I am not a Tehrani dude so I know a little about Parand housing project. it would be better if someone that lives there explain good and bad things of these projects.
According to wiki Parand (mini city withing Tehran) hosts 250,000 people.(2022)
According to Divar.ir website (Ebay at home of Iranians) smaller apartments (less than 100 m)can be found for price of less than 16 billion rials there which is less than 40,000 USD.price of these new ones should be higher than $ 40,000
( I think)
I also would love to see their numbers
such as price of land and cost of production and hidden and not hidden subsidies and loans with it's interest rates for such projects in order to compare it with private companies (If there is such thing in Iran any more ) outcome.
