I am a first time home buyer and Justin made each step stress-free. Justin is easy to speak with and very knowledgeable. I felt comfortable to ask questions and he was available to provide me with answer in a timely manner. Thank you for everything!

Great job from pre-approval to close. Made the process smooth and quickly responded to any questions or concerns that came up.



Justin combines his professional knowledge, customer service and personal skills to be a great mortgage broker. He gets to know his clients and the clients’ goals; then he applies his full talents and coordinates with the lending team to produce optimal results in the shortest period possible. It’s a pleasure working with him.

We had a great experience working with Diversified Mortgage Group. They were honest and straightforward with setting expectations and communicated well each step of the way. They were quick to respond and helped us make the best decisions for our specific situation. They helped make a challenging situation much easier to navigate. Thankful for all their help!

Diversified Mortgage - specifically Justin Castro - has been FANTASTIC to partner with throughout my home buying process. As a first time home buyer, I had absolutely no idea what to expect. From first getting approved, having an offer accepted, to signing the documents, Justin and his team were there every step of the way. He made sure to connect often and walk me through the happenings of each event, so I really understood what was going on. The level of communication, patience, and attention to detail you get with Justin is unparalleled.

Justin and Debi did a great job on our cash our refinance for our home remodel. We've worked with Debi for years and wouldn't go anywhere else. This was our first time working with Justin and the experience was flawless! Justin is professional, answered all of our questions in a timely manner, and was always available when we needed anything. Thanks again!



This was my first home purchase, and from start to finish Justin was amazing. Even though it can usually be a stressful situation I never felt like that. Just in had answers to all my questions and was super easy to work with. I will be suggesting Justin to anyone purchasing a home.
