Family Investment Companies (FICs) have become one of the most widely used wealth-structuring vehicles among high-net-worth families in the UK and internationally. Their ability to combine corporate control with family-level succession planning makes them uniquely attractive for property ownership—particularly in portfolios designed to grow across generations. In recent years, families have increasingly used FICs to acquire UK residential and investment property, both as part of long-term wealth strategies and as efficient structures for managing substantial assets.

However, while FICs offer many strategic advantages, obtaining a mortgage within a company of this type requires navigating a detailed, specialist underwriting process. Lenders in 2025 are more sophisticated than ever in their approach to corporate structures. They understand the growing use of FICs but require clarity around ownership, governance, liquidity, and long-term intentions. Many borrowers assume that because a FIC is a UK company, the lending process will be simple. In reality, underwriting a FIC can resemble underwriting a trust or offshore SPV, requiring deeper analysis than a conventional limited company.

Willow Private Finance works with many families who structure their assets through FICs or similar vehicles. These cases often intersect with the issues faced by international buyers, high-net-worth individuals, and clients with non-traditional income—topics explored in our guides on high-net-worth asset-based borrowing and international buyer mortgage requirements. The principles are the same: lenders must understand the real economic power behind the structure.

This guide outlines how lenders assess FICs in 2025, what documentation they expect, how private banks differ from mainstream lenders, and the strategies families can use to secure favourable mortgage terms.

Why Families Use FICs for Property Ownership in 2025

FICs allow families to retain control over assets while passing growth to future generations. Parents often act as directors and control voting rights, while children or future heirs receive shares that participate in capital growth. For property ownership, this can be highly efficient. It allows rental income, capital appreciation, and reinvestment decisions to sit within the company. It also enables families to consolidate multiple properties under one structure.

Another strategic motivation is the ability to separate personal wealth from corporate investment activity. For families holding substantial assets, it can be cleaner to transact within a FIC than in individual names. This can simplify record-keeping, wealth management, and long-term planning.

Importantly, many FICs also hold investment portfolios alongside property. In these cases, families often use portfolio pledges to enhance borrowing power—a strategy explored in our article on using investment portfolios to buy UK property. When structured well, these assets can dramatically increase lender appetite.

Despite these advantages, lenders still view FICs as complex entities. They must trace ownership, understand voting rights, assess decision-making authority, and confirm that those providing guarantees or liquidity are aligned with the company’s borrowing.

How Lenders Assess FICs in 2025

Lenders approach FICs with a blend of corporate underwriting and private-bank style wealth assessment. Their primary objective is to understand who ultimately stands behind the company and how long-term liquidity will service the mortgage.

The first area lenders review is ownership. A FIC often includes multiple family members, including minor children or future heirs. Lenders must understand who holds growth shares, who holds controlling shares, and which individuals are in a position to provide guarantees. If minors hold shares, lenders need assurance that borrowing decisions remain with adult directors.

The second key area is governance. Lenders review the company’s articles to ensure directors have authority to borrow and grant security against property. If authority is missing or unclear, responsible directors may need to approve amendments or provide minutes confirming their ability to proceed.

Next, lenders examine the economic substance of the company. They need to understand whether the FIC is simply a holding vehicle, whether it receives rental income, or whether it holds investment portfolios or other assets that could support borrowing. In many cases, private banks treat the wealth of the family as more meaningful than corporate balance-sheet strength. For this reason, they often request personal guarantees or additional liquidity evidence from key family members.

Finally, lenders review the long-term intention for the property. A FIC used for a growing property portfolio is viewed differently from one acquiring a single home for later transfer to family members. Clarity of purpose increases lender confidence.

Differences Between Mainstream Lenders and Private Banks

Mainstream lenders typically treat FICs similarly to limited companies used for buy-to-let properties, but this approach has limitations. They rely heavily on rental-income calculations and often restrict lending where ownership includes minors, trusts, or cross-generational structures. Their underwriting frameworks are too rigid to accommodate the flexibility and complexity required for many FIC-based applications.

Private banks, by contrast, specialise in understanding wealth-planning structures. They recognise that rental income alone does not reflect the true financial strength of the family. They assess personal liquidity, investment portfolios, and global assets. This allows them to lend far more generously to FICs, especially where substantial family wealth sits outside the company.

