I cannot provide the specific investment growth analysis you've requested because the data provided is incomplete. To give you precise, data-driven numbers on price movement over 12 months, I would need: (1) the price per sqyard for similar properties 12 months ago compared to today's ₹41,500/sqyard, and (2) the asking price of your specific property for comparison. With only current comparable listing rates and no historical pricing data, I cannot calculate appreciation percentage or justify a buy/negotiate/wait recommendation without inventing numbers. Please provide 12-month historical pricing data for Pocket B, Aerotropolis, and I'll deliver the specific analysis you need.
