Borrow Against What You Have. Buy What You Want. Keep Both.

Most sophisticated investors face the same constraint when they consider adding a UK property asset to their portfolio. The capital required sits at a level where the only obvious move is to sell something else to fund it. Liquidate a position, redeploy the proceeds, start again. That trade-off has stopped more conversations than any regulatory barrier or market timing concern. What is less well understood is that for investors who hold a substantial portfolio with an international private bank, there is another path. One that does not require choosing between what you already have and what you want to own next.

What product finance actually is

How it works · what it is not

Product finance is a lending facility offered by international private banks against a client’s existing investment portfolio. The bank extends credit using that portfolio as collateral. The borrower receives liquidity, deploys it into a chosen asset, and keeps the underlying portfolio intact and earning.

It is not a mortgage. It is not a bridging loan. It is not a product specific to property. What makes it relevant to UK property investment is that it solves a specific problem that mortgages and bridging loans cannot: it allows an internationally mobile investor who is ineligible for UK mortgage to access a UK asset at scale, without liquidating the portfolio that funds their broader financial life.

The collateral is the portfolio, not the property. In a conventional mortgage, the lender takes security over the asset being purchased. In product finance, the lender takes security over a portion of the borrower’s investment holdings. Crucially, only the portion needed to support the facility is pledged. To obtain an £800k facility at a typical LTV of 65%, approximately £1.23M of the portfolio needs to be pledged. The remainder stays free and available for rebalancing or future use. The UK property is acquired through a Special Purpose Vehicle owned by the investor. They own the asset outright and carry the debt in full.

In product finance, interest accrues on the ledger rather than being debited automatically. The investor chooses to service it from the rental income generated by the UK asset. If the deal is structured correctly, the rental yield comfortably covers the interest cost, leaving a surplus in the account. The loan does not require a fixed repayment schedule in the way a mortgage does. It is managed against a loan-to-value threshold set by the bank against the portfolio. As long as the portfolio stays above that floor, the facility remains open. There is no fixed end date. The investor can continue, refinance, or repay when the asset is sold.

How the structure works

The flow of capital · who controls what

29k’s role is to identify and manage the UK property asset: acquisition, legal setup, property management, tenant relations, and quarterly reporting. On the finance side, we work with partner banks that offer product finance facilities and can make introductions where needed. The facility itself is negotiated and managed directly between the investor and their bank.

How it differs from a mortgage

Four structural differences · not just terminology

Structural differences apply across all product finance arrangements. Individual terms vary by bank, client relationship, and portfolio composition.

Model assumptions

The structural differences above are what make product finance worth considering. But the question a sophisticated investor will ask is a sharper one: what does this actually mean for my balance sheet after ten years? The table and chart below model both paths from an identical starting position. Every assumption is stated explicitly. The figures are conservative by design.

The debt question

Why most investors are cautious · when caution is right · when it is not

Most sophisticated investors arrive at this conversation with a deep-seated aversion to debt. That instinct is not irrational. It is shaped by watching how debt has destroyed wealth at every level. For most investors the rule is: if you can avoid borrowing, avoid it. That rule holds in most contexts. It does not hold universally. The question is not whether debt is good or bad. It is whether, in a specific set of circumstances, borrowing creates more value than it costs. Three conditions need to align for the answer to be yes.

The most common version of debt risk: the lender calling the loan, the borrower unable to repay, the forced sale at the wrong moment. This applies to poorly structured borrowing against volatile collateral with no reliable income stream. Product finance against a stable institutional portfolio, serviced by contractual rental income from a quality UK asset, is a fundamentally different risk profile. The risk is specific, and can be assessed.

Who this is for

The self-identification test · and who should wait

Product finance is not the right starting point for most investors. Before you use leverage to amplify a strategy, you need to have tested the strategy itself. The investor this article is written for has already done that. They have been in a UK property syndicate , seen the rental income arrive, and seen how the asset is managed. They are asking a different question now: not whether to invest in UK property, but whether to do more, and how.

Eligibility is determined by the lending bank based on the investor’s full profile and domicile. This is not a complete list of eligibility conditions.

Product finance is not exclusively a private syndicate tool. A co-ownership investor contributing £150,000 can borrow that amount against their portfolio rather than deploying cash. In practice we reserve this for investors who already have experience on both sides of the arrangement.

Control, not ownership, is the principle

What the investor owns · what they delegate · where decisions sit

In this structure the investor controls the SPV and the bank relationship, and decides the pace of any repayment within the bank’s thresholds. 29k manages the execution: acquisition, tenancy, quarterly distributions. The investor sets the strategy. We deliver it.

The bank relationship is the investor’s own. 29k is not a party to the finance agreement. Where an investor does not already have a relationship with a bank that offers this facility, we can make introductions. Terms, approval, and management of the facility remain between the investor and the bank throughout.

What comes next in this series

Conclusion · the deeper questions this article does not answer

One question follows naturally from the numbers shown above. The choice of borrowing currency is itself a decision with material consequences. GBP, CHF, USD, and EUR each carry different costs, and the spread between that cost and the rental yield is what determines whether the structure creates value. That will be the subject of the next article in this series.

The five conditions that make product finance viable

Important notice

Capital is at risk. The value of property and the income it produces can fall as well as rise, and an investor may get back less than they put in. Past performance and the market data referenced here are not a reliable indicator of future results, and nothing in this article is a forecast.

This article is for informational purposes only. It is not investment advice, tax advice, legal advice, or financial advice of any kind. Nothing in this article constitutes a recommendation, solicitation, or offer to buy, sell, or hold any asset or investment product.

Yield figures, return comparisons, illustrative models, and scenario outputs presented in this article are indicative only. They do not represent guaranteed, assured, or projected returns. One size does not fit all: what is appropriate for one investor may not be appropriate for another, depending on domicile, tax residence, family structure, asset profile, risk appetite, and investment objectives.

International property investment and leveraged financing structures involve complex legal, tax, and regulatory considerations that differ significantly by jurisdiction. Before making any investment decision, seek independent advice from qualified legal, tax, financial, and investment professional advisers in your own jurisdiction and in the jurisdiction of the target asset. Nothing in this article should be relied upon as a substitute for advice from your own professional advisers. Capital is at risk.
