Frequently Asked Questions

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.

What is the difference between capital appreciation and rental yield?

Appreciation is the rise in the property value over time; rental yield is the annual rent as a share of the price. Most Indian homes give modest yield and rely on appreciation.

How much should I keep as a buffer beyond the price?

Set aside for stamp duty, registration, GST where it applies, interiors, and a contingency. A buffer of a meaningful share above the base price is prudent.

Is a home loan pre-approval useful?

Yes, a pre-approved loan tells you your budget, speeds up booking and strengthens your negotiating position with sellers. Get it before you shortlist seriously.

How do I choose between two similar projects?

Compare the builder record, RERA status, carpet area, real amenities, connectivity and total cost, not just the headline price. Visit both before deciding.

What stamp duty and registration charges apply in Gurgaon and NCR?

Stamp duty and registration vary by state and are usually a few percent of the property value, with a small rebate for women buyers in many states. Confirm the current Gurgaon and NCR rate before you budget.
