A mid-career architect with a strong asset base sought to acquire the flat adjacent to their primary residence through a private sale, with plans to refurbish and integrate the space over time. Despite significant property wealth, the case was constrained by modest declared income, complex asset positioning, and building-specific challenges. Working closely with the client, Elizabeth Powell structured a £500,000 funding solution that balanced leverage, flexibility, and future exit strategy, unlocking a projected £750,000 GDV uplift and long-term value creation.
Early in the process, it became clear this was not a standard mortgage scenario. This type of case often falls under searches such as structuring finance for property refurbishment with complex income or raising capital against unencumbered property for development purposes.
Navigating Complexity Beneath Strong Asset Wealth
At first glance, the client’s position appeared robust. An unencumbered main residence, alongside additional investment properties, including an HMO and a debt-free buy-to-let, suggested substantial security. However, traditional lenders rarely assess cases purely on asset strength.
The core constraint lay in income structuring. Although the client’s business generated consistent gross income annually, their declared salary and dividends were significantly lower. This is a common challenge among directors of limited companies, where tax efficiency often results in income profiles that fall outside standard affordability models.
Traditional lenders often struggle to reconcile this disparity. Automated underwriting systems typically prioritise PAYE-style income or averaged dividends, often ignoring retained profits or broader asset context. In this case, that resulted in a lending ceiling of approximately £260,000, well below the required £500,000.
Compounding this, the property being acquired introduced additional complexity. The flat sat within a high-rise building classified under High-Risk Building (HRB) regulations, requiring Building Safety Regulator (BSR) oversight. This significantly lengthens approval timelines and introduces additional compliance layers, factors many mainstream lenders are reluctant to engage with, particularly where refurbishment is involved.
This type of scenario is increasingly common in London and other urban markets, where building regulations, leasehold structures, and refurbishment ambitions intersect.
Why Conventional Approaches Fell Short
Several traditional routes were assessed but ultimately discounted.
A straightforward residential remortgage, even at maximum loan-to-value, could not generate sufficient capital due to income constraints.
Extending the term to improve affordability was considered, but the client’s preference to align borrowing with retirement planning limited this option.
Buy-to-let refinancing was also explored across the client’s investment properties. While rental income was strong, lenders apply strict stress-testing metrics, particularly on interest-only lending. This capped borrowing levels and limited flexibility, especially when combined with existing debt on the HMO property.
Additionally, attempting to fund both the purchase and refurbishment through a single long-term mortgage would have introduced further friction.
Many lenders avoid funding properties requiring significant works, particularly within regulated buildings.
In essence, each conventional route addressed part of the requirement, but none could deliver the full £500,000 needed with sufficient speed and flexibility.
A Strategic Shift Toward Asset-Led Structuring
Recognising these constraints, Elizabeth Powell reframed the case away from income-led borrowing and toward an asset-based strategy.
Specialist lenders are able to assess risk differently, particularly where strong security exists. In this case, the client’s unencumbered residential property provided a compelling foundation for short-term leverage. Rather than forcing the case into a rigid affordability model, the focus shifted to:
- Asset quality and location
- Loan-to-value positioning
- Clear exit strategy via future sale or refinance
- The uplift potential from refurbishment
The client’s plan, to acquire, refurbish, and ultimately expand their living space before selling within three years, provided a credible and defined exit route. The projected GDV on the new unit, alongside the uplift of the primary residence, further strengthened the case.
This aligns closely with broader bridging finance strategies, where short-term funding enables value creation ahead of refinancing or sale.
Structuring the Right Blend of Funding
The final structure combined elements of residential refinancing and investment lending to achieve the required capital stack.
A residential remortgage was secured on an interest-only basis, providing a core layer of funding at a competitive rate. While this alone did not meet the full requirement, it established a cost-effective foundation.
Alongside this, a buy-to-let refinance was arranged against the client’s investment property. This leveraged rental income while maintaining interest-only flexibility, ensuring affordability remained manageable.
The combined structure allowed the client to access just over £500,000, meeting both acquisition and refurbishment requirements.
Critically, this approach balanced several trade-offs.
Higher leverage increased overall borrowing costs, but preserved liquidity and avoided the need to liquidate assets or disrupt existing investments.
Opting for interest-only lending reduced monthly commitments, aligning with the client’s cash flow and long-term strategy. Meanwhile, fixed-rate elements provided short-term certainty while retaining flexibility for the planned exit within three years.
Specialist lenders are able to accommodate this type of layered structure, particularly where the borrower demonstrates a clear strategy and strong asset backing.
Outcome and Strategic Impact
With funding secured, the client was able to proceed with the private acquisition, often a time-sensitive scenario where delayed financing can result in missed opportunities.
The refurbishment phase, supported by approximately £150,000 in planned works, will gradually enhance both the acquired property and the adjoining residence. The ability to generate interim rental income further supports the holding strategy.
Over the medium term, the integrated property is expected to deliver significant capital appreciation, with a projected combined value increase well beyond the initial investment.
This approach also positions the client for future refinancing opportunities, particularly once works are completed and income streams stabilise, an important consideration in complex income structures and evolving portfolio strategies.
