Under-construction vs ready-to-move apartments in Bangalore: the 2026 trade-off

The standard wisdom on under-construction versus ready-to-move apartments in Bangalore was that under-construction was 10 to 15 percent cheaper, gave the buyer choice of floor and view, and rewarded patience. The 2026 wisdom is messier. The 5 percent GST on under-construction units, the cumulative pre-EMI burden over a 3-year wait, the foregone rent, and the tightening of RERA enforcement against delayed projects have all narrowed the under-construction advantage. For most end-users at the 1 to 3 crore Bangalore price point, the question is no longer simply which is cheaper. The question is which is cheaper after the full math is run.

What is the actual price differential between under-construction and ready-to-move?

Under-construction units in Bangalore in 2026 typically price 10 to 20 percent below comparable ready-to-move units in the same project pocket. The differential is widest in early-launch phases and narrows as projects approach possession. Across the Sarjapur Road, Whitefield, and Hebbal corridors, the typical observed gap is 12 to 18 percent at the time of new launch.

The headline differential does not capture the full economics. Under-construction units carry 5 percent GST on non-affordable residential, which a ready-to-move unit with a valid occupancy certificate does not. For a 1 crore base price, that is an additional Rs 5 lakh in tax. For a 2.5 crore premium 3 BHK, GST quantum runs to Rs 12.5 lakh. The under-construction discount has to absorb this gap before a buyer is genuinely ahead.

How does GST work on under-construction Bangalore apartments?

Under-construction non-affordable residential apartments attract 5 percent GST without input tax credit, applied to the full sale value with a one-third deemed land deduction baked into the rate. Affordable housing, defined as carpet area of 60 sq m or less in metros with base price of Rs 45 lakh or less, attracts 1 percent GST without ITC. Ready-to-move apartments with a valid occupancy certificate before sale are excluded from GST entirely.

The 5 percent rate has applied since April 2019 following the 33rd GST Council meeting in February 2019. The earlier 12 percent with ITC structure was replaced because it was creating compliance friction and uneven pass-through to buyers. The current rate is simpler but does not allow the developer to claim ITC on inputs, which means the headline price already includes the cost impact of foregone ITC.

Buyers should verify that the developer's price sheet is not double-counting the one-third land deduction. The 1/3 deduction is baked into the headline 5 percent rate, not a separate refund. CAM above Rs 7,500 per month per unit attracts 18 percent GST on the full amount in metros, separately from the GST on the apartment purchase itself.

What is the difference between OC and CC for GST exemption?

OC is the occupancy certificate, issued by the local civic authority confirming the building is fit for occupancy and that all applicable approvals have been obtained. CC is the completion certificate, which the developer obtains internally and is a different document. For GST exemption on a ready-to-move sale, the CBIC's interpretation requires a valid OC, not just a CC. A unit being sold with only a completion certificate but without an occupancy certificate is not strictly GST-exempt under the standard treatment.

The distinction matters because some developers market units as ready-to-move based on construction completion without yet having received OC. Buyers should verify that the OC has actually been issued before relying on the GST-exempt status. The OC is verifiable through the local civic authority, which under the Greater Bengaluru Authority transition is the relevant city corporation.

For our broader take on what a buyer should verify before taking possession, our coverage of quality checks before taking possession still applies.

How does the pre-EMI burden during construction work?

Banks disburse home loans on under-construction projects in tranches linked to construction progress. Until the project is fully disbursed and possession is offered, the buyer pays interest only on the disbursed portion, called pre-EMI. Pre-EMI typically runs Rs 40,000 to Rs 1,20,000 per month depending on the loan size and the disbursement stage. Over a 3-year construction window, pre-EMI alone can total Rs 15 to 30 lakh.

If the buyer is not staying with family during construction, concurrent rent runs another Rs 35,000 to Rs 60,000 per month for a comparable rental in Sarjapur or Whitefield. Cumulative rent plus pre-EMI drag during a 3-year wait can total Rs 25 to 50 lakh, depending on loan size and rental cost. This is real money that does not appear in the under-construction price comparison.

Tax deductions under Section 24 for interest and Section 80C for principal start only post-possession for self-occupied units. Pre-construction interest can be claimed in five equal instalments after possession. The deferral of the tax shield further reduces the under-construction advantage during the construction wait.

What does RERA Section 18 actually protect against?

Under RERA Section 18, if a developer fails to deliver by the date committed in the agreement, the buyer can either withdraw and demand a refund with interest at SBI MCLR plus 2 percent, or continue and claim interest at the same rate for every month of delay. The protection is statutory and does not depend on negotiation with the developer. The buyer can file a complaint with K-RERA to enforce the refund or interest.

