1. Rent a house is a better option for me, why you want to take the risk (both interest risk and property market risk) if you are not sure you'll stay in S'pore for long? To buy a house, you also need to factor in the renovation and maintenance cost.

2. A lot of condo is not easily accessable, also you need to pay a higher management fee. If you only want to 保值, fixed deposit also achieves the same result.

3. You can sell it to pay back your mortgage or you can rent it out to collect rental and continue to pay back your mortgage.
