House hunters have been gifted the biggest summer selection of properties to buy in a decade as Sydney’s ongoing real estate slump creates a growing backlog of unsold homes.

Sydney’s supply of properties for sale has hit a decade high this summer as weakening buyer demand creates a growing backlog of unsold housing.

New data published today showed the number of homes for sale across the city surged 11 per cent last month to hit 35,704 — the highest volume recorded over a February since 2009.

There were also nearly 10,000 more homes for sale than over February 2018, an annual jump of 14.4 per cent, according to the SQM Research figures.
