For JV & Capital Partners

Partnerships where the paperwork exists before the handshake.

Most property joint ventures fail on ambiguity, not economics. Who decides, who funds an overrun, and who exits first are questions best answered in a document while everyone is still friendly.

01 · A Note From the Founder

I put my name on every pack.
That should tell you something.

Quantum Brick is a young company, and I won't pretend otherwise. But a business built on one rushed deal isn't a business, it's a countdown. I would rather grow slowly on deals that hold up than quickly on deals that don't.

My background is in systems and careful process, and I've brought that into property on purpose: the same twenty-plus checks on every deal, every assumption written down, and a hand-picked network of solicitors, brokers, surveyors and agents, all answering to one accountable person. Me.

You're thinking about a partnership, so here is my promise to JV and capital partners, in one line: roles, returns and risks agreed in writing before any money moves, with independent advice on both sides. The first conversation costs nothing and commits you to less.

02 · The Problem

Why handshake deals fail

Two capable people agree a split over coffee, start spending, and discover six months in that they meant different things by "profit".

Nobody wrote down what happens if the refurb runs over, if one party wants out early, or if the market turns before exit.

By the time it matters, the relationship is already the problem, and there is no document to fall back on.

03 · What You Get

How I structure them

Joint ventures · Lease options · Staged acquisitions · Capital-only positions · Development partnerships · Debt & equity roles

  • i.

    Roles named Who sources, who funds, who project-manages, who signs. Written down before capital moves, so nobody is guessing at their own job.

  • ii.

    Returns defined precisely Not "50/50" but the actual waterfall: what is repaid first, what is preferred, what is split, and on what definition of profit.

  • iii.

    Downside agreed in advance Overrun funding, exit triggers, deadlock resolution and what happens if one party cannot perform, all settled while relations are good.

  • iv.

    Independent advice on all sides Both parties take their own legal advice. I will not structure a partnership where one side is unadvised, because those are the ones that end badly.

04 · The Pack & The Price

Evidence first.
Fees in writing, always.

Joint ventures are priced individually as part of the agreement rather than as a flat sourcing fee, with the basis set out before commitment.

05 · How It Works

Five steps.
You're in control at every one.

  1. 01

    We talk first

    One honest conversation about what you're trying to do. No forms pretending to be relationships.

  2. 02

    I find and filter hard

    Letters to owners, agents who call me first, and street-by-street research. Most of what I see never makes the cut.

  3. 03

    The deal earns its pack

    Full numbers, proof of value, costed work and honest risks, written up only once a deal survives the checking.

  4. 04

    You decide, on evidence

    Question everything, then take the pack to your own solicitor and broker. Proceed only when it truly fits.

  5. 05

    Supported to keys

    I chase the solicitors, brokers and agents so you don't have to. One name answers for everything.

06 · Straight Answers

Questions you should be asking

What do you bring to a JV?+
Depending on the structure: the opportunity itself, the diligence and packaging, the professional network to execute, and the coordination through to completion. What I bring is agreed and documented per deal rather than assumed.
Do I need capital, or can I bring capability?+
Either. Some partners bring funds, others bring building experience, planning knowledge or a track record with lenders. Both are legitimate contributions and both get valued explicitly in the agreement.
How are JV fees handled?+
Differently from standard sourcing. Joint ventures and creative structures are priced individually as part of the overall agreement rather than as a flat sourcing fee, and the basis is set out in writing before commitment.
Is this regulated investment activity?+
No, and it is important to be clear about that. Quantum Brick is not authorised by the FCA and does not give investment advice. Every JV requires independent legal and financial advice on both sides.
