The base price on the brochure is rarely the price you pay. By the time an Indian apartment buyer gets the keys, the cheque has typically swelled by 18% to 22% over the headline "all-inclusive" rate. Most of that gap is invisible on the cost-sheet because builders quote BSP (basic sale price) and stay quiet on the rest.
This is the buyer guide we wish someone had handed us on day one. Every number below comes from current rules (2026), live builder cost-sheets, and the Brickplot dataset of 1,800+ project audits.
How a Rs 1 crore flat actually costs Rs 1.18-1.22 crore
Take a 2BHK in Whitefield Bangalore quoted at Rs 1 crore "all-inclusive". Here is what the final cheque looks like once every line item is added back:
| Line item | What it costs (typical) | On Rs 1 cr base |
|---|---|---|
| Basic Sale Price (BSP) | Quoted rate x super built-up | Rs 1,00,00,000 |
| GST (under-construction, no ITC) | 5% on BSP (1% if affordable) | Rs 5,00,000 |
| Stamp duty + registration | 5-7% (varies by state) | Rs 6,30,000 |
| Preferential location charge (PLC) | Rs 100-300 per sq.ft. | Rs 1,80,000 |
| Floor rise | Rs 25-75 per sq.ft. per floor | Rs 1,20,000 |
| Covered car parking | Rs 3-8 lakh per slot | Rs 4,00,000 |
| Club membership (one-time) | Rs 1.5-4 lakh | Rs 2,50,000 |
| Maintenance corpus / sinking fund | 12-24 months MCS upfront | Rs 1,20,000 |
| Electricity + water + gas connection | Rs 50,000-1.5 lakh | Rs 80,000 |
| Legal + documentation | 0.3-0.5% of value | Rs 40,000 |
| Total cheque written | Rs 1,21,20,000 |
That is a 21.2% premium over the quoted price. And we haven't touched recurring monthly costs, property tax, or interior fit-out yet.
The 14 charges builders rarely lead with
1. GST on under-construction property
5% on the BSP (no input tax credit since April 2019). Affordable housing is 1%. Ready-to-move flats with OC attract zero GST — one of the biggest hidden swings between RTM and under-construction.
2. Stamp duty and registration
Highest in Maharashtra (6-7%), Karnataka (5.6%), Tamil Nadu (7% + 1% reg). Some states cut 1% for female buyers. Full state-by-state guide here.
3. Preferential location charge (PLC)
Levied for corner units, park-facing, pool-facing, vastu-compliant directions. Rs 100-300 per sq.ft. is normal in tier-1 cities. Rs 500+ is gouging.
4. Floor rise premium
Rs 25-75 per sq.ft. per floor above 5th floor in most towers. A 20th-floor unit can carry Rs 8-15 lakh in floor rise alone on a 1,200 sq.ft. flat.
5. Covered car parking
RERA technically prohibits charging for stilt/open parking as separate cost, but builders price it into "amenity charges" or sell covered slots openly. Bangalore: Rs 3-5 lakh. Mumbai: Rs 6-10 lakh. Gurgaon: Rs 5-8 lakh.
6-9. The fee stack: club, corpus, connection, legal
Club membership one-time fee is non-refundable even if you sell in year two. Maintenance corpus is held by the builder until the RWA is formed — ask for the AOA handover timeline in writing. Electricity-water connection charges are state utility deposits the builder collects as pass-through. Legal/documentation fees vary; insist on a line-item invoice.
10. TDS on property purchase
If sale value exceeds Rs 50 lakh, the buyer must deduct 1% TDS (Form 26QB) and remit to the government. Many buyers miss this and face a 1% penalty plus interest.
11-14. The recurring costs nobody totals
- Property tax: 0.15-0.50% of UAV per year (BBMP, MCGM, etc.)
- Maintenance charge (MCS): Rs 3-7 per sq.ft. per month — Rs 50,000+ per year on a 1,200 sq.ft. flat in a mid-premium project
- Society/clubhouse running fees: Rs 500-2,000 per month extra in premium gated communities
- Home insurance + content insurance: Rs 8,000-15,000 per year, often skipped
Three negotiation tips that actually work
- Ask for a full cost-sheet on day one — not just BSP. If the sales team hedges, that itself is a signal.
- Refuse to pay PLC + floor rise on the same unit twice. Many builders stack both. PLC should be locational; floor rise is vertical. Negotiate one down.
- Get the maintenance corpus held in escrow. Builders pocket the interest for 2-4 years until RWA handover. RERA Section 11 allows demanding escrow placement.
The Brickplot lens
Our 11-axis scoring formula already builds total-cost-of-ownership into Axis 7 (Value & Price Trajectory, weight 9). Any project where the all-in cost crosses 22% over BSP gets flagged for value erosion. Check the Brickplot score for the project you are considering →
Buying a flat is a five-cheque commitment, not one. Build the full P&L before you sign the booking form — not after possession, when you have no leverage left.
