Singapore's a fairly good place to invest in, but not in residential property for the moment. Prices are moving sideways for residential properties as there is ample supply of residential units in the market. And there are new launches on the way for residential units.
To buy-and-let approach you have to make prudent choices on the property to invest in. Opportunities are still available for buy-to-renovate, lease and sell later is too much of a hassle for foreign investors like yourself.
I recommend going for commercial and industrial properties that have good rental yields.
