How Do Development Finance Loans Work?

Development finance can often feel like a bit of a black box. For seasoned developers, it might be familiar territory, but for those newer to the industry or stepping into larger projects, understanding how development finance loans work is crucial. In this article, we’ll explore how these loans function, who they’re for and what you need to consider when exploring development finance as a funding option.

 

What is Development Finance?

Development finance is a form of short-term lending designed specifically for property development projects. These loans provide developers and their partners with the capital required to purchase land and fund construction costs. Once the development is complete and sold or refinanced, the loan is then repaid, leaving the developer with the profit margin from the project after accounting for all development costs, interest, and fees. A key point on the product is that interest is typically rolled up and paid out from sales at the end of the project

Unlike traditional mortgages or commercial loans, development finance is structured around the build schedule and is usually released in stages rather than as a lump sum. This staggered funding approach is referred to as ‘drawdown’, and aligns the financing with specific construction milestones, allowing lenders to manage risk.

 

Types of Development Finance Loans

Development finance is not a one-size-fits-all funding solution. There are actually several types of development finance loans available depending on the nature and scale of the project.

 

Commercial Development Loans

Commercial development finance loans are tailored for the construction or redevelopment of business premises such as office buildings, retail spaces and industrial units. They focus on commercial viability, tenant demand and income yield.

 

Residential Development Loans

Aimed at developers looking to build new homes, flats and other residential-led mixed-used schemes, residential development finance is an extremely popular financing option in the UK. To determine viability, lenders will typically assess factors such as end-user demand, local market conditions and potential sales velocity.

 

Ground-Up Development Loans

As the name would suggest, this funding option is suitable for projects starting from scratch, such as building residential units on vacant and unowned land. Lenders will assess planning permission, construction costings, timelines and the project end value before releasing funds to developers enquiring on this type of project.

 

Refurbishment Loans

Refurbishment loans finance property upgrades, from minor renovations (known as light refurbishments) to major structural changes (known as heavy refurbishments). This funding solution is ideal for developers converting single homes into apartments or transforming outdated commercial spaces.

 

Bridging Loans

While not exclusively development finance, bridging loans can be used as a short-term funding option when timing is critical such as securing a property at auction, preventing a sale falling through, or taking advantage of time-sensitive opportunities before traditional financing can be arranged.

 

Stretch Senior Loans

Stretch senior development finance loans combine elements of senior debt and mezzanine finance to increase the total loan amount. They are ideal for experienced developers needing higher leverage but wishing to avoid layering multiple funding options.

 

Mezzanine Finance

Mezzanine finance fills the gap between primary loans and developer funds. It’s secondary debt, repaid after the main lender, with higher interest reflecting increased risk. This flexible funding enables developers to tackle larger projects without sacrificing more equity or cash reserves.

 

How Do You Obtain Development Finance?

The process of securing development finance is more bespoke and involved than applying for a high street mortgage. With higher risks and larger sums at stake, lenders conduct thorough due diligence and assess each project’s unique characteristics.

  1. Project proposal – You will need a detailed development plan including drawings, planning permissions and costings.
  2. Valuation and due diligence – The lender will commission independent valuations and assess the gross development value (GDV) of the project.
  3. Loan structuring – Funds are then released in tranches, aligned with each stage of the build.
  4. Legal work and drawdown – Once everything is agreed between lender and developer, funds are to be released as each phase is completed and certified.

 

Criteria for Loan Approval

Each lender is unique when it comes to criteria, and will assess applications based on their risk appetite, specialisations and internal policies. Understanding these variations in lending can be crucial when selecting the right financial partner for your project, but in general considerations include:

  • Developer experience – Previous track record and ability to manage a build project
  • Planning permission – Full planning consent is usually required before funds can be released
  • Loan-to-GDV ratio – Most lenders will lend up to a certain percentage of the projected GDV, typically 65 – 70%.
  • Loan-to-Cost ratio – This assesses how much of the project’s cost the loan will cover – usually up to 85%

 

Risk Assessment and Management

Lenders will conduct detailed risk assessments to ensure the viability of both the project and the developer’s ability to complete it successfully. Factors include market demand, the reliability of the build team, project timelines and potential exit strategies. Developers must also prepare for unexpected delays or cost overruns.

To mitigate risk, lenders often require step-in rights (to take over the project if things go wrong), personal guarantees, and independent monitoring surveyor (IMS) reports throughout the construction process to verify progress and quality before releasing staged payments.

 

Development Finance vs Traditional Lending

Unlike traditional bank lending, development finance is designed to be flexible and project-specific. High street lenders typically shy away from speculative builds, whereas development lenders understand the nuances and risks.

Traditional loans are also more rigid, often requiring full security upfront, fixed repayments, and are rarely suitable for phased developments. Development finance is typically more expensive, but it offers much-needed flexibility and speed.

 

When is Development Finance Suitable?

