For ultra-high-net-worth families, wealth is rarely idle. It is held intentionally across prime real estate, long-term investment portfolios, private businesses, trusts, and intergenerational structures designed to preserve capital rather than optimise short-term liquidity.

Historically, many UHNW families deliberately avoided leverage. Mortgage-free prime residences in London, Paris, Monaco, and the South of France were seen as a marker of financial security and independence. Liquidity needs were met through asset disposals, internal family loans, or portfolio rebalancing.

In 2025, this thinking has shifted.

Rising opportunity costs, more complex intergenerational planning, and increasingly sophisticated private lending markets mean that holding large volumes of unencumbered assets is no longer always optimal. Forced asset sales are now widely viewed as inefficient, tax-exposed, and strategically disruptive.

Asset-backed lending has therefore evolved from a niche solution into a core balance sheet tool for UHNW families and family offices seeking liquidity without compromising long-term ownership or control.

Willow Private Finance works directly with UHNW families, family offices, private banks, and specialist lenders to structure discreet, low-leverage borrowing solutions that unlock capital while preserving strategic optionality.

Market Context in 2025: Why Asset-Backed Lending Has Accelerated

The private lending landscape has matured significantly over the past decade. While mainstream banks have tightened affordability-led criteria, private banks and specialist lenders have moved decisively in the opposite direction for high-quality borrowers.

For UHNW clients, lending decisions are no longer driven primarily by earned income. Instead, lenders focus on balance sheet strength, asset quality, diversification, and long-term wealth sustainability.

This evolution mirrors trends explored in High Net Worth Mortgages in 2025: What Lenders Look for Beyond Income, where private banks increasingly prioritise asset resilience and liquidity over traditional affordability metrics.

At the same time, macroeconomic conditions have reinforced the case for borrowing rather than selling. Prime assets have remained resilient, but transaction volumes have become more sensitive to timing, pricing, and geopolitical uncertainty. Selling under pressure rarely achieves optimal outcomes.

Asset-backed lending allows UHNW families to remain patient owners while still accessing capital when required.

What Asset-Backed Lending Actually Means for UHNW Families

Asset-backed lending is often misunderstood as a simple mortgage alternative. In reality, it represents a fundamentally different underwriting philosophy.

Rather than assessing borrowing capacity through income multiples, lenders evaluate the borrower’s entire financial ecosystem. This includes:

• The depth and quality of property holdings
• The liquidity and volatility of investment portfolios
• Jurisdictional and legal structures
• Existing leverage and contingent liabilities
• Governance and long-term planning objectives

In many cases, facilities are structured against multiple assets simultaneously, creating portfolio-level lending solutions rather than single-asset mortgages.

Unlocking Liquidity Without Selling Prime Assets

One of the most compelling reasons UHNW families use asset-backed lending is to avoid forced or suboptimal sales.

Prime assets are often held for generational reasons. Trophy homes, core investment properties, or long-held family assets may carry emotional, strategic, or tax significance that makes selling undesirable.

However, liquidity demands still arise. These may include:

• Capital calls or private investment opportunities
  
• Business expansion or acquisitions
  
• Family distributions or generational restructuring
  
• Tax liabilities or estate planning events
  
• Strategic diversification outside core holdings

Asset-backed lending provides liquidity while preserving ownership, allowing families to remain aligned with their long-term vision.

How Private Banks and Specialist Lenders Assess Risk

For UHNW borrowers, risk assessment is far more nuanced than for mainstream clients.

Lenders begin with asset analysis. Prime residential property in global cities remains highly favoured, particularly where demand is international and supply constrained. Investment-grade commercial property, high-quality mixed-use assets, and stabilised income-producing portfolios are also attractive.

Liquidity matters. Lenders assess how quickly assets could be realised in adverse conditions, not just headline valuations. Conservative loan-to-value ratios provide comfort, particularly where assets are held internationally.

Borrower structure is equally important. Trusts, holding companies, and family investment vehicles must be clearly documented and legally robust. Ambiguity around ownership or control can limit lender appetite, a challenge often addressed through careful structuring.

Ultimately, lenders are not seeking leverage. They are seeking downside protection and long-term alignment.

Cross-Border Asset Portfolios and Jurisdictional Complexity

Most UHNW families hold assets across multiple countries. This introduces layers of legal, tax, and enforcement complexity that mainstream lenders are rarely equipped to handle.

Cross-border asset-backed lending requires careful coordination. Jurisdictional differences in property law, security enforcement, currency exposure, and tax treatment must all be considered.

In many cases, facilities are structured through private banks or specialist lenders with international balance sheets, allowing assets in different jurisdictions to be aggregated within a single borrowing framework.

Willow Private Finance regularly structures cross-border solutions involving UK, European, and offshore assets, working alongside legal and tax advisers to ensure lending aligns with wider family office objectives rather than creating future friction.

Managing Risk: Why Conservative Structures Matter

While asset-backed lending offers flexibility, it is not without risk.

Interest rate exposure, refinancing risk, and margin calls on investment-backed facilities must all be actively managed. UHNW families typically prioritise stability over aggressive pricing, favouring structures with conservative covenants and flexibility over headline rate reductions.

Fixed or capped rate options, longer facility tenors, and clear exit strategies are often more valuable than marginal cost savings.

Independent advice is critical. Private banks may incentivise leverage to support internal investment strategies, whereas an independent broker focuses on alignment, not product sales.

Asset-Backed Lending as a Family Office Tool

For family offices, asset-backed lending has become an operational tool rather than a financing product.

Liquidity lines can smooth cash flow, bridge timing mismatches, and support investment mandates without constant asset rotation. When integrated into a wider balance sheet strategy, borrowing enhances optionality rather than increasing risk.
