How Australian Banks Assess Borrowing Capacity

Australian lenders use the Household Expenditure Measure (HEM) or your declared expenses (whichever is higher). APRA requires banks to add 3% to the assessment rate: if applying at 6.25%, your loan is stress-tested at 9.25%.

Genuine Savings

Most lenders require 5% of purchase price held for at least 3 months as "genuine savings". First Home Guarantee (FHBG) allows 5% deposit without LMI for eligible buyers.
