The agent whom I have been dealing with (Paul) was very professional, understanding and empathetic to the woes of a first time buyer. He is very patient and open to answer questions and has a very quick response time.

From start to finish, Ian, Katie, Beth and anybody else I have dealt with in relation to my new mortgage have been absolutely fantastic! I have been made to feel totally at ease throughout, all of my worries and issues that led to me seeking advice in the first place have been handled with the utmost sensitivity and the solutions proposed have been tailored to meet our needs wholly. I used MAB when I bought my first house and I do not regret using them again, the service has been exceptional. I will be back if needed in the future. Thank you from the bottom of my heart for helping in the way that you have all helped me. I, with your help and guidance will be able to have a hugely better quality of life moving forward. Thanks, Rich Mobbs

The service we received was friendly and welcoming. This is our first time buying a property and we were made to feel at ease and supported with all the information explained to us. We were shown all our options and felt very much in control. The whole process has been speedy and very organised. We cannot fault the service we have received and we would definitely recommend you to friends and family.

Can’t recommend this company enough. Frances helps us every step of the way and is always there for support and answer any questions we have. We’ve used this company a few times now and have even encouraged family and friends to go with them. They also have had a great experience.

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.
