In 2025, more borrowers than ever rely on income that fluctuates throughout the year—bonuses, dividends, carried interest, capital gains, profit shares, and investment returns. These sources can create significant wealth, but they don’t align neatly with traditional lender expectations of stable monthly income. As a result, many high-earning professionals now struggle with mortgage applications despite having substantial overall financial strength.

This challenge is especially common among entrepreneurs, directors, founders, consultants, investment professionals, and global executives whose compensation patterns don't resemble the PAYE profiles mainstream lenders are built around. Even large bonuses or repeated six-figure dividends may be discounted or ignored entirely by automated affordability models.

At Willow Private Finance, we specialise in structuring mortgages for individuals with complex or uneven income, drawing on lender relationships that understand wealth beyond monthly payslip figures. Clients in similar positions often come to us after being declined by high-street banks or receiving smaller offers than expected, only to secure significantly higher borrowing once their income is properly packaged. Many of the same principles apply to clients with irregular high earnings or those with multi-country income streams.

This guide explains how lenders assess bonuses, dividends, and capital gains in 2025—and how Willow Private Finance positions clients to achieve strong outcomes in an increasingly cautious lending landscape.

Market Context in 2025

The 2025 lending environment is shaped by higher baseline interest rates and tightened affordability rules. Regulators continue to push lenders toward robust income verification, encouraging conservative treatment of variable or non-guaranteed earnings. As a result, lenders are more cautious about what they classify as sustainable income.

High-street banks generally require stability and predictability, so they treat bonus-heavy or dividend-led profiles conservatively. Meanwhile, private banks and specialist lenders have broadened their approach, recognising that modern wealth creation often comes in large, episodic inflows instead of traditional salaries. These lenders assess the substance behind the income—ownership stakes, business profitability, historical patterns, and liquidity—rather than relying on monthly payroll figures.

The gap between mainstream and specialist lending has widened. In 2025, affluent clients with irregular income patterns increasingly require nuanced underwriting and skilled representation.

How Lenders Assess Lumpy Income

Lumpy income refers to earnings that do not arrive consistently every month. Lenders categorise the most common forms as bonuses, dividends, capital gains, and investment returns. While each source presents its own assessment challenges, lenders look for patterns and credibility rather than rigid monthly amounts.

Bonuses

Professionals in financial services, tech, consulting, and senior corporate roles often receive a small base salary supported by significant annual or semi-annual bonuses. Lenders may use:

• A multi-year average to smooth fluctuations
• The lower of the last two years if income is inconsistent
• A proportion of the bonus if the employer does not guarantee it

In 2025, banks place greater emphasis on employer confirmation letters and bonus history to justify including this income in affordability.

Dividends

Dividends are common among business owners, directors, and shareholders who choose tax-efficient remuneration structures. Lenders assess:

• The profitability of the business producing the dividends
• How sustainable the distribution pattern is
• Whether retained profits support the declared income

A strong set of company accounts is often more persuasive than the applicant’s personal tax return.

Capital Gains

Capital gains—often from investment portfolios, asset disposals, or carried interest—are less predictable but sometimes substantial. Traditional lenders hesitate to include them unless there is a history of disposals or a clear, ongoing investment strategy. Private banks are more flexible, particularly when the client holds a large, diversified portfolio or when realisation of assets is part of a broader wealth plan.

Investment or Portfolio Income

Some applicants receive irregular returns from portfolios, trust distributions, or private equity holdings. These sources require detailed documentation, usually including portfolio statements, trust reports, fund summaries, and evidence of liquidity. Lenders want to understand whether these returns are planned, sustainable, and repeatable.

Ultimately, lenders judge each income type in context. A lump-sum-driven profile supported by strong assets can be more compelling than a modest salary with no wealth behind it.

What Lenders Are Looking For

While each lender has its own policy, they share common underwriting themes.

First, they examine the consistency of income. Even if earnings are irregular, a multi-year pattern of bonuses, dividends, or gains builds a compelling case. A one-off windfall does not carry the same weight as repeated distribution activity.

