 Under the current sales schemes, successful applicants for new BTO flats typically have to wait several years before moving in while the flats were built, since the commencement of construction can only occur when the BTO successfully attains 65~70% sales.Applicants who wish to move in immediately or earlier thus have to participate in the SBF exercise (although some flats may still be under construction) or go for Resale Flats.Buyers are also subject to a set of eligibility conditions.
