We were referred to MAB as part of a new home purchase and the service we’ve received has been of a very high standard. Melanie was really knowledgeable, and gave us a recommendation based on our individual circumstances - we could not have asked for better help. Her colleagues Darryl and Laura were great at keeping us up-to-date and getting the offer out to us in short order. Given the service was free (they’re paid by the lender) we are very grateful to MAB.

This was our first purchase and we had Paul and he has been 10/10 all the way through. We’ve had many laughs which put our nerves at ease but he is also informative and professional. I would recommend to anyone. Luke & Holly

we were pleasantly surprised about the process as this was as buying our first home. The new build developer recommended the bureau and we were placed with Paul. He was friendly but professional, knowledgeable and approachable, fitting phone calls of meetings around our schedule and never being too pushy. We thought that this would be a long painful process and it was made very easy very simple and we were kept in the loop all the way through with regular updates time scales and prices so it meant that we didn’t have to think about a thing it was all dealt with and done within two weeks.

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.
