Property Bonds Explained: How They Work and the Risks

A property bond is a loan. An investor lends money to a property company, usually a developer, for a fixed term at a fixed rate of interest. The loan is normally secured by a legal charge over a property or a site, and the capital is due back when the bond matures. The money funds building work, conversions or land purchases that a bank either would not fund or would only part-fund.

Two protections people often assume are there usually are not. Money put directly into this kind of bond is not normally covered by the Financial Services Compensation Scheme if the issuer fails. And the FCA does not allow the most speculative versions to be mass-marketed to ordinary retail investors, under its promotion rules for non-mass market investments. Capital is at risk and returns are not guaranteed.

One naming mix-up is worth clearing up early. The Holiday Property Bond is a different product altogether: a life assurance bond that gives investors access to a portfolio of holiday homes, with returns its provider says come purely in the form of holidays. Everything that follows here is about property investment bonds, the loan-note kind.

What Exactly is a Property Bond?

A property bond, also called a property investment bond, is a loan agreement, normally a secured one, between an investor and a property company. It works on the same principles as a corporate bond or loan note: a company borrows money from investors to fund its activities and pays interest for the privilege. With property bonds, the activity is a property project, most often a development.

The paperwork is a loan note. It sets out what the money can be used for, the interest rate, when interest and capital fall due, and what security sits behind the loan. Where the bond is secured, the borrower pledges an asset, usually the property or site being developed, and a first or second legal charge is registered in favour of the lenders. A first charge gets paid first if things go wrong. A second charge queues behind whoever holds the first, which is often a bank.

Many issuers raise the money through a Special Purpose Vehicle, a company set up just for that project. Some appoint an independent security trustee, whose job is to hold the security and act for the bondholders rather than the borrower. What a trustee can actually do depends on the security documents, and the arrangement does not make the issuer FCA-authorised, bring the bond inside the FSCS, or guarantee that the security recovers the money.

The FCA groups most of these products with mini-bonds, which its consumer guidance describes as "an IOU issued by a company (or 'issuer') to an investor in exchange for a fixed rate of interest over a set period". The same guidance classes them as high-risk investments, usually issued by small companies or by businesses that find it hard to raise funds from large investors.

How They Work

Every bond is different. Each has its own term, interest rate, payment schedule and security package, and the detail lives in the loan note rather than in any industry standard. Minimum investments, terms and structures vary from issuer to issuer, so the loan note is the document that answers most questions about a specific bond.

The interest rate, sometimes called the coupon, is agreed at the outset and fixed. Interest may be paid monthly, quarterly, annually or rolled up and paid at maturity, when the capital is also repaid. Until maturity the money is normally locked in. Property bonds are usually unlisted, so there is normally no secondary market to sell into if circumstances change.

The projects behind the bonds cover most of the property world: new-build developments, conversions, refurbishments, commercial buildings and land.

From the issuer's side, the appeal is simple. Banks often lend only part of what a project needs, and some projects fall outside what a bank will fund at all. A bond fills the gap, at a price. It is one of several routes developers use when raising property finance, and the interest offered to bondholders reflects what that borrowing is worth to the company.

Interest Rates

Rates on property bonds are not tied to the Bank of England base rate. Each issuer sets a rate that reflects what it needs to pay to attract lenders, which in turn reflects what banks would charge it, or whether banks would lend to it at all.

Read that way, the advertised rate is information about the borrower as much as reward for the lender. A company offering well above what banks pay savers is paying that premium for a reason. The FCA put it directly when it confirmed the marketing ban: "Consumers should always be wary of any investment promising high returns while downplaying risks", a line from its announcement of the permanent rules.

How Property Bonds Compare With Other Bonds

"Bond" covers a wide family, and the differences matter more than the shared name.

Government bonds, called gilts in the UK, are loans to the government. They trade daily on open markets and can normally be sold before maturity, at the prevailing price and subject to liquidity. Listed corporate bonds and retail bonds also trade on a stock exchange, can normally be sold before maturity, and come with the disclosure requirements that listing brings. Both are bought through a stockbroker or an investment platform.

Property bonds in the UK sit at the other end. They are usually unlisted, so there is normally no secondary market to sell into, and early exit is generally unavailable unless the terms of the loan note or a willing buyer permit it. They are bought directly from the issuer or through an intermediary promoting them, which is exactly where the FCA's promotion rules apply. The FSCS is also direct about who can issue them: "Businesses don't have to be regulated by the FCA to issue mini-bonds". Issuing one is generally not a regulated activity, so the company borrowing the money may sit outside FCA supervision entirely, even when the promotion that advertised it was approved by a regulated firm.

Unlisted bonds are sometimes described as steadier than shares because their value does not jump around day to day. The absence of a daily price is not the absence of movement in what the loan is worth. It means nobody publishes that value between issue and maturity, so the first hard update an investor gets may be the one that matters most: whether the issuer repays.

The Risks

Capital risk comes first. If the project fails or the issuer becomes insolvent, some or all of the money can be lost. The security is meant to cover that outcome, and sometimes it does. It can also prove insufficient: a half-finished development is worth less than a finished one, a valuation made in a rising market can look optimistic in a falling one, and a second charge only gets paid after the first-charge lender has taken what it is owed.

Lock-in is the second. The capital cannot normally be withdrawn before the bond matures, whatever happens to the investor's own circumstances in the meantime. An investor who needs the money early normally has no exchange to sell on and depends on the issuer agreeing to an early exit, which the loan note rarely requires.

