Turn country screening into 'four cards', which is more reliable than comparing city rankings:
Card A: Affordability and Bubble Risk (Don't just look at the absolute value of housing prices)
What you should focus on is not 'whether housing prices are expensive', but whether housing prices relative to income and housing prices relative to rent are excessively deviated—this determines the pressure and magnitude of pullback during future adjustment periods.
Card B: Property Rights and Transaction Transparency (Determines whether you can 'safely buy, smoothly transfer ownership, and sell later')
The biggest fear for the first overseas property: complex property rights chain, slow registration, lack of information transparency, and long dispute resolution cycles.
Card C: Financing and Regulatory Environment (Determines whether leverage can be used, how much can be used, and whether interest rates might suddenly become difficult)
Many countries restrict loan risks for residents and non-residents through rules such as LTV/DTI/DSTI; changes in rules can directly affect the feasibility of your home purchase and holding costs.
Card D: Exchange Rates and Cross-border Costs (Determines the 'real monthly payment/real living expenses' you feel)
The same mortgage and property fees are easy when the local currency is stable; but during exchange rate fluctuations or increased capital flow friction, they can become long-term pressure.
It is recommended that you create a 'one-page country summary': use the above four cards to write conclusions, rather than piling up data.
