring.
