Property development finance is the funding that turns a plot or a tired building into finished, saleable units. You have found a site with real potential: a plot with planning, or a tired building crying out for conversion. The plan is sound, the numbers stack up, and then you try to fund it. A normal mortgage takes one look at a building that does not exist yet and politely declines. Your own cash covers the deposit and not much else. What you need is development finance, and it works nothing like the lending you used to buy your house.
Development finance is short-term funding built specifically for building. Instead of handing over a lump sum against a property that already exists, the lender funds the land and then releases the build cost in stages as the work goes up. It is designed around how a project actually behaves, where value is created brick by brick and the money needs to turn up in step with it, not all at once on day one.
Here is how development finance works, stage by stage, what decides how much you can borrow, why schemes get turned down, and what lenders want to see before they back you.
What Is Development Finance?
Development finance is a short-term facility that funds the purchase of a site and the cost of building or converting it. The term usually runs the length of the project plus a window to sell or refinance, often twelve to twenty-four months.
What it actually funds
A development facility typically covers a large slice of the land and the majority of the build costs. It is for ground-up new builds, conversions and heavy refurbishments, the kind of scheme that changes what a building is, not just how it looks. If all you are doing is a light refresh, this is more firepower than you need.
How it differs from a mortgage or a bridge
A mortgage wants a finished, habitable property. A bridge funds a quick purchase or a lighter project. Development finance sits beyond both, funding work that genuinely increases the value of the site and releasing the money in stages rather than in one nervous lump. Plenty of developers use a bridge to grab the land quickly, then move onto a development facility for the build itself.
Who it is for
Developers, investors and builders, from seasoned operators juggling several sites to first-timers with a strong scheme and the right people around them. The common thread is a project that adds value and a clear plan for the day it is finished.
How Development Finance Works, Stage by Stage
The defining feature of development finance is staged funding. The money is not one payment. It is a series of releases tied to progress on site.
Stage one, the land
The lender advances a portion of the purchase price of the site, with you putting in equity alongside it. That gets the plot bought and the project off the ground.
Stage two, staged drawdowns for the build
As the build hits agreed milestones, the lender releases the funds for that phase. A monitoring surveyor usually inspects the site before each release, confirming the work is done and the money is going where it should rather than on a nicer van. It sounds like box-ticking, but it protects your budget as much as the lender’s.
Stage three, interest and fees
Interest is usually rolled up rather than paid monthly, which protects your cash flow while the site earns nothing. There are arrangement and exit fees too, because there always are. Judge the cost across the whole facility, not on the headline rate.
How Much Can You Borrow? GDV, LTC and LTGDV
Development lending has its own alphabet, and understanding it is the difference between a realistic plan and a stalled one.
Loan to cost (LTC)
This measures the loan against the total cost of the project, land plus build. Lenders often fund up to around 70% to 80% of total costs, with you covering the rest. The more you put in, the calmer the lender.
Loan to gross development value (LTGDV)
This measures the loan against the finished value of the completed scheme, the gross development value. Lenders usually cap the whole facility at around 65% to 70% of GDV, which sets a ceiling regardless of what the build costs.
The equity you need to bring
Between those two limits, expect to contribute a meaningful chunk, commonly 20% to 35% of costs. Picture a scheme costing £800,000 to build out with a finished value of £1.2 million. A lender might fund 75% of cost, so £600,000, and check that figure sits comfortably under 65% of the £1.2 million value. You bring the balance. Experience and a credible exit improve the terms, which is the polite way of saying a good case is cheaper than a shaky one.
Why Do Development Finance Applications Get Declined?
Most refusals are avoidable, and they tend to come down to the same handful of things.
The numbers do not stack
If the build costs are optimistic or the GDV is punchy, the lender sees straight through it, because they value the finished scheme independently. A realistic appraisal beats a flattering one every time, since the flattering one falls apart at valuation anyway.
The exit is vague
“We will sell them” is not an exit, it is a hope. Lenders want to know who buys or refinances the units, at what value, and how quickly. A clear plan to sell or to refinance onto a buy-to-let or commercial mortgage is what gets a scheme over the line.
The team is thin
A first-time developer with no experienced contractor and no professional team makes a lender nervous. You do not need a decade of sites behind you, but you do need the right people around you, and a case that shows you know what the build involves.
The Clever Way to Fund Your Build
Development finance is a genuinely different animal, built around the way a project actually unfolds: buy the land, draw down in stages, build the value, then sell or refinance. Get the appraisal right, bring a sensible amount of equity and line up a credible exit, and a good scheme will usually find funding, whether it is your first site or your fiftieth.
The hard part is presenting it the way a development lender wants to see it, and matching it to the right funder for your kind of project. That is the heavy lifting we do. Send us the scheme and the numbers, we will tell you straight where you stand, then package and place your development finance so the money turns up in step with the build. Do the Clever thing.
Frequently Asked Questions
In stages, tied to build progress rather than in one lump sum. The land portion is advanced at the start, then the build cost is released in tranches as each phase completes. A monitoring surveyor usually signs off each stage before the money is drawn, which keeps the scheme funded in line with the work actually done on site rather than the work you hoped to have done.
Yes, though the bar sits higher. A first-timer with a strong, well-costed scheme, an experienced contractor and a clear exit can secure funding, often at a slightly lower loan-to-cost or a rate that reflects the extra risk. Surrounding yourself with an experienced team is the single biggest thing that settles a lender’s nerves.
The exit is how you repay the facility once the scheme is finished, and it is usually one of two routes. You either sell the completed units and redeem the loan from the proceeds, or you refinance onto a longer-term product such as a buy-to-let or commercial mortgage and keep the asset. If sales are slow, a development exit facility can bridge the gap while you sell or let, rather than forcing a fire sale.
Typically four to eight weeks, depending on how complex the scheme is and how ready your paperwork is. Planning permission, a costed schedule of works and details of your team all speed things up. Since timing usually matters when you are trying to secure a site, getting the appraisal in order early is effort well spent.
