The most common answer you'll hear is £50,000. Sometimes £100,000. Occasionally someone will tell you that you can start with less if you use the right financing. All of these are partially true — and none of them give you the full picture.
The honest answer is that it depends on three things: the type of project you're targeting, the finance product you're using, and what lenders will actually offer someone at your experience level. Let's work through each one.
What lenders actually care about
Most first-time developers assume the main question is how much they have in savings. Lenders care about that, but it's not the first thing they look at. Before they get to your capital, they want to understand your project type, your exit strategy, and whether you have any relevant experience — even professional experience that isn't directly property development.
This matters because it shapes what finance products are available to you, and therefore how far your capital actually stretches.
Bridging finance changes the maths
If you're buying a property to refurbish and sell — what most people call a flip — bridging finance is typically the right product. A bridging lender will usually advance up to 70% of the purchase price for a first-time developer, which means you need to provide the remaining 30% plus your build costs from your own capital.
On a £200,000 property with £50,000 of refurbishment work, that looks like this:
- Your deposit (30%): £60,000
- Build costs: £50,000
- Stamp duty (5% surcharge for additional dwelling): £10,000
- Legal, broker, and valuation fees: approximately £5,000
- Finance costs (bridging at ~0.95%/month over 9 months): approximately £16,000
Total capital required: around £141,000. The bridge covers the remaining £140,000 of the purchase price.
This is a simplified illustration. Your actual numbers will depend on lender criteria, project type, and experience level. The Corebal Buying Power module works through your specific situation properly.
What about smaller projects?
If £141,000 sounds like a lot, there are routes that require less capital. Smaller properties in lower-cost areas obviously change the numbers significantly. Some lenders will also consider joint ventures, where a more experienced partner contributes their track record in exchange for an equity split — which can unlock better terms and higher LTV ratios.
The key point is that your available capital doesn't determine whether you can do a deal. It determines which deals are accessible to you and on what terms. Understanding that distinction is what separates developers who find opportunities from those who assume they can't afford to start.
The number most guides miss
Almost every guide on property development startup costs forgets to mention contingency. Builds run over budget. Sales take longer than expected. Finance costs accumulate while you wait. A reasonable contingency buffer is 10-15% of total project costs — and if you're using bridging finance, every extra month adds meaningful cost.
If your numbers only work in the best-case scenario, they don't work.
So what's the real minimum?
For a modest first project — a cosmetic refurbishment of a property under £150,000 — you're looking at a minimum of around £60,000-£80,000 in accessible capital, including contingency. Below that, your options narrow considerably and the risk profile increases.
That doesn't mean it's impossible with less. It means you need to be precise about what's actually available to you before you start making offers.
