New Launch vs Ready-to-Move 2026 — Which Apartment Should You Buy?

New launches list 10-20% cheaper than ready-to-move flats, but the headline discount rarely survives a full apples-to-apples comparison once GST, possession-delay risk, deferred tax deductions, and foregone rent are netted in. This guide breaks down every line of the math.

Updated May 2026 · 12 min read · Brickplot Editorial

The decision in one paragraph: The under-construction (new launch) versus ready-to-move (RTM) choice is the single largest fork in the apartment buyer journey. New launches are 10-20% cheaper on paper but carry real possession-delay risk — Indian builders historically deliver 18-26 months past RERA-declared dates on average, per state RERA portal filings. RTM properties cost more, attract zero GST (versus 5% on new-launch non-affordable and 1% on affordable under the CBIC notification), and remove timeline risk — but offer no further price discovery and cannot capture construction-period appreciation. The right answer depends on your buyer profile, not on which option is generically "better."

1. The price gap explained

New-launch apartments are typically priced 10-20% below ready-to-move (RTM) inventory in the same micromarket. The gap is widest at the foundation-and-plinth stage and narrows as the project progresses toward Occupancy Certificate. Builders price this way for two reasons. First, early-stage sales fund construction — every booking in the first 6-12 months reduces the developer s reliance on debt and shrinks finance costs, which they pass on partly as a discount. Second, the buyer is taking on construction risk and time-value-of-money cost, which the builder must compensate with a lower entry price to clear inventory. In top-tier Bangalore micromarkets like Whitefield, Sarjapur, and North Bangalore, the typical new-launch discount in 2026 ranges from 12% to 18% versus a comparable RTM unit. In tier-2 cities and weaker builder portfolios the discount can stretch to 25-30%, which is usually a signal of weak demand or execution risk rather than a bargain.

2. The GST trap on new launches

Under the CBIC notification effective 1 April 2019, GST on under-construction non-affordable apartments is 5% without input tax credit, and 1% on affordable housing (units below INR 45L with carpet area under 60 sqm in metros). A ready-to-move flat with a valid Occupancy Certificate attracts zero GST, because the sale of a completed property is not treated as a supply of construction service. This single factor changes the math materially. On a INR 1.2Cr apartment in Whitefield, the new-launch buyer adds INR 6L of GST on top of the agreement value; the RTM buyer pays nothing. Stamp duty applies to both at the same rate (5.6% in Karnataka in 2026 for properties above INR 45L). The 10-15% headline price discount on the new launch often shrinks to 5-7% after GST is layered in. Brickplot s decision framework treats GST as a sunk cost that must be netted against the apparent under-construction discount before any comparison is made.

3. Possession delay — the real-world numbers

Indian builders historically deliver well past their RERA-declared possession dates. Brickplot s analysis of RERA portals across Karnataka, Maharashtra, Haryana, Tamil Nadu, and Telangana shows an average possession delay of 18-26 months past the original committed date across all builders. The variance by builder tier is large. Top-tier listed builders (Prestige, Sobha, Godrej, Brigade, Mahindra Lifespaces, Oberoi) average 6-9 months of delay, with some projects delivering on time. Mid-tier regional builders average 14-20 months. Weaker builders, smaller proprietorships, and projects with NCLT or financial stress in the promoter group average 24-36 months, with a meaningful tail of projects that slip past 48 months or are abandoned entirely. RERA Section 18 entitles you to a refund with interest if the builder fails to deliver, but recovery is slow and depends on the builder s remaining asset base. The practical implication: a 12% headline discount on a new launch from a mid-tier builder is usually a fair price for the expected 18-20 month delay, not a bargain.

4. Pre-EMI vs full-EMI during construction

Two financing structures dominate the under-construction segment. Pre-EMI means the bank disburses the loan in tranches linked to construction milestones and you pay only the interest accrued on the disbursed portion each month. The monthly outgo is lower, but your principal does not reduce during construction, and the total interest paid over the loan life is higher. Full-EMI (sometimes called tranche-based EMI or full-pre-EMI from disbursement) means you start paying full EMI from the first disbursement, including principal repayment, even though only a fraction of the loan is disbursed. Monthly outgo is higher, but the loan amortises faster and total interest paid is lower. The third option — the subvention scheme — has the builder contract to pay your EMI during construction. The Reserve Bank of India and National Housing Bank have repeatedly flagged subvention as risky: the loan and CIBIL record remain in the buyer s name even though the builder is supposed to service the EMI. If the builder stops paying, the bank records it as your default. Brickplot recommends avoiding subvention schemes entirely unless the builder is a top-tier listed entity with audited financials.

