Median household income is a key signal for property investors considering Seven Hills. Higher-income areas can sustain higher rents, but they also carry higher entry prices. The yield arithmetic does not always favour premium suburbs. The income distribution also matters: a suburb with a wide spread between low and high earners is undergoing gentrification and may offer stronger capital growth prospects than one with a more homogeneous income profile.
