Sean -  Thank you once again very much for your kindness, patience, and help. 

When we first came to Mortgages Unlimited, Sean Mahaffey was assigned to our refinance. We had come off of a grueling, three month negative experience with another mortgage company. Sean was quick, thorough, and very professional in assisting us with a loan. He also completed the entire process for us in less than three weeks, which was astounding to us. We would highly recommend Sean in the future and plan to use him for our next mortgage experience.

When my wife (a military vet) and I decided to get back into the home market, we could not have selected a better loan officer than Sean. I travel frequently on business, and my wife juggles work and our three children. It would have been difficult to move this loan process toward completion without Sean’s patient guidance and encouragement. In addition: the pre-qualification Sean provided us with allowed us to aggressively pursue a gorgeous home in an extremely competitive market.

Having been in the Real Estate Development business for 20 years, I have dealt with hundreds of lenders. I can say, without hesitation, that Sean is among the best on that list.

If you are considering buying a home, I can recommend Sean without reservation.
