Oh it was a wonderful experience, when we got in contact with them was when all hope was lost because of our visa status but Sean came into our life and everything became possible starting from growing our credit score to achieving our dream home, he was like a God sent. We will for ever be grateful for the way he takes time to explain and advise us on the best decisions, the way he was always available, the quick respond to mails and the way he makes everything look easy with so much encouragement. They are actually the best in this.

I approached Vimal Patel regarding my residential mortgage and BTL. Right from the start, Vimal explained the process, what my options were, did the the calculations based on my requirements and got the process going. He is a true professsional, keeps you updated throughout the process. I would definatly recommend Vimal for all your mortgage requirements.

Mark de Mel has been brilliant. He managed to get me two mortgage offers very quickly, and was able to talk me through the process clearly, and was available any time. He answered all my questions quickly and made the whole process seem less stressful for me as a first time buyer.

Marcus Rowland was excellent. More than happy to explain any aspects I didn't understand, very friendly and most importantly got me a great deal on my mortgage.

I went into this process knowing absolutely nothing about mortgages and feeling pretty overwhelmed. From the very beginning, Chloe made me feel completely at ease. She took the time to explain everything clearly, answered every question (even the ones I didn’t know I should be asking), and guided me step by step through the whole process. Her communication was excellent throughout, and I always felt supported and kept in the loop. What could have been incredibly stressful ended up feeling manageable and reassuring. Even after my mortgage was accepted, Chloe continues to offer support and guidance, which really goes above and beyond. I honestly couldn’t have asked for a better experience and would highly recommend her, especially to first-time buyers

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.
