Preferred equity vs mezzanine debt: how to choose the middle layer

Preferred equity and mezzanine debt do the same job in the capital stack: both sit above the developer's common equity and below the senior debt, closing the gap between what the senior lender will advance and the total cost of a scheme. The question of preferred equity versus mezzanine is really a question of form. One is a loan, the other is an ownership interest, and that distinction runs through cost, control and what happens if a deal goes wrong.

The core difference

Mezzanine debt is a loan. It carries an agreed rate, a second charge over the property, and an intercreditor agreement that sets out the mezzanine lender's rights relative to the senior lender. Preferred equity is not a loan at all. It is a preferred interest in the entity that owns the project, ranking ahead of common equity for returns but behind all the debt. The preferred equity investor is a part-owner with priority, not a secured lender.

That single difference explains most of what follows. A mezzanine lender enforces through its charge; a preferred equity investor enforces through rights written into the shareholder or membership agreement of the project entity.

All figures indicative; structures vary case by case.

Control: intercreditor versus shareholder agreement

Control is where the two diverge most. Because mezzanine debt is documented through an intercreditor agreement between the two lenders, the developer keeps ownership of the project entity outright. The mezzanine lender's rights are the rights of a secured creditor: a standstill period, cure rights, and enforcement of its charge if things fail. It does not sit on the ownership side of the table.

Preferred equity is different. The investor takes an interest in the entity, so its rights are governed by the shareholder or membership agreement. That usually brings consent rights over major decisions, and in a downside the preferred investor may be able to take control of the entity itself rather than enforce a charge. For a developer who wants to retain maximum autonomy, mezzanine debt is generally the cleaner structure. For an investor who wants governance rights, preferred equity can offer more.

Cost comparison

Mezzanine debt is usually the cheaper of the two. Because it is secured by a second charge and repaid before common equity, the mezzanine lender takes less risk than a preferred equity investor who has no charge and sits one rung lower. That lower risk shows up as a lower cost, indicatively from 12 percent a year against preferred returns that often target the high teens or low twenties, sometimes with a profit share on top. Both are more expensive than senior debt, and both look expensive in isolation until you blend them across the full stack.

When mezzanine debt fits

• The senior lender will permit a second charge and sign an intercreditor agreement, which most development lenders will.
• The developer wants to keep full ownership and control of the project entity.
• The scheme has a clear, single exit through sale or refinance from which the loan is repaid.
• Cost matters and the developer wants the lower-priced middle layer.

When preferred equity fits

• The senior lender will not allow a second charge, which can rule mezzanine out entirely.
• The structure needs to sit outside the debt, for accounting or covenant reasons.
• The provider wants governance rights and is willing to price for the extra risk of an unsecured position.
• The gap is larger or the risk higher than a mezzanine lender would take against a second charge alone.

The same gap, filled two ways

An illustrative example makes the choice concrete. Take a scheme where the senior lender advances £3.25m against £5m of cost, and the developer has £500k of equity. That leaves a £1.25m gap above the senior debt. Filled with mezzanine, the developer grants a second charge, the lender rolls up interest at an indicative 15 percent a year, and the developer keeps full ownership of the project entity throughout. Filled with preferred equity instead, the £1.25m comes in as a priority interest in the entity: no second charge, but the investor takes an agreed preferred return, often in the high teens, before the developer sees a profit, and usually some consent rights over major decisions. Same gap, same position in the stack, materially different cost and control. In most UK development cases the mezzanine route is cheaper and cleaner, which is why it is the default when the senior lender allows it.

What about the four types of preferred stock?

The four types of preferred stock, cumulative, non-cumulative, participating and convertible, come from the world of listed company shares, not property development. They describe how corporate preferred shares treat missed dividends, profit participation and conversion into ordinary shares. Real estate preferred equity borrows the priority principle from that world but is structured deal by deal in the project entity, so the neat four-way classification does not map onto a development. What carries across is the core idea: a preferred position is paid before the common holders, in exchange for giving up the open-ended upside.

Preferred equity vs private equity, and preferred versus common

Preferred equity is not the same as ordinary private equity or common equity. Common equity is the developer's own capital: last to be repaid, first to absorb loss, and entitled to all the upside once everyone else is paid. Preferred equity ranks ahead of common equity and takes an agreed preferred return before the common holders see a profit, but it gives up most of the unlimited upside in exchange for that priority. Private equity is a broader term for equity investment in a business or project; preferred equity is one specific, priority-ranked form of it.

UK development context

In UK property development the middle layer is most often mezzanine debt. Senior development lenders here are used to second charges and intercreditor agreements, the documents are well trodden, and mezzanine is the lower-cost option, so it tends to win. Preferred equity appears when a senior lender will not sit above a second charge, when the entity structure calls for it, or when the gap is large enough that an equity-style provider is the natural fit. Where a scheme needs genuine equity partners rather than a priority return, JV equity covers that market.

We lend the mezzanine layer ourselves and, where a case suits preferred equity or a different structure better, we arrange it whole of market. The starting point is the same for both: the full picture of your capital stack and a realistic exit. Send us the deal and we will tell you honestly which middle layer fits.
