Before you decide
- Location diversity and insurance diversity are different.
- Several buildings can share one event, system, vendor or limit.
- Assign every unresolved issue to an owner and review date.
Create the portfolio register
Use one row per building, not only one row per policy. Record address, actual jurisdiction, entity, uses, values, monthly income, key systems, insurer, limits, deductibles and dates. Reconcile the register to contracts and current operating records.
Download the blank portfolio review CSV. It contains headers and empty fields only. Complete it privately, keep source documents alongside it and avoid putting tenant personal information in the register.
Map concentration
| Shared dependency | Stress question | Evidence |
|---|---|---|
| Nearby buildings | Could one storm affect several deductibles? | Locations and event terms |
| One mechanical system | How many leases stop if it fails? | Equipment and continuity plan |
| One manager/vendor | Who acts if that provider is unavailable? | Backup authority and contacts |
| One insurance program | Which limits or aggregates are shared? | Full program wording |
| One payment/data system | Can the business operate during an outage? | Recovery and vendor arrangements |
Run a simultaneous-event scenario
Illustrative portfolio: four nearby properties each have a $5,000 applicable per-building deductible. If the contract applies all four to one event, deductible exposure is $20,000. If each also loses $2,000 monthly gross receipts for two months, gross receipts at risk add $16,000. The $36,000 combined stress amount is before saved expenses, policy benefits and other uninsured costs.
Confirm the event and deductible treatment rather than assume the arithmetic describes the policy. Then test cash availability and payment timing. A shared limit may help one loss while constraining a regional event; inspect both cases.
Review valuation and program seams
Keep supported reconstruction values current. If a coinsurance condition exists, test it; a large portfolio total does not automatically satisfy every location condition. Record catastrophe sublimits, margin terms, annual aggregates and acquisition-reporting clauses.
For liability layers, match named insureds, accepted activities, dates and attachment. Keep personal and entity-owned interests explicit. Adding a building to the primary schedule should not be assumed to amend every upper contract.
Use a risk action register
| Issue | Decision or action | Owner | Evidence due | Review date |
|---|---|---|---|---|
| Unsupported building value | Obtain estimate | ________ | ________ | ________ |
| Shared-event retention | Reserve decision | ________ | ________ | ________ |
| Vendor dependency | Assign backup | ________ | ________ | ________ |
| Coverage seam | Written insurer response | ________ | ________ | ________ |
| Income gap | Funding/coverage decision | ________ | ________ | ________ |
Review on events, not only anniversaries
Revisit the register after acquisition, sale, restructuring, major work, tenant-use change or a claim. Rehearse an emergency handoff and check that backup people can access current documents securely.
Without first-party loss, engagement or conversion data, this guide does not rank which control produces the greatest financial return. Prioritize unresolved safety issues, binding conditions and material unfunded exposures using actual evidence.
