Confirmed - you can do all cash. I've a condo and HDB flat, condo is all cash.
Once your CPF hits the 50% Min sum (OA+SA+SRS = ~55k), you can get the bank (or actually lawfirm) to apply for 2nd property financing under CPF, which I did recently, thanks to some market run up and emptying my CPF into the market before buying flat earlier.
