Why Two People With the Same Salary Can Borrow Different Amounts
Two people earning the same salary can borrow very different mortgage amounts, here’s why, and how to improve your chances.
It sounds logical: if two people earn the same, they should be able to borrow the same amount. But in the mortgage world, that’s rarely the case. Lenders dig much deeper than income alone when working out affordability.
Here’s why borrowing power can look so different — even when salaries are identical.
Different outgoings, different affordability
One buyer might have car loans, childcare, and credit cards; the other may have none. The more committed outgoings you have, the less disposable income you can put towards a mortgage.
Credit history matters
Two people on the same salary can look very different on paper depending on how they’ve managed credit. A clean record with consistent repayments builds more confidence than missed payments.
Dependants and family setup
Having children or financial dependants affects affordability. It’s not just about income — it’s about how far that income stretches.
Employment type
A permanent job in the same role for years is assessed differently from a brand-new job or self-employment, even at the same income level.
Lifestyle and spending patterns
Some lenders review bank statements closely. Consistent overspending or gambling can reduce confidence, even if income looks fine.
The Bottom Line
Same salary doesn’t mean same outcome. Affordability is about the whole picture. Understanding how lenders see you can help you prepare your case more effectively.
Your home may be repossessed if you do not keep up repayments on your mortgage or other loan secured against it.
