In recent years, we have observed a remarkable trend across the Sydney property market, from the Inner West to the North Shore and the Hills: home owners are banding together to sell their properties as “mega lots” to developers, achieving sale prices far above individual market value. For property buyers, this phenomenon has significant implications, both in terms of market dynamics and the strategies required to secure a desirable property. As buyers’ agents, we are uniquely positioned to help buyers to navigate this evolving landscape.
What Is a “Mega Lot” Sale?
A “mega lot” sale occurs when a group of neighbouring home owners collectively sell their properties as a single, large parcel to a developer. Rather than selling individually to residential buyers, these owners combine their landholdings, creating an amalgamated site that is highly attractive for large-scale redevelopment, such as apartment complexes or mixed-use projects. The result is often a sale price per property that is two to three times higher than the standard market value.
Recent Examples in Sydney
- Mosman, Lower North Shore: In May 2025, six homeowners on Rangers Avenue sold their properties together for approximately $60 million. The median house price for a four-bedroom home in Mosman is around $5 million, yet these owners achieved up to twice that figure due to the site’s redevelopment potential following changes in zoning regulations.
- Baulkham Hills: 26 residents formed a collective to sell their properties as a mega lot for $60 million, capitalising on new medium-density zoning that made the site highly desirable to developers. Each owner is expected to make a windfall of approximately $1.15m.
- Cheltenham and Epping: Groups of eight neighbours each aggregated their properties, selling for $9 million and $30 million respectively—up to three times their individual market values.
Why Are Mega Lot Sales Achieving Sky-High Prices?
The driving force behind these extraordinary sales is the growing demand for land suitable for high-density development. Several factors contribute to this:
- Rezoning and Urban Consolidation: The State Government is encouraging higher-density living to address Sydney’s population growth. Major planning and rezoning reforms such as the Low and Mid-Rise Housing Policy are being implemented. Rezoning allows for the construction of townhouses, terraces, and mid-rise apartments in areas previously limited to detached houses.
- Developer Demand: Developers are willing to pay a premium for large, contiguous sites that can support significant projects. The economies of scale and planning efficiencies make mega lots highly attractive investments.
- Infrastructure Improvements: Proximity to new or planned transport infrastructure, such as train stations, further increases the value of these sites, as developers anticipate strong demand from future residents.
Implications for Property Buyers
Increased Competition and Changing Neighbourhoods
As more home owners opt for mega lot sales, we will see entire streets or blocks transformed by new developments. This can lead to:
- Increased competition for established homes in desirable locations, as the supply of desirable family homes contracts.
- Rapid changes in neighbourhood character, density, and amenities.
- The emergence of off-market opportunities, as many mega lot deals are negotiated privately between home owners and developers, bypassing traditional listings.
The Importance of Expert Guidance
For property buyers—whether seeking a family home or an investment property—navigating this environment requires strategic insight and local knowledge. This is where buyers’ agents play a crucial role.
The Role of Buyers’ Agents in a Mega Lot Market
Buyers’ agents act exclusively for the buyer, providing a suite of services designed to secure the right property at the best possible terms. In the context of mega lot sales and rapidly changing markets, our expertise is more valuable than ever.
Key Services Provided by Buyers’ Agents
- Market Analysis and Due Diligence: We analyse zoning changes, development trends, and recent mega lot sales to identify areas at risk of rapid transformation or those offering unique opportunities.
- Access to Off-Market Properties: Through our network, we can identify properties before they are publicly listed, including those that may be part of future mega lot sales.
- Negotiation and Advocacy: We negotiate on your behalf, ensuring you do not overpay in a competitive or speculative market, and that your interests are protected throughout the transaction.
- Property Selection and Appraisal: We provide objective assessments of properties, factoring in future development potential, neighbourhood changes, both positive and negative, and long-term value.
- Managing the Process: From initial search to settlement, we coordinate inspections, liaise with solicitors and conveyancers, and manage all aspects of the purchase to ensure a seamless experience.
Strategic Considerations for Property Buyers
1. Understand the Local Market Dynamics
Before committing to a purchase, it is essential to understand whether the area is a target for future mega lot sales or redevelopment. This can affect both the long-term value and the living environment of your prospective property.
2. Assess the Impact of Zoning and Infrastructure
Changes in zoning can dramatically alter the development potential of a site. We monitor council plans and infrastructure projects to advise our clients on areas likely to experience significant change.
3. Consider the Pros and Cons
- Opportunities: Buyers may benefit from purchasing in areas before rezoning, capturing future capital growth as the area transforms.
- Risks: Conversely, buyers may find themselves living next to major construction sites or in neighbourhoods that change character rapidly with growing populations putting pressure on existing amenties.
4. Leverage Professional Representation
With the market becoming more complex, professional buyers’ agents provide a critical advantage. We ensure that our clients have access to the best properties, are fully informed about market conditions including the strengths and weaknesses of each individual property, and secure their purchases on favourable terms.
