Clients with Complex Cases – Specialist Lending Solutions. Not every borrower fits a standard profile, and that’s where expert advice makes all the difference. From self-employed business owners to high-net-worth individuals and foreign nationals, complex mortgage cases require tailored strategies and access to specialist lenders. This guide outlines the most common types of complex cases and how experienced brokers can navigate them to secure successful outcomes.
Common Types of Complex Mortgage Cases
The evolving nature of work, income structures, and life circumstances means that many borrowers no longer meet the rigid criteria of high-street lenders. Here’s a breakdown of the most common complex scenarios we help advisers support:
Complex or Irregular Income
Clients with non-traditional income often face rejection from mainstream lenders. Examples include:
-
Self-employed and business owners: Those with variable profits, reliance on investor funding, or income structured via dividends, retained earnings, or LLP partnerships.
-
Multiple income sources: Borrowers juggling PAYE income with revenue from ventures like a holiday let, part-time consultancy, or a kennel business.
-
Professionals with fluctuating pay: Barristers, freelancers, or lecturers on fixed-term contracts—earning well, but unpredictably.
These clients benefit from specialist mortgage brokers who can package their case with future earning potential and supporting documents beyond standard SA302s.
High-Net-Worth (HNW) Individuals
Many HNW clients are asset-rich but cash-poor, with their wealth tied up in:
-
Stocks and shares
-
Investment portfolios
-
Carried interest
-
Property equity
Despite low declared salaries, these individuals may qualify for tailored high-value mortgages from private banks or specialist lenders. For brokers seeking enhanced options, our Specialist Mortgage Network for Advisers offers access to underwriters experienced in HNW case structuring.
Adverse Credit History
Borrowers with credit blemishes are more common than you’d think:
-
Historic defaults or CCJs
-
Missed payments due to illness, redundancy, or HMRC issues
-
Overlooked utility or mobile bills impacting credit scores
Many lenders will instantly decline these cases, but manual underwriting lenders can offer competitive solutions when cases are clearly explained with supporting context.
Foreign Nationals & Expats
Whether you’re dealing with a UK expat returning home or a non-EU national with a visa, these clients are often blocked by lenders due to:
-
Limited or no UK credit footprint
-
Unfamiliar income documentation
-
Visa restrictions or temporary residency status
Working with specialist mortgage lenders who accept global income proof and understand expat requirements is key. Newly qualified advisers can also access this lender network through structured support.
Property-Related Complexities
Some mortgage challenges stem not from the client, but from the property itself:
-
Mixed-use properties (e.g. residential with attached commercial space like a shop or dog kennel)
-
Specialist property types are considered low-saleability by mainstream lenders
-
Significant modifications (e.g. merging two flats) that may breach existing mortgage terms
These cases require brokers with access to lenders that assess based on real value and usage, rather than automated property tags.
Life Events & Other Circumstances
Unpredictable events often create unique lending needs:
-
Divorce or separation: Including cases involving spousal maintenance, joint mortgages, or property transfers
-
Shared ownership arrangements
-
Mortgage prisoners: Clients stuck with legacy lenders post-2008 with no viable remortgage options, despite clean payment records
These cases demand a holistic financial overview, not just a credit score and salary check.
Navigating the Mortgage Process for Complex Clients
Conventional application routes don’t work for complex borrowers. Here’s what successful outcomes typically involve:
Engage a Specialist Broker
Specialist advisers understand how to position a complex case with the right narrative. They work directly with decision-makers at non-high-street lenders, presenting a full picture—not just data points. Our Why Join a Mortgage Network article explores how the right support makes these cases not only possible but profitable for advisers.
Work with Specialist Lenders
Manual underwriting is often the difference between rejection and approval. Lenders that consider personal circumstances, tax-efficiency strategies, or property uniqueness offer more flexible criteria, ideal for complex clients.
Compile Strong Documentation
Expect to go beyond standard payslips or tax returns. Depending on the case, brokers may need:
-
Future earnings letters from LLPs
-
Asset breakdowns from investment accounts
-
Divorce agreements or maintenance schedules
-
Explanatory letters for missed payments
This full-picture approach helps underwriters understand the human story behind the numbers.
Lending Landscape: Why Complexity is the New Normal
Post-pandemic income patterns, stricter stress testing, and the FCA’s Consumer Duty regime have created a mortgage climate where standardisation no longer fits all. Leading mortgage networks now use AI-powered tools to:
-
Scan case files for missing documentation
-
Predict lender match based on income structure
-
Flag early compliance risks
At Connect, we’re constantly evolving our technology and partnerships to help brokers keep up with this complexity and turn it into opportunity.

Frequently Asked Questions – Clients with Complex Cases
Can self-employed clients get a mortgage?
Yes, self-employed clients can get a mortgage, though they may need to provide more extensive documentation such as SA302s, business accounts, or accountant projections. Specialist lenders assess income more flexibly than mainstream banks.
How do lenders view multiple income streams?
Specialist lenders can consider multiple income sources such as salary, rental income, or side businesses when properly documented. A broker can help present the full financial picture clearly.
Can clients with adverse credit still get approved?
Yes. Even with defaults, CCJs, or missed payments, clients can often secure a mortgage through lenders who use manual underwriting and assess the full context of a borrower’s credit history.
Are there mortgage options for expats or foreign nationals?
Absolutely. Some lenders offer tailored solutions for UK expats and foreign nationals, even with limited UK credit history. Visa type, income source, and residency status are all considered.
What is a complex property case?
Complex properties include mixed-use buildings, heavily modified homes, or those with limited resale appeal. These cases often require niche lenders willing to evaluate beyond standard criteria.
Why use a specialist mortgage broker for complex cases?
Specialist brokers have access to non-high-street lenders and know how to present a holistic case. They also stay up to date with evolving criteria and FCA guidelines, improving approval chances.
