The Under-Construction Discount: Is It Worth the Risk?
Under-construction properties in India typically offer 15-25% price discounts over ready-to-move equivalents. But this discount comes with real risks: construction delays, builder defaults, GST liability, and opportunity cost of capital locked up without rental income. In 2026, the calculus has shifted thanks to RERA enforcement and changing GST rules.
The Numbers: UC vs RTM Comparison
| Factor | Under-Construction | Ready-to-Move |
|---|---|---|
| Price discount | 15-25% below RTM | Market rate |
| GST applicable | 5% (no ITC) for non-affordable; 1% affordable | Zero GST |
| Rental income start | 2-4 years from purchase | Immediate |
| Builder risk | MEDIUM-HIGH | Zero |
| Capital appreciation during build | 5-15% if builder delivers on time | Starts from Day 1 |
| Loan interest during construction | Pre-EMI (interest only) | Full EMI |
| Stamp duty | On agreement value | On higher of agreement/circle rate |
Scenario Analysis: ₹60L Property
Under-Construction (30-month delivery)
| Component | Amount |
|---|---|
| Purchase price | ₹48L (20% discount on ₹60L RTM) |
| GST (5%) | ₹2.4L |
| Pre-EMI interest (30 months) | ₹6.8L |
| Lost rental income (30 months) | ₹4.5L (₹15K/month) |
| Total effective cost | ₹61.7L |
| Property value at possession | ₹60-66L (if 10% appreciation) |
Ready-to-Move
| Component | Amount |
|---|---|
| Purchase price | ₹60L |
| GST | Zero |
| Rental income (30 months) | +₹4.5L |
| Total effective cost | ₹55.5L (₹60L - ₹4.5L rental) |
| Property value after 30 months | ₹66-72L (if 10% appreciation) |
Result: In this scenario, RTM is ₹6.2L cheaper on a total-cost basis and provides certainty of possession.
When Under-Construction Makes Sense
- Reputed builder with proven track record: DLF, Godrej, Prestige, Sobha — builders who deliver 80%+ of projects within 6 months of committed date
- Significant discount (20%+): Below 15%, the risk-reward doesn't justify
- Appreciation corridor: Infrastructure catalyst expected during build period (new metro, airport)
- Long-term hold: If you're holding 7-10 years, the 2-3 year delay is proportionally less impactful
When RTM Is the Clear Winner
- Any builder without a proven delivery track record — the default risk cancels any discount
- Yield-focused investment — you need rental income from Day 1
- Cities with builder trust issues — Noida, Greater Noida (always buy delivered)
- Budget under ₹50L — at this price point, even small delays have outsized impact on returns

| Pune | UC from Godrej/Kolte-Patil | Reliable, good discounts |
| Chennai | RTM preferred | Local builders have mixed records |
| Gurgaon | UC from DLF/Godrej/Sobha only | Trust premium justified |

The Bottom Line
In 2026, the under-construction vs ready-to-move decision is primarily a builder trust decision. From top-5 national developers, under-construction at 20%+ discount is a reasonable bet. From everyone else, ready-to-move eliminates the largest risk factor in Indian real estate.
