Understanding, attentive, professional and absolutely on it. Definitely recommend. Definitely worth paying for! After trying a high street bank first and getting knocked back and demoralised, MAB helped me get an offer with a lender which supported my plans. I wish I’d gone to them first - next time I will! Particularly loved the customer focus of the team during the process. I knew exactly at what stage everything was at.

I honestly cannot recommend Joe highly enough. From start to finish, he has been absolutely fantastic. His knowledge, professionalism and attention to detail are second to none, and he makes what can often be a stressful and complicated process feel straightforward and manageable. Joe takes the time to explain everything clearly, answers any questions with patience, and genuinely goes above and beyond to make sure you feel supported and confident every step of the way. His communication is excellent, he is always approachable, and you can tell he genuinely cares about getting the best possible outcome for his clients. It is refreshing to deal with someone who is not only brilliant at what they do but also genuinely puts their customers first. Joe is a real credit to his profession, and I would not hesitate to recommend him to family, friends, or anyone looking for a mortgage advisor they can trust. If you’re looking for someone who is knowledgeable, reliable, professional and willing to go the extra mile, Joe is your man. Absolutely first-class service from beginning to end!

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.