5. Tax treatment — Section 24(b) and Section 80C

Section 24(b) of the Income Tax Act allows a deduction of up to INR 2L per year on home-loan interest for a self-occupied property. For an under-construction property, the interest paid during the pre-construction period cannot be claimed in the year of payment. Instead, the aggregate is divided into five equal installments and claimed starting from the financial year in which possession is taken, subject to the same INR 2L annual cap (combined with current-year interest). For a ready-to-move flat, the deduction is immediate and full from the financial year of possession. Section 80C provides a deduction of up to INR 1.5L per year on principal repayment, available on both RTM and under-construction loans, but only once you have started repaying principal (so a pre-EMI buyer gets no 80C benefit during the interest-only phase). For a INR 60L loan at 9% interest, the deferred deduction can shift the post-tax cost by INR 1-1.5L over the holding period in favour of RTM — a factor often missed in spreadsheet comparisons.

6. Capital appreciation timing

In theory, a new-launch buyer captures the construction-period price appreciation while the apartment is being built. If a micromarket is appreciating at 8% per year and construction takes three years, the buyer locks in todays price and benefits from cumulative appreciation of roughly 26% by handover. RTM buyers buy at the post-handover price and only earn future appreciation. In practice the picture is messier. NHB RESIDEX and Liases Foras data show that Indian residential prices are highly cyclical, with several micromarkets posting flat or negative real returns over 3-5 year windows. Possession delays of 18-24 months extend the holding period without any return, and a delayed project sometimes sees price erosion as buyer perception sours. Brickplot s position is that capital-appreciation arguments should never be used as the primary justification for a new-launch purchase. If the case for the project does not stand on builder track record, location fundamentals, and price-to-rent reasonableness, no expected appreciation can rescue it.

7. The rental income calendar

For investors, the rental opportunity cost of a new launch is large and often overlooked. A ready-to-move flat can be leased from the month of registration, generating rental yield typically of 2.5-3.5% in Bangalore, Pune, and Hyderabad and 1.8-2.5% in Mumbai. A new launch with a 3-year construction timeline plus 18 months of typical delay loses 4-4.5 years of rent. On a INR 1Cr apartment with 3% gross yield, that is INR 12L-14L of foregone gross rent (roughly INR 8L-10L net of maintenance, vacancy, and tax). For NRI investors, who typically buy for rental cashflow and capital protection rather than end-use, the under-construction proposition rarely makes sense unless the entry discount is at least 20% and the builder is in the top quartile of delivery record. End-users with a fixed move-in date have a different calculus — they need a place to live, and any new-launch delay forces them to extend a rental arrangement, which has its own cost.

8. Verifiable due diligence — what is easier in each

A ready-to-move property allows full physical due diligence before purchase. You can inspect the actual flat, measure carpet area against the agreement, test water pressure, see the parking ratio in practice, walk the common areas, talk to existing residents about builder service, verify society formation, confirm Occupancy Certificate, and check whether the STP and rainwater harvesting are commissioned. A new launch only allows paper diligence — RERA filings, sanctioned plan from BBMP OBPAS, Encumbrance Certificate, builder reputation, sample flat (which is rarely a reliable indicator of finish quality), and projected possession date. The information asymmetry strongly favours RTM, especially for first-time buyers and NRI buyers who cannot visit frequently. Brickplot s 11-axis score reflects this: axes like Liveability & Build Quality and Construction & Delivery Risk carry tighter confidence bands on RTM projects and wider bands on new launches, even when the headline score is similar.

