The Gold Coast’s housing affordability is diminishing with apartment sales growing to its highest figures in over 8 years, as people move to the area from other Queensland cities and interstate.

Urbis, a property and real estate research firm, said figures have doubled over last year’s first quarter with over 742 apartments sold.

The firm notes the recent boom is starting to price out local purchasers and the city will need to investigate affordability and supply issues for locals.
