How Do Lenders Calculate the Income Needed for a £150,000 Mortgage?

Most UK lenders use a loan-to-income (LTI) multiple, generally between 4× and 4.5× annual income. Some specialist lenders or specific cases may go above 4.5×, but these are less common.

Using typical LTI ranges:

• 4× income → £150,000 mortgage requires £37,500 annual income
• 4.5× income → £150,000 mortgage requires £33,333 annual income

These figures assume:

• No significant debts
• Steady employment
• Clean credit profile
• Standard mortgage terms

If you have debts, credit issues or variable income, the usable income figure may change.

4.5× income	£33,333

What If Applying Jointly?

For joint applications, lenders combine both applicants’ incomes.

Example scenarios:

• Couple earning £20,000 + £15,000 → Combined £35,000
  • May achieve £150,000 with lenders offering 4.25× or above
• Couple earning £25,000 + £25,000 → Combined £50,000
  • Typically qualifies easily within 4× income rules
• Couple earning £30,000 + £20,000 → Combined £50,000
  • Also comfortably within typical LTI limits

Joint income often improves affordability but lenders also review both credit files.

How Deposit Size Affects Income Requirements

A larger deposit can improve affordability and lender choice.

5% deposit (£7,500)

• Higher affordability scrutiny
• Limited lenders depending on credit profile

10% deposit (£15,000)

• More favourable affordability
• Broader choice of lenders

15–20% deposit (£22,500–£30,000)

• May unlock higher income multiples
• Stronger overall profile for applicants

A larger deposit does not change the required income directly, but it can allow lenders to stretch more on affordability.

Monthly Repayments on a £150,000 Mortgage (Illustrative Only)

Repayments vary with rate and term. Below are examples on a standard capital repayment basis:

25-year term

• 4% rate → ~£792/month
• 5% rate → ~£877/month
• 6% rate → ~£966/month

30-year term

• 4% rate → ~£716/month
• 5% rate → ~£805/month
• 6% rate → ~£899/month

Longer terms reduce payments but increase total interest.

Lenders consider whether your income can comfortably support these payments after analysing your spending and existing commitments.

What Else Lenders Assess Beyond Income?

1. Credit History

Lenders look at:

• Missed payments
• Defaults
• CCJs
• Credit utilisation
• Age of credit issues

Even with the right income, recent credit issues may reduce borrowing power.

---

2. Debts and Ongoing Commitments

Examples include:

• Credit cards
• Loans
• Car finance
• Student loan deductions
• Childcare or maintenance payments

These may reduce affordability.

Example:

If £300/month of commitments exist, the lender may reduce the maximum mortgage offered.

---

3. Spending Behaviour

Lenders analyse 3–6 months of bank statements to assess:

• Regular expenses
• Gambling transactions
• Excessive overdraft usage
• Subscriptions and non-essential spending

Stable, predictable spending supports affordability.

---

4. Employment Type and Income Stability

Lenders review:

• Permanent vs fixed-term contracts
• Self-employed earnings (2–3 years’ records commonly assessed)
• Bonus, overtime and commission (may only accept a percentage)

Your employment type affects how much income is considered usable.

---

Can You Get a £150,000 Mortgage on a Low Income?

This may be possible with:

• A joint application
• A larger deposit
• Low outgoings
• Lenders offering higher income multiples

Specialist lenders sometimes accept 5× or 5.5× income, but availability depends on wider criteria.

---

Examples of Who Might Qualify for a £150,000 Mortgage

Example 1: Single applicant, £35,000 salary

Likely achievable with lenders offering 4.25× or higher.

Example 2: Single applicant, £33,000 salary

Possible with lenders offering 4.5× income.

Example 3: Joint applicants earning £18,000 + £20,000

Combined £38,000 — usually within affordability.

What Documents You Need for Affordability

Lenders typically request:

• 3 months’ payslips
• P60
• 3–6 months’ bank statements
• Identification and proof of address
• Full credit report
• For self-employed: SA302s or tax calculations and accounts

These help lenders verify income and assess spending patterns.
