A liquidity event—whether a business exit, a major share sale, a bonus windfall, or RSUs vesting—is often a life-changing financial milestone. For many, it coincides with a desire to upgrade property, invest in prime real estate or diversify wealth into UK residential assets. Yet in 2025, borrowers are frequently surprised to learn that having significant liquidity does not automatically translate into an easy mortgage process.
Despite the strength of your balance sheet post-event, lenders want to understand far more than the sum that now sits in your account. They want to know the source, timing and sustainability of the wealth. They want clarity on tax treatment, future income, long-term affordability and whether the event represents a one-off or part of a broader pattern of wealth creation. In many ways, underwriting after a liquidity event is more detailed than underwriting before it.
Willow Private Finance works with clients at every stage of liquidity creation—from founders who have recently exited a business, to tech executives with newly vested equity, to partners in investment firms receiving carried-interest distributions. Many of these clients encounter challenges similar to those covered in our guides on

This guide explains how banks treat liquidity events in 2025, how to prepare your profile for underwriting and how Willow Private Finance positions clients to maximise borrowing for prime and super-prime property.
The 2025 Lending Climate for Post-Liquidity Borrowers
The 2025 market remains cautious. While interest rates have stabilised compared with previous years, lenders are operating under intense regulatory scrutiny. They must show that mortgages are affordable not just today, but over the long term—even when borrowers possess significant assets. This creates a unique environment for individuals who have recently experienced a liquidity event.
Banks are enthusiastic about lending to wealthy clients, but they are equally focused on assessing how income and outgoings will look once the transaction settles. A liquidity event may present immediate strength but raises questions about future earnings. If the borrower has sold a business or realised an investment, the lender wants to know what replaces that income stream going forward. If the liquidity event was tied to one-off equity vesting, lenders want clarity on future vesting potential or the borrower’s remuneration structure.
This is why private banks tend to dominate this segment. They can take wealth into account, not just annual income. Mainstream lenders, by contrast, continue to rely heavily on income models that can undervalue newly liquid wealth unless presented correctly.
How Lenders View Liquidity Events
A liquidity event means different things depending on who you are—a founder selling equity, a director taking a distribution, an executive with RSUs vesting, an investor exiting a position, or a partner receiving a carried-interest payout. To a lender, however, the event represents both an opportunity and a set of questions.
A lender will want to know the nature of the liquidity. Share sales are treated differently from profit distributions. Vesting events are treated differently from capital exits. Bonus windfalls are assessed differently from asset disposals. Each category contains its own underwriting nuances, documentation requirements and risk considerations.
Banks also want to understand the sustainability of the liquidity. If the liquidity event represents the culmination of a one-off exit, lenders must be assured that the borrower can meet future repayments through other income streams or through available liquid wealth. If the event is part of a recurring compensation structure—as is often the case with executives in technology or private equity—lenders may take a more generous interpretation.
Equally important is the tax treatment of the liquidity. Lenders need evidence that liabilities are accounted for and that the net proceeds genuinely reflect wealth available for deposit or servicing the loan. This is particularly relevant for large capital gains, cross-border structures or equity awards subject to complex tax implications.
Why a Liquidity Event Does Not Guarantee Maximum Borrowing
Clients are often surprised when large cash balances do not automatically equate to high loan-to-value approvals. In 2025, lenders are more cautious about borrowed affordability, even when the borrower could seemingly buy the property outright.
This is because lender regulation is based on responsible lending principles. Even if the borrower has several million pounds in the bank, lenders must demonstrate that the borrower can sustain the mortgage without eroding capital too quickly. They cannot assume the borrower will use their entire liquidity to fund future payments.
Where private banks differ is in their interpretation. They may approve an interest-only mortgage based on wealth, liquidity or investment portfolios, rather than conventional income. This approach works particularly well when the liquidity event is substantial, and the borrower has a wider wealth ecosystem—investments, cash reserves, recurring income or diversified assets.
Mainstream lenders simply do not have this flexibility. Their models rely on income, not wealth, which is why liquidity-event borrowers often find themselves routed toward private banking solutions.
How Banks Assess Income After a Liquidity Event
Income becomes a central question in post-liquidity underwriting. If the liquidity event resulted from selling a business, lenders need clarity on whether the borrower continues to receive salary, consultancy income or dividends from the company. If not, lenders want to understand the new source of income replacing business remuneration.
