Selling your property together with your neighbours can create opportunities that may not exist when properties are sold individually. By combining several adjoining properties into a larger development site, homeowners may be able to attract greater interest from developers and negotiate a higher sale price.
This process is commonly known as a collective property sale, site amalgamation or land assembly.
However, selling multiple properties together is more complicated than an ordinary property sale. Owners need to agree on how the sale will proceed, how the purchase price will be divided and what happens if someone changes their mind. The developer may also require contracts that make the purchase of each property dependent on acquiring the others.
This guide explains how collective property sales to developers work in NSW, the potential benefits, the legal risks and what property owners should consider before committing to a sale.
What Is a Collective Property Sale?
A collective property sale occurs when two or more owners arrange to sell their properties together to one buyer, usually a developer.
The properties are typically adjoining or situated close together, allowing the developer to acquire a larger site suitable for redevelopment.
For example, imagine five neighbouring homeowners who each own a separate house. A developer may be interested in acquiring all five properties to construct an apartment building or townhouse development.
Although each house could be sold individually, the combined land may offer development opportunities that are not available on any single property.
By selling collectively, the owners may be able to negotiate an overall purchase price that reflects the development potential of the combined site.
Importantly, a collective sale does not necessarily mean the owners must combine their land titles before selling. The transaction can involve separate contracts for each property, with arrangements coordinating the sales to the developer.
The appropriate structure depends on the owners' circumstances and what the developer requires.
Why Do Developers Want to Buy Multiple Properties Together?
Property developers often look for opportunities to acquire adjoining properties because a larger site may allow a different or more substantial development.
For example, combining several properties may provide:
A larger overall land area.
Greater street frontage or improved access.
A site configuration better suited to a proposed development.
Opportunities to satisfy minimum lot size or frontage requirements.
Greater flexibility in designing buildings, access arrangements and other infrastructure.
However, combining properties does not automatically mean that a larger development will be permitted.
The development potential of a site depends on the applicable planning controls, which may include zoning, building height limits, floor space ratios, setbacks, heritage restrictions and other requirements.
Property owners can obtain preliminary planning information through the NSW Planning Portal Spatial Viewer. Professional town planning advice may also be necessary to understand the site's realistic redevelopment potential.
A developer will usually assess these matters alongside construction costs, infrastructure requirements, financing, development contributions and the likely value of the completed project.
For that reason, a collective sale is only commercially attractive if the proposed acquisition price is consistent with the developer's feasibility assessment.
Can You Get a Higher Price by Selling With Your Neighbours?
Potentially, yes.
One of the main reasons homeowners consider collective sales is the possibility of achieving a higher price than they could obtain by selling their properties separately.
If a developer needs several adjoining properties to create a viable development site, the combined land may have additional value.
For example, a row of four houses might be unsuitable for a particular development when considered individually, but the combined site could satisfy the relevant size and frontage requirements to allow a developer to build a big enough project to get their required return on investment.
A developer may therefore be willing to offer more than the combined market value of the houses as individual residences.
This is sometimes described as a development premium.
However, there is no guarantee that a collective sale will achieve a premium.
The price a developer is prepared to pay will depend on factors including the permitted development, the site's physical characteristics, the cost of acquiring every property and the commercial viability of the proposed project.
The owners' negotiating position may also be affected by whether every adjoining owner is willing to participate.
Before accepting an offer, homeowners should consider obtaining independent valuation and planning advice. This can help them assess whether the proposed price represents a reasonable commercial outcome.
A higher purchase price also needs to be assessed against any additional expenses, tax consequences, extended settlement periods and risks involved in the transaction.
How Does a Collective Property Sale Work in NSW?
There is no single procedure that applies to every voluntary collective property sale. The process depends on who initiates the transaction, the number of participating owners and the proposed contract structure.
However, most transactions involve several common stages.
1. Establishing Whether Neighbours Are Interested in Selling
A collective sale may begin when a developer approaches several owners or when neighbouring homeowners decide to investigate selling together.
At this stage, the objective is usually to establish whether there is sufficient interest to explore a combined sale.
Owners do not necessarily need to agree on an asking price immediately.
Instead, they may begin by discussing whether they would consider selling, their preferred timing and whether there are circumstances that could affect their participation.
These initial discussions should not be confused with a binding commitment to sell.
2. Assessing the Development Potential and Value of the Combined Site
Before marketing the properties collectively or negotiating seriously with developers, it may be useful to investigate the value and development potential of the combined site.
