Welcome, and thank you for visiting JM Loans, your direct access to John Meussner, one of the nations leading mortgage bankers!

     Over the years we've learned a few things about what's needed in a perfect mortgage loan - low rates & costs, an efficient process, and products diverse enough to match the diversity of situations out there.  The perfect loan.  At Mason-McDuffie Mortgage that's what we strive to provide each and every client. Whatever type of residential mortgage product you're seeking, we have an option for you.  We have the knowledge to help the most experienced real estate investors, and the experience to help first time home buyers navigate the path to home ownership.  We help home buyers find the best purchase loans, homeowners save money and reach their financial goals through refinance programs, and serve the needs of real estate agents, financial advisors, CPAs, builders, and attorneys in helping their clients achieve the dream of home ownership, and move forward on the road to wealth and financial success.

     My goal is to help my clients find the right loan product at the best price.  We're known for great rates and low prices, but when the loan process is complete, many clients say their favorite part of working with John Meussner & the Mason-McDuffie team is the level of service provided along the way.

     We are experts in many types of mortgage products, and all of them come with low rates.  Here are a few of our specialties:
     Mason-McDuffie is licensed to lend in many states across the country.  John is personally licensed in CA, DE, FL, NJ, and PA (with more states on the way).  Need a mortgage somewhere we're unlicensed?  We have a great network of trusted professionals around the country, so if you need a great referral, ask here.
