"We recently completed our second refinance in two years with Tom Derrick. Refinancing at these low mortgage rates is pretty much a no-brainer but the same can't be said about finding a broker.
Tom is honest and professional. We compared his numbers on both refi's and Tom had the lowest interest rates and closing costs. He makes the process easy.
We're happy to recommend him."

"When I first sent Tom Derrick an e-mail to inquire about a mortgage, I had no idea of the amazing service I was about to receive. Due to my busy work schedule, e-mail is typically the quickest and easiest way for me to communicate. Every message I sent to Tom was answered VERY quickly, usually within minutes. I was shocked when I sent him a message on a Saturday or Sunday and received a response just as quickly! This level of service can not even begin to compare to what we experienced when we were working with our bank. Tom is incredibly knowledgeable about all things related to mortgages, and was very reassuring anytime we had questions or doubts as we moved along the process. I will most definitely be recommending One Source Home Mortgage to everyone I know in the future, as we were very pleased with the quality and speed of service. Thanks again, Tom! "

"Tom Derrick was extremely helpful in the refinance process. From the first call I received from him, he gave me the information I needed to make the best decisions for my refinance. The process was simple and did not require much time or effort on my part. Tom was available when I needed to ask questions and responded quickly. The whole process was smooth. He found a Title Company that was very close to my house and scheduled the closing at the most convenient time for me. When I experienced some emotional stress with the process, he explained everything well and provided the necessary information. I would recommend him highly."
