The amount of insurance should cover the liens on the dwelling. Also, those involved with liens should be listed as a lienholder on the policy. I am not sure how much you can push the issue without giving a notice to the borrower of the amount of insurance and deductible the bank requires.
I would look at the amount of the liens and not the appraised amount of the property in determining whether there is adequate insurance on the property.
