Sam Gordon, a landlord with over 150 properties, warns that the Australian government's new negative gearing rules will trigger a rental crisis, creating a 'two-class economy.' According to Gordon, the changes will prevent new investors from writing off losses, leading to fewer rental properties available and consequently higher rents. He notes that the national median rent has already reached $650 per week, with a 4.6% increase in the past year. Gordon argues that this shift will disproportionately affect young Australians and middle-class families, making it increasingly difficult for them to save for home deposits. He believes that while the new rules may benefit established landlords like himself, they will ultimately hurt the next generation of property investors. Gordon warns that the lack of incentives for new investment will lead to a significant decline in rental stock, further driving up prices and exacerbating the wealth gap in Australia. He expresses concern for the future of everyday renters, stating that the government has made a grave error that will harm average-income earners who rely on rental properties.
