⚡ Quick Answer

What Do the Terms Mean?
An under-construction flat is one you book before the building is complete. You usually pay in instalments linked to construction stages and receive possession later.
A ready-to-move flat is in a completed building that has received its occupancy certificate (OC). You can usually move in soon after the sale is registered.
Side-by-Side Comparison
| Factor | Under-construction | Ready-to-move |
|---|---|---|
| Move-in | Later, after completion | Soon after purchase |
| What you see | Plans, sample flat and site | The actual flat and building |
| Choice of units | Usually wider - floors, views, layouts | Limited to what is left |
| Payment | In stages, linked to construction | Mostly upfront |
| GST | Applies | Does not apply (with OC) |
| Main risk | Delay or changes during construction | Fewer choices; check building condition |
| Rent while waiting | You may pay rent and EMI together | No overlap once you move in |
A general comparison. Every project is different.
Pros and Cons of Under-Construction Flats
Advantages
- Wider choice: early buyers can often pick the floor, view and layout they prefer.
- Staged payments: paying as construction progresses spreads the cost over time.
- A new building: you get the latest design, amenities and building standards when it is complete.
Points to consider
- Waiting time: you will not move in until the project is complete.
- Delay risk: projects can take longer than planned. MahaRERA rules give buyers some protection, but delays still affect your plans.
- Double cost: if you rent while you wait, you may pay rent and loan EMI at the same time.
- GST: adds to the total cost.
Pros and Cons of Ready-to-Move Flats
Advantages
- What you see is what you get: you can check the flat, light, views and finishes in person.
- Move in quickly: no waiting and no overlap of rent and EMI.
- No construction risk: the building is already complete.
- No GST on homes with an occupancy certificate.
Points to consider
- Less choice: the best units may already be sold.
- Larger upfront payment: you usually need the full amount, from savings and loan, at once.
- Condition: in older buildings, check maintenance, repairs and society records.
