Dual occupancy—also known as dual key—homes are modern properties designed to accommodate two separate living spaces on a single block of land. While the dwelling looks like a single home from the outside, the internal layout is divided into two private residences, each with its own entrance, kitchen, bathroom, and living areas. In Perth, this model has become increasingly popular with investors and owner-occupiers seeking flexibility. You can live in one side and rent out the other, rent both for dual income, or use the secondary residence for family members, downsizing parents, or adult children who need independence.
Dual occupancy properties offer a unique financial advantage: two rental incomes from one land purchase. In a market like Perth—where population growth, housing demand, and rental shortages remain strong—this type of investment often achieves higher rental yields than traditional single dwellings. Because both residences are under a single title, you avoid extra land tax and reduce holding costs, while enjoying a higher rental return. Over time, dual income properties also tend to grow strongly in value, as the demand for affordable, flexible living solutions continues to rise across Western Australia.
For many investors, dual occupancy homes outperform standard houses for both cashflow and long-term strategy. With two income streams, vacancy risk is lower—if one side becomes vacant, the other continues generating income. Construction costs are often only slightly higher than a standard home, yet the rental returns are significantly greater. Dual occupancy properties also appeal to a wide range of tenants including couples, small families, downsizers, and students, making them easier to rent in almost any market. In simple terms: one block, one set of rates, double the revenue potential.
