What Does My Income Really Mean for Mortgage Affordability in Scotland and London?

Homes are getting MORE affordable, according to these three key measures |  This is Money

When people ask how much can I borrow for a mortgage, what they are really asking is:

How will lenders interpret my income?

This is where most confusion and missed opportunities occur.

Mortgage affordability is not based on income alone. Lenders assess how income is earned, how stable it appears, and how reliably it can be maintained over time. As a result, two borrowers earning the same amount can receive very different mortgage offers.

Pelican Finance Limited regularly supports buyers across Scotland and London who were told “not enough” by banks, only to secure a mortgage by presenting their income correctly and choosing the right lender.

Income Is Not Just a Number, It Is a Structure

Lenders do not only ask how much you earn. They ask how reliable that income is.

Affordability is influenced by:

• How income is paid
• How consistent it appears
• How long it has been earned
• Whether it is increasing or declining

This is why income structure matters as much as income level.

PAYE Employees: More Nuanced Than Many Expect

For salaried employees, lenders typically assess:

• Basic salary, which is always counted
• Overtime, usually averaged over three to twelve months
• Bonuses, often capped or averaged
• Commission, which requires history and consistency

In London, some lenders apply stricter affordability stress tests due to higher assumed living costs.
In Scotland, lenders are often more flexible, particularly outside major cities.

This difference highlights why mortgage affordability in Scotland versus London should be assessed carefully rather than assumed.

Self Employed Borrowers: Where Affordability Is Often Underestimated

Self employed applicants frequently lose borrowing power because income is assessed too narrowly.

Common issues include:

• Only net profit being considered
• Retained company profits being ignored
• Dividends not structured clearly

Pelican Finance works with lenders who may consider:

• Salary plus dividends
• Company retained profits
• One or two years of accounts, depending on lender criteria

Correctly presenting self employed income can significantly improve affordability without increasing risk. This is especially relevant for self employed mortgage applicants in Scotland and London.

Contractors: Income Can Be Stronger Than PAYE

Contractors are often misunderstood by high street banks.

Specialist lenders may assess income using:

• Day rate multiplied by contracted days
• Annualised contract value
• Multiple contracts if income is consistent

This approach can dramatically improve affordability, particularly for contractors working in London or remotely across the UK.

Multiple Income Streams: Can They Be Combined?

Yes, but only with the right lender.

Additional income may include:

• Second jobs
• Freelance income
• Rental income
• Maintenance payments

Each income type has different acceptance rules. Presenting these correctly is key to maximising borrowing while remaining compliant.

This is where independent mortgage advice becomes important.

Scotland Specific Affordability Considerations

In Scotland:

• Mortgage offers are based on Home Report valuations
• Buyers often offer above valuation
• Borrowing is capped at valuation, not offer price

This means income may support the loan, but deposit planning becomes critical. You can read more about this in our guide on how much deposit you need in Glasgow and Edinburgh.

London Specific Affordability Considerations

In London:

• Lenders assume higher living costs
• Affordability stress testing is stricter
• Joint applications are more common

Income alone rarely tells the full story. Lender selection and income structure matter just as much.

Why Affordability Calculators Often Fall Short

Online calculators often:

• Use conservative assumptions
• Ignore specialist lenders
• Cannot assess complex income structures

They are useful as a guide, but they are not a decision. Many buyers underestimate what they can borrow because calculators cannot reflect real lender criteria.

How Pelican Finance Maximises Borrowing Responsibly

Pelican Finance supports borrowers by:

• Matching income type to lender criteria
• Structuring applications strategically
• Avoiding unnecessary declines
• Planning affordability before any application is submitted

This approach helps buyers move forward with confidence rather than guesswork.
