💡 The offset account: the best emergency fund for homeowners
If you have a variable rate mortgage, every dollar in an offset account saves you your mortgage rate in interest (currently ~6%). This is a guaranteed, tax-free return of ~6% — better than any savings account. If you have a mortgage, your offset account should double as your emergency fund.
