This video discusses the mortgage crisis in Australia, highlighting that Westpac is revolutionizing the financial stress test protocols to provide relief for homeowners seeking to refinance their loans. Many borrowers who secured mortgages at record low interest rates during the pandemic now face significant increases in their repayments due to the expiry of fixed interest rate terms. Westpac's revised policy, to be introduced this week, will modify the serviceability requirements for borrowers looking to refinance, demanding a credit score above 650 and proof of timely mortgage repayments over the last year. The video also offers advice for homeowners on how to save on their mortgage by refinancing or renegotiating, and points out the possibility of obtaining cash incentives from lenders for moving their mortgage.
