Two separate reports have cemented earlier forecasts that South Brisbane is in line to benefit from strong rental and capital growth.

Your Investment Property released its Annual Top 100 Suburbs guide in August, which put South Brisbane at number one in its ranking of the best property investment destinations in Australia.

The latest statistics from both the Residential Tenancies Authority and the Real Estate Institute of Queensland now claim that South Brisbane is performing strongly.

The latter showed South Brisbane as having the tightest residential vacancy rates in southeast Queensland, with the vacancy rate falling from 1.6% to 1.5% between quarters.

A vacancy rate of 3% is considered the equilibrium point of supply and demand.

Meanwhile, Residential Tenancies Authority statistics show that average residential rents in the suburb have climbed 6% over the September quarter.
