At the $1M–$1.5M price point, investors chasing cash positive investments face a genuine structural choice. Dual key and rooming house properties both generate multiple rent streams from one title, but they arrive at different purchase prices, yields, and suburb profiles.
Our Take on the Data
Growth doesn't split cleanly by structure. Southport leads at +19.8% but the rest sit within a few points of each other regardless of dual key or rooming house. Yield splits cleanly: rooming house averages 7.8%, dual key averages 4.4%, close to half. Price discipline splits the same way — dual key pays a 37.3% premium over its own suburb's median, rooming house pays 17.1%.
