A professional couple wanted to purchase a Grade II listed detached home while retaining their former residence as an investment property. The purchase involved a self-employed architect, an employed applicant who had recently received a significant pay rise, an existing residential mortgage on a property now operating under a consent-to-let arrangement, and a listed building requiring light refurbishment.

Although the clients had strong incomes, a sizeable deposit and an excellent credit profile, the combination of property type, income structure and existing commitments created a lending scenario that required careful lender selection.

Working closely with the clients, Steve Verrell structured a residential mortgage solution that enabled them to acquire their long-term family home while preserving their existing investment property and maintaining flexibility for future financial planning.

This type of scenario is increasingly common as homeowners choose to retain former residences as investment assets while moving up the property ladder. Borrowers searching for a mortgage with self-employed income and a retained buy-to-let property often discover that lender treatment of existing commitments can vary significantly.

When Multiple Small Complexities Become One Large Underwriting Challenge

At first glance, the case appeared relatively straightforward.

The clients required a mortgage supported by asignificant deposit derived from savings and family assistance. Their combined income was strong, consisting of self-employed earnings from a successful architectural practice alongside a recently increased employed salary.

However, several underwriting considerations sat beneath the surface.

The property being acquired was Grade II listed, immediately narrowing the lender pool. While listed buildings are financeable, many lenders apply stricter valuation requirements due to concerns surrounding maintenance obligations, future alterations, specialist construction considerations and long-term marketability.

Alongside this, the clients already owned a property subject to an existing residential mortgage. Although the property was generating rental income under a consent-to-let arrangement, lenders would assess the treatment of this commitment differently. Some would largely offset the mortgage against rental income, while others would apply a more cautious affordability assessment.

Traditional lenders often struggle to accommodate cases where multiple policy considerations intersect. Individually, none of these factors represented a major issue. Collectively, they required careful lender positioning.

Why Lender Selection Was Critical

The self-employed element of the application required particular attention.

Mrs had traded successfully, generating profits in the latest financial year. While this demonstrated consistency and growth, lender methodologies vary considerably when assessing sole trader income.

Some lenders focus on the latest year's figures, while others average multiple years. Certain lenders may apply additional scrutiny where applicants are purchasing more expensive properties or retaining other residential assets.

At the same time, Mr had recently received a salary increase. While this strengthened affordability, not every lender would immediately use the higher figure without suitable evidence confirming the increase.

The existing property added another layer of complexity.

The former home carried an outstanding mortgage balance,  and generated rental income. Because the property was not held under a standard buy-to-let mortgage, some lenders viewed the commitment more conservatively than others.

This is similar to challenges frequently encountered in other specialist areas of lending, including complex income structures, expat mortgage scenarios and certain bridging finance strategies where lender interpretation can be just as important as the client's actual financial strength.

Understanding the Listed Property Challenge

The Grade II listed status of the property was arguably the most significant factor influencing lender choice.

Many borrowers assume that listed buildings create financing difficulties because of their age. In reality, lender concerns are typically centred around future saleability, repair obligations and valuation risk.

A listed property can be perfectly acceptable security, but lenders need confidence that any future purchaser will also be able to obtain finance. Surveyors therefore take a particularly close look at condition, maintenance requirements and any planned refurbishment works.

Because the property required light improvements, the chosen lender needed to be comfortable that the works were cosmetic in nature and would not materially affect the building's listed status or future mortgageability.

Specialist lenders are often able to take a more pragmatic view of listed properties, but even among mainstream lenders there can be substantial differences in appetite.

Structuring the Right Solution

After assessing the available options, Steve identified a lender willing to take a balanced view of the overall case.

The recommendation centred around a capital repayment mortgage over a 35-year term. This aligned with the clients' desire for certainty that the mortgage would be fully repaid before retirement while keeping monthly commitments manageable.

Two fixed-rate options were presented.

The first provided a two-year fixed rate, offering flexibility and the opportunity to review the market sooner. The second provided a five-year fixed rate, delivering longer-term payment certainty and protection from potential future rate volatility.

Interestingly, the difference in monthly cost between the two products was relatively modest. This meant the decision became less about affordability and more about the clients' attitude towards future interest rate movements and their preference for certainty versus flexibility.

The lender also allowed arrangement fees to be added to the mortgage. This was an important consideration because retaining liquidity can be particularly valuable when purchasing older or listed properties, where unforeseen expenditure can occasionally arise after completion.

Balancing Property Ambitions with Long-Term Planning

Every mortgage structure involves compromise.

The clients could have increased their deposit contribution by retaining less liquidity. Equally, they could have selected a shorter mortgage term to reduce overall interest costs.

However, both approaches would have reduced flexibility at a time when they were simultaneously managing a new home purchase and an existing investment property.

The chosen structure created an appropriate balance.

It allowed the clients to acquire the property they wanted, retain ownership of an income-producing asset, preserve a degree of financial flexibility and ensure that the mortgage would be fully repaid over time.

Importantly, it also aligned with their broader objective of building long-term property wealth while securing a family home that met their future lifestyle requirements.

The Outcome

The final recommendation enabled the clients to proceed with the purchase of their Grade II listed home while retaining their former residence as a rental investment.

Through careful lender selection and a structured approach to affordability, the application successfully addressed concerns around self-employed income, listed property considerations and the treatment of an existing mortgaged asset.

Most importantly, the solution supported the clients' wider objectives rather than forcing them into a structure driven solely by lender policy constraints.

The result was a mortgage arrangement that delivered certainty, flexibility and long-term sustainability while allowing the clients to continue building wealth through property ownership.

Key Takeaways

What made this case possible was not simply the clients' income or deposit size, but the way their overall circumstances were presented to the lender. Traditional lenders often struggle to assess cases involving listed properties, retained residences and mixed income structures through a standard underwriting lens.

By carefully selecting a lender whose criteria aligned with the clients' circumstances, Steve Verrell was able to secure a solution that recognised the strength of the overall financial position rather than focusing on isolated underwriting concerns.



For borrowers purchasing listed buildings, retaining existing properties or relying on self-employed income, lender selection can be every bit as important as interest rate selection. Specialist advice often identifies opportunities that may be missed when applications are assessed solely against generic lending criteria.
