They were helpful; particularly when things got difficult due to some circumstances beyond our control. Our lives were made so much easier during our journey.

Our case was somewhat complicated being one part self employed and after several failed conversations with another advice company and a recommendation from a friend we tried MAB, after just one long conversation Beth was able to obtain a DIP for us within two days and subsequently a mortgage offer for the full amount needed the following week. We were shocked (in the best way) at the level of service Beth and Jess have given us, from explaining everything in plain English to daily update calls, we have felt extremely well taken care of and our concerns heard. Nothing seemed to much for Beth and Jess as a team and their swift service was far above what we expected, I will continue to use them for all our future mortgage needs and HIGHLY recommend others to use them too.

I would highly recommend Clare for any and all mortgage queries! Clare guided us through the process from start to finish and regularly updated us throughout, making it a lot easier than we had anticipated. We'll definitely contact Clare again for any future mortgage requirements!

I would highly recommend the Mortgage Advice Bureau to everyone. My advisor was beyond helpful and explained every step of the process in great detail. He always responded almost immediately to my emails, and we had regular calls to keep me updated on the progress of my mortgage. They really did go above and beyond, and have even assisted me with different insurances and getting the best deals. Definitely plan on using again in the future, well worth the money. Made the process very stress-free.

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.
