“Jim I just wanted to, again, say a heartfelt Thank You for everything you (And everyone else in your office) did for me in pushing the financing through to get our deal done. I truly appreciate and understand all the hard work and effort it took for you guys to deal with the obstacles that presented themselves throughout the whole process. We absolutely LOVE our new house, and I know it would not have happened this soon (Or quite possibly at all) without your help and guidance throughout the whole process. I will make it my personal mission to tell everyone I know about your office and what you guys did for me. Again- Thank You.”




“Maritime Mortgage came through for me when all other options came up short. I had chosen a home and was in the middle of the purchase process when the previous broker called in the 11th hour to say that they had overlooked a detail that ground the process to a complete halt. As you can imagine, this threw a wrench into the works in every way, and I was forced to scramble around for a workable option or lose the house. A trusted friend recommended Jim Brennan and Maritime Mortgage, and Jim immediately went to work securing the financing, reassuring the sellers and their realtor that they could rely on the deal going through, and working with me in the most professional, respectful, reassuring way possible. His office staff was friendly, thorough and professional as well. I have recommended Maritime very highly to everyone I know, and will never do business with anyone else again! Thanks Jim, Jazmine and all of your team for turning my dream into reality, and making a worst-case scenario turn out beautifully!”
