    Frequently Asked Questions

    Common questions about mortgage affordability and borrowing

    1

    How much can I borrow for a mortgage?

    Most UK lenders use an income multiple of 4-4.5 times your annual salary for standard applications. Some lenders offer up to 5-5.5x for higher earners or professionals. Your maximum borrowing also depends on your outgoings, credit score, deposit size, and the property's value.

    2

    What is a mortgage affordability assessment?

    A mortgage affordability assessment is how lenders determine if you can afford the mortgage repayments. They look at your income, regular outgoings, existing debts, and apply a 'stress test' to check you could still afford payments if interest rates rise. This calculator simulates these assessments across multiple lenders.

    3

    Why do different lenders offer different maximum loans?

    Each lender has their own affordability model, stress test rates, and income multiples. High street banks typically use more conservative calculations, while specialist lenders may consider more of your income (like bonuses or overtime) or offer higher income multiples for certain professions.

    4

    How does my deposit affect how much I can borrow?

    A larger deposit reduces your Loan-to-Value (LTV) ratio, which can give you access to better rates and higher income multiples. Some lenders offer enhanced borrowing at lower LTVs. For example, with a 40% deposit (60% LTV), you may qualify for higher income multiples than with a 5% deposit (95% LTV).

    5

    Do credit cards and loans affect my mortgage amount?

    Yes, existing credit commitments reduce how much you can borrow. Lenders typically use 3% of your credit card balance as a monthly commitment, plus the actual monthly payments on loans and HP agreements. Paying off debts before applying can significantly increase your borrowing capacity.

    6

    Can first-time buyers borrow more than home movers?

    First-time buyers may have access to special schemes and some lenders offer enhanced income multiples for them. However, home movers with equity from a previous property often have larger deposits, which can unlock better rates and higher borrowing limits.

    7

    How can I increase my maximum loan?

    There are several ways to improve your borrowing capacity, depending on what's limiting you. If you're constrained by affordability (monthly stress test): extending your mortgage term lowers monthly payments and is often the simplest way to borrow more. Reducing credit card balances, paying off personal loans, or clearing your student loan will lower your monthly outgoings. Adding a joint applicant brings in a second income which can significantly increase what you can afford. Switching to interest-only (where available) also reduces the monthly stress test payment. If you're constrained by income multiple (LTI): some lenders offer higher multiples at lower LTVs, so increasing your deposit can unlock more borrowing. Professional schemes may also offer enhanced multiples. If you're constrained by loan-to-value (LTV): increasing your deposit directly raises your limit. Remember that each lender calculates differently — even small changes can shift which lenders you qualify with.
