Lambells Lagoon is a smaller community of 239 — about 8% of the Northern Territory suburb median (3,057) — so investors should factor in the narrower buyer pool and longer average time-on-market. Household income of $105,248/year is 7% below the Northern Territory median of $113,308, typically translating into lower entry prices and a tenant base more sensitive to rent increases. Weekly rent of $135 covers just 31% of the median $1,875/month mortgage repayment, leaving a $1,290/month gap — investors should only pursue this suburb with a clear capital-growth thesis and sufficient external income to fund the shortfall. At 45 km from Darwin, Lambells Lagoon is an outer-metro location where buyers are typically trading commute time for floor space and a lower entry price.

Limited buy-and-hold upside: a small population of 239 means liquidity is thin and capital growth tends to lag the wider Northern Territory market over full cycles.
Weak cash flow: $135/week rent covers only 31% of the $1,875/month median mortgage — a $1,290/month gap that must be funded from other income. This suburb is a capital-growth play, not a yield play.
With 75% houses in a 239-person market, renovation margins depend on individual street and aspect rather than any suburb-wide story — do comparable-sales analysis before committing capital.

The median monthly mortgage repayment in Lambells Lagoon is $1,875, or approximately $22,500/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 $135 works out to $585/month, covering 31% of the median mortgage repayment of $1,875/month. That leaves a $1,290/month shortfall (around $15,480/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 (239 residents), interest-rate sensitivity on the $1,875 median mortgage, 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.
