A rising number of Australians are struggling to make their mortgage payments as increasing property prices and interest rates take a bigger chunk out of homeowners’ incomes, a mortgage brokers’ association said.

About 16% of property owners struggled to repay home loans in November, up from 11.7% in May, the Mortgage Finance Association of Australia said in an e-mailed press release, citing the MFAA/Bankwest Home Finance Index, which surveyed 850 people across Australia.
