In a festival gift, MMRDA approved the long-pending 24-km Kharghar-Ghatkopar metro extension on 17-Oct-2025 with an estimated ₹4,800 Cr outlay and 5-year completion target. Once operational, Kharghar to BKC commute will shrink to 45 min from 95 min currently. Historical data shows prices within 1 km of metro corridors jump 12–15% during construction and 25% on commissioning. Micro-markets to watch: sectors 15, 34, 35 & 36 Kharghar, where 22,000 under-construction units will benefit. We estimate ₹8,000 Cr incremental market-cap for residential inventory. Risk: land acquisition in Taloja creek stretch may delay Phase-2. Keywords: Kharghar metro extension, Ghatkopar connectivity, property price impact.
