What Are Property Developers?

Property developers buy land or existing buildings, add value through construction, conversion or refurbishment, then sell the finished scheme or refinance it to hold. The profit is the gap between what the project costs to acquire and build and what it is worth once the work is done.

That is the whole model in one sentence. A developer takes a site worth one figure today, spends money turning it into something worth more, and keeps the difference after costs and finance. An investor, by contrast, buys a property that already produces income and holds it for rent and growth. The developer does the value-adding work.

This guide explains what property developers do, the types of developer, how they make money, and how schemes get funded.

What does a property developer actually do?

A developer manages a project from raw opportunity to finished asset. The work falls into a handful of stages, the same whether the scheme is a single house conversion or a 200-unit block.

• Source the site. Find land or a building with potential, on the open market, at auction, or off-market through agents and sourcers.
• Appraise the deal. Work out the Gross Development Value (GDV), the build cost, the finance cost, and the profit left over. If the numbers do not stack, a good developer walks away.
• Secure planning. Get permission for the intended use: new homes, a conversion, or a change of use under permitted development rights.
• Arrange finance. Most developers use other people’s money. Development finance, mezzanine and equity partners cover the bulk of the cost so the developer’s own cash goes further.
• Build it. Appoint a main contractor, quantity surveyor and architect, then manage the programme, budget and snags.
• Exit. Sell the units, or refinance onto a term mortgage and hold them for rent.

The skill is not laying bricks. It is judging which sites are worth buying, controlling cost and time, and lining up the right finance and exit first.

How do property developers make money?

Developers make money in three main ways, and most experienced operators use more than one. The first is build profit: you buy a site, develop it, and sell the finished units for more than the total cost of land, construction and finance combined. Build three flats that sell at £400,000 each and the GDV is £1.2m; the profit is whatever is left once every cost is paid.

The second is forced appreciation through refurbishment: buy a tired or unmortgageable property, refurbish it, then sell at the higher value or refinance to pull most of your money back out. This is the engine behind buy-refurb-refinance-rent (BRRR), where the developer recycles the same cash across project after project. The third is planning gain: buy land without consent, secure planning permission, and the site is worth more the moment the decision lands, before a brick is laid.

Profit is never guaranteed. Build costs overrun, sales slow, interest accrues, and a thin margin can vanish. Disciplined developers build a contingency into the appraisal and stress-test the exit before they buy.

Types of property developer

Not all developers do the same thing, and lenders price each type differently.

First-time developers are taking on their first ground-up build or major conversion. They can still raise development finance, but lenders look for relevant experience (project management, construction, prior refurbishments), a strong professional team, and usually more equity in the deal at a lower Loan-to-GDV.

Experienced developers have a track record of completed schemes. They access higher borrowing, faster drawdowns, and tools like mezzanine finance. With evidence of past projects, drawdown of stage one can run in 2 to 4 weeks rather than the 4 to 8 weeks a first-timer might wait.

Refurbishment specialists focus on light and heavy refurb rather than ground-up construction, often running a rolling BRRR model. Investor-developers develop to hold, keeping the finished property for rental income rather than selling on.

Property developer vs property investor

The two terms get used interchangeably, but they describe different activities. A property investor buys an asset that already works, a let flat, a tenanted unit, a portfolio, and earns from rent and long-term capital growth. The value-add is light or none. A property developer creates the value by building, converting or improving, then realises it through sale or refinance.

The finance differs too. Investors use longer-term buy-to-let or commercial mortgages underwritten on rental coverage. Developers use short-term, project-based facilities sized against build cost and end value rather than current income. Plenty of people do both.

How do property developers fund schemes?

Development is capital-intensive, and almost no developer funds a scheme entirely from their own cash. The standard structure layers different finance types to keep the developer’s equity input as low as the deal allows.

Development finance is the core facility for ground-up builds, conversions and heavy refurbishments, typically lending up to 80% of Loan-to-Cost and 70% to 75% of Loan-to-GDV, at indicative rates of 6.5% to 9.5% per annum on mainstream residential schemes. Mezzanine finance sits behind the senior lender to push borrowing up to 75% to 80% Loan-to-GDV at a higher rate (indicatively 12% to 20% per annum), freeing equity for the next scheme.

Bridging and land finance secure a site quickly, with or without planning, while the developer progresses to a full facility. Equity and joint-venture finance brings in a partner’s cash for a profit share, useful when a scheme is strong but the developer’s own equity is limited.

All of these figures are indicative. A lender confirms the exact rate, LTV and terms on application, after it has seen the site, the borrower and the exit. Learn how the funding works on our development finance hub.

Frequently asked questions

What is the difference between a property developer and a builder?
A builder constructs to a brief and gets paid for the work. A property developer takes the financial risk: sourcing the site, raising the finance, carrying the cost, and keeping the profit or wearing the loss. Many developers appoint a separate contractor to do the building.

Do property developers need planning permission?
Almost always, yes. Any new build, conversion or change of use needs consent before work starts. Some conversions proceed under permitted development rights, but a developer still confirms the position first. Buying land without consent and securing planning afterwards is a deliberate strategy, not an oversight.

How much money do you need to become a property developer?
There is no fixed figure, because development finance funds most of the cost. The key input is the equity a lender expects you to contribute. First-time developers usually need more equity in and a lower Loan-to-GDV than experienced operators, and the amount depends on the scheme, the lender and your track record.

Can a first-time developer get development finance?
Yes, though it is harder and priced a notch higher. Lenders look for relevant experience, a strong professional team (main contractor, quantity surveyor, architect), more equity in the deal, and a credible exit. A broker can tell you honestly whether your scheme is fundable or whether to start smaller.
