A professional couple in their early thirties were planning to purchase their first home together, targeting properties up to £1,000,000. One applicant already owned a mortgage-free property jointly with family members, while the other was a first-time buyer. Although both earned substantial incomes, a significant portion of their affordability depended on variable bonus earnings, creating a challenge around how lenders would assess their true borrowing capacity.

Working closely with the clients, Steve Verrell structured a solution that maximised lender appetite for professional borrowers while ensuring the proposed borrowing remained sustainable over the long term.

For borrowers researching how to secure a large residential mortgage using salary and bonus income, this case demonstrates how lender assessment methods can materially influence the outcome.

Looking Beyond Basic Salary

At first glance, the clients appeared to be in a strong position.

They had a  strong deposit, no adverse credit history, no unsecured debt commitments beyond a student loan, and strong employment records with established professional firms.

However, when purchasing property at values approaching £1 million, affordability calculations become significantly more complex than simply multiplying salary by a standard income multiple.

The female applicant earned a good basic salary and had recently started receiving performance-related bonuses. Because those bonuses had not yet been evidenced over a sufficient period, many lenders would either ignore them entirely or apply significant restrictions.

The male applicant earned a higher basic salary alongside a profit-related bonus and additional performance incentives. While these bonuses were substantial, lender treatment varies considerably. Some lenders require two or even three years of consistent bonus history before incorporating the income into affordability calculations. Others may use only a percentage of bonus earnings or average them over multiple years.

This type of scenario is increasingly common as more professionals receive compensation through performance-based remuneration rather than purely fixed salaries.

Why Lender Selection Was Critical

Traditional lenders often struggle to assess variable income consistently, particularly when bonuses form a meaningful proportion of total earnings.

The challenge was not whether the clients could afford the mortgage in practical terms. Their income and expenditure profile clearly demonstrated a strong monthly surplus.

The challenge was identifying lenders whose underwriting models could appropriately recognise the strength of the applicants' overall financial position.

Several potential approaches were considered.

• One option was to focus solely on basic salary income. While this would simplify underwriting, it would unnecessarily reduce borrowing capacity and potentially limit the range of properties available.
• Another option was to utilise lenders willing to consider recent bonus income where there was clear evidence that future earnings were likely to continue. This approach offered significantly greater flexibility but required careful lender selection and presentation.

The existing property ownership position also required consideration. Although one applicant owned a share in a mortgage-free property, this ownership structure involved family members and therefore needed to be correctly understood by the lender when assessing assets, liabilities and future housing arrangements.

Rather than relying on automated affordability models, the solution required a lender prepared to assess the broader picture.

Structuring the Finance

After reviewing the available options, the most suitable solution involved a mainstream lender offering competitive rates while maintaining flexibility around bonus income assessment.

The proposed structure was based on a capital repayment mortgage over a 37-year term, ensuring the debt would be fully repaid before the applicants' anticipated retirement age.

Three purchase scenarios were modelled to provide flexibility as property searches progressed.One thing stood out, a modest reduction in borrowing requirements can often improve both affordability and product availability.

Trade-offs were also considered between two-year and five-year fixed rates.

The two-year options provided slightly greater flexibility should rates fall in the future, while the five-year products offered longer-term payment certainty and protection from future rate increases.

Neither approach was inherently superior. The optimal choice depended upon the clients' future plans, appetite for certainty, and expectations regarding future interest rate movements.

Why the Solution Worked

The success of the case ultimately came down to how the applicants' income was assessed.

Rather than viewing bonus earnings as unreliable, the chosen lender was willing to examine the nature of the employment, the consistency of remuneration structures, and the overall strength of the applicants' careers.

Specialist lenders are able to take a more nuanced approach in certain circumstances, but in this case it was possible to remain within the mainstream lending market while still benefiting from flexible underwriting.

The lender's willingness to consider the broader income picture significantly increased available borrowing capacity and ensured that the clients could comfortably pursue properties at the upper end of their target range.

The structure also retained flexibility through permitted annual overpayments and potential portability should the clients move home in the future.

The Outcome

Following affordability assessment, the lender confirmed that the proposed borrowing levels were achievable in principle.

In fact, the applicants demonstrated sufficient affordability to support borrowing beyond the required for a £1 million purchase.

This provided confidence that their property search could proceed without concerns around financing constraints.

By carefully selecting a lender whose underwriting philosophy aligned with the clients' income profile, Steve Verrell was able to secure competitive residential mortgage options across multiple purchase scenarios while maintaining sensible long-term affordability.

Key Takeaways

What made this case successful was not simply the strength of the applicants' income. It was the ability to identify a lender that assessed that income appropriately.

Many professional borrowers assume every lender evaluates bonus income in the same way. In reality, lender criteria can differ significantly, particularly where variable remuneration forms part of total earnings.

Traditional lenders often struggle to accommodate complex income structures without extensive track records, while other lenders are prepared to take a more holistic view of future earning potential and employment stability.

For clients purchasing higher-value residential property, lender selection can be just as important as interest rate selection. Understanding how income is assessed, how affordability is calculated, and which lenders are most receptive to specific circumstances can materially improve both borrowing capacity and product availability.



This principle frequently applies across related scenarios including complex income structures, first-time buyer mortgage applications, and higher-value residential purchases where affordability calculations become increasingly sophisticated.
