Is it worthwhile to pay a higher premium but less out of pocket when a hurricane hits? That depends. Let's say a building is worth $10 million. The deductible will be $200,000 less with the lower percentage figure.

What would it cost to upgrade the building after a storm rips through it? Based on that estimate, amortize the difference in the premiums over the number of years without a major storm. If an owner had the lower deductible just before the major storms of 2004 and 2005, he or she would come out ahead.

We haven't had a major storm in 10 years, so many owners saved money with the higher deductible. But who knows when our good fortune will end. Second, if the property hasn't had an appraisal in a number of years, order one and use that figure to update the policy. Prices are going up, and the estimated value on the policy may be too low.
