Keystone Realtors Limited (RUSTOMJEE.NS): How It Works

• Core revenue streams: sale of residential apartments, commercial space, plotted developments and township components.
• Redevelopment focus: acquiring older assets, enhancing FAR/utilization and delivering higher-value residential/commercial inventory.
• Plotted developments: strategic land purchases to create phased plotted-sale inventory (e.g., 88-acre Kasara acquisition for ₹91 crore in 2024).
• Asset-light execution: partnerships, staged land payments and pre-sales to limit balance-sheet capital deployment.

• How projects turn into cash flow:
  • Land acquisition / JV / redevelopment rights → entitlement & approvals.
  • Construction & marketing funded through mix of equity, customer advances and limited debt.
  • Phased sales (ready-to-move/partly completed) → booking revenue and collections.
  • Commercial/retail assets leased or sold for recurring revenue or one-time monetization.
• Value drivers:
  • Redevelopment arbitrage: uplift in realizations per sq. ft. vs cost to acquire/redevelop.
  • Plotted-land margins on suburban township parcels (example: Kasara acquisition creating future plotted inventory).
  • Large pipeline (47m+ sq. ft.) enabling staged revenue recognition over multiple years.