A property valuer can assist with assessing the current market value of the individual properties and the potential value of the larger site.
A town planner may also be able to advise on the types of development that could be permitted, subject to the relevant planning requirements.
This information can help owners make informed decisions about their expectations and whether a collective sale is worth pursuing.
It is important not to assume that a change in zoning or increased development potential will necessarily translate into a particular sale price.
3. Agreeing on How the Owners Will Work Together
Once several owners express interest, they should consider how the proposed sale will be organised.
For example, who will communicate with developers? Can one owner negotiate on behalf of the others? How will decisions be made? What happens if someone no longer wants to participate?
These questions can become sources of disagreement if they are not addressed early.
A joint sale agreement, sometimes called a collective sale agreement, can be used to document the arrangements between the participating owners.
Depending on the circumstances, it may deal with negotiations, decision-making, costs, the proposed allocation of sale proceeds and the consequences of an owner withdrawing.
Owners should obtain legal advice before signing an agreement that could restrict their ability to deal with their property or impose obligations to other participants.
4. Approaching Developers and Negotiating Offers
The participating owners may decide to approach developers directly, engage a real estate agent or consider offers received from interested purchasers.
A developer's offer should be assessed on more than the headline purchase price.
Important commercial terms may include the deposit, settlement date, due diligence period, access to the properties, planning approval conditions and the developer's rights to terminate the transaction.
For example, a developer offering a higher price but requiring a lengthy option period may not necessarily be offering a better arrangement than a purchaser prepared to enter into a contract with fewer conditions.
The appropriate outcome will depend on the owners' priorities and the risks they are prepared to accept.
5. Preparing and Negotiating the Legal Documents
Once commercial terms have been agreed in principle, the parties need to establish the legal structure for the transaction.
A collective sale may involve separate contracts for each property, coordinated conditional contracts or put and call option agreements.
Each structure can have different implications for the owners and developer.
For example, if a developer only wants to purchase the properties as one complete site, the contracts may need provisions addressing what happens if one of the other acquisitions cannot proceed.
The arrangements should also clarify the parties' obligations, deadlines, deposits and termination rights.
In NSW, contracts for the sale of residential property are subject to prescribed disclosure and other requirements.
A seller is generally bound once contracts are exchanged, and sellers do not have the ordinary residential purchaser's cooling-off right. This makes legal review before exchange particularly important.
6. Satisfying Contract Conditions
After contracts are exchanged, the parties may need to satisfy various conditions before settlement.
These could include completion of due diligence, obtaining planning approvals, securing the remaining properties or fulfilling other contractual requirements.
Where an acquisition involves several properties, conditions and deadlines may need to be coordinated.
If one transaction is delayed or cannot proceed, the consequences for the remaining contracts will depend on how they have been drafted.
7. Coordinating Settlement
The final stage involves completing the property transfers and receiving the purchase price.
In some transactions, the developer may require all properties to settle simultaneously.
Each owner may have different requirements, including discharging a mortgage, obtaining vacant possession or arranging the purchase of another home.
These matters should be considered when negotiating the settlement provisions rather than left until the settlement date approaches.
How Is the Sale Price Divided Between Neighbours?
One of the most important questions in a collective property sale is how the total purchase price will be divided between the participating owners.
There is no general rule requiring owners of separate properties to receive equal amounts.
For example, imagine four neighbouring homeowners agree to sell their properties to a developer for a combined price of $12 million.
An equal division would provide each owner with $3 million.
However, one owner may have a significantly larger property, another may have valuable corner frontage, and another may own a property with improvements worth substantially more than those on the adjoining lots.
The owners may therefore have different views about what constitutes a fair allocation.
Several approaches can be considered:
Allocation method | How it works |
|---|---|
Equal allocation | Each owner receives the same amount, regardless of differences between the properties. |
Land-area allocation | Proceeds are divided according to the relative land area of each property. |
Individual valuation | The allocation is informed by independently assessed property values. |
Negotiated allocation | Owners agree on a division that reflects their circumstances and the contribution of each property to the overall transaction. |
Each method has advantages and limitations.
An allocation based solely on land area, for example, may not reflect the value of improvements or the development significance of an individual property.
Owners should agree on an appropriate allocation method before entering into binding sale arrangements.
The legal documents should also address how sale related costs will be shared and whether different owners will be responsible for their own individual costs.
What Happens if One Neighbour Refuses to Sell?
A collective sale can become difficult where most owners want to proceed but one neighbour does not.
