Mortgage income multiples are one of the ways lenders work out how much you may be able to borrow. You will often hear mortgages described as 4 times salary, 4.5 times income or even 5 or 6 times income.
However, the income multiple is only part of the calculation. Mortgage lenders also carry out an affordability assessment that considers your outgoings, debts, mortgage term and other circumstances.
This means two people earning exactly the same amount may be offered very different mortgage amounts.

What are mortgage income multiples?
A mortgage income multiple, also called a loan-to-income ratio or LTI, compares the amount you want to borrow with the annual income the lender accepts for the application.
For example, if a lender was prepared to lend four times your income:
- Annual income: £30,000
- Income multiple: 4x
- Maximum based on the multiple alone: £120,000
If the same applicant qualified for five times income, the figure based on income alone would increase to £150,000.
That does not mean the lender will necessarily offer the full amount. The application still has to pass its affordability assessment, credit checks, loan-to-value requirements and wider lending criteria.
What mortgage income multiples are available?
There is no single income multiple that applies across the UK mortgage market.
You will commonly see maximum LTIs around:
- 4x income
- 4.49x or 4.5x income
- 5x income
- 5.5x income
- 6x income
Some lenders currently go above 6 times income for particular applicants or mortgage types.
The maximum available to you can depend on factors including your income, deposit, credit profile, mortgage term, whether you are a first-time buyer and the lender or product you use.
Why do so many lenders use 4.49 times income?
You may notice that mortgage lenders often quote a maximum of 4.49 times income rather than 4.5.
This is because, for the relevant UK regulatory measure, mortgages at 4.5 times income or above are classed as high loan-to-income lending.
This does not mean 4.5 times income is a legal maximum for an individual borrower. Mortgages above this level are widely available, subject to the lender’s criteria and affordability assessment.
Can I get a mortgage at 5 times my income?
Yes. Mortgages at five times income are available from a number of lenders.
Whether you qualify depends on the lender. Some reserve higher income multiples for applicants earning above a particular amount, while others offer enhanced LTIs to first-time buyers or applicants with particular loan-to-value ratios.
Your existing financial commitments can also mean that you qualify for less than the lender’s published maximum.
Can I get a mortgage at 5.5 times my income?
Yes. A number of mainstream lenders currently offer mortgages at up to 5.5 times income for applicants who meet their criteria.
These are no longer limited only to extremely high earners. Some lenders now have specific first-time buyer propositions that allow 5.5 times income at comparatively modest household income levels.
However, a maximum LTI is not the same as guaranteed borrowing. You must still pass the lender’s affordability and credit assessments.
Can I get a mortgage at 6 times my income?
Yes, 6 times income mortgages are available in the current market.
They are more restricted than mortgages around 4 to 4.5 times income and are usually available only where particular criteria are met.
For example, Nationwide currently publishes maximum LTIs of up to 6 times income for its Helping Hand proposition and selected high-income purchase or remortgage applications.
Other lenders offer enhanced income multiples through particular first-time buyer, professional or higher-income propositions.
Can you borrow more than 6 times income?
In some circumstances, yes.
For example, HSBC currently publishes a maximum LTI of up to 6.5 times income for qualifying HSBC Premier customers at up to 90% LTV.
Nationwide also currently publishes a maximum of 6.5 times income for some like-for-like repayment remortgages.
These are specialist eligibility routes rather than normal borrowing limits available to everybody.
Claims that you automatically need a private bank or must be a high-net-worth individual to borrow above 6 times income are therefore no longer accurate across the whole mortgage market.
Current lender mortgage income multiple examples
The examples below show how much lender criteria can vary. They are based on published lender criteria checked on 6 October 2026 and can change at any time.
| Lender | Example maximum LTI | Example current criteria |
|---|---|---|
| Nationwide | Up to 6x | Helping Hand and selected high-income purchase/remortgage cases can reach 6x. Standard LTI is currently up to 4.49x. |
| HSBC | Up to 6.5x | Qualifying Premier customers can reach 6.5x at up to 90% LTV. Qualifying first-time buyers can reach 5.5x. |
| Halifax | Up to 5.5x | First-Time Buyer Boost can offer up to 5.5x where application income is at least £40,000 and LTV is 90% or below. Some standard applications can also reach 5.5x. |
| Accord Mortgages | Up to 5.5x | First-time buyers can access up to 5.5x subject to criteria, with options available up to 95% LTV. Higher-LTI options also exist for some non-first-time buyers. |
| Skipton Building Society | Up to 5.5x+, depending on product | Higher-LTI lending is available through its LTI Booster range. For lending above 4.49x, current minimum income is £40,000 for sole applicants and £60,000 for joint applicants, subject to LTV and product criteria. |
These are maximum income multiples, not guaranteed borrowing amounts. The lender’s affordability calculator may produce a lower figure once your income, expenditure and other commitments have been assessed.
What changed with higher income multiple mortgages in 2025?
The UK mortgage market became more flexible around higher loan-to-income lending during 2025.
For regulatory purposes, a mortgage at 4.5 times income or above is treated as high-LTI lending.
Historically, larger lenders were generally expected to limit mortgages at or above this level to 15% of their new residential mortgage lending.
