To borrow £700,000, you would typically need a household income of around £155,556 if a lender offered 4.5 times your income. At 4 times income, you would need £175,000, while a lender willing to consider 5 times income could potentially lend £700,000 on an income of £140,000.
However, income multiples are only a starting point. At this level of borrowing, your deposit, existing debts and financial commitments, mortgage term, credit profile and the way you earn your income can all have a significant impact on how much a lender is prepared to offer.
At Oportfolio Mortgages, we assess larger mortgage applications across high-street, specialist and, where appropriate, private banking options. This guide combines typical income multiples with the factors lenders use when assessing £700,000 mortgage applications in practice.

£700k Mortgage Salary Calculator (Typical UK Lender Multiples)
Income multiples of around 4–4.5 times income are a useful starting point when estimating how much you might be able to borrow, although some lenders can consider higher multiples for eligible borrowers.
Here’s a typical guide:
| Income multiple (rule-of-thumb) | Approx salary needed (single or joint household income) | ||||
|---|---|---|---|---|---|
| 4.0x | £175,000 | ||||
| 4.5x | £155,556 | ||||
| 5.0x | £140,000 | ||||
| 5.5x | £127,273 | ||||
| 6.0x | £116,667 |
These figures are illustrative. A lender offering a particular income multiple does not guarantee that £700,000 will be available, as borrowing will depend on its full affordability assessment and lending criteria.
Can you afford a £700k mortgage?
Mortgage affordability isn’t determined by salary alone. Your deposit, existing financial commitments, credit profile, mortgage term and income structure can all affect how much you can borrow.

Why the income multiple is only a starting point
Many lenders use an income multiple as an initial indication of borrowing capacity, but this does not determine the final mortgage amount.
Some lenders can consider income multiples above the more typical 4–4.5x range, but eligibility varies significantly. Depending on the lender and product, factors can include:
- Total household income
- Profession and employment type
- Bonus, commission or other variable income
- Existing debts and monthly commitments
- Number of dependants
- Mortgage term
- Deposit and loan-to-value
- Overall credit profile
Lenders also have restrictions around higher loan-to-income lending, so access to 5x, 5.5x or 6x income should not be assumed simply because your salary meets a particular threshold.
What “£700k mortgage” actually means
When people search this, they usually mean a £700,000 loan amount, not the purchase price.
Examples:
- Property £800,000 with £100,000 deposit → £700,000 mortgage (87.5% LTV)
- Property £875,000 with £175,000 deposit → £700,000 mortgage (80% LTV)
- £1,000,000 property + £300,000 deposit → £700,000 mortgage (70% LTV)
The resulting loan-to-value (LTV) can affect:
- The mortgage products and rates available
- Lender choice
- Some aspects of lender criteria and affordability
A larger deposit reduces the loan-to-value (LTV), which can potentially provide access to a wider range of products and more competitive interest rates. However, the lender will still need to establish that the £700,000 mortgage itself is affordable.
How different types of income can be assessed
For a £700,000 mortgage, the amount you earn is only part of the picture. How you earn that income can also influence which lenders are suitable and how much of your earnings can be used for affordability.
This can be particularly important for higher earners whose remuneration is made up of a combination of basic salary, bonuses, commission, dividends, company profits or contractor income.
Basic salary
Usually the simplest part of income for lenders to assess, although affordability will still depend on commitments and other circumstances.
Bonus and commission
Different lenders can take different approaches to regular bonus and commission income. Some may use an average over a period of time, while others can consider a proportion of recent payments depending on their criteria.
Self-employed income
Assessment can vary depending on whether someone is a sole trader, partner or company director. Different lenders may use salary and dividends, net profit or other measures when assessing affordability.
Contractor income
Some lenders have specific approaches for contractors and may consider day rates or contract value rather than relying solely on conventional employed-income calculations.
Multiple income sources
This is one reason two applicants with the same total annual income can receive very different borrowing figures from different lenders. Matching the way your income is structured to a lender that assesses it favourably can be particularly important when trying to borrow £700,000.
Can I get a £700k mortgage on my salary?
