Jade, was brilliant from the start of the process to completion. Always at the end of the phone or email and happy to help me with everything and always willing to answer my questions and believe me I had a lot of questions! She made the whole process of getting a mortgage seamless and stress free. I will definitely be recommending Jade and the Mortgage advice Bureau to anyone I know who is getting a mortgage. Jade found me a fantastic deal on my mortgage and Life insurance. Jade also helped getting me home and contents insurance by passing me on to her colleague Dominic, Dominic was brilliant as well, and found me a brilliant deal with LV he explained the process and what I needed to get covered and helped me make the best possible choice for the best possible price. Jade and Dominic were great and I would defiantly recommend anyone to go to the mortgage advice bureau when buying a property. Thanks both

As first time buyers we found them very helpful in guiding us on what to do , Neil Hutchinson was a huge help. I felt like I could contact him to help with anything I wasn’t sure on and he would reply quickly and give me the help I needed. Nothing was too much to ask. Highly recommend and definitely made the process a lot smoother for us.

Working with Sean Mungavin on my mortgage was honestly one of the best decisions I made throughout the whole process. From the very beginning, he was patient, clear, and genuinely invested in making sure everything went smoothly for me. He checked in regularly without me ever having to chase him, kept me informed at every stage, and made sure I understood exactly what was happening and why. His guidance took a lot of stress off my shoulders. Toward the end of the process, Katrina Gould stepped in, and she was just as professional and supportive. She picked things up seamlessly and helped make sure the final steps were handled quickly and accurately. Their teamwork made the entire experience feel organised, personal, and much easier than I expected. I’m genuinely grateful for all the help from both Sean and Katrina and would highly recommend them to anyone looking for a reliable and caring mortgage team.

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.
