Located in Sydney’s vibrant south-west, Mount Annan has steadily established itself as a hot spot for real estate activity. As we head into 2025, this once-sleepy suburb is attracting increasing attention from both homebuyers and investors. With new infrastructure projects, demographic shifts, and evolving buyer preferences, Mount Annan presents a compelling case for savvy property investors.
In this article, we examine the most important real estate trends in Mount Annan for 2025, and what investors should be aware of before diving into this dynamic market.
1. Continued Population Growth and Urban Expansion
Mount Annan is riding the wave of Sydney’s urban sprawl. The suburb is benefiting from continued population growth in the Macarthur region, driven by affordability and lifestyle appeal. Families are moving away from the inner city to seek quieter neighborhoods without sacrificing access to amenities.
Recent census data and local planning indicators suggest Mount Annan will see a substantial uptick in population through 2025. This growing demand is leading to increased housing developments across the area, particularly for medium-density townhouses and freestanding homes on modest lots.

2. Shift Towards Medium-Density Housing
While Mount Annan has traditionally been dominated by detached homes with large backyards, 2025 is witnessing a shift. Developers are responding to land constraints and changing buyer needs by introducing more medium-density housing such as villas, townhomes, and apartment-style dwellings.
For investors, these properties present an attractive entry point into the suburb with lower upfront costs and strong rental potential. Younger couples and downsizers are especially drawn to the lower maintenance lifestyle these homes provide, without straying too far from nature and amenities.
3. Infrastructure and Transport Projects Fueling Growth
Mount Annan’s appeal is also being bolstered by significant infrastructure investment. Projects such as the continued upgrades to Narellan Road, the Western Sydney Airport development, and expanded bus routes connecting to Campbelltown and Liverpool are improving regional connectivity.
This makes Mount Annan more attractive not only to residents but to businesses and service providers as well. Accessibility improvements often correlate with rising property values, and smart investors are already positioning themselves to capitalize on anticipated demand surges.

4. Strong Rental Yields and Investment Returns
According to local real estate agents and recent data from property analysts, Mount Annan continues to produce solid gross rental yields, particularly in the low to mid-tier property segments. In 2025, gross yields are hovering around 4.2% to 4.7% for houses and slightly higher for units, making the suburb appealing to both short- and long-term investors.
Rental demand remains resilient due to the presence of schools, shopping precincts like Mount Annan Marketplace, sporting complexes, and proximity to major employment hubs. The tenant pool is diverse, comprising families, working professionals, and students from nearby education institutions.
5. Environmental Appeal and Green Space Access
Another feature setting Mount Annan apart is its natural beauty and abundance of green space. The suburb is home to the awe-inspiring Australian Botanic Garden, stretching over 416 hectares and offering hiking trails, picnic areas, and events year-round. This natural appeal is a major draw for both buyers and renters seeking respite from urban density.
As sustainability and environmental considerations rise in importance among younger demographics, properties near green spaces and with eco-friendly features are seeing increased demand. Savvy investors may consider properties with solar panels, energy-efficient appliances, or proximity to walking and bike trails to future-proof their investments.
