Your Journey Home Starts Here

Mason-McDuffie Mortgage - Rooftops Favicon

Welcome to, where our goal is always to help you reach your goals.

Whether you're a first time buyer, seasoned investor, or home owner wanting to put home equity to work, we've got the mortgage products to help.  We focus on a fast, streamlined process, competitive costs & rates, and product offerings that match the diversity of our customers.


Our team also serves many industry professionals, providing a source to assist the clients of real estate agents, attorneys, financial advisers, and others who recognize the huge role mortgage & home play as an asset, a debt, an investment, and a place to live life.  Over the years, we've worked to utilize the latest technology (without demanding our customers are too tech-savvy) to create an industry leading process.  Fast.  Easy.  And dare we say, occasionally, fun.  That's why we've built a following of repeat customers.  While we're focused on the loan you need today, we also strive to ensure you're in the best situation for tomorrow.


Our company, MasonMac, is licensed to lend in many states across the country. John is personally licensed in AZ, CA, CO, DE, DC, FL, GA, IN, MD, MN, MT, NC, NJ, NV, OK, OR, PA, SC, SD, TN, TX, UT, VA, and WI. To help those in states where we're not licensed, we've also created a well vetted network of professionals around the country, so if you need a great referral, ask here.


We welcome the opportunity to help with any mortgage needs you have, and invite you to reach out any time - you can call John at 949-247-7530.  And while you may get voicemail, when you're working with our team, you'll never be expected to talk to a robot.  We're people here to serve people, and can't wait to talk with you.
