I had an outstanding experience working with my mortgage advisor Nigel. From start to finish, he was professional, knowledgeable, and incredibly supportive throughout what can often be a stressful process. Nigel took the time to clearly explain all of my options in a way that was easy to understand, ensuring that I felt confident and well-informed at every stage. His attention to detail and responsiveness were exceptional, no question was ever too small, and was always quick to provide updates and reassurance. What really stood out was his dedication to finding the best possible deal for my circumstances. He went above and beyond to secure a competitive rate and made the entire process smooth and efficient. I would highly recommend his services to anyone looking for a reliable, trustworthy, and genuinely helpful mortgage advisor. Thank you Nigel for making what could have been a daunting experience so straightforward and stress free.

Karl has gone above and beyond helping us with our first home. He has made sure he was also available if we had any questions to ask. Me and my partner thought this would be a long a stressful process but Karl has been brilliant with us. Couldn't recommend him highly enough.

Excellent! As a repeat service user I have found the service to be excellent and effective. Friendly, accomodating, thorough and works with integrity. Peter Walker of Balgores is undoubtedly the best at his craft and his services are highly recommended.

Our advisor is Elliott Irvine. From the first conversation and throughout a bumpy ride he was supportive and encouraging. He really was genuinely thrilled when we finally got our mortgage offer. He continues to check in and make sure everything still on track, despite being busy with other clients and a baby due very soon. I don’t think we would have been successful in securing a mortgage without his help. Thank you Elliott!

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.
