How safe it is to invest in the L-Zone welfare society projects ...

According to the Master Plan f

or Delhi-2021, National Capital Territory of Delhi has been divided into 15 planning zones. Out of these, 8 zones (A-H) cover existing Urban areas. Zone 'O' covers river Yamuna and the remaining 6 zones (J-P) are part of future Urban development.
Due to shortage of space in Delhi, the Govt has decided to develop zone 'L' which would be the largest of the 15 Zones of Delhi into a smart city. The Zone 'L' is currently rural in nature and comprises of 58 villages.
Zone 'L' would be a very promising investment destination as everything is being planned by the Govt under the master plan of 2021 (We all know how Dwarka came up in such a short span of time and the phenomenal returns the property has shown there).
Some first time developers, societies have already consolidated land in Zone 'L' and have started selling their projects/taking memberships. However, in lay-man term one should wait as there are some further approvals which are awaited for development to start in this area (since there is no government in Delhi for the last 1yr).
The current prices offered by societies or developers in 'L' zone range from Rs3400/sq ft- Rs4200/sq ft.
