Mount Johns is a smaller community of 541 — about 18% of the Northern Territory suburb median (3,057) — so investors should factor in the narrower buyer pool and longer average time-on-market. At $117,988/year, household income in Mount Johns is within 4% of the Northern Territory median ($113,308), placing the suburb firmly in the state's mainstream demographic band. Median rent of $345/week (~$1,495/month) covers only 69% of the median mortgage of $2,167/month — the remaining $672/month must be funded from other income, so this suburb tilts toward capital growth rather than yield. Mount Johns is 1293 km from Darwin, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand. Only 17% of dwellings are separate houses (vs 68% state median), so this is a unit-heavy market where body-corporate decisions and strata supply meaningfully shape investor returns.

Mount Johns has a usual resident population of approximately 541, compared with a Northern Territory suburb median of 3,057 — placing it in the lower half of the state's suburbs by size.

The most recent census recorded a median weekly rent of $345 in Mount Johns, equating to approximately $17,940/year in gross rental income (state median $360/week).

The median monthly mortgage repayment in Mount Johns is $2,167, or approximately $26,004/year (vs $1,950/month state median). Stress-test your own borrowing at rates 1–2 percentage points above today's to make sure you can still service the loan through an RBA tightening cycle.
A median weekly rent of $345 works out to $1,495/month, covering 69% of the median mortgage repayment of $2,167/month. That leaves a $672/month shortfall (around $8,064/year before tax benefits), so a typical owner-occupier-priced property here is negatively geared. Actual cash flow depends on your deposit, loan terms, ownership costs and marginal tax rate — run the full numbers in our rental yield calculator.
The main risks are a thin buyer pool (541 residents), interest-rate sensitivity on the $2,167 median mortgage, a unit-heavy dwelling mix (17% houses) where body-corporate costs and apartment supply affect resale, the broader Northern Territory market cycle. Each of these is covered in the Risk Factors section above with suburb-specific numbers rather than generic warnings.
