This has been a wonderful experience for us. Paul De Stefano is highly intelligent, professional, and innovative in his approach. As first-time buyers, he helped us find the lender that best suited our situation and guided us through every step of the mortgage process. He balances professionalism with genuine empathy, which made the entire experience much smoother for us. We truly appreciated his guidance and would highly recommend him.

Beth and Jess were fab! We initally had a mortgage in principle that expired when we couldn’t find a house we loved/offer accepted. When we found a house we loved and Beth worked hard to get us a MIP the same day so we could put an offer in. We were updated every step of the way and I felt able to ask any questions, replies were prompt and informative. I was given a rough timeline but whole process was so quick plus affordable! Beth gave informed recommendations but also listened to my opinions and concerns and found a mortgage which worked for this! Jess answered any questions I had and also kept me in the loop with all advances in my application. I was recommended to speak to Kieran who supports with life and critical care coverage. He has been thorough and is working towards cover for my partner and I. I can’t thank the girls and Kieran enough for making this process a completely stress free experience!

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.
