You forgot to add the other sources of moolah that account to the 4970cr figure I came up with.Jubin said:this changes their budget to ~ 3100 crore still greater than last year's budget but nowhere near ~6000 crore that was published in the papers nor the ~4970 crore that you suggest.
from post #1677-
besides a loan of Rs403 crores for MUTP from the World Bank, Rs503 crores loan recovery from seven municipal corporations and 13 municipal councils which come under MMR, the Rs60-crore grant under the Jawaharlal Nehru National Urban Renewal Mission (JNNURM), Rs50 crore as contribution of MCGM and Railways towards Station Area Traffic Improvement Scheme (SATIS) and Rs721 crore through other revenue sources. According to the chief minister, the income from the sale of land will be utilised for providing the basic infrastructure facilities in MMR.
Even if they sell the remaining land for 800cr instead of 1430 as you say, still their budget will be around 4340cr.