In an ordinary collective sale involving separately owned houses, a developer generally cannot force a landowner to sell simply because adjoining owners have agreed to participate.
Similarly, neighbouring owners cannot ordinarily compel another homeowner to sell their property merely because a combined sale might be financially beneficial.
If an owner refuses, the developer may need to negotiate further, consider a smaller development site or abandon the proposed acquisition.
The position can be different where an owner has already entered into a legally binding agreement. Any contractual rights or obligations would need to be examined.
What About the 75% Rule for Collective Sales?
There is an important distinction between collective sales of separately owned houses and collective sales of strata schemes.
Under Part 10 of the Strata Schemes Development Act 2015 (NSW), eligible strata schemes can undertake a statutory renewal process involving collective sale or redevelopment where the required level of support is achieved.
That process generally involves support from owners of at least 75% of eligible lots, together with other statutory requirements and Land and Environment Court approval.
The 75% rule does not apply generally to a group of neighbouring homeowners selling separately titled houses.
The NSW Registrar General's strata renewal guidance explains the separate statutory process.
What Legal Agreements Are Used in a Collective Sale?
Different agreements may be required at different stages.
The following documents serve different purposes and should not be treated as interchangeable.
Document | Main purpose | Important considerations |
|---|---|---|
Joint sale agreement | Establishes arrangements between participating property owners | Decision-making, price allocation, costs, withdrawal and authority to negotiate |
Heads of agreement | Records proposed commercial terms with a purchaser | Which provisions are binding, exclusivity, confidentiality and future obligations |
Contract for sale | Establishes the terms for selling the property | Price, deposit, conditions, settlement, default and termination |
Put and/or call option agreement | Provides contractual rights concerning a future purchase or sale | Option periods, fees, exercise requirements, restrictions and duty implications |
A joint sale agreement is not necessarily a contract requiring each owner to transfer their property. Its effect depends on the obligations actually created.
Likewise, heads of agreement should not automatically be assumed to be non-binding. Particular provisions may create enforceable obligations even where the parties intend to sign more detailed documents later.
What Are the Risks of Put and/or Call Options?
Developers sometimes use option agreements to secure rights over development sites while investigating feasibility or coordinating other acquisitions.
From a homeowner's perspective, an option may restrict the ability to sell or otherwise deal with the property during the option period.
Depending on the agreement, the developer may have the right, but not the obligation, to proceed with the purchase.
Important considerations include the option fee, the length of the option period, extension rights, the purchase price and what happens if the option expires without being exercised.
Option arrangements can also have significant transfer duty consequences under NSW law. Revenue NSW provides guidance on duty associated with option transactions.
Owners should obtain legal advice before granting an option, particularly where their property forms part of a larger proposed acquisition.
What Are the Main Risks of a Collective Property Sale?
Although collective sales may offer attractive opportunities, there are several risks owners should consider.
Disagreements Between Participating Owners
Owners may disagree about the asking price, the division of proceeds, settlement timing or whether a particular offer should be accepted.
A disagreement can delay negotiations or prevent a transaction from proceeding.
Clear agreements and decision-making arrangements can help manage these issues.
Becoming Committed Before the Entire Site Is Secured
A developer may seek to acquire several properties through separate agreements.
If the documents are not appropriately coordinated, an owner could become bound to sell even where other acquisitions fail.
Alternatively, a developer may negotiate rights allowing it to withdraw if all required properties cannot be secured.
The consequences depend on the contract structure and should be considered before exchange.
Extended Settlement or Option Periods
Developers may seek longer timeframes to obtain approvals, complete investigations or arrange financing.
These timeframes can affect an owner's ability to move, buy another property or make other financial commitments.
Owners should consider whether the purchase price and other terms adequately compensate them for the obligations and uncertainty involved.
Mortgages, Leases and Other Existing Obligations
The properties involved in a collective sale may have very different legal and financial arrangements.
For example, one property may be mortgaged, another may be leased to tenants, and another may be owned by a company or held through a trust.
These circumstances can affect contract requirements, vacant possession, settlement and the tax consequences of the sale.
They should be identified early in the process.
Tax and Transaction Costs
A collective sale can have different tax consequences for different owners.
Capital gains tax, GST and land tax issues should be considered, along with legal fees, valuation expenses and any real estate agent's commission.
A homeowner selling a property that qualifies for the main residence exemption may be treated differently from an investor selling a rental property or an entity selling commercial premises.
The fact that the purchaser is a property developer does not, by itself, determine whether GST or capital gains tax applies.
