We were introduced to Jamie by a close friend, and we couldn’t be more grateful. He is truly the best and most professional broker we’ve worked with. Jamie was extremely patient and guided us through every step of the application process with clarity and care. He took the time to listen to our thoughts and address all our questions in detail.
His team, especially Tylor, was also outstanding—always responding promptly, often within the same day. We deeply appreciate all the support and are very thankful for helping us achieve a successful outcome.

We couldn't have asked for a better mortgage broker!! We're so glad they were recommended to us and we went ahead.
Andrew helped us with a total of 3 sales over the course of a year, 2 of which had unfortunately fallen through on the seller end. Andrew was always at the end of emails/phone to help us along each step and with any extra queries. We're so grateful for the expertise and great communication we recieved, thank you so much!!

Excellent service from day one, Jamie is very attentive, understands the exact needs of the client, communicates well and keeps you in a loop of any mortgage rate changes that might benefit you. I had several different mortgage advisers in the past and this is the best experience so far! Highly recommended!

We are quite happy that we followed our mutual friend's recommendation and met Jamie. Many mortgage advisors failed to secure me a mortgage for the property I was attempting to purchase, but Jamie was able to assist me in obtaining an offer within a week.
All of our inquiries were promptly and reassuringly addressed. Once again, BIG thanks to Jamie, I will be referring Alexander Southwell Mortgage Services to everyone who needs a mortgage.

Alexander Southwell Mortgage Services have been absolutely top notch. They have guided me through the entire process and taken a lot of the stress to secure my mortgage. Their communications skills ensured I was totally up to date with my options and where I was throughout the process. Additionally, the advice given throughout ensured I had everything in place to secure a property. A first class service and well recommended to anyone looking to secure a mortgage, many thanks for the excellent service.

Me and my girlfriend recently used Jamie as our mortgage advisor for the purchase of our first house and he was fantastic. As first time buyers we felt a bit out of our depth but Jamie was always on hand to answer any questions and help us anyway he could. This really helped us to understand the whole process and get to the point where we have now had an offer and our mortgage accepted.
I would recommend Alexander Southwell Mortgage Services to anyone, nothing but good things to say about them. Once again thank you Jamie, couldn't of done it without you!
