A fixed-income trader at a global investment bank secured a high-value residential mortgage using a remuneration structure heavily weighted toward variable bonus income. The mortgage was structured to reflect sustainable earnings rather than mechanical bonus caps.
Client Snapshot
Profession: Fixed-income trader, global investment bank
Location: London
Property Type: Residential house
Purchase Price: £2,100,000
Mortgage Amount: £1,500,000
Loan-to-Value: 71%
Income Structure: £130,000 base salary plus variable annual bonus significantly exceeding base
Employment Status: Long-standing front-office role
Context
The client was purchasing a long-term family home following several years in a front-office trading role. While overall remuneration was strong, a substantial proportion of income was delivered through an annual discretionary bonus, which varied year to year based on market conditions.
The objective was to secure a mainstream residential mortgage that reflected true earning capacity, without relying on aggressive assumptions or being constrained by rigid bonus caps that did not align with the client’s role or track record.
The Challenge
Many mortgage lenders apply restrictive approaches to bonus income, particularly where:
Base salary is materially lower than total compensation
Bonus income exceeds fixed pay
Remuneration is discretionary rather than contractual
In this case, several lenders limited usable bonus income to 50% of historic averages or capped bonus at the level of base salary, resulting in affordability figures that understated the client’s sustainable earnings.
Without careful lender selection and income presentation, borrowing capacity would have been unnecessarily restricted despite a strong employment history and consistent bonus delivery.
Lender Strategy
Lenders were assessed based on their experience with front-office trading roles and their treatment of bonus-led remuneration.
Income was structured around sustainability rather than headline volatility, supported by historic bonus evidence, employment continuity, and role profile. Affordability was modelled conservatively to align with lenders willing to look beyond simple bonus caps and apply a more contextual assessment.
Several lenders were discounted early due to inflexible bonus limits or formulaic income calculations. A lender with a pragmatic framework for assessing bonus-led income in established trading roles was selected, allowing the application to progress smoothly.

The Result
A residential mortgage of £1.5m was approved, supporting the purchase of a £2.1m home.
The structure reflected sustainable earnings rather than arbitrary bonus limits, allowing the client to proceed without relying on overly aggressive affordability assumptions.
Why This Matters for Similar Clients
Traders often assume that large or volatile bonuses will automatically limit borrowing options. In practice, lender appetite depends far more on how bonus income is assessed than on the presence of variability itself.
Where role stability and earnings sustainability can be evidenced, bonus-led income does not need to be mechanically capped or discounted.
