The body of the 49-year-old woman, identified in the media as Vesna Crnobrnja, was found with multiple facial injuries in the yard of the Flame Tree Street property just after midday on Monday.
Detective Inspector Dean Johnstone said police had been called to the home previously.
"The information we have been provided so far by witnesses is that there was an altercation, and the male and the female were involved in an argument," he said.
Police are investigating whether a gardening tool was used in the attack.
