Frequently Asked Questions

Can I buy a house with no deposit?

Not directly, but a guarantor loan allows a family member to use their property equity as security, effectively covering your deposit. You don't need your own savings, but the guarantor takes on risk.

Is it better to wait for 20% or buy with 5%?

It depends on the market. If property prices are rising 5–7% per year, waiting to save an extra $100,000 may cost you more in price increases than the LMI you'd pay now. In flat or falling markets, waiting to avoid LMI can make sense.
