If a property developer has approached you about buying your house, you may be wondering whether the offer is genuine, whether your property could be worth more than you thought, and what you should do next.
You are generally under no obligation to sell your house simply because a developer wants to buy it. Before accepting an offer, it is important to understand why the developer is interested in your property, what it may be worth to them and whether the proposed terms are in your interests.
In some cases, your property may form part of a larger proposed development site involving neighbouring houses. This can create opportunities to negotiate a higher price, but it can also introduce legal and commercial risks that would not ordinarily arise in a residential property sale.
Here are the key things to consider before agreeing to sell your property to a developer in NSW.
Why Would a Property Developer Want to Buy My House?
Property developers often approach homeowners because they have identified land with potential for redevelopment.
Your property might be suitable for a townhouse or apartment development on its own. Alternatively, the developer may be interested in purchasing several adjoining properties to create a larger development site.
For example, your house might be located between two properties that the developer is also attempting to purchase. Acquiring all three could create a site with sufficient land area and frontage for a proposed development.
The developer's interest will usually be influenced by factors such as:
The zoning and planning controls affecting your property.
The size, shape and location of your land.
Whether adjoining properties are available for purchase.
The potential for residential, commercial or mixed-use redevelopment.
Whether the land has access or frontage that is important to the proposed development.
Your property may therefore have commercial value to a developer that differs from its value as an individual home.
However, a developer's interest does not necessarily mean that a larger development will be approved or that the developer is prepared to pay substantially more than market value.
What Should You Do When a Developer Approaches You?
Receiving an unsolicited offer can be exciting, particularly if the amount discussed is higher than you expected.
However, it is worth taking several steps before indicating that you are prepared to sell.
1. Find Out Who Is Making the Offer
Start by establishing whether you are dealing directly with a property developer, a real estate agent, a buyer's agent or another intermediary.
Ask for the name of the proposed purchaser and, if applicable, the company they represent.
If the approach is through a real estate agent, you can check their licensing details using the NSW Government's property agent licence register.
You should also establish whether the person approaching you has authority to negotiate on behalf of the proposed purchaser.
An approach from a developer does not necessarily mean that the developer has approved the acquisition or is ready to proceed with a binding contract.
2. Ask for the Offer in Writing
If a developer expresses genuine interest, ask them to provide an indicative written offer setting out the proposed commercial terms.
At a minimum, you should seek clarification of:
The proposed purchase price.
The identity of the purchaser.
Whether the offer is conditional on planning approval, finance or due diligence.
Whether the developer needs to purchase neighbouring properties.
The proposed deposit and settlement period.
Whether an option agreement or exclusivity arrangement is being requested.
The expected timeframe for making a binding commitment.
A high purchase price may be less attractive if the developer requires considerable time to investigate the property and can withdraw without completing the purchase.
Remember that a written offer is not necessarily a binding sale contract. Its legal effect depends on the wording and the circumstances.
3. Obtain an Independent Assessment of Your Property's Value
Before negotiating, you should understand what your property may be worth.
An ordinary residential market appraisal can be useful, but it may not fully capture the value of a property that forms part of a potential development site.
For example, a developer may require your property to obtain sufficient frontage, site area or access for a particular project.
An independent property valuer with relevant development-site experience may be able to assess the property's value in that context.
Depending on the circumstances, town planning advice may also be useful.
You can obtain preliminary information about zoning and planning controls using the NSW Planning Portal Spatial Viewer.
However, planning information alone does not establish what a developer can ultimately build or how much they should pay.
4. Consider Whether Your Neighbours Have Also Been Approached
If the developer is interested in adjoining properties, it may be worth speaking to your neighbours to find out whether they have received similar offers.
Where several properties are needed for a proposed development, there may be benefits in coordinating negotiations rather than each owner dealing with the developer independently.
For example, the owners may be able to obtain advice about the value of the combined site, negotiate common contractual terms or agree on how a collective sale should proceed.
However, homeowners should avoid making binding commitments to one another without understanding the consequences.
If you are considering a joint sale with neighbouring owners, legal advice can help establish appropriate arrangements before negotiations progress.
5. Speak to a Property Lawyer Before Signing Anything
A developer may ask you to sign a document before a formal contract for sale is prepared.
This could be described as a letter of offer, heads of agreement, exclusivity agreement or option deed.
The name of the document does not necessarily determine whether it creates legally binding obligations.
For example, a document described as preliminary or non-binding could still contain enforceable confidentiality or exclusivity provisions.
Before signing, you should understand whether the document restricts your ability to sell to another purchaser, commits you to particular terms or creates rights in favour of the developer.
A property lawyer experienced in development transactions can help you assess these issues and negotiate appropriate protections.
How Do You Know if a Developer's Offer Is a Good One?
One of the biggest mistakes homeowners can make is focusing exclusively on the purchase price.
A developer may offer substantially more than the property's estimated residential market value while seeking contractual terms that create significant uncertainty.
For example, consider two hypothetical offers:
Offer A: $2.8 million, with an 18-month option period during which the developer can decide whether to proceed.
Offer B: $2.6 million, under an unconditional contract with settlement in 90 days.
Offer A has a higher headline price, but it may leave the owner unable to sell elsewhere for an extended period, with no certainty that the developer will complete the purchase.
Offer B offers a lower price but greater certainty and an earlier settlement.
Neither is automatically the better offer. The appropriate decision depends on your circumstances, the detailed terms and the value of any option fee or other consideration.
