Affordability

Mortgage affordability and existing debts

Affordability is not only “income × a multiple”. Lenders subtract monthly commitments. That is why a modest salary with clean outgoings can support more than a higher salary with heavy cards and loans. This is general information from Property Money Limited — not advice.

The problem

Applicants often focus on boosting declared income by a few hundred pounds a month, while leaving high-balance revolving credit untouched. Under stress-tested affordability, those monthly commitments can reduce the maximum loan more than a small income bump increases it.

What usually matters

• Commitments to be repaid. Loans, hire purchase, car finance, student-style plans that appear on the file, and minimum card payments all feed the outgoings side.
• Less than 12 months remaining. Some lenders ignore or soften debts with under 12 months left — policy varies. Do not assume a near-finished loan is invisible.
• Debt-to-income shape. High monthly outgoings relative to income compress headroom even when the absolute balances look manageable.
• Capital raising for debt consolidation. Remortgaging to clear expensive revolving debt can improve future affordability — if the new loan still fits LTV, product and underwriting rules, and if clearing really happens.
• Clearing high pcm debts vs a tiny income bump. Paying off or reducing a large monthly commitment often moves the needle more than a small overtime or bonus discussion.

Paths that often help

• List every commitment with balance, monthly payment and months left — then model clearing vs keeping before you chase a higher income figure.
• Where consolidation is the plan, treat “cleared on completion” as a process with the solicitor and lender, not a verbal intention.
• Use an illustrative payment tool only for the mortgage side; it will not score your debts. See the mortgage calculator.
• Expect lenders to stress-test at a higher rate than the pay rate — commitments bite harder under that test.

Mortgagability in plain terms

Mortgagability here is residual income after commitments under the lender’s affordability model. Income opens the door; monthly debts often close it. Clearing versus keeping those debts can change the answer more than another £2,000 of annual income.

A practical way to think about it

Write down every commitment that shows on your credit file or leaves by direct debit: cars, loans, cards, buy-now-pay-later where it counts, and other property loans. Note the monthly payment and how many months remain.

Then ask two questions. First: if I cleared this one before applying, would the monthly saving be material? Second: can I clear it without creating a new problem — emptying the deposit, or taking a new loan that looks worse to an underwriter? Those questions are for you and, if you choose, for a regulated adviser. This website will not tell you which debt to pay first.

A mortgage you can afford on paper still leaves a separate question: who pays it if illness or death removes income? Use the protection gap analyser only as an illustration if useful.

Credit card available limits can matter even when the balance is low. Some underwriting uses a percentage of the limit. Reducing limits deliberately can help in some cases and can also nudge your score the wrong way if done badly — so treat it as a planned step, not a late-night tweak the night before you apply.

Student loans that appear as a salary deduction are handled differently from revolving consumer credit. Say how yours is collected. Car finance with a balloon payment needs the balloon visible in the plan if it falls inside the mortgage term you want.

Finally, remember that illustrative online “how much can I borrow” widgets almost never see your full commitment list. Treat them as entertainment until a real affordability assessment includes the debts you actually have.

Next step

Bring income and a commitment list. The interesting conversation is usually which debts to clear — not only how much you earn.
