    What is a Mortgage?

    Purchasing a home is a large financial move – meaning that in order to get onto the property ladder, you’ll most likely need to borrow some money. That’s where mortgages come in.

    When buying a home in the UK, you’ll usually be required to put down a cash deposit upfront – but this only covers a fraction of the property value (typically between 5 to 20%). To pay for the remainder of the cost, you’ll most likely need to successfully apply for a mortgage: a long-term, high-value property loan generally provided by a bank or building society. After the keys are in your hands, you’ll be required to pay the money you borrowed plus interest back in monthly instalments over a predetermined number of years.

    Next Steps: Mortgage in Principle

    Want evidence of how much you can afford to borrow? A mortgage in principle is the perfect step up from online calculators – offering a more accurate result, and documentation designed to stake your claim as a serious and capable buyer.

    We’ll put together a comprehensive document accurately demonstrating your borrowing potential for no additional cost – helping put you in a good position to make an offer the seller can’t refuse.

    I had so many questions and unknowns about buying my first home but none of them were too silly for Martin to answer. He helped me with finding the mortgage lender that suited me and did all the paperwork upfront, so to make everything run smoothly later on. He advised me with insurance and gave me me guidance and updates every step of the way. For me, Martin made buying my first home an exciting experience, not a stressful one and I would recommend him every time. Thank you.

    First Time Buyer Mortgage


    Martin Bright has been exceptional throughout a long and convoluted process. After three attempts at securing a house (and three mortgage searches), Martin was patient and professional, always happy to help and always finding a better deal than I thought possible. He explains things clearly and puts forward his thoughts and justifications in a very considered way. I have a 5yr fix at 0.9%. Which beggars belief really! Fantastic outcome, brilliant service and a thoroughly nice chap all round. Wouldn’t hesitate to recommend, and I already have done to a couple of friends looking to secure their own mortgages.

    First Time Buyer Mortgage


    Martin and his team were always quick to respond from mortgage application through to completion. He provided valuable advice and insight throughout, especially during the economic downturn and rapid rises with interest rates, and secured us a great deal with a lightning fast turnaround. Also, Adelle made obtaining Life and Financial Protection insurance super easy – allowing us time to look through the deals she prepared and was always willing to explain complex or unfamiliar terms to us. When we end up moving house in the future – I’m sure I’ll be giving Fees Free Mortgages a call.

    Mortgage calculators are created to be as accurate as possible – but are only as accurate as the information they receive. Whilst they can be used to give a rough guideline and help in initial calculations and searches, mortgage calculators can’t take each and every one of your outgoings into consideration. In addition, a mortgage affordability calculator may not factor in costs such as stamp duty and estate agents’ costs. 

    If you’re ready to take steps beyond a general insight into your borrowing situation, the best next step to take is to visit a reputable mortgage broker for mortgage advice or to attain a mortgage in principle to assist in your house search. They’ll be able to factor in your unique financial circumstances and situation to create a more accurate guideline as to how much you’ll be able to borrow and repay.

    In the UK at this time, a mortgage offering with a multiple of five or above is possible for those who fit the necessary lending criteria and affordability checks but is relatively uncommon. Instead, the vast majority of mortgage lenders offer lower multiples between 3-4.5. The exact multiple you’ll be offered is determined by a number of factors including your income, LTV, credit history, age, and career type. 

    The mortgage borrowing calculator above will be able to offer you a general level of insight into how much you may be able to borrow – but isn’t a guarantee. If you’d like to establish how much you’ll be able to borrow with a MIP, or begin your mortgaging journey, get in contact with Fees Free Mortgages today.

    The vast majority of UK mortgage lenders will offer income multiples of between 3 and 4.5 – though some will be willing to offer a 5 or 6 times salary for individuals meeting the correct requirements relating to income, career type, credit history, and age. It’s unlikely to find a lender offering anything above a 6 times salary mortgage. 

    The exact amount you’ll be able to borrow in relation to your salary will vary from lender to lender – and so, can’t be guaranteed online. However, the mortgage borrowing calculator above will be able to offer you a general level of insight into how much you may be able to borrow. If you’d like to establish how much you’ll be able to borrow with a MIP, or begin your mortgaging journey, get in contact with Fees Free Mortgages today. 

    Required levels of debt to income aren’t set, and can vary according to your selected lender and their individual requirements. With this being said, the vast majority of lenders have an absolute maximum debt to income ratio of 50% – and may recommend that you take action to decrease prior to applying for a mortgage around this figure. More favourable rates will typically be offered to those with a ratio of around 20 to 30% – as they present a lower risk. 

    How much of your salary you should be spending on your mortgage ultimately depends on your income, budget, debts, and other expenses. Whilst a common figure discussed by money experts is that your ‘monthly mortgage and related housing expenses should be no more than 28% of your gross monthly income.’

    If you’re unsure of how much you’ll be able to afford, our experts highly recommend arranging a fee-free, no-obligation mortgage advice appointment or consultation, during which one of our experienced mortgage brokers will work through your finances, and make accordant recommendations for your next steps. If you’re not quite ready to speak to someone yet, the above mortgage borrowing calculator will be able to provide a general guideline as to how much you’ll be able to afford to borrow.
