The time you will need to wait depends on many things. The waiting time for popular areas and housing companies may be very long as these homes seldom become available and there are lots of people applying for them. The size of the home you are applying for also affects the period of time. Homes with more than three bedrooms are the least common in SATO's stock and not every property necessarily has apartments this large. On the other hand, the demand for small apartments is the highest and therefore you may have to wait for a small apartment with a lower rent for a long time.
Because a large amount of SATO rented homes are spacious 1-bedroom apartments of around 60 sq m in floor area, applicants for these face the shortest waiting times.
