Would you want to migrate in the future? The cost of homes and cars in SG are just too high. HDB 99 years lease, freehold no money. Cars COE.. Nani where got money🤯?

Yes, i would, for my kids. Not for money but for the education system. It is highly stressful and hard to find good jobs due to foreign talent.
Overseas pay more but got more tax. However I think their quality of life is more relaxing, which is most important for me. I don't like a kiasu culture.

Costs of home are affordable if you make use of grants and buy within you means (non-mature/small size). I dont see what's wrong with 99-year lease. Assuming you buy at 21, it can last you till 120. Life expectancy is 80+ anways. HDB is meant for everyone to have housing and not for inheritance etc.

Is owning a car in SG a necessity? No. You can take public transport, private hire or rent a car. If you cannot afford it, then dont buy it.

Do note that these big ticket times are usually one off expenditure and daily/frequent expenses will be the one that costs most in the long run. This include food, utilities, medical bills, etc.
