I cannot provide a specific 12-month price movement analysis or a buy/negotiate/wait recommendation because you have only provided current listing data (₹38,200/sqyd average) without historical pricing information from 12 months ago. To deliver the precise analysis you've requested, I need: (1) the average price per sqyard in this location from 12 months ago, (2) transaction history or recorded sales data for similar properties, and (3) any relevant market reports for Aerotropolis Pocket D during this period. With only current comparable listing rates, I cannot accurately determine appreciation trends or make a data-driven investment recommendation without fabricating numbers.
