As a first time buyer I thought I had done all the research in the world about how to do things but I quickly learnt I didn’t know much at all. As soon as I contacted Joel and went through my options he made it very clear what was possible and what was the best way to go about everything. I can’t express enough how much of a help the team was everytime I called them I got put straight through if he wasn’t available they left a message and he called be right back. The communication is top notch I couldn’t fault it in the slightest. Again thank you again for all the help. I’ll definitely be using mortage advise bureau again

My experience with Neil Robert has been amazing. He is an absolute gentleman who helped me with everything throughout the process, and nothing was ever a problem. His professionalism and support made the whole experience smooth and stress-free. He is a real credit to the company.

I was a phone in and the consultant Joel was extremely friendly and very helpful. He understood what I required and didn’t push me into anything I didn’t need, while still giving me the best deal. Over all Joel was an absolute legend.

I have been working with Paula Griffiths and Andrew Guest and they have been great. Paula did all the information gathering and application which was done swiftly and managed to avoid the next interest rate increase. She explained everything thoroughly and was honest throughout e.g advising you may get lower interest by paying a 1000 product fee upfront but you probably wont get that 1000 back on your size loan so not worth it which is great. She has communicated throughout and santander came back with an offer within 2 days so I imagine the pack Paula send over was very well done. Andrew then contacted me yesterday about the offer being given and I asked if I could call with questions about the solicitors questionnaire, he called me on the same day and helped me through it, explaining any questions I didnt understand. I definitely recommend both of these people as the communication is great and they make sure I understand everything

Clear guidance on all the options. No pushy sales, the decision is always yours to make. Once you have made your decision the process is very quick. Paul Smith has simply made mortgages a none issue for me over the last ten years.

Beth was amazing from start to finish, advised me at every step of the process and made what is a very stressful part of buying a home seamless. Will be recommending MAB to any friends and family looking to buy a home or remortgage.

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.
