How much can I borrow for a mortgage?

Most lenders in the UK will let you borrow somewhere between 4 and 4.5 times your annual income. Some will stretch to 5 times or more if your situation is right. So if you earn £50,000, a typical starting point is around £200,000 to £225,000, though the real figure can be higher or lower once a lender looks at the full picture.

That full picture is the part most people miss. Your income sets the ceiling, but it's everything else that decides where you actually land. Here's how it works, in plain English.

The short answer

As a rough guide, take your annual income and multiply it by 4.5. If you and a partner are buying together, lenders usually combine both incomes.

So a couple earning £40,000 and £30,000 might borrow around £315,000 as a starting estimate. Add your deposit on top and that's roughly the property price you could be looking at.

It's only ever a starting point though. Two people on identical salaries can be offered very different amounts, and that catches a lot of buyers off guard.

What is an income multiple?

An income multiple is simply the number a lender multiplies your income by to set a maximum loan. For years the standard has been about 4.5 times income.

The good news is that more lenders now offer higher multiples in the right circumstances. Some will go to 5 or even 5.5 times income for higher earners, and certain first-time buyer schemes and professional mortgages (for example for doctors, accountants, or solicitors) can push higher still.

You won't always qualify for the top of that range, but it's worth knowing the door is open. The difference between 4.5 and 5.5 times income can be tens of thousands of pounds.

Why two people on the same salary can borrow different amounts

Lenders don't just look at what you earn. They look at what you have left over after your commitments. This is called an affordability assessment, and it's where the real number is decided.

A few things make a big difference:

• Your regular debts. Car finance, loans, credit cards, and even student loan repayments all reduce what you can borrow. As a rough idea, £500 a month of existing debt can knock somewhere around £100,000 off your maximum loan.
• People who depend on you. Children and childcare costs are taken into account.
• Your income type. Salaried, self-employed, bonus, commission, and overtime are all treated differently.
• Your credit history. A strong record opens up more lenders and better rates.

So someone on £50,000 with no debts and no dependents can often borrow noticeably more than someone on the same salary with a car loan and two children.

How your deposit changes things

Your deposit matters more than people expect. Lenders talk about loan to value, or LTV, which is just the size of your loan compared with the property price.

Most lenders will lend up to 90% of the value, so you'd need a 10% deposit. Some go to 95%, meaning a 5% deposit. The bigger your deposit, the more lenders will compete for you and the better the rates you'll be offered.

Here in Edgware and across North London and Hertfordshire, where prices sit above the national average, a slightly larger deposit can make a real difference to what's within reach.

Can you borrow more than 4.5 times your income?

Often, yes. It depends on the lender, your deposit, your income, and how clean your finances look.

Higher multiples tend to be available to people with larger deposits, strong credit, secure employment, or higher incomes. There are also schemes aimed specifically at first-time buyers that allow more generous borrowing.

This is exactly where it pays to look beyond your own bank. One lender might cap you at 4.5 times income while another, looking at the very same situation, offers 5 times. Matching the right lender to your circumstances is usually where the biggest gains are found.

How to borrow more without overstretching

If you want to give yourself the best chance of a higher offer:

• Clear or reduce existing debts before you apply.
• Check your credit report and get on the electoral roll.
• Save a little more deposit if you can. Even moving from 10% to 15% helps.
• Avoid big new financial commitments in the months before applying.

The aim is never to borrow the absolute maximum. It's to borrow a comfortable amount that still leaves you breathing room each month. Your home may be repossessed if you do not keep up repayments on a mortgage secured against it, so the right number is one you can afford in good months and tighter ones alike.

A quick example

Say you earn £55,000 and your partner earns £35,000, a combined income of £90,000.

At 4.5 times income that's a maximum of around £405,000. With a 10% deposit of £45,000, you'd be looking at homes up to roughly £450,000.

If a lender offered 5 times income instead, that maximum jumps to £450,000, taking your buying range closer to £495,000 with the same deposit. Same couple, same salary, a very different result depending on the lender.

That's the real value of expert mortgage advice. Not just running a calculator, but knowing which lender will say yes to the most, for you.

Common questions

How much can I borrow on a £40,000 salary? Around £160,000 to £180,000 on your own as a starting estimate, using a 4 to 4.5 times income guide. The exact figure depends on your deposit, debts, and outgoings.

Does a mortgage broker help me borrow more? A broker can search across lenders whose criteria suit your situation, including those offering higher income multiples. That can mean a larger or more affordable loan than going to a single bank.

Do my debts affect how much I can borrow? Yes. Lenders subtract your regular commitments before working out your loan, so clearing debts before you apply can increase what you can borrow.

Can I borrow 5 times my income? Some lenders offer 5 times income or more in the right circumstances, usually for higher earners, larger deposits, or certain professions. It isn't guaranteed, but it's increasingly available.

How accurate are online borrowing calculators? They give a useful rough guide based on income multiples, but they don't reflect a lender's full affordability check, so your real figure can differ.
