## What Is Commercial Property Insurance?

Commercial property may fit your business if you own a building or rely on equipment and stock. Compare replacement-cost terms, deductibles and any coinsurance condition, and check lost-income protection separately. [8](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [9](https://content.naic.org/cipr-topics/business-interruptionbusinessowners-policies-bop "Business Interruption Insurance/Businessowner’s Policies (BOP)") [10](https://www.tdi.texas.gov/pubs/consumer/cb021.html "Commercial property insurance guide")

## Key Differences in Commercial Property Insurance

### Coverage and Valuation

Lockton says it can tailor a proprietary manuscript form to a client’s property needs and lists review of policy terms, deductibles, exposure values, and catastrophe modeling. MMA describes arranging coverage around an organization’s stated property risks but does not specify manuscript forms or modeling services. Complex portfolios should ask how wording and deductibles will be shaped to their locations. [4](https://global.lockton.com/us/en/products-services/property "Property Insurance") [7](https://www.marshmma.com/us/solutions/property.html "Property Insurance | MMA")

### Placement and Buyer Service

Lockton says the same property team that meets a client negotiates with underwriters directly. MMA routes property buyers to an adviser or specialist. Ask who will negotiate the wording and then review the issued policy against the negotiated terms; this is especially useful when locations share a layered program. [4](https://global.lockton.com/us/en/products-services/property "Property Insurance") [7](https://www.marshmma.com/us/solutions/property.html "Property Insurance | MMA")

## What to Confirm in Commercial Property Insurance Quotes

- Ask Lockton which manuscript clauses, retentions, and catastrophe models apply to the proposed portfolio. [4](https://global.lockton.com/us/en/products-services/property "Property Insurance")
- Ask MMA whether the quote uses standard or manuscript forms and who checks policy wording after binding. [7](https://www.marshmma.com/us/solutions/property.html "Property Insurance | MMA")
- Ask both to identify the insurer, scheduled locations, valuation basis, limits, deductibles, and exclusions. [4](https://global.lockton.com/us/en/products-services/property "Property Insurance") [7](https://www.marshmma.com/us/solutions/property.html "Property Insurance | MMA")
