6,288 residents places South Grafton squarely in the middle of the New South Wales suburb size distribution (state median 5,325), with market depth comparable to most NSW localities. South Grafton's median household income of $50,700/year is 48% below the New South Wales suburb median ($97,552) — this is an affordability play where returns lean on yield and patient capital growth rather than demographic premium. Median weekly rent of $280 equates to $1,213/month — about 106% of the median mortgage repayment of $1,144/month — meaning rental income covers most of a typical owner's repayment and this is a genuine cash-flow suburb before tax benefits. South Grafton is 489 km from Sydney, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand.
Coastal markets benefit from lifestyle appeal but require a buffer for higher insurance and occasional weather-driven vacancies. Local rents consume roughly 29% of household income — a useful sanity check on tenant affordability.

Strong rental coverage: $280/week (~$1,213/month) covers 106% of the $1,144/month median mortgage repayment, so the shortfall sits at just $0/month. Investors targeting positive cash flow should shortlist this suburb.
With 82% houses in a 6,288-person market, renovation margins depend on individual street and aspect rather than any suburb-wide story — do comparable-sales analysis before committing capital.