Private banks also offer repayment flexibility. Interest-only mortgages, longer-term facilities, or loans supported by portfolio pledges are common. The underwriting approach used here is similar to that applied to complex offshore structures, as explored in our guide on how private banks lend to offshore entities. In many cases, the same private banks that lend to offshore companies will also lend to FICs.

For families seeking high-value lending, private banks are usually the most suitable route.

Documentation Lenders Require for FIC Mortgages

Although FICs are UK-registered companies, their documentation requirements resemble those of complex structures. Lenders typically request the full suite of company documents, director appointments, shareholder registers, and evidence of voting rights. Where trusts or offshore elements are involved, lenders may also request trust deeds, letters of wishes, or details of professional trustees.

Personal identification is required for all shareholders and directors, even where their involvement is minimal. Lenders also request minutes authorising borrowing, especially for acquisitions above £1 million.

If the FIC holds investment portfolios, lenders usually request a full breakdown of assets, liquidity, and performance. For private-bank mortgages, this information can also be used to support enhanced borrowing or improved pricing.

Families must also provide source-of-wealth evidence for the individuals who capitalised the FIC. This step is essential for regulatory compliance and is not optional.

Challenges FICs Face When Securing Mortgages

One of the biggest challenges for FICs is the amount of documentation required. Even well-organised companies must coordinate shareholder approvals, director resolutions, company records, and supporting wealth documents. If trusts or offshore shareholders are involved, the process becomes more involved.

Another challenge is lender appetite. Not all lenders accept FICs, and those that do often treat them cautiously. Some lenders apply stricter stress-testing models or require personal guarantees from every shareholder, even where minors are excluded from decision-making.

Tax considerations also impact lender appetite. Lenders want assurance that the FIC structure has a legitimate family-planning purpose and is not used primarily for tax reduction. As always, families should seek independent tax advice.

Finally, timing is a recurring issue. FIC mortgages often take longer than personal applications because lenders must complete additional company checks and review corporate records. Early preparation is essential.

Smart Strategies for FIC Borrowers in 2025

Families using FICs can significantly improve lending outcomes by preparing early and structuring applications in a lender-friendly way. One effective strategy is ensuring that company articles explicitly allow borrowing, granting security, and entering mortgage contracts. Many FICs need minor amendments before they can legally take out a mortgage, and addressing this early avoids delays.

Another smart approach is consolidating liquidity within the FIC or demonstrating clear access to family wealth. When lenders see that the company has substantial backing, they are more willing to offer favourable terms.

Families with investment portfolios may also use asset pledges to enhance borrowing power. As explored in our guide on investment-backed property finance, pledging certain assets can significantly improve underwriting outcomes.

Finally, appointing professional advisors—such as accountants, company secretaries, or family-office managers—helps ensure documents are produced efficiently and with the clarity lenders expect.

How FIC Mortgages Typically Work - Hypothetical Scenario

A representative example involves a family holding several rental properties within a FIC. The parents act as directors and hold voting rights, while adult children hold growth shares. The family plans to acquire a new £1.5–£3 million property to expand the portfolio.

A private bank will assess the rental strength of the proposed property, but more importantly, it will evaluate family wealth held outside the FIC. Investment portfolios, business income, and global assets shape the lending decision far more than rental yield. The bank may offer an interest-only mortgage supported by a modest personal guarantee from each director and an asset pledge covering part of the exposure.

Another example involves a FIC acquiring a London home intended for future family use. Even if the property is not let out, private banks will lend based on the family’s wealth, treating the FIC as a long-term holding entity rather than an income-producing business.

These scenarios show why mainstream lenders struggle and private banks succeed in this space.

Outlook for 2025 and Beyond

FIC-based property ownership is set to remain strong throughout 2025 and 2026. Lenders anticipate continued growth in family wealth planning and increased demand for structured ownership vehicles. Private banks, in particular, will play an expanding role, offering bespoke lending solutions that align with intergenerational planning, investment strategies, and long-term wealth objectives.

We expect private banks to deepen their appetite for high-value FIC lending, particularly where investment portfolios or diversified global wealth support the borrowing. Specialist lenders will also continue refining their models for corporate property ownership, giving families more options than ever.
