Mount Tomah is a smaller community of 68 — about 1% of the New South Wales suburb median (5,325) — so investors should factor in the narrower buyer pool and longer average time-on-market. Households here earn $110,500/year on average — 13% above the NSW suburb median of $97,552 — a modest premium that supports resilient owner-occupier demand. Rent of $370/week (70% coverage of the $2,275/month median mortgage) leaves a gap of roughly $672/month that a typical investor bridges with negative gearing, depreciation and capital growth. Mount Tomah is 81 km from Sydney, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand. Only 54% of dwellings are separate houses (vs 76% state median), so this is a unit-heavy market where body-corporate decisions and strata supply meaningfully shape investor returns.

The most recent census recorded a median weekly rent of $370 in Mount Tomah, equating to approximately $19,240/year in gross rental income (state median $430/week).

The median monthly mortgage repayment in Mount Tomah is $2,275, or approximately $27,300/year (vs $2,167/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 $370 works out to $1,603/month, covering 70% of the median mortgage repayment of $2,275/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 (68 residents), interest-rate sensitivity on the $2,275 median mortgage, the broader New South Wales market cycle. Each of these is covered in the Risk Factors section above with suburb-specific numbers rather than generic warnings.
