The median selling price for detached houses in Mount Annan rose to about $1,100,000 between 2024 and June 2025, which is about a 5.7 percent increase from the previous year. Most of the growth is fuelled by the ongoing demand for families wanting to upgrade to a more spacious and relaxed lifestyle within Greater Sydney.
Entry-level three-bedroom homes experienced the same trend, with the median increasing to around $903,500. Four-bedroom homes with dual living areas and outdoor entertainment areas are particularly in demand, tending to attract multiple offers within a short time of being put on the market.
This increase in house value is also indicative of the suburb having a restricted new housing stock and growing popularity among buyers who cannot afford suburbs closer to Sydney, such as Narellan or Oran Park.9
Who Is Purchasing in Mount Annan?
The demand is primarily led by families, a number of whom are coming from more compact suburbs looking for more room and a sense of belonging.
What Buyers Are Seeking
- School district, particularly for Mount Annan Public and Mount Annan HighProperties with room for a home office or backyard studio
- Proximity to walking trails, sports grounds, and quiet streets
- Although the first-home buyer remains, they are increasingly being pushed out by established buyers who bring more equity to the table.
- Investors are also coming back, especially those interested in long-term growth and consistent rental returns.
Demand-Influencing Infrastructure Projects
Several local and regional infrastructure upgrades are facilitating further access to Mount Annan.
Major Developments
- Widening Narellan Road to reduce congestion
- Bus facilities to Macarthur Square and Campbelltown Station have been improved.
- Cycling and pedestrian pathways have been established throughout pockets of housing.
- The Growth Area is still expanding, and Mount Annan will benefit from planning that aims to enhance accessibility, walkability, and family-friendliness.
Rental market: Low Vacancy, Healthy Yields
The rental sector is also on the boil. Three- and four-bedroom house rents are increasing as tenants seek space to fit in with remote working and expanding families.
What’s Fueling Rental Growth
- Limited rental inventory
- Strong regional demand from professionals and families
- Few new rental developments in the short term
- Properties located close to schools, shops, and bus routes tend to lease quickly.
Investors are noting that the suburb’s gross yields, hovering around 3.5 to 4 percent, are relatively stable compared to more volatile inner-city markets.
Community Amenities Boosting Liveability
The past 12 months have seen significant additions to Mount Annan that have transformed this suburb into a community capable of meeting diversifying needs.
- Development of Mount Annan Central with additional specialty stores and cafes
- Renovated Leisure Centre with enhanced aquatic facilities and gymnasium
- Additional community events and weekend markets in the surrounding reserves
- Surrounding states like Harrington Park, Spring Farm, and Currans Hill are also experiencing indirect advantage as residents broaden the search for properties to include nearby areas.
Land Supply and Trends in Construction
Mount Annan is largely developed, hence minimal new land releases. Subdivision of larger blocks and replacement of ageing homes with dual-occupancy houses or townhouses is the focus for developers.
Recent Trends
- Smaller lot subdivisions are increasingly popular
- Building costs continue to be high due to material shortages
- Turn-key packages are sought after, but with hold-ups
- Increased council-imposed density restrictions and the lesser number of free blocks have increased the values of established houses, as they sell faster than the outer suburbs.
Forecast 2025: Modest Growth Expected
A conservatively optimistic outlook for the remainder of 2025.
Key Follow-up Factors
- RBA interest rate changes
- Continued migration and housing demand
- Changes in building regulations and zoning reviews
If the interest rates decrease, more buyers will be inclined to come back into the market, particularly those who had been waiting. The demand may, in turn, put additional pressure on prices if housing supply fails to increase proportionally.
Projection shows a 3 to 6 percent increase in home values for Mount Annan, as long as the overall economic conditions are stable.