Key Takeaways
This case demonstrates how strong asset positions can unlock opportunities that income-based lending alone cannot support. Traditional lenders often struggle to accommodate borrowers with efficient income structuring, particularly where declared earnings do not reflect underlying financial strength.
By shifting the focus toward asset value, loan-to-value ratios, and a clearly defined exit strategy, specialist lenders were able to assess the case more holistically. The ability to layer funding across multiple properties, rather than relying on a single facility, proved critical in achieving the required capital.
For clients in similar situations, particularly those with property portfolios, complex income, or refurbishment ambitions, the key is understanding how lenders interpret risk differently. Structuring finance is not simply about securing the lowest rate; it is about aligning the funding strategy with the broader objective, balancing cost, flexibility, and long-term outcomes.
Specialist advice becomes particularly valuable in these scenarios, where conventional routes fall short and a more nuanced approach is required.
Frequently Asked Questions
Can I get a mortgage if my declared income is low but I own substantial property assets?
Yes. While many mainstream lenders focus heavily on salary and dividend income, specialist lenders can often take a broader view. They may place greater emphasis on your property portfolio, available equity, loan-to-value ratio, and overall financial position, particularly where there is a clear repayment strategy.
Can I borrow money to buy the neighbouring flat and combine it with my existing home?
Potentially, yes. Purchasing an adjoining property to create a larger residence is a recognised strategy, although it often requires specialist finance. Lenders will consider factors such as the property's configuration, planning requirements, building regulations, and how you intend to refinance or repay the borrowing once the project is complete.
Why would a mainstream lender decline an application despite significant property wealth?
Traditional lenders primarily assess affordability using declared income and standard underwriting models. If your income is structured through a limited company, relies on retained profits, or is lower for tax efficiency purposes, they may offer significantly less than your available assets might otherwise support.
Can I use equity from multiple properties to fund a refurbishment project?
Yes. In many cases, borrowing can be structured across more than one property to achieve the required level of funding. This may involve a combination of residential remortgaging, buy-to-let refinancing, or specialist lending solutions depending on your objectives and existing portfolio.
What is asset-based lending and how does it differ from traditional mortgage underwriting?
Asset-based lending places greater emphasis on the quality and value of the security rather than relying solely on earned income. Specialist lenders often assess the strength of your assets, the proposed loan-to-value ratio, and your exit strategy, making it suitable for borrowers with complex financial profiles.
Can I obtain finance for a property located in a High-Risk Building (HRB)?
Yes, although lending options may be more limited. Buildings subject to Building Safety Regulator requirements often involve additional legal and technical checks, meaning many mainstream lenders are cautious. Specialist lenders are generally more experienced in assessing these types of transactions.
Is interest-only borrowing suitable for refurbishment or value-add projects?
For many borrowers, interest-only finance can reduce monthly outgoings during the refurbishment period, preserving cash flow while improvements are completed. Whether it is appropriate depends on your long-term plans and the strength of your proposed repayment strategy.
Can limited company directors borrow more if retained profits are considered?
Some specialist lenders are willing to assess retained company profits alongside salary and dividends when evaluating affordability. This can significantly improve borrowing capacity for business owners whose income is structured for tax efficiency.
How important is an exit strategy when arranging specialist property finance?
It is one of the most important aspects of the application. Lenders want to understand exactly how the borrowing will be repaid, whether through refinancing, property sale, asset disposal, or another defined strategy. A credible exit plan can substantially strengthen a complex application.
When should I use a specialist mortgage broker instead of approaching lenders directly?
If your circumstances involve complex income, multiple properties, refurbishment works, private acquisitions, high-value borrowing, or non-standard security, specialist advice can often identify lending solutions unavailable through high street banks. Structuring the finance correctly from the outset can improve both the likelihood of approval and the long-term outcome.

Important Notice
This case study is provided for illustrative purposes only and does not constitute financial or legal advice. The details have been anonymised and certain elements may have been simplified to protect client confidentiality.
Property finance arrangements involving multiple properties, refurbishment works, or complex income structures are assessed on a case-by-case basis. Outcomes will vary depending on individual circumstances, lender criteria, and market conditions at the time of application.
The availability of mortgage and bridging finance products, including interest rates, loan-to-value limits, and underwriting requirements, can change at short notice. Not all lenders will consider properties requiring significant works, high-rise buildings subject to Building Safety Regulator (BSR) approval, or applicants with non-standard income profiles.
Bridging finance is typically a short-term funding solution and may carry higher costs than traditional mortgages. It is essential that borrowers have a clear and credible exit strategy, such as refinancing or sale, before entering into any agreement.
Interest-only mortgages require a suitable repayment strategy to be in place to repay the capital at the end of the term. Failure to maintain payments may result in repossession of the secured property.
Tax treatment, including the ownership of property in personal names or through limited companies, and any potential capital gains or income tax implications, will depend on individual circumstances and may change over time. You should seek independent advice from a qualified accountant or tax adviser before proceeding.
Your home may be repossessed if you do not keep up repayments on your mortgage.
