Property Development Investment From Both Sides of the Table

We work for developers. Our job is arranging the debt and equity that gets a property scheme built, which means we spend a great deal of time explaining to developers what the investors on the other side of the table are actually thinking about.

This is that explanation, written down. It describes how property development investment works, where the capital sits, what it is paid and when. It is not advice, it is not a recommendation, and nothing here is an invitation to invest in anything. Anyone considering putting money into a property development scheme should take independent legal, tax and financial advice on the specific proposal in front of them, because capital placed in a development can be lost in full.

Development equity is the last money paid and the first money lost. Every discussion about what it earns has to start there.

What does it mean to invest in property development?

To invest in property development is to place capital into the construction of a property or a group of properties, in exchange for a share of the profit realised when they are sold or refinanced.

That is a different activity from owning property. A rental property produces income from an existing property. Development projects produce a capital profit from a property that does not exist yet, and every pound of that profit depends on the building being finished and sold at the values in the appraisal. The location of the site matters enormously to whether it will sell at all.

Three characteristics define this kind of property investment. It is illiquid, because the capital is committed until the property completes and the units sell. It is subordinated, because senior debt at 65 to 70 percent of gross development value across our lender panel ranks ahead of it. And it is binary in a way rental property is not, because a development that stalls half built produces no income at all while the interest on the senior debt continues.

The capital normally sits in shares in a special purpose vehicle rather than in a loan, which is what makes it equity rather than debt, and which is why it is paid last.

How is property investment different from development investment?

By what produces the return.

Traditional property investment buys an existing property and holds it. The return comes from rental income and from any growth in the value of that property over time. A commercial mortgage on such a property is priced from 5.5 percent a year with the rent required to cover 125 to 150 percent of the payment, and the whole structure is built around an income stream that already exists.

Property development investment funds construction. There is no rental income during the build, no tenant, and no valuation to refinance against until the property is finished. The return is a share of the margin between what the scheme cost and what the property sells for.

Four practical differences follow, and investment property buyers moving into development consistently underestimate all four.

Timing. A rental property portfolio pays monthly. Development projects pay once, at the end, possibly late.

Sensitivity. A 10 percent fall in property values reduces a rental yield modestly. On a development project with a 20 percent margin, it can remove most of the profit.

Exit dependence. A rental property can simply be held through a weak property market. A development has to sell, or be refinanced, and the finance has an end date.

Information. With an investment property you can inspect the tenant, the lease and the rent. With a development you are assessing a forecast.

None of that makes development investment worse. It makes it different, and the investors who lose money are usually those who priced it like ordinary property investment.

What are the ways to invest in a development project?

Four routes exist and they carry very different risk positions.

Direct equity in a single property scheme. Shares in the special purpose vehicle, a seat in the waterfall, and a profit share negotiated with the developer that runs 40 to 60 percent to the funding side across our lender panel. Highest exposure, and the only route with real influence over the property.

Secured lending to a development. Providing debt rather than equity, with a legal charge over the property. Lower return, ranks ahead of the equity, and is a regulated activity in some circumstances.

Platform based investment. Crowdfunding and peer to peer platforms aggregate many investors into one position. Investors on those platforms are putting capital at risk and should read the platform’s own risk disclosures.

Listed or fund exposure. Shares in housebuilders, real estate investment trusts or property funds. Liquid, diversified across many property developments and many locations, and entirely different in character from backing a single project.

We arrange the first two on behalf of developers seeking funding. We do not advise anybody on which of these is suitable for them, and that question genuinely requires a regulated adviser rather than a broker.

How to get investment for property development as a developer?

By making the case somebody else’s risk committee can approve.

This is the side of the table we work on, and the requirements are consistent. A full property appraisal with build costs referenced to current tender prices. Sale values tested against Land Registry sold prices for the immediate location rather than against asking prices, because an appraisal pitched 8 to 10 percent above recorded property transactions is the commonest reason a proposal stalls. A planning consent, or a very short route to one. A named contractor and a costed programme. Senior debt terms already agreed or clearly obtainable. And a track record presented honestly, including the difficult project.

Two things move a proposal faster than anything else. A developer contribution, even a modest one, because investors read money in the deal as commitment. And competitive tension, because a developer speaking to three funders is having a different conversation from one speaking to a single funder. That is as true of land deals as of built property.

The order of operations matters too. Arrange the senior development finance first, from 6.5 percent a year at 65 to 70 percent of gross development value, over a Bank of England base rate of 3.75 percent held since December 2025. Then price the mezzanine option. Only then go looking for equity investment, because equity is the most expensive capital in the building and a developer who has not tested the cheaper layers of finance is giving away profit unnecessarily.

Does the 2 percent rule tell you anything about property development returns?

Nothing at all, and it is worth saying plainly because the question is asked constantly.

