It was a long process buying my house but Andrew was there for every step of the way. He answered all my questions, discussed any issues that I had and provided great guidance throughout for my mortgage deal. Couldn't rate them highly enough!

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 had the pleasure of working with Alexander Southwell Mortgage Services as our mortgage advisers and we couldn’t be more satisfied with the experience. From the beginning, Latoya and Jamie demonstrated a high level of professionalism, knowledge, and dedication.
Throughout the entire mortgage process, Latoya was clear and communicative, always taking the time to explain our options and answer our questions. She made what can often be a stressful and confusing process feel straightforward and manageable.
They always had our best interests in mind. The process was efficient, transparent, and ultimately led to a successful outcome.
We would highly recommend Alexander Southwell Mortgage Services - Southampton to anyone in need of mortgage advice. They are a true professional and a trusted partner in navigating one of life’s biggest financial decisions.

So this was myself and my partners first time buying and honestly we were totally clueless on the process! A mutual friend/client of Jamie & Latoya recommended them to us and I’m so incredibly glad he did.

From the start, Jamie quickly put us in touch with Latoya and we got things underway instantly. Throughout the whole process, communication was utterly seamless and there was no such thing as a silly question (trust me, I asked a few!). Latoya was transparent about every step, advising us down the best possible avenue - ensuring we got the best outcome for us. Keeping us up to date about each part of the application process, there was absolutely no need to chase - as soon as she had anything for us - we were straight in the loop.

Honestly, she made what was quite a daunting idea to us - so reassuring and easy.

Thank you so much to Latoya and Jamie for your incredible service and support! We’ll be singing your praises and sending anybody we can, your way 😊

All the best to you both,

Joe & Naomi

Latoya was professional, friendly and communicative when helping me get my mortgage as a first time buyer. Full explanations of everything she needed were given and no question were unanswered. Thank you!

Jamie and the team at AS Mortgages have been superb at helping sort out a new mortgage for a house move. From searching for the best product, to finding the best lender, they have been amazing.
This isn’t the fist time we have used the services at AS mortgages. Previously have helped us with two other mortgages on previous properties and securing a new fixed rate. Every time the service is quick, easy and painless. We have recommended AS Mortgages to family, friends and colleagues - everyone who has used them has had the same great experience as us. Can’t recommend highly enough.

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!

Latoya was really great and helped us secure our first mortgage. She was always on hand to answer my numerous 'first-timer' questions. We had very unique circumstances, but she made everything so easy. Highly recommend.

Highly recommended

Previously, we had been given unaffordably optimistic deals, or bluntly told "No" without a reason, by several mortgage advisors.

Fortunately we were put into contact with Alexander Southwell, where Jamie was able to clearly explain the process of getting a mortgage, all the steps we would have to go through, and then secured for us an affordable mortgage. He kept in regular contact about hwo the deal was progressing, and was also flexible in making and taking calls from us. Thank you, Jamie.

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.

We had a great experience with Andrew. I'm very grateful for the quick and efficient process. Andrew has given us all the information & advice we needed and helped us find the right lender for our circumstances. We will definitely be recommending Alexander Southwell Mortgage Services to our friends. We look forward to using the same service for later when we remortgage! Many thanks.

Excellent service throughout the process of mortgage application from Jamie, we use Southwell Mortgage over 5 year now on more than one property. also pleased recommend him to our friends. He is very hands-on and very good at explaining the process and making sure he follows correct procedures to work within ethical guidelines, yet makes customers happy by educating whats right for us when making a mortgage by reassuring them the whole time. He is very friendly and proficient in checking and requesting the right documents, also more than happy to answer any questions that I had and was quick to respond to any enquiries that I sent to him. Cannot recommend enough this highly professional, positive and motivated person!

I was recommended Jamie at Alexander Southwell by a Hampshire based housing developer. Both myself and my partner are self employed so finding a mortgage to suit has always been difficult in the past. Jamie however managed to get us a mortgage offer within a week with no issues at all! Amazing service and highly recommend.

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!
