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.
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.
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
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.
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.
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.
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!
