Introduction: Beyond Conventional Lending
I’ve dedicated the last 20 years of my life to arranging large mortgages for hundreds of successful individuals. One thing has become abundantly clear: when you’re dealing with substantial borrowing requirements, conventional approaches simply don’t work. High-net-worth individuals require a specialist approach that acknowledges their unique circumstances and complex financial profiles.
With over £4.2 billion in financing arranged throughout my career, I’ve developed an intimate understanding of what it takes to secure exceptional terms on large mortgage facilities – even achieving 100% loan-to-value on transactions exceeding £10 million.
When you’re looking to arrange a large mortgage, you need to understand that you are special, you are unique, and your circumstances require a completely bespoke approach. Traditional lenders may not offer the flexibility needed to accommodate significant mortgage amounts, making specialized advice essential.

The Nuanced Financial Landscape for High-Net-Worth Individuals
Working with high-net-worth individuals means understanding financial profiles that often don’t align with standard High Street lending criteria.
Your circumstances likely include multiple income streams, international assets, and complex business structures that traditional lenders struggle to evaluate properly. The rigid frameworks that serve mass-market lending simply aren’t designed for the financial complexity that comes with substantial wealth.
From my experience working with clients regularly featured in the Financial Times, Bloomberg, and Forbes, I’ve learned that high-net-worth borrowers typically have:
- Diverse income sources across multiple jurisdictions
- Complex remuneration structures including equity, carried interest, and deferred compensation
- Substantial assets held in various vehicles (trusts, offshore structures, investment portfolios)
- Irregular income patterns that don’t fit conventional affordability assessments
- International properties and business interests
For lending purposes, high-net-worth individuals are typically defined as those with income exceeding £300,000 or assets over £3 million. This classification is important because it allows banks to apply different regulatory approaches, enabling more flexible lending decisions.
Why Bespoke Solutions are Essential for Large Mortgages

When you’re seeking substantial mortgage facilities, you need completely bespoke solutions tailored to your unique financial situation. Whether you’re a celebrity, billionaire entrepreneur, or successful business leader, borrowing makes financial sense when you can remain fully invested in higher-yielding opportunities while accessing cost-effective leverage.
Consider this simple calculation: If your investments generate 10-20% returns annually, while mortgage finance costs approximately 5%, remaining fully invested while borrowing strategically creates significant financial advantage. This is why the most financially astute high-net-worth individuals maintain optimal leverage on their property assets.
A personalized solution focused on your unique circumstances will ensure that your loan structure aligns with your overall borrowing objectives. For instance, we recently structured financing for a client with significant cryptocurrency holdings who was purchasing a £15 million London property. By working with specialist lenders who understood digital assets, we secured 75% financing without requiring liquidation of his crypto portfolio – preserving his position in a rapidly appreciating asset class.
Understanding Loan Structures and Flexibility
What many don’t realize is that loan structures can be infinitely flexible at the high-net-worth level. It’s entirely possible to secure 100% loan-to-value financing when you understand how to leverage your broader balance sheet effectively.
As purchase prices increase from £1 million to £3 million to £5 million and beyond, traditional loan-to-value parameters typically decrease from 95% to 90% to 85% to 70%. However, successful entrepreneurs often don’t want to liquidate investments to meet these larger deposit requirements.
This is where creative structuring becomes vital. For example, you might have investments that can be custodied alongside the property security, providing additional collateral that enables higher loan-to-values. The more liquid these assets are, the higher the potential leverage – cash might support 95-100% LTV, while investment portfolios or bonds offer substantial lending values as well.
Remember that from a bank’s capital adequacy perspective, the higher the loan-to-value, the higher the margin for the debt. But when you provide additional security in other assets, you can negotiate more favorable terms while maintaining your desired leverage.

Private Banks vs High Street Lenders – The Critical Difference
As mortgage amounts increase beyond £5-10 million, High Street lenders simply fall away – not because they don’t want your business, but because their rigid lending criteria cannot accommodate the complexity you bring.
While they offer a range of mortgage products, their standardized processes and policies rarely flex for unique circumstances.
Private banks, in contrast, consider your entire financial position, including investments and international assets. This holistic assessment enables lending decisions based on your comprehensive financial strength rather than standardized metrics. They understand the needs of uber-wealthy individuals and specialize in considering diverse income streams, dividends, and international earnings.
For example, some clients I’ve helped have secured £100 million revolving credit facilities covering multiple assets – from jets and yachts to properties across various countries.
Private banks have the ability to underwrite individual assets and asset classes to provide comprehensive financing solutions that no High Street lender could contemplate.

