A Bengaluru buyer in 2026 stood between two flats on the same road. One was ready, keys in hand, but priced noticeably higher. The other was two years from completion, cheaper on paper, but carried GST and a wait. The choice between an under construction home and a ready to move one is not simply about price, and the cheaper sticker does not always win once tax, waiting, and risk are added in. Getting this decision right starts with seeing the full cost and the full trade off, not just the number on the brochure.

The short answer. A ready to move home with a valid occupancy certificate carries no GST and no construction risk, but usually costs more, often ten to twenty percent above a comparable under construction flat. An under construction home is cheaper on the base price, yet attracts GST and the risk of delay, while giving you RERA protections during the build. The right answer depends on your timeline and your appetite for risk: buy ready if you need certainty and possession now, consider under construction if you can wait and want to save on the base price.

The real difference is timing, and everything else flows from it. A ready to move flat is complete, typically with an occupancy certificate, so you can inspect exactly what you are buying and move in or rent it immediately. An under construction flat is bought before completion, funded in stages as the building rises, and handed over on a future date. That single difference in timing drives the gap in price, the tax treatment, the risk you carry, and the protections available to you. Understanding that the two are not just early and late versions of the same purchase, but genuinely different propositions, is the key to choosing well.

How does GST change the maths?

GST is one of the biggest hidden swings between the two options. An under construction home attracts GST, broadly one percent for affordable housing and five percent otherwise, charged without input tax credit for the buyer. A ready to move home that has received its occupancy certificate is exempt from GST, because the sale is of a completed property rather than a service of construction. This is why the comparison is never base price against base price. A cheaper under construction flat plus GST and construction period interest may still undercut a pricier ready flat, or it may not, depending on the exact numbers, which is why you should compute the full outlay for each.

How do the prices really compare?

On price, ready to move flats generally sit ten to twenty percent above comparable under construction ones, reflecting immediate possession and a finished product you can assess. But the base price is only part of the story. For an under construction home, add the GST and the interest you pay during construction, whether pre EMI on a disbursed loan or the opportunity cost of your own money locked in while you also pay rent elsewhere. For a ready home, the higher price is offset by zero GST, no waiting, and the ability to earn rent or save rent from day one. Only when you total these does the true cost of each become clear.

What are the risks of buying under construction?

The main risk of an under construction home is delay, and in the worst cases, a stalled project. Your money goes in before the home exists, so you depend on the developer delivering on time and to the promised specification. RERA reduces this risk by requiring registration, ring fencing most of your money in a project account, and entitling you to compensation if possession is delayed, but it does not eliminate it. You also buy from a plan and a sample flat rather than the finished article, so the layout, light, and finish can differ from what you imagined. These risks are manageable with a registered project and careful checks, but they are real and belong in your decision.

There is also a cash flow dimension that catches buyers out. While an under construction home is being built, you often pay in stages linked to construction milestones, and if you have taken a loan you may pay pre EMI interest on the amount disbursed so far, all while still paying rent on your current home. That double outflow, EMI or interest plus rent, can strain a budget for two or three years even when the headline price is lower. A ready home ends that overlap immediately, since you move in and the rent you were paying simply stops. Weigh this monthly reality, not just the one time price, when you compare the two.

What are the advantages of ready to move?

The biggest advantage of a ready to move home is certainty. You see the actual flat, its light, its finish, and its surroundings, before you pay, and you take possession immediately with no waiting and no delay risk. There is no GST when the occupancy certificate is in place, and you can move in or let it out at once, turning the home into a residence or an income from day one. The trade off is the higher price and a smaller choice of units in a completed project, since the best flats are often sold during construction. For a buyer who values seeing what they buy and needs a home now, these advantages are decisive.

A ready home also lets you judge things a plan can never show. You can visit at different times of day to check the light and the noise, meet a few residents, test the water pressure and the mobile signal, and see how the common areas are actually maintained rather than how a brochure renders them. These lived details often matter more to daily happiness than the specification sheet, and they are only fully knowable in a finished building. For many buyers, the chance to buy what they have actually experienced, rather than what they have been promised, is worth a meaningful part of the price premium.

Which should a Bengaluru buyer choose?

Which to choose depends on your timeline, your risk appetite, and what you need the home to do in the next year. If you need to move in soon, want to see exactly what you are buying, and prefer certainty over savings, a ready to move flat with a valid occupancy certificate is the safer route. If you can wait, want to save on the base price, and are comfortable relying on a registered project's protections, an under construction home can make sense. There is no universally right answer, only the one that fits your circumstances once you have compared the full cost and the risk of each. A young family renting nearby and needing to move before a school term may value certainty far more than a buyer with time and a secure current home, who can afford to wait and capture the lower base price.

Your under construction versus ready to move checklist

Work through these seven steps before you decide.

1. Compute the full cost of each, including GST and construction period interest.
2. Confirm a ready home has a valid occupancy certificate for the GST exemption.
3. For an under construction home, verify the RERA registration and timeline.
4. Factor in rent you will pay while waiting for an under construction flat.
5. Assess your own need for immediate possession against savings.
6. Inspect the actual flat if ready, or the sample and plan if not.
7. Match the choice to your timeline and comfort with delay risk.

Where do you check the details that decide it?

Check the two details that most affect the maths: the GST treatment and the occupancy certificate. Our guide to GST on under construction property explains what you pay and why a ready home is exempt, and our guide to the occupancy certificate versus the completion certificate shows how to confirm a ready home is truly complete and legal to occupy. Whether you lean toward a finished flat or an under construction home in a project such as Eaton Park at Prestige City on Sarjapur Road, the decision is sound only once you have compared the true total cost of each.

Frequently asked questions

Is GST charged on a ready to move flat?

No, not when the flat has a valid occupancy certificate. A ready home with its occupancy certificate is treated as a completed property and is exempt from GST. An under construction home attracts GST, broadly one percent for affordable housing and five percent otherwise, without input tax credit. This exemption partly offsets a ready home's higher base price.

Why is a ready to move flat more expensive?

A ready to move flat usually costs ten to twenty percent more than a comparable under construction one because it offers immediate possession, a finished product you can inspect, and no construction risk. That premium is partly balanced by the absence of GST and rent saved from day one, so compare the full cost, not the base price alone.

Is an under construction flat riskier?

Yes. An under construction flat carries more risk, mainly delay or, rarely, a stalled project, because you pay before the home exists. RERA reduces this by requiring registration, ring fencing most of your money, and entitling you to compensation for delay, but does not remove it. Buying only a registered project and checking the developer's record help manage it.

Which is cheaper overall, under construction or ready to move?

It depends on the exact numbers. An under construction flat has a lower base price but adds GST and construction period interest, while a ready flat costs more upfront but carries no GST and no waiting. Often the lower base price outweighs the GST, but not always. Total the full cost of each before deciding which is cheaper for you.
