A senior professional approaching retirement wanted to purchase a £950,000 second residential property while preserving as much of their long-term investment portfolio as possible. Although they held substantial assets within ISAs and pensions, their preference was to avoid unnecessary liquidation and secure an interest-only mortgage structured around future retirement plans. Working closely with the client, Steve Verrell arranged a solution that achieved the required borrowing while maintaining flexibility and protecting long-term wealth.

For many affluent borrowers, the challenge is not whether they can afford a property purchase, but how to structure the finance efficiently. This is particularly relevant when securing a mortgage later in life, where retirement planning, investment preservation and lender affordability models all become critical factors.

This type of scenario is increasingly common as investors and professionals seek to acquire additional properties without disrupting carefully constructed investment strategies. Many borrowers search for solutions around obtaining a mortgage after age 55, securing an interest-only mortgage before retirement, or borrowing against earned income while retaining investment assets.

When Significant Assets Don't Automatically Solve The Mortgage Challenge

At first glance, the case appeared straightforward.

The client had enjoyed a long and stable professional career spanning almost three decades, earning a substantial salary and maintaining an excellent credit profile. They also held a substantial sum within a self-managed Stocks and Shares ISA alongside pension assets held within a SIPP.

Despite this strong financial position, traditional mortgage underwriting can become more complex once borrowers move closer to retirement age.

Many lenders focus heavily on how a mortgage will be repaid beyond retirement, even where substantial assets exist. Others impose maximum age restrictions or require evidence of future retirement income that comfortably supports the proposed borrowing.

The client's objective was to purchase a second residential property valued at £950,000. While they had sufficient investment assets available to fund a significant proportion of the purchase, they wanted to avoid unnecessarily reducing their ISA holdings, which had been built over many years and formed an important component of their long-term financial strategy.

Rather than liquidating more investments than necessary, the objective was to secure a mortgage that balanced affordability, wealth preservation and retirement planning.

Why Traditional Approaches Were Not Necessarily Optimal

A conventional repayment mortgage was considered but quickly proved less attractive.

Although the client's income could support borrowing, a repayment structure over a relatively short term would significantly increase monthly commitments. This would reduce flexibility and potentially force unnecessary withdrawals from investment assets over time.

Furthermore, many mainstream lenders can struggle to assess the wider financial picture when dealing with borrowers who are asset-rich but seeking to structure borrowing efficiently rather than maximise affordability.

Traditional lenders often struggle to look beyond simple income multiples and standard retirement assumptions. In cases involving substantial investment portfolios, sophisticated retirement planning or wealth preservation objectives, a more nuanced underwriting approach is often required.

The client had identified their current main residence as a clear repayment vehicle. With significant equity available within the property, the proposed strategy was for the eventual sale of that residence to clear the outstanding mortgage balance.

This created a legitimate and credible repayment strategy that aligned with the client's wider retirement objectives.

Structuring The Finance Around Long-Term Wealth Preservation

Working closely with the client, Steve Verrell explored lenders willing to assess the case based primarily on earned income while also understanding the strength of the client's wider financial position.

A key consideration was whether the mortgage could be approved without requiring the client to draw further funds from their ISA or pension arrangements.

Following discussions with suitable lenders, a solution was identified offering a five-year fixed-rate interest-only mortgage over a twelve-year term.

Importantly, the lender was able to assess affordability using the client's earned income alone while accepting the proposed repayment strategy based on the future sale of the main residence.

This approach achieved several objectives simultaneously.

First, it reduced the amount of capital that needed to be withdrawn from the ISA, allowing the investment portfolio to remain substantially intact and continue benefiting from potential future growth.

Second, the interest-only structure kept monthly payments significantly lower than a comparable capital repayment arrangement.

Third, the twelve-year term aligned comfortably with the client's intended retirement plans, providing a clear pathway towards eventual debt repayment.

The solution also included the flexibility to make substantial annual overpayments should the client decide to reduce the balance more aggressively in future.

Balancing Mortgage Borrowing Against Investment Assets

One of the more interesting aspects of the case was the trade-off between mortgage borrowing and asset utilisation.

Some borrowers assume that having substantial investment assets automatically means they should avoid borrowing altogether. However, this is not always the most efficient outcome.

Specialist lenders are able to recognise situations where maintaining investment exposure may be financially advantageous compared to liquidating assets unnecessarily.

In this case, preserving ISA investments allowed the client to retain a diversified investment strategy while simultaneously achieving their property acquisition objectives.

Alternative structures were also explored with lenders capable of taking a more holistic view of the client's asset base. These lenders could potentially support higher borrowing levels if required by incorporating wider asset holdings into their assessment process.

While this additional borrowing capacity was ultimately unnecessary, understanding these options provided valuable flexibility and demonstrated the importance of exploring the whole market rather than relying solely on mainstream lending criteria.

The principles involved are often relevant across other areas of property finance, including complex income structures, later-life borrowing strategies and high-net-worth mortgage applications where assets play a significant role in overall affordability assessments.

Protecting Income Alongside Property Ownership

The property purchase also prompted a broader discussion around financial resilience.

The client had accumulated considerable wealth but held relatively modest liquid cash reserves outside their investment accounts. This created an important consideration around income protection.

While many individuals focus exclusively on life cover, the reality is that the inability to work due to illness or injury can often create a more immediate financial challenge.

An income protection solution was therefore recommended to provide a tax-free monthly benefit should illness or injury prevent the client from working.

The recommendation was structured to complement the mortgage commitment and broader lifestyle costs, ensuring that both the existing residence and newly acquired property could remain financially sustainable even during a prolonged absence from work.

Key Takeaways

What made this case successful was not simply the client's strong financial position but how that position was presented and assessed. While many lenders would focus primarily on age and retirement considerations, the chosen lender recognised the strength of the client's earned income, substantial equity position and credible repayment strategy.

Borrowers approaching retirement should understand that significant investment assets do not automatically eliminate mortgage challenges. Different lenders assess affordability, retirement income and repayment vehicles in very different ways. The ability to structure borrowing around existing wealth rather than forcing unnecessary asset liquidation can create significantly better long-term outcomes.



Specialist advice becomes particularly valuable where substantial assets, retirement planning considerations or interest-only borrowing requirements are involved. Understanding how lenders interpret these factors can often be the difference between an acceptable solution and an optimal one.
