Mortgage declined on affordability
Being declined on affordability usually means one lender's calculation said the payments did not fit your income and outgoings, not that no lender will lend. Lenders use different income multiples, stress rates and expenditure models, and treat variable income (bonus, commission, overtime) differently, so the same figures can pass elsewhere. Clearing short-term debt, a longer term, or a lender that counts more of your income can all change the answer.
Why one no is not the market's answer
Affordability is not a single national rule; it is each lender's own model. Income multiples, the stressed interest rate, and how household spending is estimated all vary. So does how much of your bonus, commission or overtime counts. The result is that the exact same applicant can be offered noticeably different amounts by different lenders, and a decline often just means you met the strictest model first.
Levers that genuinely move affordability
- Clear or reduce short-term debt: loans, credit cards and car finance directly cut your capacity.
- Consider a longer mortgage term to lower the monthly payment.
- Check whether a 5-year fix unlocks a gentler stress test with some lenders.
- Use a lender that counts more of your variable or second income.
Common questions
Why do affordability decisions differ so much?
Because lenders use different income multiples, different stress rates, and different assumptions about your outgoings. One lender may cap at a lower multiple or count less of your variable income; another may be more generous on both. The same salary and commitments can produce very different maximum loans.
Does how much of my income counts matter?
Hugely. If you have bonus, commission, overtime or a second income, the percentage a lender uses of each drives your affordability. A lender that counts more of your variable pay can approve a loan another lender rejects on identical payslips.
What can I do to improve affordability?
Reduce or clear short-term debts (loans, card balances, car finance), since these cut your borrowing capacity directly. Consider a longer term to lower the monthly cost, and check whether a 5-year fix unlocks a gentler stress test. A broker can find the lender whose model fits you best.
Is being declined on affordability about bad credit?
No, they are different. Affordability is about whether the lender thinks the payments fit your income and outgoings, regardless of your credit history. You can have a perfect credit file and still be declined on one lender's affordability model.
If variable pay is the issue, see complex income.
