Short answer: Buy before built, based on plans. Often cheaper. Risks: developer failure, quality, delays. 10% deposit typical.
You buy a house or apartment before it is built, based on the plans and showroom. It is often cheaper than existing homes. But there are risks: the developer might go bust, the finish quality might differ, and completion might be delayed. You usually pay a 10% deposit and the rest at completion. Use a lawyer who specializes in off-plan purchases.
