I've worked in this region before and like anywhere, it's about risk management. You need to review the quality, track record and credibility of the developer, local partners and any banks involved and consider your 'use' intention (ie. residence, long term let or short-stay 'Airbnb' style returns). Critically, will the capital value difference between investing 'off the plan' be so great, that it far surpasses the risk of buying an already completed apartment building. With excellent growth in some parts of CES, it's a case of higher risk, higher potential returns - hence risk manage!
