Mezzanine Finance vs Equity Funding: Choosing the Right Capital Stack

Every property development is funded through a capital stack: layers of finance with different risk profiles, costs, and claims on the project’s profits. At the bottom is senior debt (cheapest, first claim). At the top is developer equity (most expensive, last claim). The middle layers - mezzanine and equity - are where most developers have choices to make.

The fundamental trade-off is simple: mezzanine finance is debt (you repay it with interest), while equity funding gives an investor a share of ownership and profits. Both reduce the cash you need to put in, but they affect your returns and control very differently.

Mezzanine finance is a subordinated loan that sits behind senior debt in the capital stack. It stretches your total borrowing from the typical 65-70% LTGDV of senior debt up to 85-90% LTGDV, dramatically reducing the equity you need to inject.

Rates are higher than senior debt - typically from 12% per annum - reflecting the additional risk the mezzanine lender takes by ranking behind the senior lender in any recovery scenario. Terms mirror the development programme at 12-24 months.

Crucially, mezzanine is debt: you owe a fixed return regardless of how profitable the project is. If your scheme delivers a 25% profit margin, you keep everything above the mezzanine interest cost. The lender gets their 12% and nothing more.

Equity funding involves bringing in a capital partner - typically a family office, HNW individual, or property fund - who provides cash in exchange for a share of the project’s profits. There is no fixed interest rate; instead, the investor takes a profit share starting from around 40%.

Equity can cover up to 100% of costs when combined with senior debt. In a joint venture (JV) structure, the equity partner may fund everything from the land deposit to the build contingency, while you contribute your development expertise and management time.

The key difference from mezzanine: equity partners share in both the upside and the downside. If the project makes £1M profit, they take their agreed share. If it makes £3M, they take a proportionally larger amount. With mezzanine, the cost is fixed regardless of profit.

Cost structure: Mezzanine charges a fixed interest rate from 12% p.a. Equity takes a profit share from 40%. On a highly profitable scheme, mezzanine is cheaper. On a marginal scheme, equity may be less risky for the developer since there is no fixed repayment obligation.

Control: Mezzanine lenders typically do not take a seat at the table - they monitor via the same surveyor as the senior lender. Equity partners often want board seats, approval rights on key decisions, and regular reporting. This can slow down decision-making on site.

Total borrowing: Mezzanine stretches to 85-90% LTGDV. Equity can cover 100% of costs in a full JV. If you have minimal cash to invest, equity may be your only option.

Risk profile: Mezzanine must be repaid regardless of project outcome - it adds leverage and therefore risk. Equity shares the downside: if the project loses money, the equity partner absorbs losses proportionally.

Speed: Mezzanine facilities can often be arranged within the same timeline as senior debt (4-8 weeks). Equity and JV negotiations typically take 8-12 weeks due to legal structuring, shareholder agreements, and due diligence.

Mezzanine is the right choice when you have a scheme with strong margins (20%+ profit on GDV) and want to maximise your return on equity. By borrowing more at a fixed cost, you keep a larger share of the profit upside.

It also makes sense when you want to retain full control of the project, when you have a track record that mezzanine lenders will back, and when you have enough equity for the remaining 10-15% the mezzanine does not cover.

Example: On a £5M GDV scheme with £1M profit, using mezzanine at 12% on a £1M facility costs approximately £180,000 over 18 months. You retain £820,000 profit. With equity at 40% profit share, the investor takes £400,000 and you retain £600,000.

Equity is the better choice when you lack the personal capital to cover the gap between senior debt and total costs, when you are taking on a larger or riskier scheme than your balance sheet can support, or when you want a partner who brings more than just capital (contacts, expertise, operational support).

First-time developers often need equity partners because mezzanine lenders require a track record of 2-3 completed schemes. A credible equity partner can also strengthen your application to senior lenders.

Equity also makes sense on very large schemes (£10M+ GDV) where the absolute profit is large enough that sharing it still delivers an attractive return, and the capital efficiency of not tying up your own cash across a long programme is valuable.

We have relationships with both specialist mezzanine lenders and equity providers. Our role is to model your capital stack, show you the cost implications of each option, and connect you with the right partners for your specific scheme.

In many cases, the optimal structure is a blend: senior debt covering 65% LTGDV, mezzanine stretching to 85%, and developer equity covering the final 15%. We can arrange the entire stack through a single process, saving you time and ensuring the intercreditor terms work for everyone.

For developers exploring other funding options, we also arrange bridging loans and development finance.

When comparing property finance options, consider the regulatory framework: the Financial Conduct Authority (FCA) regulates certain types of lending, while RICS standards govern valuations across all product types. HM Land Registry registration applies to all secured lending, and Building Regulations compliance affects the exit valuation regardless of which finance product you use.
