Mezzanine finance and the capital stack in property development

How the capital stack ranks a development scheme

The capital stack is the ranked order in which each source of funding for a scheme is repaid and takes its risk. It is worth drawing before you reach for any single layer, because a pound's position in the stack sets both what it costs and how safe it is. Senior debt sits at the base, repaid first and priced lowest because it is furthest from loss. Developer equity sits at the top, repaid last and rewarded with the residual profit precisely because it absorbs the first hit if the scheme disappoints. Everything else, including mezzanine finance, sits between those two extremes.

A simple scheme has only two layers, senior debt and the developer's equity. As a project stretches, more layers appear to fill the gap: stretch senior pushes the main loan higher up the cost, mezzanine finance slots in as a junior loan, and preferred equity sits higher still, taking a return ahead of the developer's own profit. The table below shows the usual order, the security each layer holds and, illustratively, how their cost compares. The cost column is relative and for illustration only, not an offer of finance.

Stretch senior and preferred equity are optional layers, not fixtures, and whether they appear depends on the lender you place the deal with and the shape of the scheme. That is the first thing the stack teaches: mezzanine finance is one answer to the gap above senior debt, and it competes with the layers directly above and below it rather than standing alone.

What mezzanine finance is and how a second charge secures it

Mezzanine finance is a subordinated loan that bridges the gap between the senior development loan and the equity a developer would otherwise have to put in. It behaves like debt, with an agreed coupon and a fixed repayment at exit, but it sits in a junior position and shoulders more risk than the senior loan, so its cost lands nearer that of equity than of debt. In a development finance stack it is the layer that lets a developer commit less cash and still fund the scheme in full, without giving away a share of the profit the way a joint venture would.

The security is what sets mezzanine finance apart from a simple top-up. Typically it takes a second charge over the site, sitting one rank below the senior lender on the security, and the directors almost always give a personal guarantee as well. Both lenders end up secured against the same asset, and a document known as an intercreditor deed, or deed of priority, spells out that the senior lender takes precedence over the mezzanine lender across both the security and the eventual sale proceeds. Until that intercreditor deed is signed, a mezzanine facility rarely amounts to more than an offer in principle. Lenders such as United Trust Bank and Atelier publicly operate in the development and mezzanine market, though criteria change constantly and nothing here is an offer of finance.

When mezzanine makes the deal work, and when it eats the margin

Mezzanine finance earns its place when it lets a strong scheme proceed on less cash, and it destroys value when it is bolted onto a scheme whose margin is already tight. The deciding factor is the profit on cost. Because the junior layer is expensive, it has to be paid for out of the same profit the developer is trying to protect, so the headroom in the appraisal matters more than the leverage on offer.

Consider an illustrative scheme with a total development cost of 3 million pounds. Senior debt is capped at 65 percent of cost, mezzanine tops the debt up to 90 percent of loan-to-cost, and the developer covers the balance. Treat every number below as illustrative only, never an offer of finance.

On a strong scheme, say a gross development value of 4 million pounds and a gross profit near 1 million pounds, an illustrative rolled-up mezzanine cost of 110,000 to 140,000 pounds over the term is a small slice of that profit, and the layer has done its job: it cuts the cash contribution from around 900,000 pounds to 300,000 pounds and frees 600,000 pounds for other sites. Drop the gross development value to 3.4 million pounds and the gross profit to around 400,000 pounds, and that same mezzanine cost plus senior finance and sales costs can eat most of the margin. The leverage is identical in both cases; the outcome is not, because the profit is what pays for the junior layer.

Stretch senior, the layer that can make mezzanine redundant

Stretch senior is a single development facility that reaches higher up the cost than a standard senior loan, often to around 75 percent of loan-to-cost or a similar share of gross development value, from one lender under one first charge. It occupies much of the ground mezzanine finance was designed to fill, which is why, on many schemes, it quietly removes the case for a second layer altogether. Where one lender will stretch to the leverage the developer needs, there is no gap left for mezzanine to fill.

The attraction of stretch senior is not only the leverage but the simplicity. One lender, one charge, one facility agreement and one set of costs means no intercreditor deed to negotiate, no second legal team, and no risk of two funders disagreeing at exit. Blended across the whole loan, a single stretch facility is frequently cheaper than a senior loan plus a mezzanine top-up, even though the stretch tranche itself is priced above the senior base.