Second, lenders consider the stability of the underlying source. For example, dividends backed by strong retained profits and healthy cashflow are treated more favourably than dividends extracted from a business experiencing volatility. Similarly, capital gains arising from a diversified portfolio are more reliable than gains from a highly concentrated investment.

Third, they explore liquidity. A borrower with sizeable assets but no accessible cash may appear strong on paper but weak from a risk perspective. Demonstrating access to liquidity—even if through a revolving credit facility or investment drawdown—can materially improve the application.

Finally, lenders want to understand sustainability. Underwriters ask whether the irregular income is likely to continue, whether the level is predictable enough to support long-term mortgage affordability, and whether the borrower has a credible buffer against future dips in income.

Challenges Borrowers Face

Borrowers with uneven income often underestimate how conservative mainstream lenders have become. Automated systems frequently fail to recognise the true financial strength of an individual whose compensation is concentrated into a few annual events.

One challenge is that tax returns do not always reflect reality. For example, a director who leaves profits within the company may appear to have “low income” despite substantial wealth. Similarly, executives with deferred bonuses may not have visible earnings in the year they wish to borrow.

Another issue is inadequate presentation. Private banks expect structured financial summaries, detailed breakdowns of compensation, and documentation linking corporate or investment performance to personal income. When these materials are absent, lenders often default to declining or heavily restricting borrowing.

Timing also plays a major role. Borrowers who receive income at the end of the financial year may appear to have low income in the months preceding a transaction. Without careful packaging, this creates an artificial affordability problem.

Smart Strategies That Work in 2025

Strategic preparation is one of the most powerful tools for clients with variable income. When approached correctly, lenders can be far more flexible than their published criteria suggest.

One effective strategy is presenting multi-year income evidence, showing patterns that justify including bonuses, dividends, or gains in affordability. Averaging over two or three years can significantly increase borrowing potential.

For business owners, preparing clear business accounts and management information often makes a decisive difference. A lender who sees stable profits and strong retained earnings is far more likely to include dividends—even when they fluctuate.

Another strategy involves using assets to strengthen the application. Clients with investment portfolios, unencumbered properties, or high-value holdings may benefit from wealth-based underwriting—where assets play a larger role in affordability. This approach is common among private banks and similar to the methods used in asset-led cases, as covered in our guide on borrowing using assets instead of income.

Timing adjustments also help. Planning the mortgage application around known liquidity events—bonus payments, shareholder distributions, or asset disposals—can materially improve the available lending terms.

Finally, using the right lender is often the ultimate difference. Private banks frequently take a holistic view of wealth, incorporating future bonuses, investment income, and even unrealised gains when structured properly.

Hypothetical Scenario

Many Willow clients in this category fall into two broad profiles. The first is the senior corporate or finance professional whose base salary forms only a small portion of their overall compensation. Their significant bonuses, profit shares, or deferred awards may not fit neatly into standard affordability models. When presented correctly, private banks can often lend based on a blended income model or even anticipated awards.

The second profile is the entrepreneur or company director who extracts dividends irregularly depending on business performance and tax planning. While a mainstream lender may discount this income, private banks analyse the company itself—profitability, cashflow, retained earnings, and the borrower’s ownership stake. When the numbers support it, borrowing capacity can be significantly higher than what a high-street bank would allow.

In both cases, tailored packaging and lender selection make a substantial difference to the final outcome.

Outlook for 2025 and Beyond

The trend toward flexible earning patterns is not slowing down. More buyers now receive compensation tied to business performance, investment returns, equity vesting, or variable corporate structures—making traditional salary-focused underwriting increasingly outdated.

Private banks and specialist lenders are continuing to adapt, with many introducing more sophisticated income modelling, liquidity-based assessments, and multi-year averaging tools. Over the coming years, this is likely to expand further, with underwriting shifting toward a total-wealth perspective rather than simple income stability.

For borrowers, the key point is clear: in 2025, irregular income is not a barrier to high-value borrowing—provided the case is structured professionally.
