Owner Financed properties - Minimum insurance coverage

[Marie Shaug]

I have sold 3 properties to someone and have just learned that the insurance they have on those properties is the absolute minimum, fire and lightning only. It does not include wind, hail, hurricane, tornado, vandalism, etc.    In a case like this, can I legally require the buyer to up the coverage of these properties, since I potentially would suffer the loss if the property was destroyed or damaged?  Thanks for any input.