Whether £700,000 is achievable depends on much more than your headline salary, but comparing the mortgage against your household income provides a useful starting point.
The examples below show the income multiple that would be required at different salary levels.
Can I get a £700k mortgage on £120k?
A £700,000 mortgage on a household income of £120,000 would require borrowing of approximately 5.83 times income.
This is considerably above the more typical income multiples used as a starting point by many lenders. Some lenders can consider higher multiples for eligible borrowers, but your overall affordability, income structure, existing commitments, mortgage term and other lending criteria would all need to support this level of borrowing.
Can I get a £700k mortgage on £130k?
On a household income of £130,000, borrowing £700,000 would require approximately 5.38 times income.
This may be possible for some borrowers through lenders that can consider higher income multiples, but it should not be assumed that £700,000 will automatically be available. The lender will still carry out its full affordability assessment.
Can I get a £700k mortgage on £140k?
A £700,000 mortgage represents exactly 5 times a £140,000 household income.
Some lenders can consider borrowing at this level for applicants who meet their eligibility and affordability requirements. Existing debts, dependants, mortgage term, deposit and the structure of your income can all influence the amount actually available.
Can I get a £700k mortgage on £150k?
On a household income of £150,000, a £700,000 mortgage represents approximately 4.67 times income.
This is closer to the income-multiple range available from a wider selection of lenders, although £700,000 would still need to pass the lender’s full affordability assessment.
Can I get a £700k mortgage on £160k?
A household income of £160,000 would require borrowing of approximately 4.38 times income to reach a £700,000 mortgage.
While this sits within the broad income-multiple range considered by many lenders, affordability is not guaranteed. Monthly commitments, dependants, mortgage term, credit profile and the way your income is earned will still be assessed.
Can I get a £700k mortgage on £175k?
At £175,000 household income, a £700,000 mortgage represents exactly 4 times income.
This provides a stronger starting point from an income-multiple perspective, but lenders will still assess the application against their individual affordability and lending criteria before determining the maximum mortgage available.
Getting a £700k mortgage as a high earner
Higher earners do not always receive all of their income as a straightforward basic salary. Bonuses, commission, dividends, partnership income and other forms of remuneration can make up a significant proportion of total earnings.
For example, someone earning a £150,000 basic salary may be assessed differently from someone receiving a £100,000 basic salary plus £50,000 in annual bonus or commission, even though both have total annual earnings of £150,000.
Different lenders have different approaches to variable and complex income. The amount they are prepared to use, the evidence required and the period over which income is assessed can vary.
This means lender selection can become particularly important for high earners seeking a £700,000 mortgage. An applicant who falls short of the required borrowing with one lender may receive a different affordability result elsewhere because of the way their income and overall circumstances are assessed.
If a significant proportion of your earnings comes from bonus or commission income, or you are self-employed, a company director or a contractor, it can be useful to establish how lenders are likely to assess your income before making an application.
A real large mortgage case handled by Oportfolio
Property value: £875,000
Deposit: £175,000
Mortgage required: £700,000
Income: £160,000
Income type: Company director – salary and dividends
The challenge
The client needed a £700,000 mortgage to complete the purchase of an £875,000 property. Although their total income was around £160,000, the average salary and dividends used by some lenders did not produce enough borrowing to reach the required mortgage amount.
How Oportfolio helped
We reviewed the client’s company accounts and wider financial position rather than relying solely on their salary and dividend drawings. We identified a lender that could consider borrowing at up to five times income and was also prepared to take the company’s retained profits into account when assessing affordability.
The outcome
By using a lender whose criteria were better suited to the client’s company-director income structure, we were able to secure the required £700,000 mortgage, allowing the client to proceed with the purchase of their £875,000 property.
This case shows why company directors should not assume their mortgage affordability is limited to a simple calculation based on salary and dividends. Some lenders can take a broader view of company income, depending on their criteria and the strength of the business.
Is £700k considered a large mortgage?
There is no single mortgage amount at which every lender begins to classify an application as a “large mortgage”. However, borrowing £700,000 can bring additional considerations into lender selection compared with a smaller mortgage.
