We should be able to reconcile these accounts like bank and credit cards. If I have the same mortgage for 20 years - I now have 12 months * 20 years worth of monthly activity.
Does the balance shown in the account agree with the lender's statement?
If so, simply select the 1st transaction in the account, hold down Shift and click the transaction that agrees with the statement (near the last, if not actual last), then RIGHT-click in the CLR column ans select "Reconciled".
Works in both liability and asset accounts.
BUT, take a backup first … just in case.
