A property joint venture combines what one person has with what another person lacks. One partner has capital. The other has time, experience, or sourcing ability. Together they buy, develop, or manage a property and split the profits.
JVs are common in UK property, particularly for development projects, BRRRR strategies, and HMO conversions where the total investment exceeds one person's capacity. When they work, both parties earn more than they could alone. When they fail, the fallout is expensive.
Common structures
Capital plus management. Investor A provides the deposit and funds the purchase. Investor B sources the deal, manages the refurbishment, and handles the day-to-day. Profits split 50/50 or 60/40 in favour of the capital partner (reflecting the financial risk).
Capital plus capital. Two investors pool deposits to buy a more expensive property than either could afford alone. Management is shared or delegated to one party. Profits split in proportion to capital contributed.
Experience plus capital. An experienced developer partners with a passive investor. The developer runs the project from acquisition to sale. The investor provides the cash. Typical split: 50/50 after the investor receives their capital back plus a preferred return (8-12% per annum).
The JV agreement
Every joint venture needs a written legal agreement. Verbal agreements and handshake deals are the number-one cause of JV disputes.
The agreement should cover: each party's capital contribution (how much, when, and into which account), each party's responsibilities (who does what), the profit-split formula (including how "profit" is calculated, which matters more than you think), decision-making authority (who has final say on offers, contractor selection, sale price), dispute resolution (mediation before litigation), what happens if one party wants to exit, what happens if one party fails to perform, and the holding structure (personal names, partnership, limited company, or SPV).
A solicitor-drafted JV agreement costs £1,500 to £3,000. Skipping it to save money is the worst false economy in property.
Where JVs go wrong
Undefined profit calculation. "We split the profit 50/50" means nothing if you have not agreed what counts as a cost. Does the managing partner's time count as a project cost? Are interest payments deducted before the split? What about SDLT, CGT, or accountancy fees?
No exit terms. One partner wants to sell after 12 months. The other wants to hold for five years. Without agreed exit triggers and mechanisms (forced sale, buyout price formula, put/call options), the partnership deadlocks.
Mismatched expectations. The capital partner expects monthly updates and a say in every decision. The managing partner expects autonomy. If roles and communication expectations are not set out in the agreement, resentment builds.
One party underperforms. The managing partner does not deliver the refurbishment on time or on budget. The capital partner does not transfer funds on schedule. The agreement should specify consequences for non-performance, including the right for the other party to step in or exit.
Tax implications
How you structure the JV affects tax. A partnership (formal or informal) means each partner is taxed on their share of profits at their personal tax rate. An SPV limited company means profits are subject to corporation tax and dividends are taxed when extracted.
For one-off development projects (buy, refurbish, sell), HMRC may treat the profit as trading income rather than a capital gain, which affects the tax rate and available reliefs. Take tax advice before choosing the structure.
