Many property investors spot promising development opportunities but feel held back by the capital requirements.
They assume they need hundreds of thousands upfront, watching prime sites slip away while established developers snap them up using funding structures most people don’t understand.
This knowledge gap costs money.
While some hesitate, others complete profitable projects using sophisticated financing that dramatically reduces personal equity requirements. Without understanding these options, potential developers either settle for smaller projects or miss opportunities entirely.
The property development capital stack offers a strategic solution. Rather than needing massive personal funds, you can combine different funding sources to tackle larger, more profitable projects while protecting your capital for future opportunities.
Understanding capital stack financing lets developers run multiple projects simultaneously, maximise returns on invested capital, and build substantial portfolios even with limited personal funds.
Let’s look at how it works, who benefits most, and how to structure your first development finance package.
How Capital Stacks Work
A capital stack works like building blocks – each layer represents different money sources for your project, combining to cover total costs without requiring enormous personal investment.
This approach exists because development projects need more money than most people have available, and banks won’t lend 100%.
Instead of finding £1.5 million yourself for that residential development, you might combine £1 million bank funding, £300,000 mezzanine finance, and £200,000 of your own money.
Each layer has its own distinct characteristics.
Bottom layers cost less but provide limited amounts. Higher layers cost more but fill gaps cheaper funding can’t cover. Different lenders have varying risk appetites and return expectations, making this layered approach work effectively.
Capital stacks have become increasingly popular in today’s market. They help optimise funding mix, potentially reducing overall costs while accessing more capital than any single lender would provide.
The repayment hierarchy follows “first in, first out” principles.
Senior debt gets repaid first, then mezzanine finance, then equity investors receive returns.
This order explains why costs vary – senior debt holders face lowest risk and charge less, while equity investors take highest risk but get highest potential returns.
Who Benefits From These Financing Structures
Capital stack financing isn’t exclusive to established developers.
Several types of people can leverage these structures effectively, often with less experience than they think necessary.
Property Investors
If you’ve built a successful buy-to-let portfolio, capital stacks help leverage existing success into development opportunities. Your property portfolio provides security for senior debt, while your track record demonstrates competence to lenders.
The transition becomes smoother when you’re not funding everything from savings. Capital stacks let you tackle first developments while keeping existing portfolios intact for future opportunities.
Business Owners
Successful business owners often have a good level of assets but limited liquid cash for large developments. Capital stacks let you use business success as security while accessing opportunities that might otherwise require selling assets or taking excessive personal risk.
Your business acumen transfers well – project management, cash flow understanding, and risk assessment provide valuable development skills that lenders recognise when combined with proper professional guidance.
First-Time Developers
Development experience isn’t essential if you have strong financial backing, valuable assets, or professional guarantors. Many successful developers started using capital stack financing, combining family support, business assets, or property security with professional lending.
The key is demonstrating financial stability, professional support, and clear project planning that gives lenders confidence, even without extensive development history.

Capital Stack Layers
Most developers get confused by the different funding options available, but once you understand what each layer does and costs, you can build a financing structure that maximises your borrowing power while minimising your personal risk.
Senior Debt
Senior debt forms the bedrock of most projects, representing bank lending secured against the property itself with a first legal charge.
This covers 60-75% of project costs at the most affordable rates because lenders hold first charge security.
Banks release funds in construction stages, protecting their investment while ensuring available money when needed. Applications focus on project viability, completion ability, and clear repayment strategies.
Specialist brokers add significant value through access to lenders who don’t deal directly with borrowers, application expertise that meets specific requirements, and negotiation skills that substantially improve terms.

Mezzanine Finance
Mezzanine finance tops up senior debt, allowing you to borrow more, reducing your personal equity requirements.
This secondary (subordinated) lending costs more than senior debt but offers flexible terms and can make the difference between projects proceeding or stalling.
Rather than property security, mezzanine finance often secures against project equity or other assets. This lets mezzanine lenders step in if problems arise, but higher risk means higher charges.
Complex applications require detailed projections and experienced presentation. Specialist brokers understand structuring requirements and which lenders suit different projects and borrower profiles.

