Co-investing in property development

26 October 2026

Co-investment lets private investors put capital into a development scheme alongside a developer. Instead of buying a finished property, you fund part of the cost of creating new homes and share in the outcome. It can be a way into development without running a site yourself, but it carries very different risks from buying a buy-to-let.

This guide explains how co-investment usually works and what to check before committing.

How a development is funded

Most residential schemes are funded with a mix of debt and equity, often called the capital stack:

Co-investors usually sit in the equity. That means you are repaid after the lenders, and you carry the first loss if costs rise or values fall. In return, equity takes a share of the profit rather than a fixed interest rate. Our article on how property development is funded shows illustrative examples of how these layers fit together.

Common co-investment structures

Each structure has different tax, legal and control implications, so take independent legal and tax advice.

Questions to ask a developer

Pay particular attention to alignment. A developer who invests meaningful capital in the same scheme, on the same terms, has every reason to protect it.

Reading an appraisal

An appraisal shows the expected GDV, costs and profit. Treat it as a set of assumptions, not a promise. Test the sales values against recent local sales, check the build cost against the specification, and look at what happens to profit if values drop or costs rise by 5 to 10 per cent. A scheme that only works if everything goes to plan is a risky scheme.

Is co-investment right for you?

Co-investment in development tends to suit investors who understand property, can leave capital untouched for several years, and can afford to lose some or all of it. It is not a substitute for cash savings or a pension. Speak to a regulated financial adviser before deciding.

Capital is at risk. Property development investments are illiquid and returns are not guaranteed. This article is general information, not financial advice.
