Why should I try to save 20% deposit instead of 5%?

Short answer: No 1% premium, better rates, less total interest, price fall buffer.

What this actually means in plain English

With 20% deposit you avoid the First Home Loan premium, get better interest rates, pay less total interest, and have a buffer if house prices fall. On a $600,000 house, 20% deposit saves you about $5,700 per year in premiums alone. Over 30 years, that is $171,000 less paid.