Owners should obtain advice from their accountant or tax adviser before committing to the transaction, especially where the proposed sale involves unusual arrangements or significant proceeds.
Can All the Homeowners Use the Same Lawyer?
It may be possible for one law firm to act for several property owners participating in a collective sale, but this depends on their circumstances and whether their interests are sufficiently aligned.
For example, a group may agree on a common negotiating position but have different requirements concerning settlement, price allocation or contractual obligations.
A solicitor must consider actual and potential conflicts of interest when acting for multiple clients.
If the owners' interests conflict, separate legal representation may be required.
The issue should be considered before owners engage a lawyer to represent the group, rather than waiting until a disagreement arises.
What Does a Collective Sale Look Like in Practice?
Consider the following hypothetical example.
Four neighbouring homeowners own separate residential properties. A developer approaches them with an offer to purchase all four properties for a proposed apartment development.
Three owners are enthusiastic, but the fourth is uncertain about selling.
The developer explains that the proposed development may not be feasible without acquiring all four properties.
Before signing anything, the owners obtain preliminary advice about the site's development potential and their individual property values.
The owners then consider how they would divide the sale proceeds and what arrangements they would need if they decided to negotiate collectively.
Ultimately, all four owners agree to participate. Their lawyers negotiate coordinated sale contracts, including provisions dealing with the acquisition of the complete site and the timing of settlement.
The owners also address their individual circumstances. One needs an extended settlement, another has a tenant, and a third must discharge a mortgage.
This example illustrates why a collective sale requires more than securing agreement on a headline purchase price.
The owners must also establish arrangements that work for their individual circumstances and allow the overall transaction to proceed.
What Should Property Owners Do Before Agreeing to a Collective Sale?
If you are considering selling with your neighbours, the most useful starting point is to establish whether the proposed arrangement is commercially attractive and what legal commitments it may involve.
Before signing an agreement, consider whether you understand:
The likely value and development potential of the combined site.
Which owners are willing to participate.
How negotiations and decisions will be managed.
How the purchase price and sale related costs will be divided.
Whether any exclusivity or option arrangements are proposed.
What conditions must be satisfied before the sale proceeds.
What happens if a neighbour or developer withdraws.
How settlement timing will affect your personal circumstances.
Whether tax, mortgage or tenancy issues require further advice.
These questions do not all need to be resolved at the first meeting between neighbours. However, they should be addressed at the appropriate stage before legally binding commitments are made.
How Do Developers Approach Collective Property Acquisitions?
From a developer's perspective, collective acquisitions involve balancing the commercial potential of the site against the legal and financial risk of acquiring multiple properties.
A developer may need to negotiate with owners who have different expectations, coordinate due diligence across several titles and ensure the proposed acquisition structure is commercially viable.
Contracts may need to address whether the purchase of one property depends on the acquisition of the others, as well as the consequences of delays, defaults or unsuccessful negotiations.
Developers should also consider the legal issues affecting the individual properties, including easements, leases, covenants and other restrictions.

Frequently Asked Questions About Collective Property Sales
Do all neighbours have to agree to a collective sale?
For a voluntary sale involving separately owned houses, each owner whose property is required will generally need to agree to sell. A developer cannot ordinarily force an unwilling owner to participate. Different statutory rules can apply to eligible strata renewal transactions.
Can homeowners organise a collective sale without a real estate agent?
Yes, homeowners may negotiate directly with developers. However, they should consider whether professional valuation, marketing, negotiation and legal assistance would be beneficial. If an agent is engaged, the agency agreement and commission arrangements should be reviewed carefully.
Does a collective sale always achieve a higher price?
No. A larger site may be more attractive for redevelopment, but the price depends on its actual development potential, market conditions, acquisition costs and the terms a developer is prepared to offer.
How long does a collective property sale take?
There is no standard timeframe. A transaction involving several owners, planning investigations, conditional contracts or options may take considerably longer than an ordinary residential sale. The expected timeframe should be considered when negotiating the agreements.
What happens if the developer pulls out?
The consequences depend on the documents signed and the stage reached. Withdrawal during non-binding negotiations may have different consequences from termination of an option or failure to complete an exchanged contract. Legal advice may be required to determine the parties' rights.
Do owners have to sign a joint sale agreement?
Not necessarily. A joint sale agreement is not universally required for a voluntary collective sale. However, it may be useful to establish arrangements between owners before they undertake coordinated negotiations or make binding commitments.