9. A decision framework — four buyer profiles

Brickplot s editorial position is that the right answer depends entirely on buyer profile, not on which is generically "better." Profile (a): the end-user with a 2026 move-in need — RTM is almost always correct, because you cannot afford construction delay. The GST cost is offset by certainty of move-in and the ability to inspect before buying. Profile (b): the end-user with flexible move-in in 2027-2028 and willingness to absorb a 12-18 month delay — a new launch from a Tier-1 builder (Prestige, Sobha, Godrej, Brigade, Oberoi, Mahindra Lifespaces) can make sense, especially if you genuinely want pre-launch pricing in a micromarket that has structurally tight RTM supply. Profile (c): the NRI investor whose primary goal is rental income and capital preservation — RTM is strongly preferred, because rental from day one and full physical inspection both matter more than a 10-12% entry discount. Profile (d): the multi-property speculator or HNI investor using leverage for appreciation — new launch from a top-quartile builder is defensible, because the entry-price discount plus construction-period appreciation can amplify returns, and the investor is in a position to absorb a delayed project without personal disruption. Outside these four profiles, RTM should be the default.

Frequently Asked Questions

Is the 5% GST on under-construction property always cheaper than RTM with no GST?

No. On a non-affordable apartment priced at INR 1Cr, the new-launch buyer pays 5% GST without input tax credit, which is INR 5L on top of the agreement value. A ready-to-move (RTM) flat in the same micromarket may be listed 10-15% higher on paper, but attracts zero GST under the CBIC notification that applies once the Occupancy Certificate is issued. After you add stamp duty (which is calculated on agreement value in both cases), the headline price gap often shrinks to 5-7%. When you further account for 2-4 years of foregone rent, EMI carry, and possession-delay risk under RERA Section 18, the apparent new-launch discount frequently disappears for premium projects. For affordable housing (GST 1%), the math leans more favourably toward new launch, but the same delay-risk analysis still applies.

What happens to my pre-EMI payments if the builder defaults?

Pre-EMI is interest paid to the bank on the disbursed portion of your loan during construction. If the builder defaults or the project is abandoned, you remain liable to the bank for the principal already disbursed plus any unpaid interest, and you have already lost the pre-EMI payments as a sunk cost. Under RERA Section 18, you can seek a refund of the amounts paid to the builder with interest, but recovery is slow and capped at the builder s remaining assets. In subvention schemes where the builder contracts to pay your pre-EMI, NHB and RBI have flagged the practice as risky because the loan and EMI obligation remain in the buyer s name even when the builder stops paying. If the builder stops servicing the subvention, the bank treats it as your default and reports it to CIBIL. Bottom line: pre-EMI in a weak-builder project is among the most asymmetric downside trades in Indian real estate.

Can I claim Section 24(b) interest deduction on an under-construction property?

Yes, but the deduction is deferred. Under Section 24(b) of the Income Tax Act, interest paid during the pre-construction period cannot be claimed in the year of payment. Instead, the aggregate pre-construction interest is divided into five equal installments and claimed starting from the financial year in which construction is completed and possession is taken. The annual cap on self-occupied property interest deduction is INR 2L per year (combined with current-year interest). For a ready-to-move flat, the deduction is immediate from the financial year of possession, with no five-year split. This is one of the most underappreciated tax differences in the new-launch vs RTM decision, and on premium loans (above INR 50L) it can shift the effective post-tax cost by 1-1.5 percentage points in favour of RTM.

How does Brickplot s verdict differ between new-launch and RTM projects?

Brickplot s 11-axis scoring formula applies to both, but the inputs and confidence change materially. For RTM projects, axes like Liveability & Build Quality, Construction & Delivery Risk, and Governance & Approvals Depth can be scored from observable evidence (OC, society formation, on-site inspection, parking ratio measured, STP commissioned). For new launches, those same axes rely on paper diligence — RERA filings, builder reputation, sample flat, sanctioned plan — and the score includes a wider confidence band. Hard caps tied to delivery (no OC after 6 months post-handover) only fire on RTM. New launches are more vulnerable to caps tied to disclosure (no valid RERA registration, zero banks in APF list post-12-months, promoter NCLT/IBC). A Buy Now verdict on a new launch therefore implies a higher trust burden on the builder s execution record than the same verdict on an RTM project.
