Inv: just clear one thing

My next goal is to buy a condo and rent out. Hope the rental can cover loan payment.

So in order to buy a $1M condo, I have to prepare at least $250K now, because required down payment is 20%. But actually, I won't buy at current situation, as government tries to cool down property market. So in fact, I will only buy when market down, that means when  government will release the restrictions.

So I only need to prepare about $150K, 10% down payment, at most $200K.

Still have one question about CPF, can I use up all CPF OA money to buy a house? Or a min deposit is required if I use it to pay for second house?

Do leave your comments if you know it, thanks!
