How do I build up my security deposit?

Contributions towards your security deposit are built in to your fortnightly OwnHome payments.

Every time you make a payment with OwnHome, about a third goes towards your security deposit. Each year, you save an additional ~2.5% of your home. So, after 5 years, you will have roughly 13.5% of security deposit: 12.5% of security deposit contributions via fortnightly payments, plus the 1% you contributed before you moved in.
