Why the Money Comes Before the Builders

Every successful development begins long before the first skip arrives on site. The single most common reason projects stall isn't planning permission or a shortage of trades — it's finance. Whether you're converting a tired Victorian terrace into two flats or building four new homes on a disused garage plot, you need to know exactly how the money will work before you exchange contracts on the land.

In the UK, there's no single "developer loan". Instead, there's a spectrum of funding options, each suited to a different stage, timescale and risk profile. Understanding how they differ — and what lenders actually look at — will save you weeks of fruitless applications and, quite possibly, your deposit.

Bridging Loans: Speed Over Everything

A bridging loan is short-term finance, typically arranged for three to eighteen months, designed to solve a timing problem. You've found the perfect auction lot but your existing property hasn't sold. Or you need to complete on a site quickly to beat a rival bidder. Bridging does the job, but it isn't cheap.

Expect interest rates that look startling next to a standard mortgage, plus arrangement fees, exit fees and often a monthly servicing charge or rolled-up interest. Lenders usually cap lending at around 70–75% of the property's value, and some will use the projected end value if planning permission is already in place.

• Best for: auction purchases, chain-breaking, quick completions, buying before a refinance.
• Watch out for: the exit. You must have a credible way to repay — sale, refinance or a development loan — and lenders will want evidence of it in writing.

Use bridging as a tool, not a strategy. It buys you time; it doesn't fund a build.

Development Finance: Funding the Whole Project

Development finance is the workhorse of small and medium-sized residential schemes. It covers land acquisition, construction costs and professional fees, with funds released in stages as the build progresses. A quantity surveyor or monitoring surveyor typically verifies each stage before the next tranche is released.

Rates are usually quoted as a margin over base, and most lenders will fund somewhere between 60% and 70% of the gross development value (GDV), or up to around 85–90% of costs if you're contributing land or equity. The loan term runs from six to twenty-four months, with interest often rolled up and repaid from sale proceeds.

The trade-off is control and cost. You'll pay arrangement fees of 1–2%, interest at 0.6–1% per month in many cases, and exit fees on top. You'll also need a detailed cost plan, planning consent, and often a personal guarantee. In exchange, you get a facility sized to the actual job rather than a speculative lump sum.

Private Investment: Equity, Not Debt

Private investors — from a well-off relative to a small syndicate of local professionals — can plug the gap that senior lenders won't touch. This is equity or mezzanine money, sitting behind the bank and taking more risk, so expect them to want more reward.

Typical structures include a fixed return of 10–20% per annum, a profit share, or a combination of both. Some investors want a legal charge over the property; others are content with a share of the SPV. Whatever the arrangement, get it drafted properly by a solicitor who understands property, and be honest about the risks. A disappointed investor is a much bigger problem than a declined application.

• Best for: bridging the gap between the bank's maximum loan and your total costs.
• Watch out for: over-diluting your profit. Work out your return after everyone has been paid, not before.

What Lenders Actually Assess

Underwriters aren't looking for charm. They're looking for evidence. Three things dominate every credit decision.

Experience. Have you completed a project like this before? Lenders want to see a track record — even one or two smaller schemes — with references and completion accounts. If you're new, consider partnering with someone experienced or starting with a refurbishment rather than a ground-up build. A first-timer with a straightforward two-bed renovation is a far easier credit than a first-timer with a six-unit apartment block.

Exit strategy. How does the loan get repaid? An open-market sale, a refinance onto a buy-to-let mortgage, or a pre-arranged off-plan sale all count. What doesn't count is "we'll see how the market is". Have a primary exit and a fallback, and be able to explain both in a sentence.

Projected profit. Lenders stress-test your numbers. They'll want a residual appraisal showing GDV, build costs, professional fees, contingency, finance costs and selling costs. A healthy scheme typically targets a profit on cost of 20% or more, with contingency of at least 10%. If your margin is thinner than that, expect pushback — or a demand for more equity from you.

Practical Steps to Get a Yes

Before you approach anyone, get your paperwork in order. A short, clear pack containing the site details, planning status, cost plan, comparable sales evidence, your CV and a cashflow forecast will do more for your application than any phone call.

• Speak to a specialist broker who deals with development finance daily — high street banks rarely do this well.
• Be realistic about your own contribution; most lenders want to see you have skin in the game.
• Build your contingency, then build it again. Surprises on site are guaranteed, not hypothetical.
• Match the funding to the timeline. Using twelve-month money on a two-year build is a recipe for panic.

Get the finance right and the rest of the project becomes a series of solvable problems. Get it wrong and you'll be selling at a discount to a buyer who can smell your deadlines. Take the time to structure it properly — your future self, standing in a finished kitchen, will thank you.
