What happens if the insured fails to hold more than 80% of the property value?

When the insured does not maintain coverage for at least 80% of the property's value, it results in a situation known as a "coinsurance penalty." This means that if a loss occurs and a claim is filed, the insurance company may reduce the payout based on a penalty related to the insured value. Specifically, the payout can be decreased proportionally based on the amount of coverage the insured held compared to the required amount. This concept is rooted in insurance policy structures that aim to ensure policyholders maintain adequate coverage relative to their property's value to avoid underinsurance. Therefore, if coverage is below this threshold, the insurance company will not pay the full amount of the claim, effectively imposing a financial responsibility on the insured for not having sufficient coverage.

In contrast, the other options suggest more extreme outcomes such as immediate termination of the policy or no repercussions at all, which do not accurately represent the typical consequences of underinsurance in standard property insurance practices.
