Emma and Kayleigh have been extremely helpful during my mortgage process. They were very quick and organised, keeping me updated throughout the whole mortgage application and made sure I supplied the correct information and documents to make sure my application was successful.

I am about to purchase my first property and Mark's assistance has been great 👍 I put in a couple of offers on different properties and my offers were rejected, I then increased my budget and then reduced it again, it's been tough but Mark has been so readily available and at hand to send me new quotes and ensure I am getting the best deal available. I have felt very confident and would not hesitate to recommend.

Ian and katie turner - both are wonderful people and great at what they do. From starting this process with us back in may they have been patient and understanding with mine and my partner’s circumstances and helped us through any bumps in the road. As first time buyers they have made this process smooth and clear on how we can work together to move forward through each step. Both are very keen to keep you in the loop which keeps the stress of. (super helpful) I’d highly recommend them to anyone as we have full faith in their knowledge. Massive Thanks to you both Hannah & Billy x

Joe has been really responsive to all the questions we've had about the mortgage and has been really transparent about the same. Darryl-Jane who was helping us with the further process has been really proactive in seeking all the information requested by the lender and ensured for a smooth process.

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.
