One of the first decisions every Kolkata home buyer faces: a new launch / under-construction flat, or a ready-to-move one? Both can be smart buys — it depends on your timeline, budget and appetite for risk. Here’s a clear comparison.
The core difference
A new launch is sold early in construction, so you wait for possession but typically pay less and get the latest design. A ready-to-move home is complete — you can move in (or rent it out) immediately, but you pay a premium for that certainty.
New launch / under-construction — the upside
- Lower entry price and the best chance of appreciation by the time you get possession.
- Staggered payments linked to construction, easing cash flow.
- Wider choice of units, floors and views early on.
- Latest layouts, amenities and specifications.
The trade-offs
- You wait for possession and may pay rent and EMI together for a while.
- GST of 5% applies (1% for affordable housing).
- Delivery depends on the developer — which is why RERA matters (below).
Ready-to-move — the upside
- Immediate possession — move in or start earning rent at once.
- No GST on completed, certificate-issued flats — a real saving.
- What you see is what you get — actual unit, light, finishes and neighbourhood.
- No construction risk and no rent-plus-EMI overlap.
The trade-offs
- Higher price and limited room for appreciation in the short term.
- Fewer units to choose from, and the building may already be a few years old.
The cost angle that often decides it
For an under-construction flat, budget GST (5%, or 1% affordable) on top of price plus stamp duty and registration. A ready-to-move flat skips GST entirely. So the under-construction “discount” is partly offset by GST — always compare the all-inclusive cost, not just the headline price.
How RERA reduces under-construction risk
West Bengal RERA registration means the project’s approvals, timelines and finances are on record, buyer funds are protected, and the developer is accountable for delays. Buying a RERA-registered new launch from a credible developer removes most of the old “will it get delivered?” worry — verify the registration on the official WBRERA portal before booking.
So which should you choose?
- Choose ready-to-move if you need to move in soon, want zero construction risk, or are paying rent now.
- Choose a new launch if you have time, want a lower entry price and stronger appreciation, and are buying from a RERA-registered, credible developer.
