If you are in arrears some of the following charges might be applicable to you.
NSF Fees – for each missed payment there are non-sufficient funds charges by your bank and mortgage lender. This can add up quickly with each mortgage payment you miss.
Interest Fees – interest continues to accrue with each missed payment on the outstanding amounts.
Legal Fees – if your mortgage has been past due for a long period of time, your mortgage lender may start legal action. This means legal costs will be tacked on to the balance owed along with all other fees.
