How to get 100% development finance

Securing 100% development finance can be possible, but it’s rarely a straightforward “no deposit” option from mainstream lenders. In many cases, the structure is closer to joint venture development finance, where the lender funds the development costs and takes a share of the upside in return for taking on significant risk.

This guide explains what 100% development finance usually involves, what typically makes an application more credible, and the alternatives that may help if you have limited or no deposit.

Can development finance cover 100% of construction costs?

Sometimes, yes—depending on the project, the developer, and the lender/investor’s appetite for risk. Where 100% funding is considered, it is commonly arranged on a bespoke basis, meaning the terms, profit split, and risk protections can vary.

In practice, “100% development finance” and joint venture development finance are often used to describe similar concepts.

What joint venture development finance means

With joint venture development finance, the lender and developer effectively enter a partnership for the project:

• The lender agrees to fund the development costs.
• The lender’s return is typically linked to the profit outcome once the scheme completes.
• The developer remains responsible for delivery, while the lender may require involvement/controls to manage risk.

The profit share is often discussed as a 50/50 split, but it can be structured differently. Some arrangements may include rolled-up interest alongside a reduced profit share, or other bespoke commercial terms.

Why lenders focus on the project’s “numbers”

Because the lender is funding the full cost, they will usually want strong confidence in:

• the gross development value (GDV)
• the viability of the scheme
• the ability to deliver the project to completion
• the exit route (how the capital is repaid)

In general, lenders/investors may prefer projects with clear assumptions, credible delivery plans, and an appropriate level of experience.

Will 100% development finance be possible with no experience?

It’s possible, but it’s much harder.

When a lender is funding 100% of costs, they are taking on a higher level of risk than in a more traditional development arrangement where the developer has more “skin in the game”. Without a proven track record, lenders may struggle to justify why the project will be delivered successfully.

If you’re early in your development journey, you may need to strengthen other areas, such as:

• the quality and realism of your business case
• evidence of competence through team capability (for example, proven project management or delivery partners)
• clear, credible planning and delivery milestones
• a robust exit plan and risk controls

In many cases, this is where specialist structuring and advice can be important.

How to improve your chances of getting 100% development finance

Getting to “100%” usually requires more than asking for a higher loan-to-cost figure. It means presenting a project that looks deliverable, measurable, and well controlled.

1) Build a lender-ready business case

A strong application typically includes a clear narrative and supporting evidence showing:

• your relevant experience (or how the project team reduces delivery risk)
• why the scheme is viable and how profit is expected to be generated
• how costs are controlled and what happens if assumptions change

A lender will also want to understand the exit—how the development will be completed and how the lender will be repaid or realise their return.

2) Have your planning position in place

Many joint venture structures require planning permission (or at least a clearly defined planning route with appropriate certainty) before the lender commits to funding.

If planning is not yet agreed, the lender may be reluctant to take on the risk of delays or changes. That can mean you may need to fund planning activity yourself before the main development finance is considered.

3) Demonstrate a credible delivery plan

Because the lender is funding the full development cost, they will look for confidence in execution, including:

• realistic build timelines
• procurement and contractor arrangements
• how variations and cost increases would be managed
• what controls are in place to keep the project on track

4) Understand how risk is shared

In 100% development finance, the lender’s return is often tied to outcomes, but the lender may also seek protections such as:

• governance or oversight during the project
• conditions around drawdown and milestones
• additional security arrangements where appropriate

The more clearly you can explain how risk is managed, the more credible your proposal tends to look.

Will you get better terms if you can add a deposit?

In general, reducing the amount you need to borrow can improve the risk profile of a development proposal. While 100% funding may be available in some cases, adding a deposit can sometimes make it easier to secure more competitive terms because the lender’s exposure is lower.

That said, the “best” structure depends on the project, the funding mix, and the commercial position of both parties.

Which lenders offer 100% development finance?

100% development finance is typically not something you’ll find through standard high-street channels. It is often arranged by lenders/investors who specialise in development risk and are comfortable with bespoke structures.

Because these deals are frequently tailored, it can be difficult to compare offers using simple headline metrics. The key is to compare the overall commercial package, including how the lender’s return is calculated and what protections are included.

Other ways to fund a development if you have limited or no deposit

If 100% funding isn’t available for your specific circumstances, there are alternative approaches that may help bridge the deposit gap.

Private investment

Some developers attract private capital to cover part of the funding requirement—sometimes specifically the deposit element—either for the whole scheme or alongside other finance.

Equity release from existing property

If you have property holdings, releasing equity through refinancing can sometimes provide the cash needed for a deposit.

Use existing assets as additional security

Where appropriate, offering additional security from existing assets may help reduce perceived risk for lenders, potentially improving the feasibility of a development finance package.

What to expect from a specialist development finance process

A specialist approach usually focuses on matching the right structure to the project:

• assessing the viability of the scheme and the exit
• understanding the lender’s risk appetite and preferred structures
• preparing the documentation needed for underwriting
• considering whether 100% funding is realistic or whether a blended approach is more suitable

Even where 100% development finance is the goal, the process often starts with evaluating what the lender will need to see to justify the risk.

Summary

100% development finance is often structured as joint venture development finance, where the lender funds the full development cost and takes a return linked to the project’s outcome. To improve your chances, focus on a robust business case, planning certainty, credible delivery plans, and a clear exit strategy. If 100% isn’t achievable, alternative funding routes—such as private investment, equity release, or additional security—may help you move forward with a workable structure.
