A long-established business owner and property investor approached Willow Private Finance seeking funding to acquire the flat adjacent to his existing home. The opportunity was unusual: purchasing a neighbouring lower-ground-floor apartment within the same prestigious building and gradually integrating it into a wider residential footprint over the coming years.

The client required a minimum of £500,000 to facilitate both the acquisition and planned refurbishment works. Despite owning substantial unencumbered property assets and having significant equity across his portfolio, traditional funding routes presented several challenges. By restructuring existing borrowing and leveraging property wealth strategically, a tailored solution was engineered that provided the liquidity required while maintaining flexibility for future plans.

This type of scenario is increasingly common among affluent property owners looking to unlock value from existing assets rather than disposing of investments or disrupting longer-term wealth strategies.

A Valuable Opportunity With Complex Funding Requirements

The client owned a prime residential property valued at approximately £1.1 million with no mortgage outstanding. Adjacent to the property was a flat available through a private sale at an agreed purchase price of £450,000.

The vision was not simply to acquire an investment property. Instead, the client intended to undertake a phased refurbishment programme over approximately three years before effectively expanding the enjoyment and utility of the existing residence while maintaining separate legal titles.

The proposed works were expected to cost around £150,000, with the combined project anticipated to generate significant value uplift. Following completion, the adjacent flat was expected to be worth approximately £750,000 independently, while the client's existing residence was projected to increase in value to between £1.4 million and £1.5 million.

However, the property sat within a High-Rise Residential Building (HRB) environment requiring Building Safety Regulator involvement, introducing additional complexity and potential delays. Traditional lenders often struggle to accommodate projects involving evolving building control requirements, particularly where future plans extend beyond straightforward refurbishment.

Why Standard Lending Was Not the Obvious Solution

At first glance, the client's position appeared exceptionally strong.

He owned multiple properties, including:

• A valuable London residence with substantial equity.
• An HMO property generating rental income.
• An unencumbered buy-to-let investment property.
• Significant liquid savings.

However, lender assessment was more nuanced.

Although the client had been employed within the same business since the 1990s and held a long-standing directorship, his personal salary and dividend income appeared modest when viewed in isolation. Like many owner-managed businesses, personal drawings did not fully reflect overall financial strength.

Traditional high-street underwriting models frequently focus on declared salary and dividends, which can create challenges when assessing borrowers whose wealth is predominantly asset-based rather than income-based.

Specialist lenders are able to assess broader financial circumstances, including property wealth, rental income streams, business ownership, liquidity, and future income potential.

In this case, the client's gross earnings history, property income, company ownership, and asset position all contributed to a significantly stronger overall profile than would have been evident from personal income alone.

Engineering the Right Funding Structure

Working closely with the client, Elizabeth Powell analysed multiple routes to raise the required capital.

A straightforward remortgage of the residential property alone would not generate sufficient proceeds to fund both acquisition and refurbishment costs. Equally, introducing unnecessary borrowing against all available assets would have reduced flexibility and potentially increased long-term costs.

Several options were considered, including specialist development finance, bridging finance strategies, and conventional remortgage solutions.

While bridging finance can often be appropriate for property acquisition and refurbishment projects, the client's relatively long three-year implementation timeline meant that longer-term debt structures offered a more cost-effective solution.

The strategy ultimately focused on extracting capital efficiently from existing assets while preserving future refinancing opportunities.

The residential property was refinanced on an interest-only basis, generating additional capital. Simultaneously, the unencumbered buy-to-let property was leveraged to raise an additional funds.

This dual-property approach allowed the client to release more than £500,000 without requiring complex development finance structures or short-term bridging facilities.

The interest-only structure was particularly important. By avoiding capital repayment obligations during the project period, cash flow remained available for refurbishment works and future investment opportunities.

Balancing Leverage, Flexibility and Future Growth

One of the key considerations involved balancing borrowing levels against future objectives.

The client intended to sell his primary residence in approximately three years, creating a natural repayment strategy for any debt secured against the property.

Increasing leverage further may have generated additional liquidity immediately, but it would also have reduced flexibility if project costs changed or market conditions shifted.

Likewise, extending borrowing terms beyond the planned retirement horizon could have introduced unnecessary complexity.

The selected structure provided sufficient funding while maintaining prudent loan-to-value ratios across the portfolio.

Importantly, it also preserved future options should the client later wish to explore alternative strategies such as further property acquisition, portfolio restructuring, or specialist refinancing.

These considerations frequently arise in complex income structures where property wealth significantly exceeds declared income levels. Similar challenges are often seen in expat mortgage scenarios and other cases involving substantial asset bases but unconventional earnings profiles.

The Outcome

The final structure delivered over £500,000 of accessible capital through a combination of residential and buy-to-let refinancing.

This enabled the client to:

• Acquire the adjoining flat through the private sale arrangement.
• Fund the planned refurbishment programme.
• Retain ownership of multiple investment assets.
• Preserve substantial liquidity reserves.
• Maintain interest-only borrowing aligned with long-term objectives.
• Position the combined project for significant future value growth.

By utilising existing equity strategically rather than relying on short-term finance, the client secured a solution that aligned with both current requirements and future plans.

Key Takeaways

What made this case possible was not simply the amount of property equity available but how that equity was structured and assessed. Traditional lenders often struggle to evaluate clients whose wealth is spread across business interests, investment properties, and retained assets rather than straightforward employment income. Specialist lenders are able to look beyond salary figures and assess the wider financial picture.

For borrowers considering property expansion projects, adjacent property acquisitions, or complex refurbishment plans, the optimal solution is not always the lender offering the highest loan amount. Careful consideration must be given to future exit strategies, project timelines, leverage levels, and flexibility requirements. In many cases, strategic refinancing can achieve similar outcomes to bridging finance while reducing overall funding costs.



Cases such as this demonstrate the importance of specialist advice when significant assets, multiple properties, and long-term planning objectives intersect.