Several changes were introduced during 2025.
More flexibility for lender stress testing
In March 2025, the FCA reminded lenders that its mortgage affordability rules already allowed them flexibility when choosing the interest rate used to stress-test affordability.
As lenders changed their affordability models, borrowing capacity increased for some applicants.
This can make it easier for a borrower to qualify for a higher mortgage even where the lender’s maximum income multiple itself has not changed.
Changes to high loan-to-income lending
From 11 July 2025, the regulatory threshold below which lenders are exempt from the high-LTI flow measure increased from £100 million to £150 million of annual residential mortgage lending.
The Financial Policy Committee also recommended giving individual lenders greater freedom to make more than 15% of their own lending at 4.5 times income or above, while aiming to keep high-LTI lending consistent with a 15% limit across the mortgage market overall.
Interim arrangements currently allow participating lenders greater flexibility while the PRA and FCA develop the permanent framework.
As at 6 October 2026, those interim arrangements are due to remain available until the new rules take effect or 31 December 2026, whichever happens first.
For borrowers, the important point is that 4.5 times income is not an individual legal borrowing cap. Higher income multiple mortgages are an established part of the current market.

Mortgage income multiple examples
The table below shows the simple calculation at different income levels. It is for illustration only and does not mean that every applicant earning the amount shown will qualify for the corresponding mortgage.
| Annual income | 4x | 4.5x | 5x | 5.5x | 6x |
|---|---|---|---|---|---|
| £25,000 | £100,000 | £112,500 | £125,000 | £137,500 | £150,000 |
| £30,000 | £120,000 | £135,000 | £150,000 | £165,000 | £180,000 |
| £40,000 | £160,000 | £180,000 | £200,000 | £220,000 | £240,000 |
| £50,000 | £200,000 | £225,000 | £250,000 | £275,000 | £300,000 |
| £75,000 | £300,000 | £337,500 | £375,000 | £412,500 | £450,000 |
| £100,000 | £400,000 | £450,000 | £500,000 | £550,000 | £600,000 |
For a joint mortgage, the calculation is normally based on the combined eligible income accepted by the lender rather than applying the multiple separately to each applicant.
What affects the income multiple a lender will offer?
A lender’s published maximum LTI is only one part of the decision. Several factors can affect whether you can actually borrow at that level.
1. Your income
Some lenders offer higher income multiples once applicants reach certain income levels.
Others have enhanced propositions specifically for first-time buyers or other groups without requiring a particularly high salary.
The relevant figure is also the income the lender is prepared to accept, which may not be identical to the total income you receive.
2. Your deposit and loan-to-value
Your deposit determines the mortgage’s loan-to-value ratio.
Lenders often have different maximum income multiples at different LTVs. A borrower may therefore be eligible for a higher LTI with a larger deposit.
However, there is no general rule that you need a 15% deposit to get a mortgage at five times income.
For example, some current lender propositions offer 5.5 times income at 90% LTV, while Accord currently has options for qualifying first-time buyers up to 5.5 times income at as much as 95% LTV.
3. Your existing debts and financial commitments
Loans, credit cards, car finance, childcare, maintenance payments and other commitments can reduce how much mortgage you can afford.
You might therefore meet the lender’s criteria for a maximum LTI of 5.5 times income but receive a lower mortgage because its affordability calculation produces a smaller figure.
This is an important distinction: the income multiple is a maximum cap, not a promise to lend that amount.
4. The mortgage term
A longer mortgage term usually reduces the monthly repayment, which can improve the result of an affordability calculation.
However, a longer term does not necessarily increase the lender’s maximum permitted income multiple.
It can also substantially increase the total interest paid over the life of the mortgage.
5. Your credit profile
Your credit profile can affect the maximum LTI available.
Some lenders explicitly reduce their published income multiple where the applicant’s credit score or overall credit profile does not meet the requirements for the higher level.
For example, Halifax states that some applications that would otherwise qualify for 5.5 times income can be restricted to 5 times or to its standard LTI depending on the credit assessment.
6. The mortgage product or scheme
Higher income multiples are sometimes linked to particular mortgage products or schemes rather than being available across a lender’s entire range.
Examples include first-time buyer boosts, higher-LTI product ranges and propositions such as Nationwide Helping Hand.
Some higher-LTI products may also have different interest rates or fees, so the maximum amount you can borrow should not be your only consideration.
What income can lenders use for an income multiple?
Your basic salary is not necessarily the only income that can support a mortgage.
Depending on the lender and how sustainable the income is, it may consider:
- Basic salary.
- Overtime.
- Bonuses.
- Commission.
- Income from a second job.
- Self-employed earnings.
- Pension income.
- Rental income.
- Investment income.
- Certain benefits.
- Maintenance income in some circumstances.
Different lenders can use different percentages of these income sources.
For example, one lender may accept all of a regular bonus while another uses only a percentage or requires a longer history before including it.
This can materially change both your accepted income and the mortgage available under an income multiple.
How do mortgage income multiples work if you are self-employed?
Self-employed applicants can access the same types of income multiples as employed borrowers, subject to lender criteria.
