2. Any act of the mortgagor, prior to the loss, which would otherwise avoid the insurance,
will have the same effects, although the property is in the hands of the mortgagee.
3. Any act, which under the contract of insurance is to be performed by the mortgagor, may be performed by the mortgagee with the same effect as if it has been performed by the mortgagor.
4. Upon the occurrence of the loss, the mortgagee is entitled to recover to the extent of his credit and the balance, if any, is payable to the mortgagor since such policy is for the benefit of both the mortgagor and mortgagee.
5. Upon recovery of the mortgagee to the extent of his credit from the insurer, the mortgagor
is released from his indebtedness.
