    Getting a mortgage shouldn’t be complicated or hard work. Our mortgage advisors have written this guide to explain mortgage affordability. If you have a question reach out to our fee-free mortgage advisors.

    What is mortgage affordability?

    In the UK, mortgage lenders are obligated to adhere to responsible lending regulations imposed by the Financial Conduct Authority (FCA) and must assess if an individual’s financial situation can cover the loan they’re applying for. To do this, a mortgage affordability assessment is conducted – researching one’s income, debts and expenses in order to make sure payback is possible.

    Given the drastic and long-term consequences associated with failing to make mortgage payments – including losing your property, damaging credit standing, and more – it is essential that applicants can afford their mortgages. That’s why lenders conduct a meticulous affordability assessment before issuing any approvals. Furthermore, missing monthly mortgage payments carries far greater risks than not paying rent on time; so don’t be surprised if your mortgage lender denies an application for which the proposed repayment plan resembles current rent costs!

    The amount of money that can be borrowed for a mortgage is mainly determined by one’s income and expenses, however, other aspects may also have an indirect influence.

    A guide to working out roughly how much you can borrow

    Mortgage lenders can evaluate affordability in many different ways, as long as the process is fair to clients. Therefore, each lender will likely have a distinct approach. Usually borrowers are able to borrow up to 4-4.5 times their annual earnings; however, if you take your time and shop around for the best deal, it’s entirely possible that you could be approved for up to 5 times your income!

    For instance, an individual with a salary of £30,000 may be able to borrow anywhere from £120,000 all the way up to a £150,000 mortgage. Note that this amount could differ depending on your mortgage provider’s policies and specific details of your personal circumstances.

    Joint mortgage affordability

    When applying for a mortgage alongside someone else, the provider will typically take into account both applicants’ combined annual income. This allows them to borrow more since their loan amount is based on both incomes instead of just one individual’s salary. Thus, by including two sources of earnings in their affordability assessment, couples are able to maximize their borrowing potential and gain access to larger mortgages than if they had applied alone.

    For instance, two applicants earning an annual salary of £30,000 may be eligible to borrow up to a total of between £240,000 and £300,000.

    It is important to keep in mind that this is just a general guideline and the actual borrowing amount may vary based on both the lender’s policies and your individual profile.

    What affects mortgage affordability?

    Planning to buy a home? Our mortgage advisors have compiled the 10 critical factors that will affect your ability to afford a mortgage. Keep these details in mind when you are calculating how much house you can realistically purchase:

    1. Income: A higher income generally means that you will be able to borrow more, as lenders consider your ability to afford mortgage repayments.
    2. Debts: Lenders will consider any outstanding debts you have, such as credit card balances and personal loans, when determining your ability to afford a mortgage.
    3. Credit score: A higher credit score may make you a more attractive borrower to lenders, as it demonstrates your creditworthiness and ability to manage debt.
    4. Deposit: A larger down payment can reduce the size of the mortgage loan you need and make it easier to afford mortgage payments.
    5. Interest rate: A lower interest rate means lower monthly repayments, which can make it easier to afford the loan.
    6. Employment status: While a lender’s maximum income multiple stays consistent regardless of employment status, they may take greater caution with self-employed or non-salaried sources of revenue due to the potential for instability. This can affect their affordability assessment when looking at these forms of income.
    7. Loan to value: When securing a mortgage, the loan-to-value (LTV) ratio reflects how much of the property’s cost is being borrowed. Certain lenders may provide increased income multiples for mortgages with lower LTVs (such as below 85%). Not only that, but your LTV will also impact what interest rates are available to you.
    8. Property location: The location of the property you are buying can affect mortgage affordability, as home prices can vary significantly from one area to another.
    9. Property type: The type of house you purchase, whether it is a single-family home or condo, can have an impact on what kind of mortgage you are eligible for.
    10. Mortgage term: When it comes to mortgages, the duration of your term can significantly influence affordability. Opting for a longer-term often results in lower payments but with an increased total cost from interest rates over time.

    When establishing a budget, it’s essential to think about these factors and work with an experienced mortgage provider or mortgage broker to discover the right loan that fits your financial plan and objectives while also providing you access to optimal interest rates.

    FAQs

    The UK financial system relies on the mortgage affordability rule to help lenders decide how much money they can lend out. This assessment takes into account several mortgage underwriting standards including such as a borrower’s income, debts and credit score, combined with the property type and worth. With this guideline in place, everyone is treated fairly regardless of their unique situation so that potential homeowners have access to secure mortgages.

    Before you submit a mortgage application, it’s essential to consider your budget and finances. The affordability rule and underwriting standards are created with the purpose of preventing borrowers from accumulating excessive debt or struggling to make their payments. Conducting due diligence on your financial status prior to applying for a loan will help of being accepted for a mortgage approval and guarantee that you remain financially secure in the long-term.

    UK lenders determine mortgage affordability using a combination of factors, such as your income, credit score and report, and debt-to-income (DTI) ratio. To calculate the DTI ration for yourself – take your total monthly debt payments including the proposed mortgage payment – then divide it by your gross monthly income (before taxes). The percentage that you get is what we call ‘Debt to Income Ratio’, which UK lenders use to assess one’s eligibility for getting a mortgage.

    To determine your Debt-To-Income (DTI) ratio, take the total of all monthly debt payments and divide it by your gross income. For example, if you owe a total payment of £1,000 each month on top of other debts while earning £3,000 in salary per month; then 33% would be your DTI ratio. Although most lenders prefer to keep this number under 43%, some are willing to accept higher ratios depending on certain factors like credit history or type of loan sought after.

    Although there is no hard and fast affordability rule requiring lenders to offer a mortgage that amounts to five times an applicant’s annual salary, some creditors may use 4-5x income as a benchmark for the maximum loan amount they are willing to lend. Nevertheless, depending on aspects such as credit score on your credit report, debts owed, and the property purchase price; each lender can decide their own lending parameters accordingly.

    When evaluating your mortgage application, affordability is established using an interest rate that might be required to be paid in the event of a Bank of England’s interest rates increase above the lender’s standard average rate. A lower loan-to-value will increase your chances of mortgage approval and a lower mortgage rate.
