I cannot rate Lucy highly enough ! This was our first buy to let mortgage and we were anxious about what our options were and what we would need to do/provide. Lucy explained all our options to us in a clear and considered way and was always on hand to answer any questions. Lucy kept us updated at every stage and was in touch as soon as there was anything to report. She went above and beyond to make sure she found us the best product and was extremely patient and professional throughout.

I would highly recommend Yogesh Maisuria for his excellent assistance and support throughout my mortgage process. He was extremely helpful from start to finish and was always on hand to answer the many questions I had, responding quickly and clearly every time. What I particularly appreciated was how well Yogesh kept me updated throughout the whole process. I always knew what was happening and what the next steps were, which made what could have been a stressful process much easier. Yogesh was professional, approachable and incredibly helpful throughout, and I wouldn’t hesitate to use his services again. I’d be very happy to recommend Yogesh’s services to anyone looking for a knowledgeable and reliable mortgage advisor.

The service was excellent. Our agent listened to our relatively complex situation and despite that, she was still able to secure us a great mortgage offer from a high street bank! Definitely worth it for anyone who wants to buy a house but has no clue on how to secure a mortgage.

Questions about our mortgage calculators

What are mortgage calculators?

Our mortgage calculators are digital tools designed to help you estimate your potential borrowing power and mortgage repayments. They’re a handy way of helping you understand your financial commitments before speaking to one of our expert advisers.

Is using our mortgage calculators right for you?

Our free digital tools are designed for anyone looking to purchase a home. This means if you’re a first time buyer, someone looking to move home, or you’re on the hunt for a remortgaging deal, our calculators are for you.

What information do I need to use a calculator and how does it work?

We have several handy calculators for borrowing, mortgage repayments, remortgaging, and Stamp Duty.

These all require two to three pieces of key information, which the calculators then use to provide you with an indication on what the potential costs could be.

Please remember that lenders also take a close look at other factors. These will include your credit score, financial history, and personal expenditures. All of this information will affect the actual calculation of your mortgage and monthly repayments.

Our mortgage calculators empower you to be as informed as possible when it comes to finding the right mortgage deal for you and your circumstances.

What are the next steps after using the calculators?

If you’d like to discuss moving forward with your homebuying journey, our expert advisers are here to help provide guidance and answer any questions you may have. You can also download the My MAB app, which allows you to save, plan, and track every stage of buying your new home and beyond.
