The "Pagadi System" is a local term used in some parts of India, particularly in Maharashtra, to describe a type of property transaction where a developer offers existing tenants an option to purchase the property at a negotiated rate. Regarding your query, the purchase rate for the extra area (60 square feet in this case) would depend on various factors, including: 1. _Agreement terms_: Check the agreement between the developer and the tenant for any stipulated rates or formulas for calculating the purchase price of additional area. 2. _Market rates_: Research the current market rates for similar properties in the same area to determine a fair price per square foot. 3. _Developer's offer_: Consider the developer's offer and negotiate a reasonable rate for the extra area, keeping in mind the market rates and the terms of the agreement. 4. _Calculation formula_: If there's no stipulated formula, a common approach is to calculate the rate per square foot based on the total area (300 sqft) and apply that rate to the extra area (60 sqft). For example: - Total area (300 sqft) purchase price: ₹X - Rate per sqft: ₹X / 300 - Extra area (60 sqft) purchase price: (₹X / 300) x 60 transaction.
