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.
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!!
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!
