Josh was my main contact at MAB and he has been incredibly helpful. Josh communicated clearly all the information throughout the process. My questions were answered quickly and all information was passed on straight away. Joanne the case mananger was equally as good with communicating and passing on information. I have had no issues with MAB, even with the mortgage application being sent over Christmas. I would highly recommend MAB based on my experience with Josh Hayseldon and Joanne McGregor.

It’s been a long long time since I’ve had to arrange a new mortgage, I wasn’t even sure how the process progressed these days, Rachael had my back all the way, dealing with confusing paperwork solicitors, banks etc, making the whole situation a lot calmer than if I’d had to muddle through it on my own, Lucy kept me up to date with emails, they are the perfect team going the extra mile to ensure a stress free process, so if you’re worrying about applying for a mortgage, contact this dream team & rest assured you’ll be in good hands, don’t just take my word for it, read the reviews, I can’t thank them enough Five Star⭐ all the way.

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.
