Key Pollution Drivers
Local Contributors: The Indo-Gangetic plain functions like a pollution bowl, trapping pollutants in winter months.
● (Key Sources): PM2 is primarily driven by vehicles, heavy industrial activity, coal-fired power plants, and construction dust. 5 and PM10 levels.
Seasonal spike: Stubble burning in autumn and cold weather result in sharp increases in the AQI, sometimes pushing it into the hazardous range.
Note on Data: Air quality varies dramatically by season. The “Most Polluted” rank is determined by annual averages, but Punjab and Haryana, for instance, can shoot to the very top all the way up to November during stubble-burning months.
Frequently Asked Questions
What should I check during a site visit in Gurgaon and NCR?
Construction quality, water and power backup, the neighbourhood, road access, and how the actual unit compares to the brochure. Visit at different times of day if you can.
Can I negotiate the price in Gurgaon and NCR?
Resale and ready inventory are usually negotiable, while fresh launches have fixed rates but may waive some charges. Compare recent deals nearby to judge a fair price.
What is the difference between carpet area and super area?
Carpet area is the usable space inside your walls; super area adds a share of common areas. Always confirm the carpet area you actually get before comparing prices.
What extra costs come beyond the price in Gurgaon and NCR?
Budget for stamp duty and registration, GST on under-construction homes, parking, club and maintenance deposits, and loan fees. Ask for a full cost sheet upfront.
How does Realty Hunting help me buy in Gurgaon and NCR?
We share verified listings, honest area advice and the real paperwork picture, and connect you with builders and sellers. Reach out and we will shortlist options that fit your budget.
Should I buy ready-to-move or under-construction in Gurgaon and NCR?
Ready homes have no wait, no GST and no build risk but cost more; under-construction is cheaper with a longer wait. Choose by your timeline and risk appetite.
How do I book a property in Gurgaon and NCR?
Shortlist, visit, check the papers and RERA, then pay the booking amount and sign the agreement. Read the payment plan and cancellation terms before you commit.
Do I need a lawyer to buy property in Gurgaon and NCR?
For anything beyond a simple, clean deal it helps. A lawyer vets the title, the agreement and the approvals, which is cheap insurance against a costly mistake.
What is a builder-buyer agreement?
It is the core contract between you and the developer, setting the price, payment plan, area, specifications and possession date. Read it fully before signing.
What is an occupancy certificate and why does it matter?
It certifies a building is legally fit to occupy. Never take possession of a completed home without it, since it affects loans, utilities and resale.
What is mutation and why is it important?
Mutation updates the ownership in municipal and revenue records after a sale. Without it the property tax and records still point to the old owner, so get it done.
What credit score do I need for a home loan?
Lenders prefer a healthy score, usually in the mid-700s and above, for the best rates. A lower score can still get a loan but often at a higher rate.
Can I claim tax benefits on a home loan?
Yes, home-loan principal and interest carry deductions under the income tax rules, subject to limits and conditions. Confirm the current rules or ask a tax adviser.
What is the difference between freehold and leasehold?
Freehold gives you full, permanent ownership of the property and land; leasehold runs for a fixed term from an authority. Freehold is generally simpler to resell.
How do I check a builder's track record?
Look at delivered projects, delivery delays, the RERA record and buyer reviews. A builder with a clean, on-time record lowers your risk sharply.
What red flags should I watch for when buying?
Unclear title, missing approvals or RERA, pending dues, a builder with delays, and prices far below the market. If something feels rushed, slow down and verify.
