What are mortgage services used for?

All banks employ some form of mortgage services to keep tract of the "bank-homeowner" contract. The homeowner is obligated to pay back the principal mortgage loan of the house, plus interest, until it is paid off. If a homeowner finds it difficult to make a mortgage payment, the bank can offer a special forbearance service, which is a temporary reprieve from having to make a mortgage payment or two on time. However, those payments become due when the forbearance is over. Also, for people with good credit and substantial equity built up, the bank allows them to take out a HELOC loan.
