Long term private accommodation is the most popular choice of accommodation amongst NP’s international student population.
There is usually a wide range of rental properties; conveniently accessible online resource listings of properties currently available.
As ISS does not inspect the properties, rental accommodation should only be arranged once you have arrived in Singapore, such that you are allowed the chance to inspect properties and meet potential housemates (for shared accommodation and units). It can also be an added advantage to read through a few rental listings prior to your departure; so that you can start becoming acquainted with local prices, facilities and amenities.

Remember you are not alone, after considering the cost, location, and type of accommodation, you are ready to begin inspecting properties
