Securing funding for a multi-unit development project in the UK requires a clear understanding of the finance structures available and how each one suits different project sizes, developer experience levels, and equity positions. Whether you are building a block of flats, converting a commercial property into apartments, or developing a phased housing scheme, the right finance structure can significantly affect your profitability and cash flow. This guide breaks down the leading development finance options for multi-unit projects, compares their key features, and explains how to choose the best fit for your next scheme.

What Is Multi-Unit Development Finance?

Multi-unit development finance is a specialist short-term funding product designed to cover the land acquisition and construction costs of projects that deliver multiple residential or commercial units. Unlike a standard mortgage, this type of lending is assessed against the Gross Development Value (GDV), which is the projected open market value of all completed units.

According to UK Government housing supply data, the country still delivers only around 230,000 homes annually against a target of 340,000, creating strong ongoing demand for multi-unit residential development funding. Lender appetite is currently strongest for schemes of 5 to 50 units in commuter belts and core regional cities such as Manchester, Leeds, and Birmingham.

Senior Development Finance (Senior Debt)

Senior debt is the most common form of development finance for multi-unit projects. It is a first-charge loan secured against the development site, with funds drawn down in stages as construction progresses. Most lenders cap borrowing at 60 to 70% of GDV, with loan-to-cost ratios of up to 85 to 90% for experienced developers.

Interest is typically rolled up into the facility and repaid on completion or as individual units are sold. On multi-unit developments, the outstanding debt reduces with each completed unit sale, which means your finance costs actively decrease as you sell through the scheme. This staged repayment structure is a key advantage for multi-unit projects over single-unit builds.

Developer Money Market provides access to over 320 property development finance products from more than 120 specialist lenders, covering senior debt facilities from £25,000 to £50 million.

Stretch Finance for Higher Leverage

Stretch finance is a single-facility loan that provides a higher loan-to-cost ratio than traditional senior debt, typically up to 80 to 85% of total project costs. It is structured as one loan from a single lender, avoiding the complexity of layering separate debt facilities. This makes it particularly useful for developers who have limited equity to contribute but still want competitive terms.

Stretch funding can help a developer obtain a higher loan to cost than traditional development finance. Learn more about how the stretch funding structure works and the criteria required to qualify.

Mezzanine Funding to Bridge the Equity Gap

Mezzanine finance is a second-charge loan that sits behind the senior debt facility to bridge the gap between what a senior lender will provide and the equity a developer has available. If a senior lender offers 65% of total costs and the developer can only contribute 10%, mezzanine finance can fill the remaining 25%.

Because mezzanine lenders take on higher risk through a subordinated charge, interest rates are typically higher, ranging from around 15 to 24% per annum. Most providers require developers to demonstrate a successful track record and contribute a minimum of 10% of build costs as their own equity. Explore the criteria for raising mezzanine funding in detail.

100% Joint Venture (JV) Funding

Joint venture development finance is a funding structure where a lender or investment partner provides up to 100% of the acquisition, build, and professional costs. The developer does not need to contribute cash equity, making it an attractive option when capital is tied up in other projects.

JV facilities between £500,000 and £4 million are the most common, but funding up to £20 million is possible. Developers will need to demonstrate significant experience and a proven track record. Profits are typically split between the developer and the JV funder, often around 50:50. Developer Money Market is a specialist in JV property development finance and can help source bespoke solutions.

Bridging Finance for Site Acquisition

Bridging finance is a short-term loan, typically lasting 3 to 12 months, used to secure a development site quickly before longer-term development finance is arranged. It is particularly useful for acquiring land at auction or before planning permission has been granted. A typical use case for multi-unit developers is to bridge a site purchase and then refinance into a full development facility once planning consent is secured.

Developer Money Market's bridging finance service connects developers with a large panel of specialist lenders offering fast decisions and competitive terms from 0.65% per month.

Development Exit Finance

Development exit finance is a short-term loan designed for developers who have completed or nearly completed a scheme but need additional time to sell units or arrange long-term refinancing. Typical loan terms run from 3 to 18 months. For multi-unit projects, this facility allows developers to repay a more expensive development loan while selling remaining units at full market value, rather than accepting discounted offers to meet facility deadlines.

LTV norms for mainstream residential exit facilities currently sit at around 70 to 75% of the completed scheme value. You can compare development exit finance lenders directly through Developer Money Market's online platform.
