Singapore is surely everyone’s dream land. Whether you are a couple looking for your first house or is someone planning to stay here for good, now is the time for you to understand how owning a home here works. Are you curious as to how long will it take to have your dream flat come true? The Housing Development Board (HDB) is responsible for public housing in Singapore. BTO stands for Build to Order and is a flat allocation system under HDB. Interested buyers must apply for a flat from their preferred locations and wait for it until fully constructed.
