Target 1: Know your real affordability, not your optimistic one
You should already have a realistic view of income, likely CPF growth, and what flat price still feels safe if later-stage payments are heavier than expected.
Target 2: Build a meaningful cash buffer
If all your confidence comes from expected future CPF alone, you are exposing yourself to more later-stage stress. A real cash buffer gives you room when the numbers do not land perfectly.
Target 3: Understand your Key Collection risk
Before committing, you should already know how large the later-stage payment may feel, and whether your CPF pool by then is likely to be strong enough. If not, you should know how much cash would need to step in.
Target 4: Be comfortable with the monthly mortgage too
Some buyers aim for a flat that they can just about secure, but not one they can comfortably live with after move-in. That is rarely a healthy target. Long-term calm matters too.
Goal 5: Buy within your appetite, not just your ceiling
This may be the most important one. A flat at your absolute limit can turn the later stages into a high-stress gamble. A flat within your appetite gives you room to handle delays, surprises, and normal life costs with more breathing room.
