When your past borrowers purchase other homes or refinance their existing homes, you should create a new borrower record. Since each borrower record represents a loan transaction, you should add the borrower again and record the details of the new loan. You should then go to the duplicate borrower record and set the Mail Status to Don’t Send Letters.

 If you modify the existing record for the new transaction, you will lose information about all past loans with customers. This affects loan reports.