Equity Investment
Equity investment comes in two distinct forms, each appealing to different investor types and offering varying risk-return profiles for your development projects.
Preferred Equity sits between debt and pure equity, offering investors fixed returns (usually 7-15% annually) plus priority over common equity holders when profits are distributed.
These investors get paid after all debt but before anyone else, making it lower risk than common equity while still offering upside potential through “equity kickers” if projects exceed expectations.
Preferred equity appeals to institutional investors, family offices, and conservative investors seeking predictable returns with some protection. For developers, it provides capital without giving up full ownership or unlimited profit sharing, though you’ll pay fixed returns regardless of project performance.
Common Equity represents true ownership stakes where investors share fully in both risks and rewards.
Common equity holders get paid last but have unlimited upside potential – if your development makes exceptional profits, they benefit proportionally.
This includes your own money (developers typically contribute 10-25% as common equity to show “skin in the game”) plus any partners taking pure ownership stakes. Common equity investors often want significant input into project decisions since they face the highest risk. Joint venture partners, private investors, and crowdfunding participants typically take common equity positions.
Joint Venture Structures can combine both types – perhaps preferred equity investors providing steady capital at fixed returns, while common equity partners (including yourself) share the remaining profits. This layered approach lets you access different investor types within a single project structure.
Finding the Right Mix depends on your capital needs and willingness to share control.
Preferred equity provides capital with less control dilution but fixed costs, while common equity shares risks and rewards more equally but gives investors greater say in project decisions.
The Right Structure
Professional structuring becomes essential when combining different equity types, as agreements must clearly define payment waterfalls, decision-making rights, and exit procedures.
Specialist finance brokers with extensive investor networks can facilitate introductions and help structure arrangements protecting everyone’s interests while optimising your capital access.
Smart Alternatives
Beyond standard capital stack layers, alternative approaches might better suit specific circumstances.
Joint venture partnerships let you team up with investors bringing capital and expertise, sharing profits through pre-agreed arrangements rather than paying fixed interest.
Crowdfunding platforms and peer-to-peer lending open new capital sources, particularly for smaller projects or developers building track records. These complement traditional funding or provide complete solutions for certain developments.
Forward funding involves selling developments to investors before construction starts, with staged payments during building. This transfers development risk to buyers while providing guaranteed exit and construction cash flow.
Family office networks and private investor groups offer development funding with patient capital and expertise alongside financial contributions. These relationships often develop into long-term partnerships across multiple projects as trust and track records establish.
Bridging Finance
Bridging loans provide rapid capital access for specific phases or unexpected opportunities. These short-term facilities (3-24 months) cost more than long term lending but are flexible and quick to set up.
Use bridging finance to secure auction sites, cover construction cash flow gaps, or provide funding while arranging longer-term development finance. Speed and flexibility justify higher costs for experienced developers understanding when opportunities warrant premium pricing.
How Expert Finance Brokers Make a Difference
Development finance requires specialist expertise where broker knowledge can maximise a project’s success.
Brokers provide access to hundreds of lenders including private banks and wealthy individuals who don’t deal directly with borrowers, dramatically expanding options beyond high street banks.
Capital stack structuring demands detailed understanding of different lenders’ criteria, preferences, and processes.
Experienced brokers know which lenders work well together, how to present applications meeting specific requirements, and negotiation approaches that optimise funding packages.
Time matters enormously in development and brokers arrange funding faster than direct approaches, handle multiple applications simultaneously, and provide ongoing project lifecycle support.
Getting Started
Before approaching lenders or brokers, gather together your essential project information.
You’ll need site details, planning permission status, construction costs, sales projections, and personal financial positions. Ready information demonstrates professionalism and speeds assessments.
Consider experience levels honestly and identify areas needing professional support. First-time developers benefit from engaging quantity surveyors, project managers, and experienced solicitors understanding development finance requirements.
Development funding processes usually take several weeks, even with specialist support. Planning permission, detailed costings, and legal work take time, so start early avoiding delays that could jeopardise opportunities or increase costs.
Next Steps
Capital stack financing transforms property development into an accessible opportunity for investors with varying capital and experience levels.
Strategic funding source combinations let you undertake larger projects, reduce personal risk, and achieve better returns on invested capital.
Success comes from understanding that development finance involves more than borrowing money – it’s about structuring packages that optimise resources while managing risk effectively.
Whether you’re scaling up from property investment, diversifying from business success, or pursuing development ambitions with limited capital, capital stack financing could unlock previously unreachable opportunities.

FAQ
A capital stack is a combination of different funding sources layered together to finance your development project. Think of it like building blocks – you combine bank loans, mezzanine finance, and equity investment to cover total project costs in addition to your personal investment.
Yes, though you’ll need strong financial backing, valuable assets for security, or experienced guarantors. Many first-time developers successfully use capital stacks by demonstrating financial stability and clear project planning even without development history.
Senior debt is cheaper bank lending (first priority for repayment) covering 60-75% of costs. Mezzanine finance is more expensive secondary lending that tops up senior debt, reducing your equity requirement but costing more due to higher risk.
While not always essential, having planning permission significantly improves your chances and available loan amounts. Lenders prefer the reduced risk of approved schemes over speculative applications.
Senior lenders take first charge over the development property. Additional security might include other properties, business assets, or personal guarantees depending on loan amount and your financial profile.
Absolutely. Capital stacks work well for offices, retail, industrial, and mixed-use projects. Commercial developments often attract sophisticated investors willing to participate in structured funding arrangements.