Section 18 has been used in multiple K-RERA orders through 2025 and 2026 against developers whose projects faced delays. The actual recovery time depends on the developer's financial capacity and the buyer's willingness to pursue the order through to its conclusion. For developers with strong balance sheets and active operations, Section 18 orders typically result in negotiated settlements before recovery proceedings begin. For developers under financial stress, the order is the start of a longer enforcement process.

K-RERA's January 2026 circular on quarterly progress report penalties has tightened the regulatory framework around delayed projects. For our coverage of how the QPR penalty regime works, see the dedicated piece.

When does an under-construction unit still win?

An under-construction unit still wins for buyers entering pre-launch or soft-launch phases of projects in pre-infrastructure micro-markets. Devanahalli pre-airport metro completion, Sarjapur pre-Phase 3A approval, or new Aerospace Park-adjacent areas where capital appreciation can outpace the 5 percent GST and pre-EMI carry. In these cases, the under-construction discount plus the appreciation during construction can exceed the GST and rent costs.

Under-construction units also offer floor, view, and configuration choice that ready-to-move inventory does not. Buyers with specific preferences for north-facing, top-floor, or particular block locations often have to accept compromises in the ready-to-move market. For premium 4 BHK and villament configurations, the customisation window during construction is sometimes the only way to secure the desired layout.

For investors with a 5-plus year horizon who are buying for capital appreciation rather than immediate use, under-construction at the right price point in the right location can outperform ready-to-move on a total return basis.

When does ready-to-move win?

Ready-to-move wins for end-users who want to move in immediately, for investors seeking immediate rental yield, for risk-averse buyers who do not want to absorb delivery risk, and for buyers with limited cash flow capacity to absorb dual rent plus pre-EMI during construction. Ready-to-move avoids the GST burden, eliminates the construction wait, and provides certainty about the actual unit being purchased rather than the brochure version.

For a buyer with a 1.5 crore Bangalore 3 BHK budget, the GST saving on a ready-to-move unit alone is Rs 7.5 lakh, before factoring in avoided pre-EMI and avoided foregone rent. The cumulative cash flow advantage often exceeds the headline price differential between the under-construction and ready-to-move options.

Risk-averse buyers benefit from being able to inspect the actual unit, the actual common areas, and the actual amenity infrastructure before committing. Construction-stage decisions are based on the developer's promises and the broader project track record. Possession-stage decisions are based on what is actually built.

How does the doubled registration fee change the math?

The Karnataka registration fee of 2 percent effective August 31, 2025 applies to both under-construction and ready-to-move purchases. For a 1.7 crore Bangalore apartment, the registration fee adds Rs 3.4 lakh to the transaction cost compared to the older 1 percent regime. This is on top of stamp duty at 5 percent, surcharge of 1 percent, and cess of 1 percent.

The total statutory cost stack now runs to roughly 9 percent of property value before factoring in lawyer fees, society transfer charges, and home loan processing costs. For under-construction units, the GST adds another 5 percent. For ready-to-move units, the GST is zero but the rest of the stack still applies. End-users should run the full math at the agreement stage rather than estimate from the headline price.

The proposed April 2026 guidance value hike will further raise the base on which both stamp duty and registration fee are calculated. Our coverage of the proposed guidance value revision walks through the implications.

What is the typical net economic comparison at 1.5 crore?

For a Bangalore 3 BHK at a 1.5 crore base price, an under-construction unit with a 12 percent discount lists at around Rs 1.32 crore, plus 5 percent GST of Rs 6.6 lakh, plus statutory costs of around Rs 11.9 lakh, for a total of roughly Rs 1.50 crore. A ready-to-move unit at the full Rs 1.5 crore base price with no GST and the same statutory costs of Rs 13.5 lakh totals around Rs 1.63 crore. The headline gap is around Rs 13 lakh in favour of under-construction.

The under-construction buyer then carries pre-EMI and concurrent rent during the construction wait. Pre-EMI at Rs 60,000 per month for 30 months totals Rs 18 lakh. Concurrent rent at Rs 45,000 per month for the same period totals Rs 13.5 lakh. The cumulative wait cost of Rs 31.5 lakh exceeds the headline Rs 13 lakh advantage by roughly Rs 18 lakh.

The math becomes more favourable for under-construction if the buyer is staying with family during construction or if the project's appreciation during construction exceeds the wait cost. It becomes less favourable if the project faces delays, which extends the wait cost without delivering offsetting appreciation.

What should an end-user buyer do over the next sixty days?

An end-user buyer over the next sixty days should run the full economic comparison for the specific projects under consideration, including base price, GST, statutory costs, expected pre-EMI, expected concurrent rent, and the project's K-RERA filings and committed possession date. The headline price is the wrong number to optimise on.

Buyers should also verify the OC status for ready-to-move options and the K-RERA registration plus QPR filings for under-construction options. For under-construction units, the developer's track record on previous delivery commitments is more useful than the marketing claims about the current project. Past delays predict future delays more reliably than glossy brochures predict timely delivery.
