Purva Northern Lights maintenance charges are planned to be clear and easy to understand. The first-year advance CAM is set at ₹70 per sq. ft. per year. After possession, residents may pay around ₹5 to ₹6 per sq. ft. per month, based on apartment size. Charges can be calculated per square foot, shared equally, or through a hybrid method with a fixed base fee plus extra costs for larger homes or premium amenities. This system helps keep maintenance fair for all residents.
