Homes in this project
Price note: Keystone project page FAQ: '3 BHK configuration is priced from approximately ₹3.06 crore onwards (verify current pricing with the sales team)'; 4 BHK 'priced higher' with no figure; inclusions not stated for the figure; checked 18 Oct 2026
Each price is marked with where it came from and, where the source says, what it includes. Unless marked all-inclusive, listed prices may leave out GST, stamp duty, registration, parking, club and maintenance charges. Ask the builder for the full cost in writing.
EMI from about ₹1,99,200 a month*
*An illustration, not a loan offer or financial advice: the largest loan RBI rules allow on the lowest listed price (75% of the price for loans above ₹75 lakh, 80% from ₹30 to 75 lakh, 90% up to ₹30 lakh), at an assumed 8.5% a year over 20 years. The rest of the price, stamp duty and registration come from your own money. Your bank's rate, fees and terms will differ. Work out your own EMI.
What you'll actually pay
The listed price plus GST and government charges, for a man buying. Builder charges such as parking and club fees aren't public, so they stay a gap to ask about.
- Listed price (builder)
- ₹3.06 Cr
- GST
- ₹15.3 L (5%)
- Stamp duty and registration
- ₹15.8 L to ₹21.9 L
- Builder charges
- Not public: ask for the cost sheet
The source doesn't say what this price includes, so GST is added. It may already be in the price.
A woman buying alone would pay about ₹6.1 L less in duty.
- Floor rise and preferred location charges
- Car parking
- Club membership
- Maintenance deposit and corpus fund
- Legal and documentation fees
Haryana rates for a man buying: 7% stamp duty inside the Municipal Corporation of Gurugram or 5% outside it, plus a registration fee set by value band (₹50,000 above ₹90 lakh). Duty is charged on the higher of the price and the government's minimum value for the property, so it can come out higher. GST is 5% on a flat bought before its completion certificate, or 1% on an affordable one (up to ₹45 lakh, with carpet area within 60 sq m), and none once the certificate is issued. How these charges work. General information, not legal or tax advice: confirm the figures with the builder and the sub-registrar.
