Write to the Trustee and ask for an estimated pay-off. Understand, however, that any pay-off figure you receive from the Trustee is an estimate. It will not include any filed claims that the Trustee is not aware of, nor will it include interest that will accrue in the future on any secured claims. If your plan pays less than 100% to your unsecured creditors, you may be required to increase that percentage to 100% if you are seeking to pay off your plan early. Contact your attorney for more details.
