Ready-to-Move vs Under-Construction Flats in Gurgaon: Price, Risk and Fit in 2026

Ready-to-Move vs Under-Construction Flats in Gurgaon: Price, Risk and Fit in 2026

A ready-to-move flat already has its occupancy certificate. You can inspect it, there is no GST on the purchase, and you can move in or rent it out soon. An under-construction flat usually costs a little more per sq ft in current listings, carries 5% GST, and asks you to wait, but you pay in stages and RERA gives you specific protections if the developer is late. Square Yards’ September 2026 data puts ready-to-move listings at about ₹14,164 per sq ft, under-construction at ₹14,800 and new launches at ₹15,150. The right choice depends on when you need the home, how your cash flow works and how much delivery risk you’ll accept, more than on the headline price.

The two options at a glance

What the 2026 price data shows

Square Yards’ September 2026 snapshot lists three statuses across Gurgaon. Ready-to-move listings average ₹14,164 per sq ft across 1,161 listings, under-construction ₹14,800 across 197, and new launches ₹15,150 across 91. On those numbers under-construction is about 4.5% above ready, and new launches about 7% above. squareyards

The gap is wider in some corridors. In New Gurgaon, 151 ready-to-move units average ₹11,300 per sq ft against ₹12,550 for 47 under-construction projects, roughly 11% more. That fits what you might expect: buyers pay more for the newest product and for the chance to buy before prices move. These are asking-price averages, not like-for-like comparisons. Ready stock includes older flats, and the mix of towers differs by status, so use them as a guide and compare specific projects.

An illustration (arithmetic only). A 1,500 sq ft flat at the Gurgaon-wide ready average costs about ₹2.12 crore. At the under-construction average it’s ₹2.22 crore, and 5% GST adds ₹11.1 lakh, for a total of about ₹2.33 crore. That is a gap of roughly ₹20.6 lakh in favour of buying ready, before any difference in quality or location.

GST and other costs

GST is the clearest cost difference. Guides for 2026 agree that GST is 1% for affordable housing and 5% for other residential flats, both without input tax credit, while ready-to-move flats with an occupancy or completion certificate, and resale flats, are exempt. Most Gurgaon flats won’t qualify as affordable, so 5% is the usual figure. That GST depends on the flat being under construction at the time you buy, and it’s the occupancy certificate that makes the difference, not the word “ready” in a brochure. elitebuild

Other costs are the same either way. Stamp duty and registration depend on the higher of your agreement value and the circle-rate value. See Gurgaon circle rates 2026-27 for the sums. Add maintenance deposits, parking and club charges, and see our guide to property taxes in Haryana. Confirm GST treatment for your specific unit with a chartered accountant.

Delay risk and what RERA gives you

The central risk with an under-construction flat is that the date slips. RERA is designed to limit that, with two main protections:

• Delay remedy. Under Section 18 you can exit with a full refund plus interest, or stay and claim monthly interest on every rupee paid until possession. In Haryana the delay interest is SBI’s highest MCLR plus 2%, about 10.8% a year in early 2026. That rate moves with SBI’s lending rate, so check the current figure. Some guides add that documented losses such as rent may also be claimed. Ask a lawyer whether that applies to you. prateekproperties, ghar

• Escrow. Developers must deposit 70% of the money collected into a dedicated escrow account, used only for that project’s construction. That lowers, but doesn’t remove, the risk of funds being diverted. expressbuildersltd

Other protections include a five-year structural warranty after possession. A regulator can enforce these rights, but a complaint takes time and the outcome depends on your agreement, so the real protection is choosing a registered project and a developer with a delivery record. Search the project on the Haryana RERA site, and read our RERA guide for what to look for. Buying a project that isn’t registered means you can’t use these remedies. ziprealtors

The cash-flow side: EMI, rent and timing

Under-construction purchases are paid in stages linked to construction progress, so you pay interest only on the portion of the loan that has been released. Ready flats usually mean paying in full, or starting full EMIs, immediately. The catch with waiting is that you may be paying rent and interest at the same time.

An illustration with a placeholder rent. If you rent for three years while waiting at ₹60,000 a month, that’s ₹21.6 lakh, which is close to the ₹20.6 lakh gap in the example above. So the apparent saving from buying under construction can vanish if you must rent while you wait. That comparison is too simple, because it leaves out loan interest, price movement and the chance of delay, but it shows why the wait matters. Ask a home loan advisor to model both routes, and ask a chartered accountant when tax benefits on home loan interest begin, because that can depend on possession.

Risks of buying ready

A ready flat isn’t risk-free either:

• The certificate. Ask for the occupancy or completion certificate and check that it covers the tower you’re buying. A project can be “ready” in marketing before the paperwork is complete, and without the certificate the GST position is different.

• Condition and age. Inspect fittings, seepage, plumbing and the state of common areas. Ask what maintenance dues are outstanding.

• Resale paperwork. For a resale flat, check the chain of title, society no-objection and the conveyance position, and have a lawyer review it.

• Waterlogging and civic condition. A finished building in a sector with drainage problems still has them. Ask residents about the last monsoon.

• Price premium. You pay for certainty, which is why ready stock tends to cost more once GST is set aside only by the amount shown above in the averages and not in every project.

Checks for both

1. Registration. Search the project on HRERA, and match the registration and validity.

2. Certificates and approvals. For ready flats, the occupancy certificate. For under-construction flats, the sanctioned plan and the construction status on the RERA portal.

3. Agreement terms. Read the possession date, delay clause, payment plan and what happens on cancellation.

4. Developer record. Check our builders directory and search for complaints.

5. Loan approval. Confirm your bank has approved the project and understand the disbursement schedule.

6. Total cost. Include GST where it applies, registration, maintenance and fit-out.

7. Premium units. Use the luxury apartment checklist for high-end purchases.

Which suits whom

• You need to move in within a year, or want rent soon: ready-to-move.

• You can’t afford a rent-and-EMI overlap: ready-to-move, or an under-construction project very close to completion.

• You have a flexible timeline and prefer staged payments: under-construction, from a registered project with a developer you’ve checked.

• You’re drawn to a new launch for its price or layout: accept the highest per-sq-ft average, a longer wait and developer risk, and test the delivery record.

• An NRI buying from abroad: ready-to-move simplifies inspection and paperwork, but a lawyer’s review matters either way.
