The cost of renting in Brisbane is the cheapest it has been in six years, but it is still “extremely unaffordable” for pensioners and young people, a report reveals.

The latest Rental Affordability Index (RAI) shows the cost of renting in many parts of the Queensland capital has eased in the past 12 months, with the average household spending 24 per cent of their income on rent.

Yet SGS Economics and Planning partner Ellen White said that for young people and pensioners on benefits, renting is not affordable for pensioners with couples paying 40 per cent of their income, and singles 65 per cent.
