Comparison
Ready-to-Move vs Under Construction: Which is Better?
Ready-to-move gives certainty. Under-construction gives price advantage. Here's how to choose in 2026.
Price
Under-construction is 10–20% cheaper than ready-to-move in the same micro-market. Discount narrows in the last 6 months before OC.
Risk
Under-construction: delivery delay, spec change, developer default. Ready-to-move: none of the above.
GST
Under-construction attracts 5% GST (1% for affordable). Ready-to-move (with OC) attracts zero GST — a big saving.
Home loan
Pre-EMI on under-construction can go on for 3–4 years and is not fully tax-deductible until possession.
Investment returns
If the developer is A-grade and the corridor is under-priced, under-construction can deliver 15–20% higher IRR. In an uncertain market, ready-to-move wins on risk-adjusted return.
The true cost comparison
Under-construction inventory prices 15–25% below completed stock but adds 5% GST, three to five years of foregone rent, and pre-EMI interest if you are borrowing. Ready inventory carries no GST, starts earning immediately, and lets you inspect the actual product. Run the numbers over your holding period: on a five-year view, the under-construction discount usually wins if delivery is on time; on a two-year view, ready almost always wins.
Risk allocation
Under-construction risk is concentrated in delivery: schedule slippage, specification downgrades, layout changes and, rarely, promoter insolvency. Ready-inventory risk is concentrated in the asset itself: a building that has already shown its construction quality, a society that may be poorly maintained, and older-generation amenities. HRERA escrow and penalty provisions have narrowed the gap, but they compensate for delay rather than prevent it.
Inspection checklist for ready homes
Visit at three different times of day. Check water pressure on the top floor, basement seepage after rain, lift maintenance logs, DG backup coverage per unit, actual power-cut behaviour, parking allotment versus car count, RWA financial statements and sinking-fund balance, pending litigation, and whether the occupation certificate covers your specific tower. Ask two residents about their biggest complaint — the answer is usually the thing brochures never mention.
A decision rule
Buy ready if you need to move within a year, are risk-averse, are an NRI who cannot supervise construction, or want immediate rental income. Buy under-construction if you have a five-year-plus horizon, are buying from a developer with a clean delivery record in that corridor, can absorb a 6–12 month delay, and want to capture the launch-to-possession price gap.
How escrow accounts actually protect an under-construction buyer
Under RERA, 70% of the funds collected from buyers for a project must be deposited in a separate escrow account and can only be withdrawn in proportion to construction progress, certified by an engineer, architect and chartered accountant. This mechanism is designed to prevent the historical problem of developers diverting one project's collections to fund land acquisition or construction on another project. However, escrow protects construction funding, not your specific delivery date guarantee — a developer can be escrow-compliant and still delay possession due to approval bottlenecks, contractor disputes or force majeure claims. Ask the developer or their RERA-registered agent for the quarterly progress report filed with HRERA, which is public information and shows actual disbursement versus construction milestone, a far more reliable signal than the sales team's verbal assurance.
Specification lock-in: what you can and cannot change after buying under-construction
Buying under-construction lets you sometimes select flooring, fittings or minor layout tweaks if you book early enough in the construction cycle, a flexibility completely unavailable in ready inventory where the unit is delivered as-is. However, most builder-buyer agreements explicitly reserve the right for the developer to substitute 'equivalent or superior' materials and fittings without buyer consent, which has occasionally been used to downgrade specifications quietly — always request the detailed specification annexure with brand names, not generic category descriptions, attached to the agreement. Layout changes beyond minor internal walls typically require regulatory plan amendments and are rarely accommodated once the structure crosses a certain construction stage, so if a custom layout matters to you, that window closes early and should be negotiated at booking, not after.
Rental income timing and the true cost of a vacant investment
A ready-to-move purchase can theoretically start earning rent within 30–60 days of possession and registry, while an under-construction purchase earns zero rental income for the entire construction period, which for a launch-stage project in Gurgaon typically runs three to five years. This foregone rent is a genuine opportunity cost that many investors omit from their comparison — on a ₹1.5 Cr property yielding even a conservative 2.5%, that is roughly ₹3.75 L a year, or ₹15–18 L across a four-year construction period, which should be netted against the under-construction discount when comparing true returns. Investors who need income during the holding period should weight this heavily; those investing purely for capital appreciation with no income need can reasonably discount this factor.
