I'm malaysian, living in the UK right now. Used to live in KL for almost 25 years. May I know which area is the flat? 30k Euros for a flat in KL seems pretty cheap to me. The 3bed condomoniums in KL are typically ~110k Euros. Yes, you can buy a property unless if it a above a certain amount and not below.
If it's for investment purposes, I wouldn't recommend buying flats in Malaysia. Flats/Condos in Malaysia generally tends to increase in price ~1-2 years after being built, and begins a downward trend afterwards, because there is simply too much supply of flats/condos in KL area.
