Both people I dealt with could not have been more helpful. I've never had a mortgage before and no matter what questions I asked I was answered, reassured and felt looked after at every step. The MAB came recommended to me by a friend who used the company recently and now I too would recommend them. I can't thank L and N enough to the point where, all being well, they are invited to the housewarming. Thank you thank you thank you....

Our Mortgage Advisor Mark Bell Langford has been amazing from the start. Explains everything so it is easy to understand. Very responsive. Very helpful. Very friendly and easy to talk to. We could not have got through our purchase of our house without him. I have contacted him almost everyday throughout and no question is ever to silly. Finding a suitable mortgage. Suitable insurances. Not trying to make money but actually doing what is best for you. Cannot recommend him enough.

The service we have received over the last 6 months has been excellent. We are first time buyers and didn’t know much about the whole process of buying a house but sarah has been very helpful and knowledgeable with it all.

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.