The difference is usually how the lender establishes your qualifying income.
Sole traders and partnerships
Lenders may use taxable profit or your share of partnership profits when assessing income.
Some use an average over two or more years, while others may use the latest year’s figures where their criteria allow it.
Limited company directors
Depending on the lender, income can be assessed using:
- Salary and dividends.
- Salary plus a share of company net profit.
- Other measures of sustainable company income where the lender’s criteria permit this.
This can make a significant difference for directors who retain profit within their company rather than withdrawing it all as dividends.
There is no universal rule saying every self-employed applicant needs two or three full years of accounts. Some lenders can consider a shorter trading history.
Read our self-employed mortgage guide for more information.
Do lenders take your spending into account as well as the income multiple?
Yes.
Income multiples should not be confused with mortgage affordability.
A lender may have a maximum LTI of 5.5 times income, but it will still assess whether the mortgage is affordable once your financial commitments and household expenditure have been considered.
Committed expenditure can include:
- Personal loans.
- Credit cards.
- Car finance.
- Childcare.
- Maintenance payments.
- Other mortgages.
- Ground rent and service charges.
Lenders may also allow for normal household and living expenses when carrying out their affordability assessment.
Simply cutting supermarket spending or cancelling a subscription immediately before applying does not automatically increase the income multiple a lender will offer.
Does the property affect your income multiple?
The property can affect whether a lender is willing to offer the mortgage, but it does not necessarily change the actual income multiple.
Properties such as non-standard construction homes, high-rise flats, flats above commercial premises and some unusual property types can be subject to different loan-to-value or lending restrictions.
This may reduce the amount available even where your income would support a larger mortgage.
The lender will therefore consider both you as the borrower and the property being used as security.
Is a higher mortgage income multiple always better?
Not necessarily.
A higher income multiple can allow you to borrow more and potentially buy a more expensive property, but it also means taking on a larger debt.
Before choosing a mortgage purely because it provides the highest borrowing amount, consider:
- The monthly mortgage payment.
- The interest rate.
- Product fees.
- The mortgage term.
- The total amount repayable.
- How comfortable the payments would remain if your circumstances changed.
Some higher-LTI mortgage products may be priced differently from the lender’s standard range.
The right mortgage is therefore not necessarily the one that lets you borrow the most.
How can I improve my chances of getting a higher income multiple?
If you need to borrow at a higher multiple, there are a few areas worth looking at before applying.
- Reduce significant credit commitments where it makes financial sense.
- Build your deposit, as some lenders allow higher LTIs at lower loan-to-value ratios.
- Make sure all acceptable income is included, including sustainable bonuses, overtime or additional income.
- Check your credit reports for mistakes or issues before applying.
- Consider the mortgage term carefully, as a longer term may improve monthly affordability.
- Compare lenders, because their income multiples and affordability calculations differ substantially.
Do not take on a longer mortgage term or clear debts solely to reach a particular income multiple without considering whether doing so is appropriate for your finances overall.
How can a mortgage broker help with higher income multiples?
The main difficulty with higher income multiple mortgages is that lender criteria vary significantly.
One lender may cap your application at 4.49 times income while another could potentially consider 5, 5.5 or 6 times income.

Frequently asked questions about mortgage income multiples
What is the usual mortgage income multiple?
Around 4 to 4.5 times income remains a useful general guide, but it is not a universal limit. Current mortgage lenders offer higher multiples to applicants who meet their criteria.
Can I borrow 5 times my salary for a mortgage?
Yes. A number of lenders offer mortgages at five times income. Approval depends on affordability, your deposit, existing commitments, credit profile and the lender’s individual criteria.
Can I borrow 5.5 times my salary?
Potentially. Several mainstream lenders currently offer up to 5.5 times income for qualifying applicants, including some first-time buyers who meet the lender’s income and LTV requirements.
Can I borrow 6 times my salary?
Yes, certain lenders currently offer up to six times income. These higher multiples have additional eligibility requirements and are not available to every mortgage applicant.
What is the highest mortgage income multiple?
There is no single maximum across the UK mortgage market. Some mainstream lender criteria currently extend beyond six times income in particular circumstances, while specialist and private lenders may use different approaches.
Is 4.5 times salary a legal maximum?
No. Mortgages at 4.5 times income or above are classed as high-LTI lending for regulatory purposes, but 4.5 times income is not an individual legal borrowing cap.
Does a joint mortgage use both salaries?
Usually yes. A lender can use the eligible income of both applicants when calculating the joint LTI, although it may not accept every type of income in full.
Can self-employed people get mortgages at 5 times income or more?
Yes. Self-employed status does not automatically prevent higher-LTI borrowing. The lender must be satisfied with the income evidence, affordability and its other lending criteria.
Does a bigger deposit mean I can borrow more times my salary?
Sometimes. Some lenders offer higher maximum LTIs at lower LTVs, but there is no universal deposit threshold. Your affordability and other criteria still determine the final mortgage amount.
Do buy-to-let mortgages use income multiples?
Buy-to-let lenders usually focus primarily on the property’s expected rental income and an interest coverage calculation. Personal income can still be relevant depending on the lender and mortgage type.