The difference becomes particularly apparent when we look at how credit history is evaluated. While High Street lenders rely heavily on credit scores, private banks are more concerned with your balance sheet, wealth creation journey, and the sustainability of your financial position. Many successful entrepreneurs have experienced setbacks along the way – what matters is the overall trajectory and current financial strength.
The Importance of Professional Advisors
If banks can get away with being lazy – and no disrespect to my banking partners – they will. You might be exceptionally successful and knowledgeable in your field, but presenting a credit application for a complex, large mortgage facility requires specialized expertise.
Working with a professional advisor can transform your borrowing terms. If a bank initially offers a margin of 2%, the right advisor might negotiate this down to 1.5% by strategically presenting additional security or highlighting aspects of your financial profile that reduce risk. On a £10 million mortgage, this half-percent improvement saves £50,000 annually.
I’ve spent over 20 years developing relationships with high-net-worth private bankers and specialist lending teams that understand complicated circumstances. These trusted partnerships, built on successfully delivering over £4.2 billion of financing, enable me to present complex situations effectively – whether for royal family members from the Middle East or billionaire clients with global business interests.
Leveraging Your Complete Asset Portfolio
Successful high-net-worth individuals typically have substantial collateral beyond just the property they’re financing – investment portfolios, valuable collectibles, other real estate, perhaps even jets or yachts. Every single asset can be leveraged depending on your appetite for risk and longer-term objectives.
Lenders will assess your overall balance sheet and the liquidity of each item to determine potential lending values. For instance:
- Cash and cash equivalents: 90-100% lending value
- Marketable securities: 50-80% depending on volatility
- Residential real estate: 60-80% depending on location and quality
- Commercial real estate: 50-75% depending on tenancy and location
- Art, wine, collectibles: 30-50% with proper authentication and insurance
- Jets and yachts: 50-70% for newer models with good maintenance records
In a high-profile case featured in the Financial Times’ “How the Super-Rich Buy Their Homes,” we secured a 90% loan-to-value on a £50 million purchase. How? By working with a bank willing to consider the client’s substantial stock portfolio as additional security. This wasn’t a “gentleman’s agreement” but a carefully structured facility that protected both the client’s investment strategy and the bank’s risk position.
International Income and Cross-Border Considerations
Many global entrepreneurial individuals have multiple income streams in multiple currencies from multiple countries. Traditional income verification methods simply don’t capture this financial picture.
Specialist lenders often consider international income and understand this in great detail. They can look at offshore income, inheritance, trust income, and complex international business revenues in ways that traditional lenders cannot.
For instance, we recently arranged financing for a client with primary income from a Singapore-based tech company, investment returns from a Swiss portfolio, rental income from properties in France and Spain, and distributions from a Cayman Islands trust. By working with a private bank with a global footprint, we secured a £25 million facility at competitive rates, despite the complexity of the income sources.
The key is proper preparation – documenting each income stream appropriately, providing clear explanations of the sustainability of each source, and working with advisors who understand international wealth structures.
Preparing Detailed Financial Documentation
When you work with an expert, you’ll prepare detailed financial documentation that demonstrates transparency and stability. This includes comprehensive asset portfolio details, income records from various sources, and clear explanations of complex structures.
The preparation of these materials is an art form in itself – showing stability, sustainability, and clarity in what can often be extremely complex financial arrangements. Your team of tax advisors, family office professionals, and accountants should collaborate closely with your mortgage specialist to present the most favorable picture.
Remember that proper preparation, a detailed credit summary application, and expert negotiation are essential to achieving a win-win outcome for both you as the borrower and the bank as the lender.

Frequently Asked Questions
Typically, individuals with net income exceeding £300,000 or assets worth over £3 million are considered high-net-worth borrowers for lending purposes. This classification is important because it allows banks to apply different regulatory approaches, enabling more flexible lending decisions than would be possible for standard borrowers.
Private banks offer personalized, bespoke, and flexible lending solutions, often considering your overall financial situation rather than just standard income metrics. They can accommodate complex income structures, international assets, and unique circumstances. High Street lenders, in contrast, adhere to standardized processes and policies, making them suitable for more straightforward situations but limiting for complex high-value arrangements.
Almost anything of value can potentially serve as collateral for large mortgages. This includes traditional assets like investment portfolios, commercial and residential real estate, as well as alternative assets like art collections, wine portfolios, classic cars, jets, and yachts. Each asset class has different lending values based on liquidity, volatility, and marketability.
Yes, specialist lenders often consider international income from multiple sources and jurisdictions. Many global entrepreneurs have diverse income streams in various currencies, and private banks with international presence are well-equipped to evaluate and incorporate these into lending decisions.
Higher loan-to-value ratios can be achieved by providing additional security beyond the property itself. This might include investment portfolios, other property assets, or high-value collectibles. The structure of the facility, the liquidity of the additional assets, and the relationship with the lender all play crucial roles in maximizing your borrowing capacity while maintaining favorable terms.
While credit history is considered, it’s viewed differently for high-net-worth borrowers compared to standard mortgage applicants. Private banks understand that successful entrepreneurs often take risks and may have experienced setbacks. What matters more is your current financial strength, the source and sustainability of your wealth, and your overall asset position. Proper explanation and contextualization of past credit issues are key to addressing any concerns.
Specialist advisors bring deep market knowledge, established relationships with decision-makers at lending institutions, and expertise in presenting complex financial situations optimally. They understand how to structure applications to highlight strengths and mitigate concerns, often securing more favorable terms than direct applications. The difference can be substantial – typically 0.5-1% in margin improvement, representing significant savings on large facilities.