Development finance is suitable in a wide range of instances compared to traditional lending, with the most common scenarios being:

  • Developers have secured a site with or without planning permission
  • The project requires a substantial upfront investment in stages
  • There is a clear exit strategy (sale or refinance)

 

It is less suitable if:

  • Developers lack experience or planning permission
  • Developers have insufficient equity to contribute to the project
  • The development timeframe is long and uncertain

 

Importance of an Exit Strategy When Applying for Development Finance

Lenders will want a clear, well-documented plan for how the loan will be repaid, backed by credible market analysis and contingency options. This typically falls into two primary categories:

  • Sale of Units – Common in residential developments where individual properties are marketed and sold to homebuyers, generating capital to repay the loan
  • Refinancing – Often used for rental portfolios or longer-term investment properties, transitioning from development finance to a commercial mortgage once the project achieves stabilised occupancy

The exit strategy must be realistic and supported by robust market evidence, with particular attention to comparable sales, absorption rates and the projected timeline to full repayment.

 

Final Thoughts

Development finance loans are essential tools for property developers aiming to deliver housing, commercial or mixed-use schemes. While the process can be complex, understanding how it works – from loan types to approval criteria and risk management – helps ensure successful outcomes.

    WHAT OUR CUSTOMERS SAY ABOUT US

    "A challenging site like no other with every inch of the plot being built on and 12 apartments built-out through a driveway 2.5m wide off of a main high street with limited access rights, not to mention all the complexities associated with 13 Party Wall Agreements. Most lenders would not have had the vision for the scheme or the confidence in Spiller Builders to build out the scheme.  I just wanted to say how helpful the entire BLG team have been during the build. A very approachable and knowledgeable team, with a “can do” approach to lending. We will be looking to do more business with you for sure."

    “We have used BLG for development finance for over 8 years. During that time we have found their knowledge and expertise in the property development industry to be second to none. Their loan process, pragmatic and flexible approach to lending and flexibility when required has supported our business needs throughout the period and provided us with support to deliver new homes in Bristol and the surrounding areas.”

    “As property developers you never know the curve balls that you may get and a project that is great on paper may prove a bit more tricky.  This happened to us on a project that BLG have funded and throughout they have supported us.  Our business likes to be collaborative and when we hit those tough moments it really felt like we were working as a team with BLG.  If you have a decent project you can get it funded, but what you really need is a business that is there to support and advise you as well.  For us on this project it was BLG.”

    “I approached BLG Development finance with an opportunity I had in Chesham, Buckinghamshire, to build 5 new build houses in 2021. My main contact was Anil Bains who is a Director covering Asset Management. Within very quick timescales, BLG provided me with indicative quotes in regards the finance levels they could offer me. Having considered those levels, I requested a valuation to be carried out which again was dealt with swiftly. We proceeded to completion. The build went very smoothly with monthly monitoring being carried out by BLG and monthly drawdown requests dealt with in a very timely manner. Due to a difficult time generally in the market in regards selling, I was in need of a six-month extension to the loan which again was appraised very quickly and granted. Having dealt with numerous funders over the last 20 years, I can only speak highly of my personal experience with BLG and would very confidently work with them again on any future projects. “

    "From our side it has also been a pleasure working with BLG and the team there. We have found you easy to deal with, proactive in resolving any minor issues that have arisen through the project and shown great flexibility in working with us as a partner. We will certainly like to work with you on future partners."

    “I really appreciate your hard work. We really like the way you communicate & I must say I haven't seen many people who are that approachable.”

    “A very efficient processing team, dealing with the DD once deal credit approved, through to completion”

    “Many thanks for your efforts on this one and getting it approved and sorted so swiftly, very much appreciated. I am sure I will be speaking to your over the coming months.”

    “We had other funding options, but chose to use BLG again, as we work well with the team, who always provide very clear information and advice with a friendly approach throughout the funding process. Very efficient and always very helpful.”

    “Many thanks Anil, it’s been a real pleasure working with BLG so far.  We’re lining up the next project too”

    “We would recommend all staff we have dealt with at BLG, as we are very satisfied with the team and the initial offer/terms presented, then you and the funding team, through to the draw down team at valuation stage.”

    “All documents are clear and the way you keep clients informed, all the way along the funding process, is refreshing for us”

    “With regard to what should be improved at BLG, we work with many lenders in our business and we do not get the help and response we have had on the two projects with all at BLG on our funding for our developments.”

    “We would particularly mention Dave Edwards and Tom Pitts as being central to having a smooth working relationship and being positive and helpful at all times. Their guidance in helping us navigate the project from inception to completion was invaluable. As was their patience, particularly at the beginning. We look forward to many future projects with the BLG team.”

    “We would like to express our appreciation for your support on our development in Bristol. We were very pleased that, from the outset, you shared our vision of the project to convert a dated but classical building, that had outlived its usefulness as a school, into unique luxury apartments with views overlooking the city. We found our dealings practical and streamlined. Monthly payments were processed in an efficient and timely manner.”

    “BLG are very good at communicating with clients and all documents are very clear and all at BLG are always happy to help.”
