You should be clear of the intent of buying a piece of property, be it for own use or investment purpose. If for your own stay, you should be setting out parameter based on your location and size specific requirements, such as accessibility to workplace, distance from the preferred schools you would like your children to enter. If you are buying property for investment, you will be looking at the yield and capital appreciation matters. The current residential gross yield in Singapore is 3 to 4.5 %. Currently, the studio apartments at prime areas are popular and able to fetch attractive rental close to 5%.
One thing to note is the calculation of YIELD: leasehold is most likely to fetch higher yield than freehold. Yield is the return based on purchase price: 2 similar pieces of properties holding different tenure will be likely to fetch the same rental, since the tenants will be indifferent to the status of tenure. As leasehold is of a supposedly lower purchase price, as a result it is able to give a higher return for yield.

In addition to the above, you may need to be concerned with the following which you may find useful to list it down:

1. Type of neighbourhood and community in line with your lifestyle

3. Physical durability, i.e. current construction method is definitely more durable in comparison to timber construction used in the traditional shophouse.
4. Aesthetic appeal, i.e. some projects have sleek and elegant clean look, while some going for tropical style with lots of landscaping.
5. Building reputation: designed by world known architect? or certain celebrity is staying there. With a project of greater reputation, it would normally bring more transaction with higher selling price.
