Mezzanine development finance to fill the equity gap
Mezzanine development finance is a supplementary layer of funding that sits behind the senior development loan and ahead of your own equity. It can reduce the cash you need to commit to a viable scheme, at a higher cost than senior debt.
- Sits behind senior debt
- The senior lender usually takes first position, with mezzanine funding layered in behind.
- Equity gap funding
- Can cover part of the gap between the senior loan and total project cost.
- Higher cost of capital
- Priced above senior debt to reflect its subordinate position in the capital stack.
- For viable schemes
- Suits experienced developers on well-structured schemes with clear profits and a credible exit.

Mezzanine development finance is a supplementary layer of project funding used to bridge the gap between senior development debt and the developer’s own equity. It can help increase leverage on viable development projects where the core scheme works but the funding stack needs additional support.
What Is Mezzanine Development Finance?
Mezzanine finance sits behind the senior development facility and ahead of the developer’s own equity in the capital stack. It is designed to help fill a funding gap where the senior lender will not cover the full requirement.
It is not a replacement for a strong project. It is an additional funding layer used where the scheme is already viable.
When Mezzanine Funding Is Used
Mezzanine development finance is often used when a project has a solid development case but the developer wants to reduce the amount of equity being tied in or needs help covering the gap between senior debt and total project cost.
It is more common on structured or larger schemes than on simple small builds.
How It Sits Alongside Senior Development Debt
The senior lender usually sits in first position, with mezzanine funding layered in behind that. Because of that position, mezzanine lenders usually look very closely at the quality of the project and the strength of the exit.
The whole stack has to make sense. Mezzanine finance only works well when the rest of the project is already strong. To understand how mezzanine funding fits within the wider capital stack, Development Finance provides a broader overview of development lending structures and project funding stages.
Who This Type of Funding Suits
This type of funding is generally more suitable for experienced developers, well-structured schemes, and projects where the economics are clear.
It is not usually the first place to look for a weak or uncertain project. It works best where there is already a solid senior debt base and a credible path to exit. Developers working on housing schemes may also benefit from reviewing Residential Development Finance to understand funding options for residential-led projects.
What Lenders Look For
Mezzanine lenders will assess the quality of the scheme, the senior debt position, borrower experience, projected profits, and the overall viability of the stack.
Because this is higher-risk capital, presentation and project discipline matter a lot. For larger mixed-use or business-focused schemes, Commercial Development Finance explains how lenders assess viability, project complexity, and commercial exit strategies.
How the capital stack fits together
A development is usually funded in layers. The senior lender typically provides the main facility and is repaid first. Mezzanine finance sits behind it, and the developer's equity sits at the bottom, absorbing any shortfall before either lender is affected. As an illustration, a scheme with total costs of £2,000,000 and senior lending at 70% of cost leaves £600,000 to find. Mezzanine finance could cover part of that gap, leaving less of the developer's own cash tied into the project.
Preparing a mezzanine application
Mezzanine lenders expect the same core information as a senior lender, presented with extra care:
- The senior lender's terms or indicative offer
- A full development appraisal showing costs, finance costs and projected profit
- A detailed cost plan and build programme
- Planning documents and details of the professional team
- Evidence of your track record on similar schemes
- Comparable evidence supporting the end value and exit
Costs to expect
Because it carries more risk, mezzanine finance is priced above senior debt. As well as interest, expect arrangement fees, valuation and legal costs, and bear in mind that a second funder brings its own due diligence and legal documentation. Ask how interest and fees are charged and when they are payable, as this affects the net funds available. The combined cost of both layers needs to sit comfortably within the projected profit.
How a mezzanine deal comes together
The senior facility is normally shaped first, because the mezzanine lender needs to understand the senior terms before agreeing its own. Both lenders review the scheme, the cost plan, the valuation and the exit. The arrangement between them is then documented so the order of repayment is clear, and funds are released through the build in line with the agreed drawdown process.
Risks and repaying the facility
Adding mezzanine finance increases total borrowing on the scheme, so cost overruns, delays or lower sale prices reduce the developer's margin more quickly. Repayment comes from the same exit as the senior loan, normally a sale of the completed units or a refinance, with the senior lender repaid first. A realistic contingency, a well-evidenced end value and a clear timeline matter even more when two lenders are relying on the same project.
