How Does a Property Bond Work?

Most explanations of property bonds stop at "you lend money and get interest back", which is true but not especially useful once you're actually deciding whether to invest. The parts that matter most, particularly what secures your money and what happens if the issuer can't pay, tend to get skipped over. This article goes through the process in order, from the point you first consider investing through to what happens at the end of the term, or if things go wrong along the way.

Step one: checking you're eligible to invest

Before you can even be shown most property bond opportunities, UK rules generally require you to certify that you fall into a category the FCA considers appropriate for speculative illiquid securities. In practice that usually means qualifying as a self-certified sophisticated investor or a certified high net worth investor. This isn't a box-ticking formality designed to slow you down; it exists because these products have caused real, well-documented losses for people who didn't fully grasp what they were buying.

Step two: due diligence before you commit

Once you're looking at a specific bond, the useful work starts before you sign anything. That includes reading the issuer's filed accounts at Companies House, checking whether the company or its directors have a track record with previous, completed projects, and understanding exactly what the money will be used for. It's also worth checking the loan-to-value ratio, meaning how much is being borrowed against the property relative to its assessed value. A bond secured against an asset valued conservatively at a low loan-to-value gives bondholders more of a cushion if the property later has to be sold in a hurry than one where the loan represents nearly the full value of the asset.

Step three: signing the loan note agreement

If you decide to proceed, you'll typically complete an application and sign a loan note instrument or subscription agreement. This document sets out the amount you're lending, the interest rate, how and when interest is paid, the length of the term, and the security arrangements. It's a legal contract, not a marketing brochure, so it's worth reading the actual terms rather than relying on a summary sheet.

Step four: how security over the property actually works

This is the step that deserves the most attention, and the one most often glossed over. Security is usually granted through a charge, a legal document (often a debenture) that must be registered at Companies House, typically within 21 days of being created, to be valid against a future administrator or liquidator. There are two broad types.

Separately from fixed versus floating, there's the question of ranking between different lenders who hold a charge over the same asset. A first charge holder is paid from the proceeds of that asset's sale before anyone else. A second charge holder is only paid once the first charge has been repaid in full, and receives nothing at all if the sale proceeds don't stretch that far. Some property bonds are marketed as "secured by a first charge" when, in practice, a bank has senior debt secured against the same property and the bondholders actually rank second. The only reliable way to check this is to look at the registered charge itself, not the promotional description of it.

Step five: how and when interest is paid

Interest, sometimes called the coupon, is usually paid at fixed intervals stated in the loan note agreement: monthly, quarterly, annually, or occasionally rolled up and paid as a lump sum alongside your capital at maturity. Monthly or quarterly payments suit investors who want a regular income stream. Rolled-up interest tends to suit investors more focused on total return at the end of the term, and can sometimes attract a marginally higher headline rate since the issuer isn't making cash payments along the way.

Step six: what happens at maturity

At the end of the agreed term, assuming the issuer has the funds available, you receive your original capital back in full, along with any final interest payment due. Some issuers give you the option to roll your investment into a new bond for a further term rather than taking your capital out, sometimes at a revised rate. There's no obligation to do this, and it's worth treating a maturing bond as a fresh investment decision rather than an automatic renewal, since the issuer's circumstances, or the wider property market, may have changed since you first invested.

Step seven: what happens if the issuer can't pay

This is the scenario the security is meant to protect against, and it's where the theory and the practice can diverge sharply. If an issuer defaults, typically by missing interest payments or breaching the terms of the loan note, an administrator or receiver is usually appointed. Secured creditors, meaning bondholders with a valid, registered charge, then have a claim over the specific assets covered by that charge, ahead of unsecured creditors and ahead of the company's shareholders.

In practice, this doesn't always mean bondholders get their money back. Property sold in a distressed, time-pressured administration process often fetches less than its previously assessed value. Legal and administration costs are deducted before any distribution to creditors. And if bondholders rank behind a bank's senior charge on the same asset, the bank is repaid in full first, leaving whatever is left, if anything, for the bondholders behind it.

Blackmore Bond is a well-documented illustration of exactly this gap between marketed security and actual recovery. The company raised around £46 million from roughly 2,800 investors to fund property developments, offering interest rates of between 6.5% and 10%, before stopping payments in October 2019 and entering administration in April 2020. Administrators subsequently indicated that recovery was likely to amount to only a small fraction of the money originally invested, citing poor build quality and heavy interest costs on underlying loans as key factors. It's also worth knowing that most property bonds fall outside the Financial Services Compensation Scheme in the way a bank deposit does, so there's generally no automatic compensation route if a shortfall like this occurs.

None of this means every property bond ends this way; the majority of issuers do meet their obligations in full. But it's precisely because outcomes vary so widely that the due diligence in steps two and four matter more than the headline rate ever will. For a fuller look at rates across the market and how to judge whether a specific bond represents fair compensation for its risk, see UK property bond rates, and for the wider picture of how property bonds compare to other investments, our hub article on property bonds in the UK and our comparison piece on property investment bonds explained are both worth reading alongside this one. If you're still getting to grips with the basic terminology, what are property bonds is the right starting point.

Once you understand the mechanics, the next practical step is usually to look at specific, live opportunities rather than the asset class in the abstract, which you can do using our comparison tool.
