Later the lease was converted into ownership. The plot sizes were about 140 to 330 square metres. Some next-generation heirs of the teachers have sold the houses as the prices have increased about five thousand times. For example, a 200 square metre plot of land originally purchased in 1975 for about Rs.16,000 now sells for about Rs.100 to 120 million. Originally only two storeys were allowed to be built on about two-thirds area of the plot. Now five floors can be built on about 90% area of the plot. Real estate prices have skyrocketed over the years due to this and other reasons.
