Answer:
The mortgage/DOT only secures the outstanding balance of the loan up to the maximum amount stated on the mortgage/DOT. If the mortgage/DOT secures up to a maximum of $200,000, you could not sue for the $200,000 if the balance is only $100,000, so your security interest is only $100,000. Any new money advanced above the $100,000 would be an increase in your security interest and subject to the ROR.
