What Are Property Bonds?

If you're an investor looking to invest in property, or if you're a property developer looking for finance for a project, you might be considering property bonds. Here we look at what property bonds are and how they work.

What Exactly is a Property Bond?

A property bond (also known as a property investment bond) is a secured loan between an investor and a property development or investment company. Essentially, it is a contract between a lender and a borrower. The lender lends an agreed amount of money over an agreed period for a financial return.

Property bonds work on similar principles to corporate bonds or loan notes, where companies raise funds to finance their activities. With property bonds, those activities are property projects, most frequently, property developments.

Property bonds can also be considered to be both an alternative investment product and an alternative finance product.

For readers comparing bonds with direct property ownership, PIUK also lists investment property, buy-to-let property for sale and below-market-value property for sale.

How They Work

Every individual property bond is different. Each property bond will have a term, interest rate, conditions and risk-return profile.

Investors can invest various amounts, from as little as £1,000 to several hundreds of thousands of pounds. The limits of the investment will depend on the bond.

Bonds can be issued for any period. But there is usually a minimum term of one year and a maximum of five years.

The rate of interest or coupon on a property bond is agreed upon at the outset and is fixed. Interest may be paid monthly, quarterly or annually. Capital will be repaid on maturity. The actual interest rate will depend on the relevant individual project and may be related to its riskiness.

Property bonds may involve investing in residential or commercial buildings or land. They may involve new build developments, property developments, refurbishments, renovations and conversions.

A property bond is technically a secured loan. The borrower will pledge an asset, usually a property, as security for the loan. A first charge (sometimes a second) will then be placed in favour of the lender to officiate that security. In many ways, a property bond is a form of a private mortgage.

After the charge has been placed and the terms and conditions of the property bond are agreed upon, a contract or loan note is issued. This states what the funds may be used for, the interest rate, additional costs, when the interest and capital are to be repaid, and what security is being provided.

An investment into a property bond may be made into a Special Purpose Vehicle created specifically for that project.

Sometimes, property bonds will be supervised by an independent security trustee. The trustee will be impartial but act in the interests of the bondholders. They will also take charge of the assets which are pledged as security.

The Advantages

Property bonds can offer several advantages for investors:

• They offer a fixed rate of interest over a defined timescale.
• They can offer a high rate of interest. Some bonds have been known to have an interest rate of 15% pa, for example.
• They are asset-backed investments secured via a legal charge on a property.
• They tend to be more predictable and less volatile than other investments, such as stocks and shares.
• They are a convenient, simple way of investing in property without the need to buy or own it or do any of the hands-on work that property investment typically involves. Therefore they are a way of benefitting from the high returns that property development, renovation, refurbishment and construction projects can offer without the investor having to be involved with the day-to-day work.

• There may be tax advantages to those investing in property bonds. It may be possible to invest in them via an Innovative Finance ISA (IFISA), Self-Invested Personal Pension (SIPP) or Small Self Administered Scheme (SSAS).

  There may also be Capital Gains Tax (CGT) advantages compared to buying and owning property.
• Typically, property bonds do not include fees for their investors.

Property bonds offer several advantages for borrowers too. They allow them to borrow more of the investment needed for a project than a commercial bank would be prepared to lend on more favourable terms. A commercial bank might only be willing to lend up to 50% of the amount needed for a property project. Much more than that can be raised using a bond.

Property bonds allow developers to borrow money to fund a property project that commercial banks would not be prepared to lend on. These could be riskier projects with a higher risk of failure but a higher upside potential.

The Risks

Investing in property bonds involves some risks. These will vary according to the individual bond.

Property bonds involve a risk that you will lose some or all of your investment. As the often-heard disclaimer goes, your capital is at risk. Your returns are not guaranteed.

While it is true that if the borrower defaults or even becomes insolvent, the lender will have a legal charge over the security that has been pledged, there is always a risk that this will prove insufficient to repay the investment.

With property bonds, the relevant project and the riskiness of the investment need to be assessed together. That review includes the bond issuer's experience, the viability of the project, whether the security is sufficient and the asset-to-liability ratio for that particular bond.

As is normal with most bonds, your capital will be locked in. As is typical with most types of bonds, you can only remove your capital once the term is complete (the bond has matured). Property bonds are illiquid investments.

The regulatory and compensation position depends on the product and the service surrounding it. The Financial Services Compensation Scheme explains that issuing a mini-bond is generally not a regulated activity, so money invested directly in the bond is not normally protected by the FSCS. Separate regulated services, such as investment advice or arranging provided by an authorised firm, may be protected when the FSCS eligibility conditions are met.

Interest Rates

Interest rates offered by property bonds are not directly linked to the base rate. Interest rates are based on a meeting point between what borrowers are willing to pay and what lenders are willing to lend at.

Property bonds currently on the market offer interest rates between 4% and 15%.

The interest rate on a particular property bond will generally relate to its term and how risky the investment is considered to be. Shorter-term bonds tend to offer lower interest rates. Long-term bonds tend to have higher interest rates. High interest can mean that the project being financed is considered relatively risky.

The project and the interest rate need to be considered together, because a higher return can indicate higher risk. An investor's own risk tolerance is a separate personal consideration.

Property Bond Eligibility and Access Rules

Property bonds are a financial vehicle for companies who want to raise finance for property projects and investors interested in investing in property projects. They tend to be issued by property developers, construction companies and builders.

Access depends on the product and how it is promoted. Not every investment described as a property bond is limited to high-net-worth investors, but the FCA restricts promotions of speculative illiquid securities to permitted investor categories and applies additional risk-warning and appropriateness rules.

One permitted category is a certified high-net-worth investor. The current FCA declaration uses annual income of at least £100,000 or net assets of at least £250,000, with specified exclusions including a person's main home and pension rights. Separate exemptions and tests apply to sophisticated investors.

How to Invest

Property bonds can be bought directly from a property development or investment company. However, they are usually purchased through a lender or intermediary: a specialist.

Independent financial and tax advice can help an investor assess a specific property bond and their own circumstances before committing money.

In the future, you may also see property bonds and real estate tokenisation merge with funding not just for real-life property assets but also for digital assets and transactions.