Executives who receive liquidity from vested RSUs or bonuses must show the structure of future awards. A one-off vesting event may not count as a recurring income source, but consistent multi-year vesting patterns provide reassurance.
Investors who sell assets must demonstrate how future investment income—dividends, interest or capital gains—will support affordability. Private banks are comfortable assessing portfolio-based income, but mainstream lenders usually require taxed, recurring income.
Ultimately, lenders want to ensure that the liquidity event does not represent the peak of financial strength before a potential decline. They need evidence of sustainability.
Using Liquidity to Strengthen Your Mortgage Profile
Large liquidity events offer several advantages when structured correctly. They allow for higher deposits, opening the door to better rates, reduced loan-to-value ratios and increased lender appetite. They also support interest-only borrowing—particularly in private banking—where lenders rely on wealth rather than salary.
Liquidity also helps with wealth-based lending. Private banks often provide mortgages supported by investment portfolios, allowing borrowers to keep capital invested while unlocking leverage at competitive rates. This approach is covered in depth in our article on
How Wealthy Buyers Raise Cash for UK Property Without Selling Investments.
For high-value prime or super-prime purchases, large liquidity events position borrowers strongly for bespoke underwriting, customised loan structures and, in some cases, reduced income documentation requirements.
Challenges Borrowers Face After a Liquidity Event
Despite strong financial standing, borrowers often encounter unexpected friction. Lenders may treat the liquidity event as a one-time occurrence, which limits the amount they will include in affordability. If the borrower’s income has reduced post-exit, lenders may focus more on future sustainability than on current wealth.
Another challenge is documentary complexity. Lenders expect clear evidence of the liquidity event—completion statements, share sale agreements, vesting summaries, tax calculations and proof of funds. Incomplete documentation slows underwriting and may limit borrowing potential.
Borrowers with cross-border structures face additional hurdles. Wealth generated overseas must be evidenced, taxed and traceable. Differences in documentation standards between countries can delay applications unless prepared correctly.
Finally, timing matters. If the liquidity event occurs shortly before the mortgage application, lenders may want additional reassurance that the wealth is fully settled, finalised and not subject to clawback or pending liabilities.
Hypothetical Scenario
Consider a founder who sells shares in their company for several million pounds. A high-street lender may still base their decision on the founder’s new post-exit income, not on the value of the liquidity. This dramatically lowers potential borrowing.
A specialist lender, with more flexible underwriting, may accept a higher level of wealth as part of the assessment but still rely heavily on predictable income streams.
A private bank, by contrast, may approve an interest-only facility based primarily on the liquidity itself, supported by the borrower’s broader wealth and investment strategy. This can lead to significantly higher borrowing power and more favourable terms, illustrating why post-liquidity borrowers typically benefit from private banking routes.
Outlook for 2025 and Beyond
Liquidity-event borrowing is likely to become even more aligned with private banking in the coming years. As compensation structures evolve and more individuals create wealth through business exits, equity rewards and investment realisations, lenders will continue refining their criteria.
Private banks are expected to increase their offering for post-liquidity borrowers, emphasising relationship value, long-term investment potential and wealth-based lending structures. Meanwhile, mainstream lenders may remain conservative, maintaining strict affordability models aligned primarily to income.
Borrowers who prepare early, gather documentation and structure their assets effectively will be in the strongest position to secure high-value lending throughout 2025 and beyond.

Frequently Asked Questions
Q1: Will lenders accept cash from a liquidity event as proof of affordability?
A: Lenders accept liquidity as wealth but do not automatically treat it as income. Private banks are generally more flexible, especially with large deposits or investment portfolios.
Q2: How long after a liquidity event should I wait before applying for a mortgage?
A: Borrowers can apply immediately, but lenders may require full documentation. Timing is less important than clarity of source, tax position and sustainability.
Q3: Do private banks offer better terms for post-liquidity borrowers?
A: Often yes. Private banks focus on total wealth rather than income alone and may offer interest-only or wealth-backed lending structures.
Q4: Can I use shares instead of cash when applying for a mortgage?
A: Some private banks allow lending against investment portfolios, including shares, but most lenders require liquidity for deposits and fees.
Q5: What documentation do lenders need after a liquidity event?
A: Typically proof of funds, sale agreements, vesting statements, tax documents and evidence that the funds are fully settled and accessible.
Q6: What if my income decreases after an exit?
A: Private banks often accept reduced income when wealth is substantial. Mainstream lenders may be more restrictive.
