What Are Property Bonds and How Do They Work?

A property bond is, at its core, a loan. You lend money to a company, usually one involved in property development or property investment, and in return that company promises to pay you a fixed rate of interest for an agreed period, then hand back your original capital when the term ends. The loan is typically secured against property assets, which is where the name comes from. It isn't a bond in the sense of a government gilt or a listed corporate bond you can trade on an exchange; it's closer to a private IOU dressed up in more formal legal clothing.

These products go by a few different names depending on who's issuing them: property bonds, property loan notes, secured loan notes, or sometimes just "loan notes". The mechanics are broadly similar across most of them, even where the marketing language differs. For a wider look at how property bonds fit into the alternative investment landscape as a whole, see our guide to property bonds in the UK.

How the structure actually works

Strip away the branding and a property bond is a fairly simple arrangement, even though it usually involves more parties than first appears. A property company, the issuer, wants to raise money, often to buy a site, fund a development, or refinance existing debt. Rather than borrowing solely from a bank, it issues loan notes directly to private investors. You buy a loan note for, say, £10,000, and the company uses that money, pooled with money from other investors, to fund its property activity.

In exchange, the issuer agrees to pay you interest at a fixed rate stated in the loan note documentation, usually monthly, quarterly or annually. At the end of the term, commonly somewhere between one and five years, you get your capital back in full, assuming the company can meet its obligations. Some issuers offer the choice to roll interest up and take it as a lump sum at maturity instead of receiving payments along the way.

Who issues property bonds, and why

Property bonds tend to be issued by small and mid-sized property developers or investment companies rather than large listed housebuilders. There's a practical reason for that. Bigger developers usually have access to cheaper senior bank debt. Smaller companies, or those working on projects a bank considers too niche or too risky to fully fund, often need to fill a gap in their capital stack. Loan notes let them raise that additional finance from private investors without giving up equity in the business or the project.

From the issuer's side, it's a way to raise capital outside the traditional banking system, with fewer covenants and more flexibility than a conventional loan facility. From the investor's side, the appeal is a fixed, predictable return that doesn't move with the stock market.

The security behind the bond

The word "secured" does a lot of work in property bond marketing, and it's worth understanding what it actually means before looking any further. In most cases, the issuer grants bondholders a charge over a property asset or portfolio of assets. This charge is a legal claim that, in theory, lets bondholders recover their money from the sale of that asset if the company can't pay.

Not all security is equal. Whether you hold a fixed charge or a floating charge, and whether you rank first or second behind other creditors, makes a real difference to what you'd actually recover if things went wrong. This is one of the most important, and most commonly glossed over, parts of the whole structure, which is why we've given it a full explainer of its own in how a property bond actually works, step by step.

How property bonds differ from buying property directly

The practical difference comes down to control and exposure. Buying a flat to let out gives you a real asset with the chance of capital growth, plus the hassle of being a landlord and full exposure if the local market falls. A property bond hands that complexity to someone else in exchange for giving up the upside: your return is fixed whether the underlying development is highly profitable or only just breaks even, provided the issuer can pay.

How property bonds differ from property funds and REITs

Property funds and real estate investment trusts (REITs) give you equity exposure, meaning you own a share of a portfolio of properties, or of a company that owns them, rather than lending money against them. That has consequences in both directions. A REIT's value can rise if the underlying portfolio performs well, but it can also fall, and REIT share prices tend to move with wider stock market sentiment as well as property fundamentals.

Open-ended property funds, meanwhile, have a history of suspending withdrawals during periods of market stress, precisely because property itself is slow and expensive to sell in a hurry. A property bond avoids that particular problem, since your return isn't tied to daily valuations, but it introduces its own liquidity issue instead. You generally can't get your capital out before the end of the fixed term at all, whatever the market is doing.

Typical rates and terms

Rates vary with the perceived risk of the issuer and the project, the length of the term, and where the bond sits in the security structure. Shorter-term bonds backed by a strong first charge over a completed, income-producing property tend to sit at the lower end. Longer-term bonds funding a speculative ground-up development, or subordinated behind other lenders, tend to sit higher, sometimes well above 12%, because that's compensation for genuinely greater risk of loss, not a free lunch. Our dedicated piece on current UK property bond rates looks at what drives that range in more detail.

Who tends to invest in property bonds

Since 2021, the FCA has permanently banned firms from mass-marketing this category of product, which it classifies as a speculative illiquid security, to ordinary retail investors. In practice, that means property bonds are generally only promoted to people who qualify as a self-certified sophisticated investor or a certified high net worth investor, following an assessment that the product is likely to be suitable for them. That restriction exists because these are genuinely high-risk products that have caused real harm to people who didn't fully understand what they were buying.

The risks in brief

UK investors don't have to look far for evidence that these risks are real rather than theoretical. Well-documented collapses such as London Capital & Finance and Blackmore Bond both left thousands of bondholders facing steep losses; in Blackmore's case, administrators indicated that recovery would likely amount to little more than a fraction of the £46 million originally invested. Our companion article on how returns, security and risk actually interact covers this in much more depth.

None of this means property bonds are inherently a poor choice for every investor; plenty of people hold them deliberately as part of a diversified income strategy. It does mean the marketing gloss of a fixed, attractive rate needs to be weighed carefully against the credit risk of the specific company standing behind it.
