What is an Offset Mortgage?

An offset mortgage is a mortgage held in the same bank as the borrower's deposit accounts, savings accounts or other accounts. The mortgage payments are calculated based on the borrower's combined balance. Offset mortgages are not allowed in the United States.

How Does an Offset Mortgage Work?

For example, let's say John Doe has a checking account, a savings account and a mortgage from Bank XYZ. Like all mortgages, the bank calculates the interest on the mortgage principal every month. However, in an offset mortgage, the bank reduces the amount of the principal by the amount of the deposit balances and then calculates the interest on the net amount.

For example, if the borrower had $10,000 in her checking and savings accounts with Bank XYZ and a $200,000 mortgage balance, the bank would calculate the interest on a $190,000 rather than $200,000.
