Credit Union Division

When you think of a credit union, you probably think of personalized service, member benefits, and financial options that put members first. Mason-McDuffie Mortgage is a proud service affiliate of many credit unions, working to provide the same personal service credit union customers are accustomed to, and offering programs outside the scope of what a credit union is often equipped to provide.

Government lending programs, low rate jumbo options, and non-qm options are just a few of the programs Mason Mac brings to the credit union community. Members of participating credit unions receive the best of all worlds- the options they need and the service they deserve.
