Patient, friendly and swift to respond. I keep coming back to MAB. Amy was a great hope throught the many ups and downs of the process and several false starts. She provided insight and advice throughout and had the ability to be someone we could bounce ideas off as well as giving solid professional expertises.

I honestly can’t recommend Martin Waite at Mortgage Advice Bureau highly enough. I’ve been using Martin for many years now, and this must be at least my 10th mortgage or remortgage with him — which really says everything about the level of service and trust I have in him. Martin is exceptional at what he does. He’s extremely knowledgeable, professional and reliable, but what really stands out is how approachable and flexible he is. Whenever I’ve needed to make changes or something unexpected has come up, Martin has always been incredibly responsive and has gone above and beyond to find a solution. The first time I used Martin, I was told by other mortgage advisers that what I wanted to achieve simply wasn’t possible within the timeframe. Martin didn’t see it that way. He took it on with confidence, knew exactly what needed to be done and managed to get it completed incredibly quickly. Since then, I’ve had absolutely no reason to look anywhere else. Over the years, Martin has consistently delivered, made what can often be a stressful process feel straightforward, and always given me complete confidence that I’m in safe hands. After 10+ mortgages and remortgages, I wouldn’t use anyone else. Martin is an absolute credit to Mortgage Advice Bureau and I would recommend him without hesitation — 100% outstanding service.

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.