Lenders can have different maximum loan sizes, loan-to-value limits and affordability criteria, while higher earners may also need a lender that can appropriately assess bonuses, commission, self-employed income or other more complex remuneration.
For this reason, the lender offering the most suitable option for a £300,000 mortgage will not necessarily be the lender offering the most suitable solution for a £700,000 mortgage.
Oportfolio regularly works with clients seeking higher-value borrowing, including professionals, business owners and clients purchasing property in London and across the UK. You can read more in our guide to large mortgages in the UK.
Ways to improve your mortgage affordability
If your initial affordability falls short of £700,000, there are several areas that may be worth exploring depending on your circumstances:
- Reduce existing credit commitments where appropriate
- Consider whether a longer mortgage term is suitable
- Ensure all eligible bonus, commission and variable income is considered
- Explore lenders whose affordability criteria suit your income structure
- Consider a joint application where appropriate
- Increase your deposit if this reduces the amount you need to borrow
Because affordability models vary between lenders, choosing a lender whose criteria suit your circumstances can make a significant difference at higher borrowing levels.
How much does a £700k mortgage cost per month?
| Interest Rate | 25-Year Term | 30-Year Term | 35-Year Term |
|---|---|---|---|
| 4% | £3,695 | £3,342 | £3,099 |
| 4.5% | £3,891 | £3,547 | £3,313 |
| 5% | £4,092 | £3,758 | £3,533 |
| 5.5% | £4,299 | £3,975 | £3,759 |
| 6% | £4,510 | £4,197 | £3,991 |
Figures are illustrative and assume a £700,000 capital-and-interest repayment mortgage with the interest rate remaining unchanged throughout the term. They do not include fees or other costs. Actual mortgage rates and repayments will vary.

FAQ: What Salary Do I Need for a £700k Mortgage in the UK?
Can I get a £700k mortgage on £120k salary?
A £700,000 mortgage on £120,000 household income would require borrowing of approximately 5.83 times income. Some lenders can consider higher income multiples for eligible borrowers, but availability will depend on your income structure, existing commitments, deposit, mortgage term and overall affordability.
Can I get a £700k mortgage on a £140k salary?
A £700,000 mortgage represents exactly 5 times a £140,000 household income. Some lenders can consider borrowing at this level where their eligibility and affordability requirements are met, although a 5 times income mortgage should not be assumed to be available to every applicant.
How much deposit do I need if I want a £700k mortgage?
The deposit required depends on the value of the property because £700,000 refers to the mortgage amount rather than the purchase price. For example, buying an £875,000 property with a £175,000 deposit would leave a £700,000 mortgage at 80% loan-to-value (LTV). A larger deposit can reduce the LTV and potentially provide access to a wider range of mortgage products and rates.
Can two people combine their salaries for a £700k mortgage?
Yes. On a joint mortgage application, lenders can consider the incomes of both applicants when assessing affordability. For example, two applicants earning £80,000 each would have a combined household income of £160,000, making a £700,000 mortgage approximately 4.38 times their combined income. Both applicants' financial commitments and circumstances will also be assessed.
Can I get a £700k mortgage if I'm self-employed?
Yes. Self-employed applicants can obtain £700,000 mortgages, although the way income is assessed varies between lenders. Depending on your business structure, lenders may consider salary and dividends, profits or other measures of income, alongside your trading history and supporting financial documents.
Can I get a £700k mortgage at 5 or 6 times my salary?
Some lenders can consider higher income multiples for borrowers who meet particular eligibility and affordability requirements. A £700,000 mortgage at 5 times income would require £140,000 of household income, while at 6 times income it would require approximately £116,667. Higher income multiples are not universally available and remain subject to the lender's full affordability assessment.
How much would a £700k mortgage cost per month?
The monthly cost depends on the interest rate and mortgage term. As an illustration, a £700,000 capital-and-interest repayment mortgage at 5% would cost approximately £4,092 per month over 25 years, £3,758 over 30 years or £3,532 over 35 years. Actual mortgage rates and repayments will vary, and fees and other costs should also be considered.
