Choosing the right development finance option is one of the most important decisions you make when planning a property project. The funding you secure influences how quickly the development moves forward, how much flexibility you have, and how well your financial structure supports the entire build. Development finance is designed to help you purchase land, fund construction work, manage cash flow, and complete the project without unnecessary delays, but every product works differently and suits different project types.
Understanding how each option works helps you avoid borrowing in a way that holds the project back or creates pressure later. This guide breaks down the main forms of development finance, explains how they differ, and shows how to evaluate which funding route fits your goals.
What is development finance designed for?
Development finance is short to medium term funding that supports property construction and refurbishment. Developers, investors, and businesses use it to complete projects that traditional mortgages cannot fund.
Common uses include:
- Ground up residential developments
- Commercial to residential conversions
- Heavy or structural refurbishments
- Light refurbishments
- Property extensions
- Purchasing land with planning permission
- Strengthening cash flow during multi-phase projects
Development finance lends against the project’s value once completed, allowing borrowers to secure more funding than they could with a standard mortgage. It is designed to fund construction costs as the project progresses, making it essential for developments that need staged releases of capital.
Senior development finance
Senior development finance is the primary type of funding used for most projects. It covers a large portion of the land or property acquisition and provides staged drawdowns for the build.
Senior debt typically offers:
- Loan to gross development value of around 60 to 70 percent
- Loan to cost percentages that support most of the budget
- Interest charged monthly or rolled up
- Funds released in stages as work is completed
- Terms that match the construction timeline
This type of finance is suitable for experienced developers as well as first time developers with a strong plan, solid costings, and professional support. Senior lenders want reassurance that the project is viable, achievable within the timeframe, and backed by a realistic exit strategy.
Stretched senior development finance
Stretched senior development finance offers higher leverage than traditional senior debt. It combines features of senior debt and mezzanine finance by providing an increased loan to cost or loan to GDV percentage under a single facility.
Typical features include:
- Higher loan to GDV than standard senior debt
- Increased loan to cost
- A single lender structure
- More flexibility for developers who want fewer funding layers
- Higher interest rates than traditional senior finance
Stretched senior finance works well for developers who want to reduce their upfront capital contribution or maintain cash flow for additional projects. It is also beneficial for those who prefer a simpler funding structure without separate mezzanine agreements.
Mezzanine finance
Mezzanine finance is a secondary funding layer that sits behind the senior loan. It is used when the developer needs additional capital beyond what senior lenders will offer.
Mezzanine funding is typically used for:
- Raising extra capital for acquisition
- Supporting higher loan to cost percentages
- Reducing the developer’s cash input
- Funding larger or more ambitious projects
It provides higher leverage but comes with higher interest rates because the lender takes on more risk. Mezzanine finance can be an effective tool for developers who want to scale projects or retain capital for future opportunities.
However, lenders will want reassurance that the senior lender is supportive and that the overall project structure is workable.
Equity finance
Equity financing is when an investor contributes capital to a project in exchange for a share of the profits. Instead of borrowing additional funds, the developer reduces their financial contribution by sharing future returns.
Equity partners may be used for:
- High value projects
- Developers who want to reduce their exposure
- Projects with strong profit potential
- Schemes that require expertise or joint venture support
Equity is not a loan, so there are no monthly repayments, but it does reduce the developer’s share of final profits. This structure works well for developers who are comfortable sharing returns in exchange for financial support or additional expertise.
Light refurbishment finance
Light refurb projects typically include:
- Cosmetic improvements
- New kitchens or bathrooms
- Modernisation
- Decoration
- Flooring
- Minor layout changes
Funding is usually quicker and simpler than full development finance, and lenders focus more on costings, timelines, and end value than on complex assessments.
Light refurbishment finance covers smaller projects that do not require structural work or planning permission. This type of finance is popular with investors and landlords improving rental stock or refreshing properties before resale.
Heavy refurbishment finance
Projects involving structural changes, extensions, conversions, or obtaining planning permission typically require heavy refurbishment finance. These projects require more detailed assessments, higher budgets, and longer timelines.
Examples include:
- Structural alterations
- Loft conversions
- Side or rear extensions
- Commercial to residential conversions
- Major internal reconfigurations
Lenders focus heavily on costings, schedule of works, planning documents, and professional involvement. Heavy refurb finance bridges the gap between simple refurbishments and full ground up development.

How lenders assess development finance applications
To choose the right option, it is important to understand how lenders review development projects. Their requirements help you match the correct funding structure for your development.
Lenders typically assess:
- Experience and track record
- Gross development value
- Loan to cost figures
- Strength of the contractor team
- Schedule of works
- Planning permission or permitted development rights
- Market demand for the finished units
- Exit strategy
Clear documentation and realistic projections play a major role in securing the right development facility.
Exit strategies and why they matter
Every development finance option requires a clear and achievable exit strategy. Lenders want reassurance that the loan will be repaid within the agreed timeframe.
Common exit routes include:
- Selling completed units
- Refinancing onto a buy to let or commercial mortgage
- Selling part of the site
- Long term rental income
- Refurbish and refinance strategies
A strong exit strategy helps determine whether you need senior debt, stretched senior, mezzanine, or a combination of funding types.
How to evaluate which development finance option is right for your project
Choosing the correct option depends on several factors. The right structure supports your cash flow, reduces pressure during the build, and helps you complete the project smoothly.
Key points to consider include:
1. Project scale and complexity
Large or structurally complex projects often require senior debt combined with mezzanine or equity.
2. Your available capital
If you want to reduce your contribution, stretched senior or mezzanine finance may be appropriate.
3. Risk appetite
Higher leverage options increase financial exposure but offer greater flexibility.
4. Build timeline
Shorter projects may suit light refurb finance, while longer schemes need structured development facilities.
5. Experience level
Experienced developers may access more competitive rates and higher leverage.
6. Property condition
Light refurb and development finance differ significantly depending on the level of structural work.
7. Planning position
Projects needing planning permission may require additional checks or staged releases.
Final thoughts
Choosing the right development finance option depends on the project’s size, complexity, timeline, and profit potential. Understanding how senior debt, stretched senior, mezzanine finance, equity investment, and refurbishment facilities work allows you to structure your development with confidence and clarity. With realistic costings, a strong team, and a clear exit strategy, your project stands the best chance of progressing smoothly and achieving its goals.
