For investors considering Thornleigh (2120), gross yield is the starting point, but it is the net yield after outgoings (council rates, strata levies, property management, maintenance) that determines actual cash-flow position. The figures shown are gross. As a rule of thumb, subtract 1.5 to 2.5 percentage points to arrive at a net yield estimate, depending on property type and strata status.

A low vacancy rate in Thornleigh indicates strong tenant demand relative to supply, typically a positive signal for landlords and a sign that the suburb has sustained rental appeal. Vacancy rates below 2% in Sydney are generally considered a landlord's market; above 3% signals softer conditions. Compare the Thornleigh rate to the wider Hornsby LGA to understand whether it is suburb-specific or part of a broader area trend.
