UK Property Development, Done Properly.

Most bridging lenders require a 25–30% deposit, so on a £200,000 purchase you need £50,000–£60,000 before build costs. If you want to open up deals beyond what your own capital allows, a joint venture is one of the most common routes — particularly for first-time developers. This might mean partnering with someone who contributes additional capital in exchange for a share of the profit, or partnering with a builder or contractor who reduces the cost of works in exchange for the same. Both are legitimate, both are common, and both can significantly expand what's achievable from day one.

A flip involves buying, refurbishing, and selling a property for profit — your return comes at the point of sale. Buy-to-let means buying a property with the intention of renting it out, generating a regular rental income rather than a lump sum at sale. BRRR (Buy, Refurbish, Refinance, Rent) combines both — you refurbish to add value, refinance to release your capital, then hold as a rental, allowing you to recycle the same money into future deals.

The right answer depends on your long-term intention. Developing in your personal name is simpler to set up — profits are subject to income tax, which works well for a straightforward flip where speed is the priority. An SPV (Special Purpose Vehicle) is a separate limited company that pays corporation tax, and is designed to hold and grow property assets over time — giving you more control over when and how you extract profit, and a more tax-efficient exit when you eventually sell. It's worth getting clear on your direction before you make your first offer.

Bridging finance is a short-term secured loan — typically 6 to 12 months — used to fund a property purchase quickly. Lenders advance up to 70–75% of the purchase price, with the developer providing the remaining 25–30% as a deposit. What this means in practice: if you put in £50,000 and make £30,000 profit on a deal, that's a 60% return on your own money — even if the total project was worth several times that. The leverage is what makes the numbers compelling.

The standard measure is profit on cost — your net profit as a percentage of everything you spent to deliver the project. Most developers target a minimum of 20% profit on cost — it's the margin that gives a well-structured deal room to breathe. The figure only means something if every cost is in the model: purchase price, stamp duty, build, professional fees, and bridging interest.

GDV — Gross Development Value — is the market value of the finished property once all the work is complete. It's the number every other figure on a development is measured against: what you can borrow, what you need to sell for, and whether the deal makes financial sense in the first place. If you buy and build for less than the finished value, the difference is your profit — GDV is how you know what that difference needs to be before you commit.
