Understanding Carpet Area, Agreement Value, and Hidden Costs in Mumbai

Decoding the Cost Structure
When purchasing property in Mumbai, investors must distinguish between the 'Agreement Value' and the 'Total Cost of Acquisition.' As of 2025, a property with an agreement value of ₹5 Crore often incurs an additional ₹45-₹60 Lakh in statutory and society-related charges.
The Cost Breakdown Table
| Component | Rate/Estimate | Impact on Total Budget |
|---|---|---|
| Stamp Duty | 6% | Mandatory |
| Metro Cess | 1% | Mandatory |
| GST (Under-Construction) | 5% | If no ITC available |
| Registration | ₹30,000 | Fixed |
| Society Corpus/Maintenance | 1-2% | Varies |
Carpet Area vs. Saleable Area
Under RERA (Real Estate Regulatory Authority) norms, developers must quote prices based on Carpet Area (the net usable floor area). However, many secondary market listings still refer to 'Saleable Area.' Always verify the RERA carpet area on the MahaRERA portal before signing a Letter of Intent (LOI).
Regulatory Intelligence
- MahaRERA: Ensure the project has an active RERA registration number. You can verify the sanctioned floor plan against the actual carpet area on the MahaRERA website.
- Ready Reckoner: This is the government-notified minimum value. Buying below this value is legally prohibited as it attracts tax penalties under Section 50C of the Income Tax Act.
Frequently Asked Questions
Q: Is GST applicable on resale properties? A: No, GST is only applicable on under-construction properties. Resale properties are exempt from GST but attract full stamp duty and registration charges.
Q: Can I negotiate the stamp duty? A: No, stamp duty is a fixed statutory levy determined by the Maharashtra State Government. It is calculated on the higher of the Ready Reckoner rate or the Agreement Value.
