My fiancé and I disagrees on the affordability of resale HDB (4-rm, >70 years left, above lv6), even after the online calculators. Is it really tough/risky to own a ~700k unit with our/just my income?

Looking at your stats, definitely trying to foot a $700k unit is going to be a stretch..
Some considerations when i bought my hdb resale (tampines 20yo 4rm resale at $433k):
1. It should not have to force you to liquidate your investments such as stocks since its a home you are buying
2. Ideally, not to empty my cpf as CPF earns you a high interest.
3. Mortgage instalment covered entirely by cpf contribution of either spouse so as not to fork out additional monthly cash payment
4. Max budget of $40k for reno (not incl furniture/ home appliances)
5. Decent lease yrs remaining.. i think resale flats that at still at least 25yrs old is acceptable
6. Acceptable proximity to amenities even if its close to parents
7. Timeframe you plan to stay in the house
8. Your 5yr/10yr plan incl anticipated expenses e.g. kid, medical, car (esp when you have a baby)

I might not have covered everything i considered then, but hope it helps. Anyway do your sums not just at this moment but also in the near future.

Looking that you have other expenses such as wedding to fork out... its sensible financially to buy a cheaper resale (public transport is not that bad in SG anyways). Burdening yourselves with a expensive mortgage will in some ways restrict your lifestyle or give you less flexibility to adapt in future.

Yes too expensive,

the future is hard to predict even with S-property prices climbing.​​​
