I have come across a few articles in the mainstream media reporting on how young families are priced out of the property market in Sydney despite having saved vast amounts of money for a deposit.
By no means am I qualified to provide advice, but I am a chartered accountant (for whatever that's worth). Here's the only option I think you have if you're struggling as presented in the articles above.
Forget home ownership for now. Don't bother playing these games. It's a waste of your time and energy.
Rent. Rent a place in an area that is well within your budget but also has decent amenities.
Live frugally. Go through your expenses line by line and cut where necessary. Be ruthless with this.
Maximise income as much as possible. This can be in the form of finding a better paying job, negotiating higher wages or building a side hustle online.
This all sounds very normal and vanilla. It may even come across as insulting your intelligence.
But here's the secret sauce.
With all that money you have saved, buy bitcoin with it. Do it, no matter what the price is, every pay cycle for 8 years. Non stop. Without fail.
If Bitcoin succeeds, happy days. If Bitcoin fails, it won't matter, because you were fucked either way.
This is your only hope.
