Joint Venture Development Finance: How Does a Property JV Work?

Written by Justin, Principal · 13 October 2026 · Updated · 5 min read

Our guides are researched and drafted with digital tools, then written and approved by Justin, Principal, from his own experience.

Some senior lenders will go up to 70% of gross development value (GDV) for the right developer with the right track record. A JV partner can help with the gap.

Picture the appraisal. The senior lender will lend up to a set share of the scheme's value. Your own cash covers a slice. A gap sits in the middle, and it will not close however long you stare at the spreadsheet.

A joint venture (JV) is one way to close it. This guide explains how a property JV works, and when joint venture development finance may suit you better than mezzanine.

The 30-second version

  • What it is: a partner joins you on one scheme and puts money into it. The agreement between you sets out how the result is shared. It is not a loan.
  • What it costs: a JV is not a loan, so there is no loan rate. Mezzanine, by comparison, is priced above senior debt, case by case.
  • The catch: the agreement between you needs careful drafting.

What is joint venture development finance?

A property JV brings two or more parties together to fund and deliver one scheme. You usually bring the site, the planning, the know-how or some cash. The partner brings money. A senior lender then provides the main loan.

The partner is not a lender. That is the difference from mezzanine, which is debt priced above senior debt, case by case.

A JV is often held in a special purpose vehicle (SPV) set up for the one scheme, such as a limited company or an LLP. Take legal and tax advice early.

How the agreement works

A members' or shareholders' agreement should set out who makes day-to-day decisions, which decisions need both of you and what happens if you disagree. It is the heart of a JV.

Use a solicitor who knows development JVs.

The senior lender takes a first charge over the scheme. A senior lender may want to see the JV terms, so show them early.

JV, mezzanine or something else?

Your situation What it may point to What is commonly done next
You are open to a second party in the scheme A JV may be worth a look Run the appraisal both ways first
The margin is modest and you want to stay in sole control Mezzanine may suit you: priced above senior, case by case Ask for the full cost, including fees, before you compare
You have a gap and a strong track record Stretch finance can take borrowing further (see below) Ask about the stretch first
A contractor wants to join the scheme A contractor JV See the contractor section below
You do not want a third party in the scheme Mezzanine or a stretched senior loan Compare the full cost of each before you decide

What I am seeing now: contractors as JV partners

In my experience, the JV partner is not always an outside funder. I have three schemes running with a contractor as the partner. One is around £20m and one is well over £50m. Two are Gateway 2 schemes.

In the schemes I am seeing, the contractor helps fund, if not fully funds, the Gateway 2 costs. In those schemes it also defers its full 3% retention, and some or all of its profit, until the lender is repaid. That helps cash flow.

Gateway 2 (building control approval from the Building Safety Regulator before work starts) applies in England to higher-risk buildings: at least 18m tall or at least 7 storeys, with at least 2 residential units (care homes and hospitals too; hotels are excluded). Below that, it does not apply.

How far borrowing can go

Senior debt goes up to 70% of GDV for the right developer, and up to 75% with extra security or pre-sales in place. Stretch senior and mezzanine can take total borrowing up to 85% of GDV.

What a partner (and a lender) may look at

A partner and a lender will each look closely at the scheme before they commit.

  • Track record. Lenders look at your track record, and at anything that adds to the scheme's value.
  • The exit. A lender will want a specific exit before it issues an offer: a clear route to sale or refinance.

Before you approach a JV partner: four questions

  1. What will each side put in: cash, land, planning or time?
  2. What happens if you disagree, or one side wants out?
  3. Who can make decisions alone, and which need both of you?
  4. Have you shown the senior lender the structure?

For a structure where an institution funds the build and buys the finished scheme, see forward funding. It is a different route from a JV.

Frequently asked questions

Do I need my own money in a JV?

Not always in cash. Your share can be land, planning or time instead.

Can a first-time developer do a JV?

It can be. Lenders look at track record, so the team around you matters. Tell us about the scheme. We arrange loans; we do not lend.

What should I have ready before I talk to a partner?

Your appraisal, planning position and exit plan.
