If you’re a first-time homebuyer, one of the most pressing questions on your mind is probably: “How much do I need to earn to get a mortgage?” It’s a reasonable question, as buying a home is one of the largest and most significant financial steps in your life, and you want to know if it’s possible to do so on your salary. However, it’s not just some easy calculations of your income. And now lenders actually test affordability, examine how you spend, and even stress-test your finances to see if you can manage higher interest rates. Let’s break it down.

How Lenders Assess Income

When you apply for a mortgage, your income is one of the factors that lenders consider before deciding whether they can lend to you. The old rule of thumb is that you can borrow about four and a half times your salary. That’s still a decent rule of thumb, but things are more complex now.

Lenders don’t simply multiply your salary; they carry out affordability checks. They will see your income against your financial obligations, such as personal loans, car finance or credit card balances. If you have child care costs or dependents, those are also considered, because they lower your disposable income.

Lenders also use stress tests. This means that they check that you would still be able to afford your mortgage if the interest rates were to rise by a few percentage points. If your budget appears too strained with those kinds of terms, they might impose a limit on how much they’ll lend to you.

So while your income provides the foundation, other aspects of your lifestyle, costs and financial obligations also figure into how much you can borrow.

Minimum Income for a Mortgage

There is no hard minimum income you need to secure a mortgage. It depends on the price of the property you’re considering buying and the size of the deposit you have saved. Technically, even someone earning £15,000 a year could secure a small mortgage if they had a large deposit.

In practice, many lenders prefer applicants to have an income that comfortably covers day-to-day expenses as well as mortgage repayments, although there is no official minimum salary requirement. This is because it creates a more realistic picture of what a borrower can afford after all essential outgoings are considered.

Partnership applications work a bit differently. Lenders combine the income of both applicants before applying the income multiple. This can be an enormous difference. A couple with two £20,000 incomes could, in theory, borrow up to about £180,000 together, compared with about £90,000 if only one applied in their own name. Please note: actual borrowing limits vary by lender and individual circumstances.

Worked Examples

So you have a better idea, take a look at the examples below to see what varying incomes may amount to when you use the standard rule of four and a half times your salary.

£25,000 salary = Maximum borrowing of potentially around £112,500.

£35,000 salary = Maximum borrowing of potentially around £157,500.

£50,000 salary = Maximum borrowing of potentially around £225,000.

A couple earning £30,000 each = A combined salary of £60,000, with potential borrowing up to £270,000.

While these numbers can be a helpful starting point, they’re not set in stone. Other factors, such as your deposit and whether you have any debt, will determine how much you end up borrowing, as will your monthly spending and even the lender you choose.

For instance, a person earning £35,000 with no loans and a 15% deposit could be approved for the higher end of the range. But someone who earns the same but has two car loans and high monthly bills may receive less.

Deposit Size & Its Impact

Lenders don’t just look at your income; your deposit is just as important. In the UK, the minimum deposit required for most first-time buyers is 5%, with help from the government in the form of schemes (subject to eligibility).In other words, if you want to buy a £200,000 home, you’d have to have at least £10,000 in savings.

But even though 5% is the lowest, it doesn’t always lead to the best outcome. If you can find your way to a 10% or even 20% deposit, you’ll typically have access to more lenders and lower interest rates. The impact that has on what you repay each month can add up over the life of the mortgage.

If you’re buying a property for £200,000, for example, you would need a £10,000 deposit, 5 per cent of the price, and the mortgage would be for £190,000. From a 20% deposit, you’d need £40,000, and the mortgage would total only £160,000. That translates into lower monthly repayments and less overall interest.

While the pressure to save a larger deposit may feel like an insurmountable task, it can give you a significant advantage when it comes to what you can afford.

Self-Employed Buyers

If you’re self-employed, the rules are somewhat different. Potential lenders would like confidence that your income is stable and sustainable. Broadly speaking, they will ask for a couple of years of accounts or SA302 forms from HMRC to show your earnings.

Whereas for limited company directors, lenders tend to take a combination of your salary and dividends. Contractors might be rated in another way, depending on the lender, who could multiply out your day rate by the length of your contract to generate an annual income.

The good news is that today there are more options open to self-employed buyers than in the past. Some lenders may be willing to accept only 12 months’ worth of trading history if everything else is strong.

If you are, it may be worth speaking to a broker who specialises in self-employed mortgages, as the criteria can vary hugely from lender to lender.

Other Affordability Factors

In addition to income and deposit, lenders will consider your overall finances. Your credit history is a big factor; missed payments or defaults can make it more difficult to borrow, though not always impossible.

They’ll also look for any existing debts, such as loans you haven’t repaid in full, car finance or credit card debts. The more you have to commit each month, the less “disposable” income you will seem to have to pay a mortgage.

Day-to-day spending is another factor. They want to ensure that your budget has sufficient funds to cover the mortgage, as well as all bills, food, and other necessities. Even the kind of property you are buying can make a difference, with some lenders wary of non-standard construction or certain leasehold arrangements.

All of these checks may seem intrusive, but they’re aimed at ensuring you can afford your mortgage.

Conclusion

There is no universal answer to how much money you need for a first-time buyer mortgage. That’s determined by your salary, your deposit and how your overall finances shape up. Higher or more stable incomes can make the mortgage process smoother, although there is no fixed income threshold for first-time buyers.

If you want personal advice, Mortgaged can help explain how your income, deposit and spending add up to borrowing potential, and get you closer to owning your first home.

Your home/property may be repossessed if you do not keep up repayments on a mortgage or other debt secured on it.

There may be a fee for mortgage advice. The precise amount will depend upon your circumstances and will be agreed with you before proceeding, but we estimate it will be £395.
