Hi, I have booked the flat 3.5 years ago in Sec. 10, Greater Noida under the affordable scheme of Greater Noida authority. Tentative cost of flats is 7.52 lac maintioned in the brochure. Now, Athority issued a letter for getting the leasd deed and also demanding 75000 for additonal incrased construction cost with other charges I.e sewer charges, registration charges, lease rent, stamp duty etc. Is this increased amount of 75000 is a genuine demanding by authority? Pls suggest me what I can do, pay or not? Thanks
