Many don't dare to leverage when they are young including myself. I borrow 20k cash from my dad in 1995 for my 5 room HDB deposit. You need to first understand yourself than calculate the risk.

I took a loan of $200,000 from CPF for my 5 room HDB in 1995 for 25 years after I sold my 4 room HDB for a profit of $180,000. Use the cash to buy a 2 Bedroom in 2006 with the cash 20%. You can take the CPF out by selling your HDB and buying another but now you need to give back 50% of the profit before they loan you. This way you reduce your CPF holding too much of your Money.
Property investment is about how much you sell not how much you buy. Whether HDB or private look at future development nearby, such as school, MRT, food centre, transport. HDB resale in Marine Parade and certain mature estate are not your normal resale HDB.
