Hidden Charges When Buying a Flat: A ₹80 Lakh Worked Example
An ₹80 lakh base price became ₹99.3 lakh in our worked example. Here is every line that gets added between the brochure and the registry, and which ones you can negotiate.
The hoarding says ₹80 lakh. The cheque book says ₹99.3 lakh. That's what our worked example below comes to for a new 2 BHK in Greater Noida West once every line on the cost sheet is added, a 24% jump that most first-time buyers don't plan for. None of these hidden charges when buying a flat are illegal. Most are standard. They're "hidden" only because the headline price leaves them out, and the time to find them is before you pay the booking amount, not when the demand letter arrives.
The worked example: an ₹80 lakh flat
The flat has a super area of 1,000 sq ft at a base rate of ₹8,000 per sq ft. That rate sits close to the indicative median of about ₹9,000 per sq ft for Greater Noida West, worked out from projects listed on IndiProp in September 2026. The buyer is a man buying alone, with a home loan of ₹64 lakh. The charge amounts are illustrative, set at levels typical of NCR cost sheets; your builder's sheet will differ.
| Item | Basis | Amount |
|---|---|---|
| Base price | 1,000 sq ft at ₹8,000 | ₹80,00,000 |
| Preferential location charge (park facing) | ₹150 per sq ft | ₹1,50,000 |
| Floor rise (upper floor) | ₹100 per sq ft | ₹1,00,000 |
| Covered car parking | One slot | ₹3,00,000 |
| GST on the above | 5% of ₹85.5 lakh | ₹4,27,500 |
| Club membership | ₹1 lakh plus 18% GST | ₹1,18,000 |
| IFMS (refundable security) | ₹50 per sq ft | ₹50,000 |
| Maintenance advance | 12 months at ₹3 per sq ft, plus 18% GST | ₹42,480 |
| Stamp duty (Uttar Pradesh) | 7% of ₹85.5 lakh | ₹5,98,500 |
| Registration fee | 1% | ₹85,500 |
| Independent lawyer | Title and agreement check | ₹20,000 |
| Loan processing fee | Assumed 0.5% of ₹64 lakh, plus 18% GST | ₹37,760 |
| Total | ₹99,29,740 |
Stamp duty is charged on the higher of the deed value and the circle rate; this example assumes the deed value is higher. Charge levels are assumptions for illustration, not quotes from any project.
Hidden charges when buying a flat: the price sheet lines
PLC and floor rise
Preferential location charges are added for a park, pool or corner view, a road-facing unit, or sometimes simply for being in a particular tower. Floor rise is a per-sq-ft premium for higher floors, usually charged from a certain floor upwards. Both are negotiable in a slow market, and both are charged on super area, so loading raises them too. If a PLC is compulsory for the only units left, count it in the base price when you compare projects.
Car parking
Parking is often sold as a separate line, from a few lakh for a covered slot in the NCR to much more in Mumbai. Ask whether the slot is allotted by number and shown on a plan attached to the agreement. Open slots in common areas are usually allotted for use rather than owned, so find out which you are paying for.
Club membership and power backup
Many projects charge a one-time club fee and a fee for power backup capacity (per kVA). These are usually compulsory. Ask whether the club's running costs are then added to monthly maintenance, which they typically are.
IFMS and maintenance advance
IFMS, the interest free maintenance security, is a deposit meant for major repairs and is supposed to pass to the residents' association once it takes over. Ask in writing that the agreement says so. The maintenance advance is different: it's prepaid maintenance for 12 to 24 months, collected at possession, and it isn't refundable. Maintenance charges billed by a builder or agency attract 18% GST.
Taxes and government charges
GST
A flat bought before the completion certificate attracts 5% GST without input tax credit, or 1% for affordable housing (carpet area up to 60 sq m in metros or 90 sq m elsewhere, and price up to ₹45 lakh). CBIC's October 2024 clarification, following the 54th GST Council meeting, confirmed that PLC paid along with construction is part of the same composite supply and taxed at the same rate. Parking bundled with the flat is treated the same way. A ready flat with an OC, or a resale flat, has no GST.
Stamp duty and registration
This is usually the largest single addition. In Uttar Pradesh it's 7% for a man, with women getting a 1% rebate on property worth up to ₹1 crore, plus a 1% registration fee with no cap. Haryana charges 7% for men and 5% for women in urban areas, with a slab-based registration fee capped at ₹50,000. Rates differ by state, so check yours with the stamp duty calculator, or go straight to stamp duty in UP or Haryana.
Registering in a woman's name in our example would cut stamp duty by ₹85,500 in UP.
TDS isn't an extra cost
What people get wrong: they budget 1% TDS on top of the price. On a purchase of ₹50 lakh or more, the buyer deducts 1% from payments to the seller and deposits it with the tax department, now under section 393 of the Income-tax Act, 2025, reported in Form 141. It comes out of the price, not on top. But you have to do it correctly, or you'll face interest and a notice.
Loan and legal costs
Lenders charge a processing fee, and some add legal and valuation charges, all with 18% GST. Check the lender's schedule; fees vary, and some waive them in offers. More important is the down payment. RBI rules cap loans at 80% of the property value for loans between ₹30 lakh and ₹75 lakh, and 75% above ₹75 lakh. Stamp duty and registration can't be included in the value for loans above ₹10 lakh. So in our example the buyer needs about ₹35 lakh in cash, not the ₹16 lakh that 20% of the base price suggests.
An independent lawyer to check title and the agreement is money well spent. So is a small budget for the deed writer, e-stamp and sub-registrar office costs.
Costs that turn up after possession
- Monthly maintenance once the advance runs out.
- Property tax and, in some cities, a transfer or mutation fee.
- Electricity and water connection deposits, and gas pipeline connection charges.
- Interiors: wardrobes, kitchen fittings, lights and fans are rarely included, and easily run into several lakh.
How to get the full number before you book
- Ask for an all-inclusive cost sheet for the specific unit, in writing, showing every line above.
- Check which charges are optional and which are compulsory for that unit.
- Get the payment plan and see when each charge falls due; possession-linked charges come all at once.
- Add stamp duty, registration and loan costs yourself. Builders rarely include them.
Then run the total, not the base price, through the home affordability calculator and compare offers on home loans. Browse projects in Greater Noida or Noida, including ATS Pious Orchards in Sector 150, and ask each builder for the same breakdown so you can compare like with like.