• One lender and one first charge remove the intercreditor deed and the second set of legal costs
• A blended rate across the whole facility often beats senior debt plus a separate mezzanine coupon
• There is a single point of consent for drawdowns, variations and sales, not two funders to align
• At exit there is one loan to redeem, which keeps a later refinance or exit bridge clean

Mezzanine finance still wins where the developer needs to push past the leverage a single lender will stretch to, where the senior lender simply will not go higher, or where keeping the senior loan smaller protects its pricing. The point is to compare the two before defaulting to a second charge. We model stretch senior against a senior-plus-mezzanine structure on the same scheme and place whichever leaves more profit intact. Every figure quoted here is for illustration and is not an offer of finance.

The intercreditor deed developers underestimate

The intercreditor deed is the agreement between the senior lender and the mezzanine lender that governs how they coexist behind the same asset. Developers tend to treat it as a formality between the two funders, but its terms decide how much freedom the mezzanine lender has, how quickly a problem can be enforced, and how sale proceeds are split. It is negotiated between the lenders, yet it shapes the developer's position at every difficult moment in the scheme.

• A standstill provision stops the mezzanine lender enforcing its second charge for a set period even if it is owed money, giving the senior lender first control
• A priority cap fixes the maximum the senior lender can recover ahead of the mezzanine lender, so unplanned senior cost overruns do not silently subordinate the junior layer further
• Consent rights decide who must approve a sale, a variation or a further drawdown, which can slow a completed scheme if two funders have to agree
• The order of application of proceeds sets exactly how sale money flows: senior debt first, then the mezzanine facility, then the developer, with no room to reorder it at exit

The friction developers underestimate is time and cost, not just theory. Negotiating an intercreditor deed adds legal fees and can add weeks to completion, because two lenders and two legal teams have to agree terms before a penny is drawn. On a fast scheme that delay can outweigh the benefit of the extra leverage. It is one more reason to check whether stretch senior removes the need for a second lender before committing to the mezzanine route.

What happens to mezzanine at exit

At exit the intercreditor deed does exactly what it was written to do: it fixes the order of repayment when the money finally arrives. Whether the scheme is redeemed by unit sales or by a refinance, the senior lender with the first charge is repaid first, the mezzanine lender, holding the second charge, is settled after that once the senior balance has gone, leaving the developer's equity and profit to come out last. The order never bends at redemption, which is why the margin has to be strong enough to reach the junior layer and still leave a profit.

1. Complete the scheme and either begin the sales period or arrange a refinance onto longer-term debt.
2. Apply the proceeds to the senior loan first, clearing the first charge under the deed.
3. Clear the mezzanine facility in full out of what is left, which lifts the second charge.
4. Return the developer's own equity, plus the residual profit, only once both debt layers are cleared.

A common exit is a bridge that repays the development debt during the sales period, and here the second charge matters. An exit bridge lender takes its own first charge, so an existing mezzanine second charge has to be dealt with before it can complete. In practice the bridge either refinances both layers together and redeems the mezzanine as part of the new advance, or the mezzanine is cleared first, or the mezzanine lender agrees to sit behind the new bridge under a fresh intercreditor deed. Most bridge lenders prefer a clean first charge, so an outstanding second charge that is not being redeemed can narrow the field or slow the deal. An exit bridge here runs, indicatively, between 0.65 and 0.95 percent a month across a term of 6 to 18 months, and we line the exit up early so the second charge is dealt with before it turns into a bottleneck.

Mezzanine finance set against preferred equity

Mezzanine finance and preferred equity both fill the space above senior debt, but they rank differently. Mezzanine is debt: it usually takes a second charge, carries a defined coupon, and is repaid before the developer sees any profit. Preferred equity is an equity layer above the debt, often without a charge at all, taking an agreed return or preferred internal rate of return ahead of the developer's common equity but behind everything owed to the lenders. It sits closer to the developer's money than mezzanine does, and it is repaid later.

The practical difference shows when a scheme is under pressure. A mezzanine lender holding a second charge has enforcement rights and a fixed repayment, so it behaves like a creditor. A preferred equity investor is usually paid only when the numbers allow and ranks after the debt, so it shares more of the downside and often expects a higher return in exchange. We assess mezzanine, preferred equity and stretch senior side by side and place the structure that leaves the developer with the most profit and the cleanest exit. Nothing here is an offer of finance.
