Insurable Value
Given these practical considerations, the Agencies are adopting question and answer 9 with a revision to provide that, in calculating the required amount of insurance, the lender and borrower (either by themselves or in consultation with the flood insurance provider or other appropriate professional) may choose from a variety of approaches or methods to establish a reasonable valuation. They may use an appraisal based on a cost-value (not market-value) approach, a construction-cost calculation, the insurable value used in a hazard insurance policy (recognizing that the insurable value for flood insurance purposes may differ from the coverage provided by the hazard insurance and that adjustments may be necessary; for example, most hazard policies do not cover foundations), or any other reasonable approach, so long as it can be supported. It is important for lenders to recognize that, when calculating the minimum amount of insurance that is required to be purchased, the insurable value is only relevant to the extent that it is lower than either the outstanding principal balance of the loan or the maximum amount of insurance available under the NFIP.

Because an NFIP policy will not pay a claim in excess of a property’s insurable value, it is important that this value be determined correctly. A miscalculation of the property’s insurance value could cause the lender to inadvertently require the borrower to purchase too much or too little flood insurance coverage, resulting in a violation. For example, if the value of the land is not excluded when determining the insurable value of a home or building, the borrower will purchase coverage exceeding the amount the NFIP will pay for a covered loss.33
To provide greater clarity about insurable value, the agencies issued Interagency Flood Q&A 9 in October 2011. Interagency Flood Q&A 9 explains that while equating the insurable value to replacement cost value (RCV) is appropriate in some cases, RCV should not be used as a proxy for insurable value for properties whose insurance loss payout would ordinarily be based on actual cash value:
Strictly linking insurable value to RCV is not practical in all cases. In cases involving certain residential or condominium properties, insurance policies should be written to, and the insurance loss payout usually would be the equivalent of, RCV. However, in cases involving nonresidential properties, and even some residential properties, where the insurance loss payout would normally be based on actual cash value, which is RCV less physical depreciation, insurance policies written at RCV may require an insured to pay for coverage that exceeds the amount the NFIP would pay in the event of a loss. Therefore, it is reasonable for lenders, in determining the amount of flood insurance required, to consider the extent of recovery allowed under the NFIP policy for the type of property being insured.34
The guidance further states that when this occurs, lenders may choose from any reasonable approach to calculate insurable value as long as it can be supported. The guidance provides examples of permissible methods, including appraisal based on a cost-value (not market-value) approach, a construction-cost calculation, and the insurable value used in a hazard insurance policy with appropriate adjustments.35
