I am a single man in his late thirties and I live with my parents. However, while many of my peers are fretting over the recent cost of living increases as well as increases in interest rates, I am not worried at all. I currently have a net worth of about A$1.5 million (about US$1.04 million) mostly in ETFs and crypto. I am also very frugal. I can live off about $10k to $20k per year easily.
When most people see that I live with my parents and don't own a house, they think I am a loser, but living like a loser provides more economic security because your expenses are low. If I lose my job, I can easily only spend about $20k per year, and given I have a net worth of $1.5 million, I can live off my investments forever as my withdrawal rate is 1.3% which is highly conservative.
I pay a small rent to my parents, but even if I did not live with my parents (e.g. they force me out of the house) then I can simply live in a sharehouse, and even if I didn't want to live in a sharehouse, I could easily live overseas e.g. in Southeast Asia or Eastern Europe where there is a low cost of living. Being minimalist as well as being flexible and mobile all help in increasing your resilience.
Buying a house does not interest me. It's great to have a good house that is good quality and is fully paid off. This I think can provide economic security. My parents own a fully paid off house, and it provides them with economic stability as they don't need to pay rent, and given I live with them, I benefit from that as well. However, houses were very cheap many decades ago whereas now they are significantly more expensive. If you wanted a fully paid off house, the question is how long will it take to achieve this and what risks will you expose yourself to along the journey? Paradise is great but if the path to paradise is paved with landmines, is it worth trying to get to paradise?
For one, saving for a deposit can take a long time, and by the time you save up for a deposit and then pay off the entire mortgage, chances are you will be dead, so the security of a paid off house may never come or come way too late. In the meantime while you pay off the mortgage you are exposed to the massive risk of sudden interest rate spikes.
So in my opinion, it is not worth the stress to buy a house. Simply invest in ETFs and crypto and then live a minimalist lifestyle. Economic security is about maximising your net worth and minimising your ongoing expenses. Once you can live off less than 4% of your net worth, this is when you start to become very financially secure.
