Apart from the staggering price tags attached to these projects, one has to shell out significantly on monthly maintenance. Get a clear estimate about what you would pay every month. Go ahead only if you're comfortable with a lifetime of making that payment. Rahul Purohit, National Sales Head, Square Yards gives a sense of monthly outflows: “For instance, the average maintenance charge in most luxury projects in Gurgaon is around Rs 4.5/sq ft. This means, if you own a 5-BHK penthouse in DLF Magnolias sized around 10,000 sq ft, you will end up paying close to Rs 45,000-55,000 a month as maintenance. For a 4-BHK in DLF Crest of around 3,500 sq ft, maintenance amounts to Rs 15,000-16,000. The charges in Noida are much lower as it is a relatively affordable market. The average charge hovers around Rs 3/sq ft. For instance, in ATS Hamlet, one of the most premium projects in the city, monthly maintenance varies from Rs 5,300-9,400. Cleo county with unit size ranging from 1,618-2,448 sq ft, the maintenance is Rs 2.65 including GST.” In a regular group housing society, the maintenance is computed at the rate of 2- 2.5 Rs/ sq ft, while in premium it is 5-6 Rs/sq ft and in certain cases it may be Rs 8-10/sq ft.
