Funding a multi-unit development in the UK requires a different approach to financing a single dwelling. Whether you are building a block of flats, converting a commercial building into apartments, or phasing a larger residential scheme, the finance structure you choose will directly affect your profit margin, cash flow, and ability to scale. With lenders in 2026 actively funding multi-unit freehold blocks, HMOs, and mixed-use conversions, developers have more options than ever. This guide walks you through the best development finance options available for multi-unit projects and explains how to pick the right one for your scheme.

What Is Multi-Unit Development Finance?

Multi-unit development finance is a short-term funding solution designed to cover the purchase and construction costs of projects delivering two or more residential or commercial units. Unlike a standard mortgage, property development finance is assessed against the Gross Development Value (GDV), which is the estimated open market value of the completed scheme once all units are finished and ready for sale or letting.

Finance is typically drawn down in stages as the build progresses, with interest rolled up and repaid on completion or as units sell. On multi-unit schemes, the outstanding debt reduces with each completed unit sale, which means your finance costs actively decrease as you sell through the development.

Senior Development Finance (Senior Debt)

Senior debt is the foundation of most multi-unit funding structures. It is a first-charge loan secured against the development site and typically covers land acquisition, construction costs, and professional fees. Most lenders cap borrowing at 60 to 70% of GDV and up to 85 to 90% of total project costs.

Developer Money Market provides access to over 320 loan products from more than 120 specialist lenders, making it straightforward to compare senior debt options for your multi-unit project. Facilities range from £25,000 to £50 million, covering projects across England, Scotland, Wales, and Northern Ireland.

Typical Senior Debt Parameters in 2026

Rates in 2026 for residential ground-up schemes by established developers typically sit between 0.65% and 0.90% per month. Less experienced developers or higher-leverage deals may see rates above 1.10% per month.

Stretch Finance for Higher Leverage

Development stretch funding is a finance structure that combines both senior debt and mezzanine funding into one facility from a single lender. For multi-unit developers, this removes the complexity of managing two separate lenders and avoids inter-lender agreements.

A stretch facility can cover up to 90% of total costs, and sometimes even 100% where the developer offers alternative security. This allows you to spread capital across a larger number of projects or take on more ambitious multi-unit schemes. Loan sizes typically range from £500,000 to £100 million with terms of 12 months to 3 years.

Mezzanine Funding to Bridge the Equity Gap

Mezzanine finance is a second-charge loan that sits behind senior debt to fill the gap between what the bank will lend and the total project cost. It is an effective tool for multi-unit developers who want to preserve cash for future projects or who lack sufficient equity for a particular scheme.

When considering how to raise mezzanine funding, be aware that rates are higher, typically 15% to 24% per annum, reflecting the lender's increased risk with a second charge. Most providers will expect you to demonstrate a successful track record in property development and contribute at least 10% of build costs as equity.

100% Joint Venture (JV) Finance

Joint venture development finance is a funding structure where the lender provides up to 100% of acquisition, build, and professional costs. The developer contributes expertise rather than capital. In return, profits are shared, often on a 50:50 basis.

This option suits experienced developers whose equity is tied up in other projects but who have identified a strong multi-unit opportunity. Facilities between £500,000 and £4 million are the most common, although funding up to £20 million is possible. Borrowers need a proven track record and the ability to demonstrate successful delivery of similar schemes.

Bridging Finance and Development Exit Finance

Bridging finance is a short-term loan used to secure a site quickly, often before planning consent is achieved. Development bridging finance enables developers to respond fast to competitive opportunities. Terms typically range from 3 to 12 months with rates from around 0.65% per month.

Development Exit Finance

Development exit finance is a bridging loan used to repay the original development facility once a scheme is complete or near-complete, giving you additional time to sell units at the best price. In early 2026, indicative rates for lower-risk residential exit loans start from around 0.6% per month, with LTV norms of 70% to 75% for mainstream residential schemes. This product is especially valuable on multi-unit projects where phased sales can extend beyond the original loan term.

Phased Finance for Larger Multi-Unit Schemes

For developments of 30 or more units, phased finance is standard practice. Phased development is the strategy of dividing a large construction project into distinct stages, each of which can be built, completed, and sold before the next begins. This approach limits maximum lender exposure at any point and creates opportunities for capital recycling.

For example, a 60-unit scheme with an £18 million GDV could require an £11 to £12 million facility if built in a single phase. By dividing into three phases of 20 units, each phase needs only approximately £3.5 to £4 million, opening the deal to a wider range of lenders and significantly reducing upfront equity requirements.

Single Facility vs. Separate Facilities

For schemes of 30 to 60 units over two or three phases, a single facility with phased drawdowns is usually most efficient. For larger schemes of 60-plus units over three or more phases, separate facilities are more common due to extended timelines of four to six years.

Frequently Asked Questions

What is development finance for multi-unit projects?

Development finance for multi-unit projects is a short-term loan, typically 12 to 36 months, designed to cover the land purchase, construction, and professional fees for building two or more residential or commercial units. It is assessed against the Gross Development Value rather than current site value.

How much deposit do I need for a multi-unit development loan?

Most lenders require a minimum of 10% to 15% of total project costs as equity. The day one land deposit is usually 30% to 40% of the site purchase price, with construction costs funded through staged drawdowns.

Can I get 100% funding for a multi-unit development?

Yes. Joint venture finance can cover up to 100% of acquisition, build, and professional costs. However, you will need a strong track record of completing similar projects and will typically share profits with the JV lender on a 50:50 basis.

What interest rates should I expect in 2026?

Senior development finance rates in 2026 typically range from 0.65% to 1.10% per month (approximately 8% to 13% per annum). Experienced developers on lower-leverage deals can achieve rates at the lower end of this range.

What is the difference between stretch finance and mezzanine finance?

Stretch finance combines senior debt and mezzanine into a single facility from one lender, covering up to 90% of costs. Mezzanine finance is a separate second-charge loan from a different lender that tops up senior debt, typically at higher interest rates.

How does phased finance work for larger developments?

Phased finance divides a large scheme into stages. Each phase is funded separately or through phased drawdowns within a single facility. Sales proceeds from completed phases can be recycled to fund equity on subsequent phases, reducing the total capital required.

Do I need planning permission before applying for development finance?

Not always. Some lenders, particularly bridging providers, will lend before planning is granted, subject to acceptable security. However, having planning permission in place will significantly improve your terms and widen the pool of available lenders.
