Quick answer: choose a ready-to-move flat if you need to live in it or rent it out soon and want to see exactly what you are paying for. Choose an under-construction flat if you can wait several years, want a brand-new building and are comfortable with delivery risk. In Bandra West, ready homes are mostly in older buildings, while new large-format homes – such as Godrej Bandra Bay at Bandra Reclamation (4 BHK, approx. 2,900–3,500 sq ft*, from ₹29 Cr*) – are bought before completion.

For most luxury buyers in Bandra West, the real choice is not just “new or old”. It is a home you can see today versus a home you are buying on paper. Each has clear advantages and clear risks. This guide walks through both, so you can decide with your eyes open.
Under-Construction vs Ready-to-Move at a Glance
| Factor | Under-construction | Ready-to-move |
|---|---|---|
| What you see before buying | Plans, sample flat, brochure | The actual home, building and neighbours |
| Move-in | After possession – often several years | Soon after registration |
| GST | Applies | Generally not applicable once the OC is received |
| Payment | In stages linked to construction | Mostly upfront at purchase |
| Main risk | Delay, changes, delivery quality | Older building, repairs, hidden defects |
| Building age | Brand new, modern specifications | Varies – often older in Bandra West |
| Legal check | MahaRERA registration, agreement for sale | Title, OC, society records, dues |
Why This Choice Matters More in Bandra West
Bandra West is almost fully built up. Most homes on the market are in older cooperative societies or redeveloped buildings, and new large-format projects are rare. This means:
- A ready flat is easy to find, but often in an older building with fewer amenities, limited parking and older services.
- A new building with large homes, modern lifts, parking and amenities usually has to be bought before it is complete.
- Large sea-facing homes in new towers come to the market only occasionally.

Advantages of a Ready-to-Move Flat
- What you see is what you get: you can check light, ventilation, view, noise and the actual carpet area.
- No waiting: move in or rent it out soon after registration.
- No construction risk: no delays or changes to the plan.
- GST is generally not charged once the building has its Occupancy Certificate.
- You meet the neighbours and can see how the society is run.
Before you take the keys to any flat, ready or new, use our possession checklist: Occupancy Certificate and snagging.
What to Watch Out For
- Age and condition of the building – structure, plumbing, lifts, waterproofing.
- Redevelopment plans – an older society may be heading for redevelopment, which can be good or disruptive.
- Pending dues, society disputes and the share certificate.
- A valid Occupancy Certificate – without it, loans, resale and utility connections can be difficult.
Advantages of an Under-Construction Flat
- A brand-new building with modern design, lifts, parking and amenities.
- Payments in stages linked to construction, rather than the full amount at once.
- Choice of unit: early buyers usually have more choice of floor, view and layout.
- Long life ahead: a new building needs fewer major repairs in its early years.

What to Watch Out For
- Delays: possession can take longer than planned. Check the developer’s delivery record.
- Changes: the final home can differ from the brochure. Rely on the registered agreement and approved plans, not marketing images.
- GST and longer holding cost: GST applies, and money is committed years before you can use the home.
- Registration: buy only in a project registered with MahaRERA.

Which Costs More: Under-Construction or Ready-to-Move?
Both types of home carry stamp duty and registration. The main difference is GST, which applies to under-construction homes but generally not to completed homes with an OC. On the other hand, an older ready flat may need renovation, and the building may need repairs sooner.
For the full breakdown on a ₹29 Cr* home, see our guide to stamp duty, GST and registration in Mumbai. If you plan to borrow, our home loan guide for luxury flats explains how banks pay out in stages for under-construction homes.
When comparing a resale flat with a new one, convert both to carpet area first – see carpet area vs built-up area explained.
Worked example: the tax difference on a ₹29 Cr* home
| Cost item | Under-construction | Ready-to-move (OC received) |
|---|---|---|
| Price (same for both, for illustration) | ₹29 Cr* | ₹29 Cr* |
| GST – effective 5%, no input tax credit | Approx. ₹1.45 Cr | Not applicable |
| Stamp duty – 6% in Mumbai (incl. 1% metro cess) | Approx. ₹1.74 Cr | Approx. ₹1.74 Cr |
| Registration fee | ₹30,000 (maximum) | ₹30,000 (maximum) |
At the same price, the ready flat saves about ₹1.45 Cr in GST. But the comparison is rarely like for like: an older ready flat in Bandra West may need a full renovation, has older lifts and services, and may face redevelopment, while a new tower comes with modern specifications. Stamp duty is charged on the agreement value or the ready reckoner value, whichever is higher, and women buyers in Maharashtra may get a 1% concession, subject to conditions.

A Simple Way to Decide
| Choose ready-to-move if… | Choose under-construction if… |
|---|---|

| You prefer paying once and avoiding GST | You prefer paying in stages |
| You are comfortable with an older building | You are comfortable with delivery risk and have checked the developer |

Frequently Asked Questions
Is it better to buy an under-construction or a ready-to-move flat in Bandra West?
It depends on your timeline and risk comfort. A ready-to-move flat suits buyers who need to move in or rent out soon and want to see exactly what they are buying. An under-construction flat suits buyers who can wait, want a new building with modern specifications and are comfortable with construction and delivery risk.
Is GST charged on a ready-to-move flat?
GST applies to under-construction homes. A completed flat that has received its Occupancy Certificate (OC) before the sale is generally not subject to GST. Stamp duty and registration apply to both. Confirm the current rules with your chartered accountant.
How can I reduce the risk of buying an under-construction flat?
Buy only in a project registered with MahaRERA, check the developer’s delivery record, read the registered agreement for sale carefully, pay according to construction stages and keep every receipt. Never pay large sums before the project is registered and an agreement is signed.
What is an Occupancy Certificate and why does it matter?
An Occupancy Certificate (OC) is issued by the local authority when a building is completed as per approved plans and is fit to occupy. Without an OC, you may face problems with water and electricity connections, home loans and resale. Always ask for the OC before buying a “ready” flat.
Is Godrej Bandra Bay under construction or ready to move?
Godrej Bandra Bay is a pre-launch project. MahaRERA registration is awaited and the possession date is not yet confirmed, so it is neither ready to move nor formally launched yet.
Are there many new ready-to-move luxury flats in Bandra West?
New supply in Bandra West is limited because the area is almost fully built up. Most ready homes are in older buildings or redevelopment projects, which is why new large-format projects attract attention.
