This actually represents a percentage fall in the discounted properties rented from April.
In April, that figure was nearly 30% for Sydney and more than 27% in Melbourne.
However, it should be noted that rental volume was generally much lower in those months, and the news comes after many states introduced various 'no eviction' rules during COVID-19, while short term holiday lets also flooded the long-term market.
