Specifically talking about sub-sale, very unlikely you will be able to pay all that using your EPF money.

Basic reason being, to withdraw money from EPF, assuming your first unit that you can withdraw direct to your personal account, you will still need many documents to be able to drawdown EPF.

you need booking receipts before S&P and loan, pay 1st time
you need S&P and loan doc to apply EPF, lawyer wont do it without you paying, pay 2nd time.

Then you may have enough doc to get EPF drawdown. If leasehold, still need to wait for Land Office consent, that will easily take weeks... not so easy my fren.

better start saving more before deciding on a purchase. If it's really so good deal, maybe consider talking to family members to get initial support?