The 2 percent rule is an American screening heuristic for rental property: monthly rent should equal 2 percent of the purchase price. In the United Kingdom, where residential yields are structurally lower and financing and tax work differently, almost no property investment meets it, and applying it to buy to let stock here produces an empty list of properties.

Applied to a development it makes even less sense, because a property development scheme produces no rent. The measures development actually uses are profit on cost, generally expected in the region of 20 percent for a scheme to be fundable, profit on gross development value, and the sensitivity of both to changes in build cost and sale price. Any assessment of a development project that does not include those three numbers is incomplete regardless of what rule of thumb is applied on top.

Is it worth investing in property development?

That is not a question anybody should answer for you, and certainly not a broker writing an article.

What can be said descriptively is what the trade consists of. The investment ranks behind the senior lender and behind any mezzanine debt. It receives no income during the build. It is illiquid until the property sells. In exchange it participates in a profit share rather than an interest rate, which means the upside is not capped and the downside includes losing the whole amount.

Whether that suits any particular person depends on their circumstances, their other assets, their tax position, their tolerance for illiquidity and their ability to absorb a total loss. Those are matters for an independent financial adviser, and the honest answer to the question as asked is that we are not able to give it.

What we can say is what makes a proposal weaker rather than stronger. A developer with no completed projects. An appraisal with a contingency below what a quantity surveyor would insist on. No agreed senior finance. Sale values above recorded property comparables. A structure where the developer has no money at risk. And a projected return quoted as though it were certain, which is the clearest signal in the whole property market.

How does a residential property investment portfolio compare?

Differently enough that they are not really alternatives.

A residential rental portfolio produces income from tenants, can be held indefinitely, is financed on term debt, and can be sold one property at a time. Its risks are voids, arrears, regulation, maintenance and interest rate movement. Values move with the wider property market and the investor’s involvement is largely administrative.

Development projects produce no income, have a defined end, are financed on facilities with expiry dates, and cannot be sold in pieces until the property is built. Its risks are construction cost, programme, planning and the sales market at one particular moment. The investor’s involvement is a governance role rather than a management one.

The two do behave differently in a downturn, which is why some investors hold both, but that is an observation about how the assets work rather than a recommendation to do it. Anyone building a property portfolio across both should take proper advice on the mix.

There is a practical crossover worth noting for developers. A scheme intended for sale can sometimes be retained instead, refinancing the development facility onto commercial mortgages at up to 75 percent loan to value with rent covering 125 to 150 percent of the payment. That converts a development into a rental asset, and it is a genuine option when the sales market is thin.

What risks sit inside a development investment?

Six, and they compound rather than sit side by side.

Construction cost. Materials, labour and specification. A fixed price contract with a credible contractor transfers much of this, and its absence is the largest single warning sign in any proposal.

Programme. Every month of overrun costs interest on the senior debt and pushes the sale into a market nobody has seen yet.

Planning. Conditions to discharge, section 106 obligations, and the possibility that what was consented is not what gets built.

Sales. The property values in the appraisal are forecasts. Land Registry data tells you what has sold, not what will sell.

Counterparty. The developer’s capability and solvency. This is the risk that diligence actually reduces.

Structure. Where the investment sits, what security exists over the property, and what happens on a cost overrun. Two identical schemes with different documents produce entirely different outcomes for the same money.

Capital placed in a development scheme is at risk and can be lost in full. That is not a disclaimer bolted onto the end of a list, it is the defining characteristic of the position.

Where do commercial developments differ for an investor?

In the exit, mostly.

A residential property scheme sells to individual buyers over a sales period, so the risk is spread across many small transactions in a deep market. Commercial developments frequently depend on a single occupier or a single institutional investment buyer, which concentrates the risk enormously. A pre let or a forward sale removes most of that concentration and is worth far more in a commercial proposal than in a residential one.

Commercial property also values on income rather than on comparable sales. The finished property is worth its rent divided by a yield, so a small movement in yields changes the gross development value materially, and investors assessing a commercial scheme are taking a view on the property investment market two years out as well as on the build.

Mixed use developments carry both sets of risk, and the commercial element is usually the part that is hardest to place. Developers should assume the ground floor units let last and price the funding accordingly.

When should a developer sell rather than seek investment?

When the arithmetic says the scheme is worth more to somebody else.

A consented site with no funding behind it has a value that a developer can simply realise. Sell the land, or sell the project as a going concern, and it produces cash today with no construction risk and no profit share. Against that, building it out with an equity partner produces 40 to 60 percent of a larger number in two years’ time, with the risk of producing nothing.

Three situations point clearly at a decision to sell. A margin too thin to survive a 10 percent cost movement. A developer without the capacity to deliver the property’s size or type. And land whose value comes from the consent rather than from the build, which is common on strategic sites and on plots where a housebuilder will pay more than the scheme is worth to a small developer.

Everywhere else, funding it properly is the better answer. We arrange equity and joint venture funding, development finance and commercial mortgages for developers across a panel of over 100 lenders.
