A property investment risk is the possibility that a real estate asset fails to deliver expected returns or causes financial loss due to market, operational, financing, or legal factors. The main categories for Australian investors are market and economic risk, interest rate and serviceability risk, tenant and vacancy risk, property-specific risk, liquidity risk, regulatory and legal risk, and environmental risk. APRA's 3 percentage point serviceability buffer reduces borrowing capacity by roughly 20 to 25 percent, vacancy should be modelled at four weeks per year, and three to six months of holding costs should be held in accessible reserves.
