Australian working holiday visa proof of funds

I’m planning to spend a year working abroad in Australia and I need to get my visa done as my first step. My issue is that I bought a house alone last year and I really struggle with savings, so in order to take this trip I’ll need to rent my house out and move back with the parents for a while to save some travel money.
Ideally I’d like to secure the visa before I rent my house out, so I know that it’s definitely happening.

If anyone has done the visa before could you please advise me on whether you need the proof of funds for the visa process or is that something that happens when entering the country?
