Detention is a smaller community of 35 — about 1% of the Tasmania suburb median (3,902) — so investors should factor in the narrower buyer pool and longer average time-on-market. Detention's median household income of $6,812/year is 91% below the Tasmania suburb median ($73,944) — this is an affordability play where returns lean on yield and patient capital growth rather than demographic premium. Detention is 272 km from Hobart, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand.

The main risks are a thin buyer pool (35 residents), interest-rate sensitivity on the $1,986 median mortgage, below-median household incomes ($6,812 vs $73,944 state median), the broader Tasmania market cycle. Each of these is covered in the Risk Factors section above with suburb-specific numbers rather than generic warnings.
