Walk into two projects in the same Ahmedabad neighbourhood on the same afternoon. One is a finished building where you can stand on the balcony and hear the traffic for yourself. The other is a site office with a scale model and a promise. The second one will almost always quote you a lower number.
That gap is genuine. It is also not free money. What you are being paid for is time and risk, and whether the trade is worth it depends entirely on your cash flow, your patience and how carefully you check the developer before you sign anything.
Here is the comparison without the sales gloss on either side.
The price gap is smaller than it looks once tax enters the picture
Everyone starts with the sticker price. Very few people finish the sum.
An under-construction residential flat attracts 5 percent GST on the agreement value, with no input tax credit for you. A ready flat where the builder already holds the completion or occupancy certificate attracts no GST at all, because at that point it is treated as immovable property rather than a construction service. Resale flats are the same, zero GST.
The 1 percent concessional GST rate exists only for genuinely affordable housing, priced at 45 lakh or below with a carpet area up to 90 square metres in non-metro cities, and Ahmedabad falls in the non-metro bracket for this definition. Most flats people are actually comparing sit well outside that box.
So run it properly. If a ready flat is quoted at 66 lakh and an under-construction unit in the same pocket is quoted at 60 lakh, the headline discount is 6 lakh. Add 3 lakh of GST to the under-construction flat and the real gap narrows to about 3 lakh. Still a saving, but roughly half of what the brochure comparison suggested.
Commercial buyers should note the rule flips in one respect. Under-construction commercial space carries 12 percent GST, but a GST-registered business buying it can claim input tax credit, which changes the arithmetic completely for a working business as opposed to a pure investor.
The cost of waiting is the number most buyers forget
If you are renting today and you buy something ready, your rent stops the month you move in. If you buy something with two or three years to go, you keep paying rent while your loan disbursements begin and pre-EMI interest starts leaving your account.
Take a simple case. A 48 lakh loan on a 60 lakh flat, thirty months to possession, and rent of 18,000 a month. Over those thirty months you pay roughly 5.4 lakh in rent, on top of interest on whatever the bank has already disbursed to the builder against construction milestones. That combined burden can quietly eat the entire discount you thought you were capturing.
The flip side is real too. Under-construction payment plans are linked to construction stages, so you are not writing one enormous cheque on day one. For a buyer who is still building up savings, that staged outflow is often the only way the purchase is possible at all. A ready flat demands the full amount, registration and all, within weeks.
What you genuinely gain by buying early
Three things, and they are worth naming honestly.
You get choice. Floor, direction, corner unit, the flat that catches the morning light rather than the afternoon heat. In a ready building, whatever is left is what you get, and the good units usually went first.
You get the appreciation window. If the area is genuinely developing, and Ahmedabad’s western and north-western corridors have been for a decade, the value at possession is often above your booking price. That gain belongs to you and not to a previous owner.
You get customisation room. Small layout changes, finishes, electrical points and modular kitchen provisions are far cheaper to request during construction than to break and redo afterwards.
What you genuinely gain by buying ready
You get certainty, which is the one thing no brochure can promise you.
You see the actual ceiling height rather than the rendered one. You see how the lift lobby smells, whether water pressure on the eleventh floor is real, how much sunlight the bedroom actually receives in May, and whether the “landscaped garden” is a garden or a strip of grass beside the parking ramp. You can also talk to residents, which is the single most useful research any buyer can do and the one thing an under-construction site cannot offer.
You get to move in immediately, stop paying rent, claim the full home loan tax benefits from the first year, and avoid the possibility of a delay that pushes your plans back by a year.
Where RERA does the real work
If you are leaning under-construction, this section matters more than everything above it.
Every qualifying project in the state must be registered with GujRERA, and the registration number must appear on the marketing material. Do not treat it as a decoration. Look it up on the authority’s portal yourself and read what the developer has filed: the declared possession date, the approved layout, the quarterly progress updates and any complaints on record.
Then insist that the possession date in your registered agreement matches what has been filed with the authority. A verbal timeline from a sales executive protects you from nothing. A date inside a registered agreement is enforceable.
Check the approvals separately. Land title, commencement certificate, plan sanction from the local authority, and for taller buildings, fire and other clearances. A project that is selling hard while an approval is still pending is a project telling you something about itself.
Finally, look at what the developer has already finished. Not renders, buildings. Elite Group’s completed residential projects, from Elite Greens and Elite One13 in Gota to Elite 32 in Memnagar and Elite Ornate, are standing buildings with people living in them. Walking through a developer’s delivered work is the closest you will get to seeing the future of the project you are considering.
The middle path most sensible buyers end up taking
There is a third option that gets ignored because it does not fit neatly into either column.
Buy under-construction, but only from a developer whose finished buildings you have physically visited, in an area where the surrounding infrastructure already exists rather than being promised. That combination gives you most of the price advantage of buying early while removing the largest part of the risk, which is not construction quality so much as whether the building gets finished at all.
Ahmedabad has a clear example of this pattern in the corridor around Vaishnodevi Circle, SG Highway and Gota. The roads, schools, hospitals and retail are already there. Projects like Elite The Vision, a commercial development under construction in that belt, are being built into an ecosystem that already works, rather than into a plan for one.
A short decision guide
Lean towards ready to move in if you are currently paying rent and cannot comfortably carry rent and loan interest together, if you need the home within six months for a school admission or a family reason, if you want tax benefits starting immediately, or if you simply want to see exactly what you are buying before you commit.
Lean towards under construction if your possession timeline is flexible, if a staged payment plan is what makes the purchase affordable at all, if you want first pick of units and some say in finishes, and if you have done the RERA and track record homework properly rather than trusting a brochure.
Before you book anything under construction
Verify the GujRERA number on the official portal, not just on the hoarding. Read the filed possession date and get it into your agreement. Confirm the land title and the sanctioned plan. Ask for the payment schedule in writing and check that it is linked to construction stages rather than calendar dates. Ask for the full cost sheet including GST, parking, club charges and maintenance deposit so you are comparing like with like. Visit at least two completed buildings by the same developer.
Do those six things and you have removed most of the downside of buying early.
The bottom line
Neither choice is smarter than the other in the abstract. A ready flat buys certainty at a premium. An under-construction flat buys a discount at the price of time, and that discount only survives if you add GST and rent to the comparison and the developer actually delivers on schedule.
