Servicing residential mortgage loans is a relationship business. And Constellation Mortgage Solutions understands why putting the tools in your hands to manage your relationships with your borrowers and your investors are two sides of the same coin. Servicing has exacting standards, but it also has to be a people business with the flexibility to meet people where they are, whether on the phone or on the web with equal cost-effectiveness.
