I saw this large billboard poster on the wall of Imamzadeh Saleh in Tajrish. It says that the Ministry of Charity in Shemiran would like to renting out it's 23 donated shops and places to whoever interested in.
Based on the space (square meter) and it's location the rent would be different.
The small size area is 0.85 square meter, located in the begining of Ghaem Bazar with 7,000,000 Rials (7 X 1,000,000 Rials) (700,000 Tomans) rent per month.
The Largest one has 316.14 square meter located under the Takieyeh with the rent price of 80,000,000 Rials (80 X 1,000,000 Rials) (8,000,000 Tomans) rent per month.
