How much can I actually borrow for a mortgage? 🏡
It's probably one of the questions I get asked the most.
And unfortunately, it's not as simple as taking your salary and multiplying it by 4 or 4.5.
Two people earning exactly the same amount could potentially have very different mortgage affordability.
Why?
Because lenders look at much more than just your salary.
Your deposit, credit commitments, childcare, loans, car finance and even how your income is made up can all make a difference.
Self-employed?
Receiving benefit income?
Overtime?
Bonus or commission?
Different mortgage lenders can treat these types of income differently — and their affordability calculations aren't all the same either.
That's why an online mortgage calculator can be useful for a rough idea, but it isn't necessarily your answer.
Sometimes it's not about whether you can borrow enough.
It's about finding the lender whose criteria fit your circumstances.
So if you're thinking about buying a home and wondering “How much mortgage can I borrow?”, don't rely on a calculator alone.