Then there is the compensation position. The FSCS explains that if a mini-bond issuer fails, the scheme is unlikely to be able to compensate the people who invested directly. What the scheme does protect is regulated investment services around the bond, such as advice from an authorised firm, when its eligibility conditions are met. The bond itself is not covered.

The regulator's own record shows how seriously it takes this market. One failure shows the scale involved: London Capital & Finance entered administration on 30 January 2019, with around 11,600 bondholders holding bonds worth £237m. A temporary ban on promoting speculative mini-bonds to retail investors was introduced in January 2020, in the FCA's words "following serious concerns that speculative mini-bonds were being promoted to retail investors who neither understood the risks involved, nor could afford the potential financial losses". The ban was made permanent from 1 January 2021, confirmed in the FCA's policy statement PS20/15.

Who Can Be Offered a Property Bond?

The FCA's rulebook decides who can even see the marketing. Under COBS 4.12B, a speculative illiquid security, broadly a debenture, a form of loan note, where the money raised is lent on to others, used to buy investments, or used to buy or build property, cannot be promoted to retail clients in general. Most property bonds fit that description. Firms may only promote them to a short list of categories: certified high net worth investors, certified sophisticated investors and self-certified sophisticated investors. Even then the rulebook adds safeguards: a preliminary assessment of suitability on the high net worth and self-certified sophisticated routes, and, the first time a particular promoter puts such an investment to a particular person, a personalised risk warning and a 24-hour cooling-off period.

The high net worth declaration currently means an annual income of at least £100,000 in the last financial year, not counting one-off pension withdrawals, or net assets of at least £250,000. The statement's own wording excludes from net assets a main home, any loan secured on it or equity released from it, pensions and pension withdrawals, and rights under insurance contracts. Those figures moved twice in 2024: raised in January, then put back to £100,000 and £250,000 by an amending order that took effect on 27 March 2024. The self-certified sophisticated routes set out in the same order include being a director of a company with annual turnover of at least £1 million, or having made two or more investments in unlisted companies in the two years before signing the statement.

Property-backed products that fall outside the speculative illiquid definition may instead count as restricted mass market investments under COBS 4.12A. Those can be promoted more widely, but must carry the FCA's prescribed risk warning, which begins "Don't invest unless you're prepared to lose all the money you invest", and direct offers carry cooling-off and appropriateness requirements of their own before an application goes through.

How to Check a Property Bond Issuer

Three free checks exist. The first two are run by the FCA, the third by Companies House.

The Financial Services Register lists the firms and individuals the FCA and PRA have authorised, now or in the past, and what activities each has permission for. Searching the firm behind a promotion shows whether it is authorised and for what. Because issuing a bond is generally not a regulated activity, the issuer itself may legitimately be absent from the register; the firms that approved the promotion, or that give advice on the bond, are where authorisation can be checked. The FCA also warns that scammers copy genuine authorised firms, which it calls clone firms, so contact a firm using the details shown on its register entry, never the details printed on the promotion itself.

The FCA Warning List shows the firms the regulator is concerned are working without its permission. The FCA is plain that absence from the list proves nothing, because unauthorised firms change names faster than any list can track them.

The issuer itself, the company the register legitimately misses, can be inspected at Companies House. The free company information service shows images of the documents a company has filed, its mortgage charge data, which records the charges on the company register and who is stated to be entitled to them, and its current and resigned officers. The record has limits: a company does not have to tell Companies House when a charge is paid off, so whether a recorded charge is still live, and what it actually secures, sits in the charge documents and the property title rather than the register alone.

The FCA's scam-protection guidance describes the recurring warning signs it sees in investment scams: pressure to act quickly, bonuses for investing fast, and offers that sound too good to be true. The same guidance covers what to do after the event: anyone who thinks they have already been caught by a scam can report it to the FCA by phone or through its contact form.

Tax wrappers get used as a selling point here too. GOV.UK lists what an innovative finance ISA can include, such as peer-to-peer loans and crowdfunding debentures, and some bonds are structured to qualify. The FCA has also warned about promotions that wrongly claimed ISA status, so an ISA label on a bond advert is a claim to verify with the ISA manager, not a fact to take from the advert.

Property Bonds vs Buying Property Directly

The comparison most investors are actually weighing is between lending to a developer and owning a property themselves.

Worth stating plainly before the comparison: this site's business is property, not bonds. I have bought and owned UK investment property for more than 20 years, so it is the ownership side of this page I know from the inside. This page is general information about how the product works, not advice, and whether any particular bond fits any particular investor is a question for an authorised financial adviser.

A bondholder is a lender. The return is the fixed coupon and nothing more, the exposure is to one issuer and one project, and there is no rent, no tenant, no maintenance and no share of any gain if the project does well. An owner of investment property holds the asset itself: rental income that can rise or fall, price movement in either direction, and the full list of responsibilities that come with ownership. For anyone weighing up the ownership side, our guide on getting started in property investing sets out the main ways to start, from a single buy-to-let to keeping some properties and selling others to pay for the next one.

Ownership also comes in different entry shapes. Buy to let property for sale ranges from ready-tenanted flats to off-plan units, and below market value properties are homes offered at a discount to comparable local market values, a different entry price rather than a different structure. Other structures keep appearing between lending and owning: real estate tokenisation splits ownership of a building into digital units, a different mechanism again from a loan note.
