Mortgage servicers are the heart pump of the home loan world. You don't see them but you know they are there, as without their presence who would process all the loan payments?
Over the past three decades, mortgage servicers have been responsible for collecting payments and ensuring taxes are paid and core processing of the loan is handled and managed. Sometimes the mortgage servicer is your own bank, sometimes not.
This was an easy-breezy business. With good technology, a mortgage servicer could handle millions of loans daily without a stumble. Payments arrived, mortgages paid, and the circulation of dollars through the home loan process continued smoothly.
