Ready to Move vs Under Construction Luxury Flats in Jaipur
Should you buy a ready-to-move luxury flat in Jaipur or book in an under-construction project? Each route has clear advantages. This guide compares them on cost, risk, choice and timing, so you can decide what fits your family.

Should I buy a ready to move or under construction luxury flat in Jaipur?
Ready-to-move flats avoid GST and let you inspect the exact home, but choice is limited. Under-construction flats offer more floors and layouts and a staggered payment plan, with delivery depending on the developer and RERA timelines. In Sankalp’s portfolio, The Index is ready to move and Spectrum 21 is under construction.
| GST on ready (with CC) | Nil |
|---|---|
| Payment plan | Staggered for under construction |
| Spectrum 21 status | Under construction |
Side-by-side comparison
| Factor | Ready to move | Under construction |
|---|---|---|
| GST | Nil once the completion certificate is issued | Payable on the price |
| See what you buy | Inspect the exact flat | Sample flat, plans and specifications |
| Choice of floor and view | Limited to unsold units | Wider, especially early in the project |
| Payments | Largely upfront | Staggered with construction milestones |
| Risk | Lower delivery risk | Depends on developer record; RERA timelines apply |
| Move-in | Immediately | At possession |
When a ready-to-move flat makes sense
Choose ready if you need to move soon, want to avoid GST, or prefer to inspect the finished home. Check the completion and occupancy certificates and the society’s maintenance before buying. In Jagatpura, Sankalp’s The Index is ready to move.
When an under-construction luxury flat makes sense
Choose under construction if you want the best pick of floors, views and layouts, a payment plan spread over the build, and a brand-new building at possession. Insist on RERA registration and check the developer’s delivery record. Spectrum 21 in Vaishali Nagar is under construction and registered under RAJ/P/2024/3261, with 2, 3, 4, 5 BHK and 7 BHK sky villas.
Checks for either route
- RERA registration and the promised possession date (verify on rera.rajasthan.gov.in).
- Carpet area in the agreement, not only super area.
- All-in cost including GST (if any), stamp duty and registration (calculator).
- Title, approved plans and, for ready homes, the completion certificate.
