Under-construction properties are almost always priced lower per sq.ft. than a comparable ready-to-move unit in the same micro-market — often by 10–20%, sometimes more for projects that are still in early launch stages. Developers price this way deliberately: early buyers take on construction and timeline risk in exchange for a lower entry price, and prices are typically raised in stages as the project progresses toward completion.
The flip side is that a ready-to-move home has a known, fixed price with nothing left to the outcome of construction. What you see is what you get, and there's no ambiguity about final specifications, layout changes, or amenity delivery.
The core risk with under-construction property is delay — and while RERA has meaningfully reduced how often this happens and given buyers real recourse when it does, it hasn't eliminated it. A project can be delayed by funding issues, approval bottlenecks, or contractor disputes, and even a RERA-compliant developer can request and receive an extended completion date under certain conditions.
Ready possession property removes this risk entirely. You inspect the actual unit, not a sample flat or a rendering, and you move in on your own timeline rather than the builder's. For buyers who need to plan around a specific event — a child's school year, an existing lease ending, relocating for work — this certainty often outweighs the price advantage of buying under construction.
This is one of the most concrete differences between the two options. Under-construction properties attract GST (currently 5% for non-affordable housing and 1% for affordable housing, without input tax credit for the buyer), charged on the base price at each installment tied to construction milestones. Ready-to-move properties — specifically those where the builder has already received the Occupancy Certificate (OC) — attract no GST at all, since the sale is treated as a transaction in immovable property rather than a supply of construction service.
This GST difference alone can materially change the effective price comparison between two otherwise similarly priced options, so always ask explicitly whether a 'ready' project has actually received its OC — a project that is structurally complete but awaiting OC can still attract GST.
Buying early in an under-construction project sometimes allows for a limited degree of customization — layout tweaks in some projects, choice of flooring or fittings, or unit-facing preference from a wider set of unsold inventory. Once a project nears completion or is ready, these choices narrow to whatever units and finishes remain unsold, with essentially zero flexibility on layout.
How much this matters depends on how particular you are about specifics like modular kitchen placement, additional wiring, or structural tweaks — for many buyers this is a minor factor next to price and timeline risk, but for some it's decisive.
If your priority is stretching your budget further and you can tolerate some possession-date uncertainty, a RERA-registered under-construction project from a developer with a strong delivery track record can offer real value — verify past project delivery timelines before committing, not just the current project's marketing promises.
If certainty matters more than saving on price — because you're relocating on a deadline, don't want to manage a long wait, or have been burned by a delayed project before — ready-to-move possession is the lower-stress choice, and the absence of GST partly offsets the higher headline price.
