Two buyers looked at flats in the same Sarjapur Road micro market in 2025. One paid a premium for a finished flat with keys in hand and moved in that month. The other booked a similar unit still under construction for noticeably less, but agreed to wait two years, pay GST, and carry the risk of delay. Neither made a mistake. They simply had different needs: one wanted a home now, the other wanted to save money and could wait. The right answer here was personal, not at all universal.

Ready to move and under construction are the two basic choices a Bengaluru buyer faces, and each comes with its own price, tax, and risk profile. This guide lays out the real differences, including how GST applies, what the price gap really means, and how to decide which suits your situation.

The short answer. A ready to move flat with a valid occupancy certificate attracts no GST and gives you immediate possession, while an under construction flat carries GST, at 5 percent for standard homes and 1 percent for affordable ones, but usually costs 10 to 20 percent less, as a GST comparison by NoBroker sets out. The trade-off to remember: under construction can save you money and let you pay in stages, but it brings delay and delivery risk, while ready to move costs more and removes that risk entirely. Which wins depends on your timeline and your appetite for risk.

How does GST differ between the two?

Under construction flats attract GST, while a ready to move flat with an occupancy certificate does not. For a standard residential under construction flat the rate is 5 percent, and for an affordable home it is 1 percent, where affordable means a carpet area up to 60 square metres in a metro and a value up to 45 lakh. A ready to move property, once its occupancy certificate has been issued, is treated as a completed asset and is exempt from GST altogether.

There is a nuance worth knowing on the under construction rate. GST is charged after a standard deduction for the land portion, so the effective rate a buyer pays is lower than the headline 5 percent, working out to roughly three and a half percent of the total on a typical flat. Even so, the tax is real money: on an eighty lakh under construction flat it runs to well over two lakh rupees. The point is not that GST is trivial, but that it needs to be weighed against the lower base price rather than looked at on its own.

What does the price gap really mean?

Under construction flats typically cost 10 to 20 percent less than a comparable finished flat in the same micro market. That discount usually outweighs the 1 to 5 percent GST, so on pure numbers an under construction unit is often the cheaper way in. You are, in effect, being paid a discount for taking on the wait and the risk that the finished buyer does not have to bear.

But the saving is not free, and it should be read as compensation for risk rather than a pure bargain. If the project is delayed, you pay rent for longer while also servicing your loan, which quietly eats into the discount. If it stalls, the cost can be far larger. So the right way to think about the price gap is to ask whether the discount is enough to pay you for the specific risk of this builder and this project, not to assume that cheaper is automatically better.

What are the risks and benefits of each?

Ready to move offers certainty and speed, while under construction offers price and flexibility. With a finished flat you get immediate possession, you see exactly what you are buying rather than a sample, and you can earn rent or save rent straight away. The cost is the premium you pay and a narrower choice, since the best units in a completed project are often already gone.

Under construction, by contrast, gives you a lower entry price, staged payments tied to construction, and sometimes a wider choice of units and floors early in a launch. The cost is the risk: possession lies in the future, delays are common, and the finished quality is a promise rather than something you can inspect today. Neither option is safer in the abstract; the safer choice is the one that matches how much certainty you need and how much risk you can genuinely carry.

There is also a hidden cost of waiting that buyers forget to count. If you are renting while an under construction flat is built, the rent you pay over two or three years is money that never comes back, and it should be added to the under construction side of the ledger. A finished flat lets you stop paying rent immediately, which for many buyers narrows the real price gap far more than the sticker prices suggest. Counting the rent honestly is often what tips a close decision.

How do the two options compare at a glance?

The table below sets the two choices side by side on the points that most affect a Bengaluru buyer.

Read down the columns and the pattern is a genuine trade-off, not a clear winner. Ready to move buys certainty at a premium; under construction buys a discount in exchange for waiting and risk. The best choice is simply the one whose column matches what you actually need over the coming year.

Which should a Bengaluru buyer choose?

Choose ready to move if immediate possession, zero construction risk, or instant rental income matters more to you than upfront savings. If you are moving cities, your rent is high, or you simply cannot absorb the possibility of a delay, the certainty of a finished flat with a valid occupancy certificate is worth the premium. What you see is what you get, and that peace of mind has real value for many buyers.

Choose under construction if the lower price and staged payments suit you and you can genuinely tolerate a wait and some risk. This route rewards buyers who have time, a stable current housing situation, and the discipline to verify the builder's track record and RERA record before committing. The decision comes down to your timeline, your risk appetite, and what you need the property to do for you in the next twelve months, not to a blanket rule that one is always better.

Where buyers most often go wrong is by choosing on price alone in one direction, or on fear alone in the other. Someone who fixates only on the lower sticker of an under construction flat can end up carrying rent and stress through a long delay, while someone who pays any premium for a finished flat may overspend for certainty they did not really need. The better habit is to write down what actually matters to you, timing, budget, and tolerance for risk, and let those three answers, rather than the loudest sales pitch, pick the column.

What is the step by step decision for a buyer?

Work through this order before you choose:

1. Decide how soon you need to occupy or earn rent from the flat.
2. For a ready flat, confirm it has a valid occupancy certificate so no GST applies.
3. For an under construction flat, add the applicable GST to the base price.
4. Compare the all in cost of each after price, GST, and any rent you keep paying.
5. Assess the builder's delivery record and RERA status if buying under construction.
6. Judge whether the price discount fairly pays you for the delay and risk.
7. Match the final choice to your timeline and how much risk you can carry.

This decision connects to several others. For a ready flat, confirm the paperwork that makes it GST free using our guide to the occupancy and completion certificates, and whichever you choose, inspect it well with our flat possession and snagging checklist. If you are weighing a specific project such as Assetz Twin Lake City in Horamavu, compare its under construction price against finished flats nearby before you decide.

Frequently asked questions

Is there GST on a ready to move flat?

No. A ready to move flat with a valid occupancy certificate is exempt from GST, because it is treated as a completed asset rather than a service. GST applies only to under construction property, at 5 percent for standard homes and 1 percent for affordable ones. This exemption is one of the main financial advantages of buying a finished flat.

Is an under construction flat cheaper than a ready to move one?

Usually on the base price. Under construction flats typically cost 10 to 20 percent less than a comparable finished flat in the same micro market, and that discount often outweighs the GST charged on them. However, the saving compensates you for the wait and the delay risk, so it is not a pure bargain but a payment for taking on that risk.

What GST do I pay on an under construction flat?

The rate is 5 percent for a standard flat and 1 percent for an affordable one, where affordable means a carpet area up to 60 square metres in a metro and a value up to 45 lakh. Because GST is charged after a land deduction, the effective rate you pay is a little lower than the headline figure.

Which is safer, ready to move or under construction?

Neither is safer in the abstract. Ready to move removes construction and delay risk and gives immediate possession, but costs a premium. Under construction is cheaper and lets you pay in stages, but carries the risk of delay or quality issues. The safer choice for you depends on your timeline and how much risk you can genuinely carry over the next year.
