irregardless of manalysian, so long foreigner, if you want to buy landed, you need approval from the SLA unit. They are at temasek tower. there is a limitation to the size of land, something like ~10000sqft, no location restriction. once approval given by ministry of home, you can buy. if you intent to do major renovation or rebuild the house, you need another approval from SLA unit and a S$50k pledge as collatoral. I have been thru it all that's why i can tell you the specifics.
