1st loan no deposit is it possible

Hi,

My wife and I are both 27 years old and we are about to buy our first property. Recently we have been in a lot of debt from our wedding and a poor business decision. We decided to get a job working in remote indigenous communities to help us pay off our debt. We have paid off about $30,000 in about 6 months and will have the other $10,000 paid off in 6-8 weeks.
I've been reading and researching property for a long time and the sooner we can get our first IP the better. We are going on holidays down south to where we will buy after christmas, I would love to buy or at least be in a position to buy or make an offer if I find something good. The only problem is we will not have a 20% deposit for around a year, but if their was a way we could get the 20% deposit or get a 100% loan we could start sooner.

My parents own around 15 properties and I could probably ask them to use the equity in one of their properties and release it as soon as possible. But if their was something I could do to avoid that it would be great.

So basically my question is, Does anyone know if you can get 100% loans or does anyone have any other ideas how I could still be able to buy a property asap.

Thank you

Michael
