1. Mortgage of a property is not registered in any registration office to enable you to verify,
2. Moreover, a mortgaged oroperty can not be dealt with by the mortgagor without the written consent of the mortgagee,
3. The outstanding loan amount can be found from the latest statement of accounts issued by the Bank and in the instant case, the value of the property does not cover the aggregate of outstanding loan amount of the Bank and the loan outstanding lying with you,
4. So, the proposal of double mortgage is not feasable,
5. You can buy the other property to realise your debt,
6. One note of caution, do not claim anywhere interest on the loan provided if you do not have license for money lending against interest.
