In - - we took out a 15 year mortgage of $ --4.875 % annual interest rate. The lender bank was - sold and the current lender is PNC Mortgage. 180 monthly payments were $2900.00 plus current local realty taxes of $670.00 = $ -/month. We have a current principal balance of approximately $120000.00. BUT we missed - payment in - -. Ever since, PNC has assessed us a late charge of $140.00 each month. PNC is demanding a total of $8100.00 ( $7300.00 for - monthly payments and $660.00 late charges. [ I know this does not add up ] ) before we can put our mortgage on an even keel. PNC refuses to consider extending the term by - month to - -, which makes is impossible for us to catch up. Is the CFPB able to help us?
