Yup, and that’s been true for a rather long time now.
Greddy88 can test all such propositions quite easily and financially sensibly, too. “Let do it! Let’s move into a private condo, now.” Sign, say, a 2 year or 2.5 year private condo lease, rent out the HDB unit, continue (or start) saving and investing prudently (in an age and risk appropriate way), and see how it goes. The bottom line is that I don’t see any reason why Greddy88 cannot satisfy his (Greddy88 is male?) non-working spouse’s request to live in a private condo. Buying a private condo, no, that financial math does not compute, but living in a private condo, sure, have fun.
After a couple years, at least three outcomes are then possible:
1. Greddy88 has saved up more than enough to remodel their HDB unit to design magazine standards, and they do that.
2. Greddy88 has saved up more funds, and the private condo market has become more attractive to buyers. Then market conditions plus the extra capital might make private condo ownership more realistic.
3. Greddy88 has saved up more funds, and they decide to buy a lovely vacation home in another country. (Although I would start with renting one and see how it goes. I don’t think it makes sense to leap into home ownership in a new environment without understanding what living in that environment is like, via rental.)
Or some combination of the above, particularly 1+3.