When comparing offers, consider the following:
Issue | What to consider |
|---|---|
Purchase price | Is the offer reasonable given the property's market value and potential development value? |
Deposit | How much is payable, when is it paid and what happens if the developer withdraws or defaults? |
Settlement | Will you receive the proceeds within a timeframe that suits your circumstances? |
Conditions | Can the developer withdraw if planning approval, finance or other requirements are not satisfied? |
Option period | How long could the property be tied up before the developer decides whether to purchase? |
Neighbouring acquisitions | Does your sale depend on the developer purchasing other properties? |
Access rights | Does the developer want access for surveys, investigations or other work before settlement? |
An experienced property lawyer can assess the offer as a complete transaction rather than simply considering the proposed price.
Can You Negotiate With a Property Developer?
Yes. A developer's initial offer is not necessarily their final offer.
You may be able to negotiate the price, settlement date, deposit, option terms and other contractual conditions.
For example, if a developer requires an extended option period, you may wish to negotiate an appropriate option fee, limits on extensions or other provisions addressing the uncertainty created by the arrangement.
If you need additional time to relocate, an extended settlement or other agreed arrangement may be important.
You may also want to negotiate restrictions on the developer's ability to assign its rights to another purchaser or request access to the property.
The scope for negotiation will depend on the developer's commercial requirements, the availability of alternative properties and how important your property is to the proposed development.
A developer who needs your property to complete a larger site may have different commercial motivations from an ordinary residential purchaser. Understanding those motivations can be valuable when deciding how to respond.
Be Careful With Option Agreements and Exclusivity Arrangements
Developers sometimes ask property owners to sign option agreements rather than immediately entering into a contract for sale.
A call option generally gives the developer a contractual right to purchase the property during an agreed period, subject to the terms of the option.
Depending on the arrangement, you may be required to sell if the developer validly exercises that right, even though the developer is not necessarily required to proceed.
An option agreement may also restrict your ability to sell or otherwise deal with the property while the option remains in effect.
Important matters include the option fee, exercise price, expiry date, extension rights and what happens if the developer does not proceed.
Put and call option arrangements can create additional obligations and NSW transfer duty consequences. These should be considered before signing.
An exclusivity agreement can also restrict your ability to negotiate with other purchasers, even where no sale contract has yet been exchanged.
These documents should not be treated as harmless preliminary paperwork.
Can a Developer Force You to Sell Your House?
Generally, no.
If you own a separately titled residential property, a private developer cannot ordinarily force you to sell simply because they want your land for a development.
You can decline the offer, negotiate different terms or decide that you do not want to sell.
The same generally applies if your neighbours have agreed to sell their properties but you do not wish to participate.
The position can change if you have already entered into a legally enforceable agreement to sell or granted the developer contractual rights over your property.
Different legal processes also apply to certain strata renewal transactions and compulsory acquisitions by government authorities. These should not be confused with an ordinary private developer approaching a homeowner.
What Happens if You Accept a Developer's Offer?
Agreeing verbally or in principle to a price is not usually the same as entering into a binding contract for the sale of residential property in NSW.
However, any preliminary documents should be reviewed carefully because some may create enforceable obligations.
Once a contract for sale is properly exchanged, the legal position changes significantly. The seller is generally bound to complete the sale in accordance with the contract, subject to any applicable conditions and rights.
This is why the contract should be reviewed and all important issues negotiated before exchange.
A developer's contract may include conditions or special provisions that are not commonly found in a standard residential sale. These could relate to investigations, approvals, adjoining property acquisitions, settlement extensions or other requirements.
You should understand how those provisions affect your rights before becoming legally committed.
What About Capital Gains Tax, GST and Other Costs?
The tax consequences of selling to a developer depend on your circumstances and the nature of the transaction.
For example, a homeowner who qualifies for the full main residence exemption may not have capital gains tax to pay on the sale of their home.
The position may be different if the property has been rented out, used for business purposes or held as an investment.
Selling an existing residential property does not ordinarily attract GST simply because the purchaser intends to redevelop it. However, different rules can apply depending on the property, how it has been used and whether the sale forms part of an enterprise.
Before committing to a substantial transaction, consider the potential tax consequences, mortgage discharge costs, legal expenses and relocation costs.
Frequently Asked Questions
Should I tell my neighbours that a developer wants to buy my house?
It may be worth discussing the approach with neighbouring owners, particularly if the developer needs several properties for its proposed development. However, consider any confidentiality obligations you may have already agreed to, and avoid making commitments on behalf of other owners.
Do I need a real estate agent to sell directly to a developer?
Not necessarily. You can negotiate directly with a developer without appointing a selling agent. However, independent valuation and legal advice may still be important, and an experienced agent may provide useful marketing or negotiation assistance.
Should I accept an offer above my property's market value?
Not automatically. A higher price may be attractive, but you should assess the contractual conditions, deposit, settlement timeframe and whether the developer is legally committed to completing the purchase.
What if I have already signed a letter of offer?
The consequences depend on the wording and circumstances. Some documents are largely expressions of commercial intent, while others contain binding obligations. Have a lawyer review the document promptly before making further commitments.
Should I allow the developer to inspect or survey my property?
You can consider allowing investigations, but the arrangements should be clear. Depending on the work proposed, it may be appropriate to document access times, insurance, responsibility for damage, reinstatement and any obligations concerning information obtained during the investigations.
