Borrowing
Affordability assessment is not the same as a credit check
Lenders ask two separate questions: whether you repay debts, and whether you can afford this one. Passing one does not pass the other.
This works through affordability checks in the order the parts actually depend on each other.
The short version
- Creditworthiness and affordability are assessed separately.
- Committed expenditure and dependants reduce borrowing capacity substantially.
- Lenders stress-test repayments against higher rates.
Two different questions
A credit check asks whether you have repaid borrowing reliably in the past. An affordability assessment asks whether your income, minus commitments, can service this new borrowing. Someone with an excellent file and thin disposable income fails the second while passing the first, which feels arbitrary and is not.
What counts as committed expenditure
Existing loan and card repayments, childcare, maintenance payments, rent or mortgage, and often a modelled cost of living for household size. Available credit limits may also be treated as potential debt even when unused. Clearing a small loan before applying can free more capacity than an equivalent increase in income.
Stress testing is standard
Mortgage lenders in particular assess whether repayments remain affordable at a materially higher interest rate. That is why the amount offered is often well below what current rates alone would suggest.
It is a regulatory and prudential requirement rather than caution from an individual lender.
Income is assessed conservatively
Variable income, bonuses, overtime and self-employment are typically averaged or discounted. Self-employed applicants are usually asked for two or three years of accounts, which is why a recent change in status reduces borrowing capacity sharply. Documentation matters more than the headline figure here.
Improving the outcome
Reducing committed expenditure, closing unused credit facilities and avoiding new applications all help. So does timing: applying after two full years of stable, documented income is materially easier than applying at eighteen months. A broker adds value mainly by knowing which lenders treat your particular income shape generously.
The takeaway
Clear small commitments before you apply. Capacity is freed faster that way than by earning more.
Small and repeatable beats ambitious and abandoned, almost every time.
Questions readers ask
Why did the amount offered drop between application and offer?
Usually because verified figures differed from the estimates given, or committed expenditure was higher once statements were reviewed.
Does a bigger deposit improve affordability?
It reduces the loan and therefore the repayment, which helps. It does not change the assessment of your income and commitments.
