It all begins with this simple but critical question on your journey to buying your dream home:

👉Should you choose a ready-to-move flat or an under-construction flat in Kolkata’s real estate market?

Which one will benefit you in the long run? Which option really fits where you are right now-and where you hope to be in a few years?

This determination becomes even more important if you are planning to buy a flat in Kolkata, for not only yourself, but also for your family as well. The real estate industry in Kolkata is changing rapidly, and hence, your plans must be aligned with that pace.

✅What is a Ready-to-Move Flat?

A completed property that is available for immediate Handover is referred to as a ready-to-move flat.

After completing the paperwork, you can visit the site and inspect the actual unit before moving in.

This is ideal for those who want to avoid delays, get there quickly, or start renting as soon as possible.

🔑 Key Benefits (Ready-to-Move Flat):

Immediate Possession: You can move in easily once the paperwork is complete.

✅ No Waiting Hassle:

Suitable for quick relocation or to avoid construction delays—good for you and your family.

✅ What You See Is What You Get:

The best part is you can inspect the flat with your own eyes without hesitation. This helps improve your ability to verify authenticity. The right home appears at the right time.

✅ No GST:

Unlike under-construction flats, GST is not applicable on ready-to-move flats.

✅ Rental Possibility:

If you don’t want to stay, you can rent it out immediately and increase your income source.

📌 Points to Consider:

❗Higher Price:

Ready-to-move flats always cost more than under-construction flats in the same area.

❗Less Customization Scope:

It’s not always possible to plan the design or change the interiors as per your wish.

❗Old Inventory:

These flats or apartments may not always have modern amenities or new designs.

🧱What is an Under-Contruction Flat?

An under-construction flat is simply a unit that the builders are still pounding bricks into, the scaffolding is still up, and the dust clouds are still drifting across the site. Walk the site once and you can see where the kitchen will be, where the hallway will curl, and even picture the front door swinging open one day, though that day is still a few paychecks away-most likely several months or several years, depending on how the concrete cure and the funds flow. The initial sticker price almost always dips beneath what finished units command, so buyers who jump early on a skyline that is still sketchy can snag decent value and, just maybe, watch the neighborhood bloom around them as the last walls go up.

🔑 Key Benefits (Under-Construction Flat):

  ✅ Lower Price:

Compared to ready-to-move flats in the same location, the price is much lower, which makes it easier for you to afford.

  ✅ Payment in Installments:

If paying the full amount at once is difficult, you can pay in phases through installments (as per the construction-linked plan).

  ✅ Customization:

During the construction phase, if you wish, you can design or plan the interiors of your dream flat according to your preference.

  ✅ New Project and Facilities:

There is a higher chance of getting a completely new building with various modern amenities that you can enjoy and make the most of.

📌 Points to Consider:

❗ Delay in Possession:

You may have to wait until construction is complete — in some cases, it may take several years.

❗ Risk of Delay or Unkept Promises by Builder:

There might be delays or features may not match promises if the builder is not reliable. If the builder is reputed, then you can stay assured.

❗ GST Applicable:

You have to pay GST on under-construction flats.

❗ No Real View:

You have to decide based on a presentation or sample flat. The real look can’t be confirmed until construction is complete.