Loan structuring differences that affect monthly cash flow
For under-construction property, most buyers choose pre-EMI, paying only interest on the disbursed amount until possession, which keeps monthly outflow lower during construction but means the full principal repayment clock does not start until years later, effectively extending your total interest cost over the loan's life compared to full EMI from day one. For ready-to-move property, the full EMI (principal plus interest) starts immediately since the entire loan amount is disbursed at once, giving a clear, stable, and typically shorter path to full repayment. Buyers who can afford full EMI on an under-construction purchase from day one — rather than opting for pre-EMI by default — build equity faster and pay meaningfully less total interest over the loan tenure, an option worth discussing explicitly with your lender rather than accepting the default structure.
Negotiating power differs sharply between the two categories
Under-construction pricing is more negotiable at the project level because developers manage inventory release in phases and have flexibility on payment plans, floor-rise charges and PLC waivers to move slow-selling towers or floors. Ready-to-move negotiation happens unit-by-unit in the resale market, where leverage depends on the specific seller's urgency, pending home-loan transfer formalities, and how long the unit has been listed — cash-ready buyers with no chain of dependent transactions consistently negotiate 4–8% below asking in Gurgaon's resale market. Buyers should recognise that 'discount' in under-construction typically comes through waived charges rather than a lower base rate, while resale discount is a genuine reduction in the transacted price.
Reading a builder's delivery track record before choosing under-construction
Do not rely on a developer's brand reputation alone — pull the HRERA project page for their last three completed projects and compare the originally committed possession date against the actual OC-issuance date recorded on the portal. A developer with a consistent one-to-two-year delay pattern across multiple projects is a structural risk, not a one-off; a developer who has delivered within six months of committed dates on recent projects is a materially safer under-construction bet regardless of brand size. Visit at least one delivered project from the same developer in a similar price band, ideally in the same city, and speak to residents about the gap between what was promised at booking and what was actually delivered — this single step surfaces more real information than any brochure comparison.
A hybrid strategy some Gurgaon buyers use
Some end-users manage the risk-versus-price tradeoff by renting a ready-to-move home in their target sector while their under-construction purchase completes, effectively getting immediate livability in the same micro-market at a fraction of the ownership cost, while their capital compounds in the discounted under-construction asset. This works best when the rental yield in the sector is low relative to expected capital appreciation, making renting cheaper than the opportunity cost of buying ready immediately. It requires financial discipline to manage two housing-related cash outflows (rent plus pre-EMI) simultaneously and is best suited to buyers with stable, well-margined incomes rather than those already stretching their budget.
Capital gains tax treatment differs meaningfully between the two categories
For a ready-to-move property, the holding period for long-term capital gains starts from the registration date, giving a clear and immediate reference point; for an under-construction property, tax authorities and case law have generally held that the holding period starts from the date of allotment or the builder-buyer agreement rather than the eventual possession or registration date, provided the buyer can demonstrate the allotment created enforceable rights — a distinction that can materially affect whether a sale soon after possession qualifies for long-term capital gains treatment. Buyers planning an exit within a few years of possession should retain the original allotment letter and payment schedule as evidence of the earlier holding-period start, and consult a chartered accountant on current case law before assuming either treatment automatically.
Depreciation and wear consideration when comparing 'ready' inventory of different ages
Not all ready-to-move inventory is equivalent — a newly completed project with a fresh occupation certificate behaves very differently from a 10–15 year old resale society in terms of near-term capital expenditure the buyer should expect, including elevator overhauls, façade repainting, waterproofing renewal and electrical rewiring that ageing societies typically fund through special maintenance levies beyond the regular monthly charge. When comparing a brand-new ready project against an older resale option at a similar price point, buyers should request the RWA's five-year maintenance and capital-expenditure history, since an older society with a poorly funded sinking fund can surprise a new owner with a large one-time levy within the first year or two of purchase.
GST input considerations for investors buying under-construction for eventual resale
An individual investor buying an under-construction residential unit for resale (rather than end-use) pays 5% GST without input tax credit under the current residential GST regime, meaning this cost cannot be offset against any GST liability and is effectively a sunk cost embedded in the acquisition price, unlike commercial property purchases where GST-registered buyers can often claim input credit. This makes the GST cost a genuine, non-recoverable drag on under-construction residential investment returns that should be modelled explicitly against the acquisition-discount thesis, rather than treated as a pass-through cost, since no offsetting credit mechanism exists for residential purchases regardless of the buyer's intent to resell.
Insurance and warranty coverage differences at handover
Ready-to-move purchases in an established society typically inherit whatever structural warranty period remains from the original construction (structural defect liability under RERA runs five years from possession), meaning a resale buyer purchasing in year three of that window still has two years of builder liability for structural defects, a fact many resale buyers overlook and fail to invoke when defects surface. A fresh under-construction purchase gives the buyer the full five-year structural defect liability window from their own possession date, a meaningfully longer protection runway than buying resale inventory that is already several years into its warranty period — a factor worth weighing for buyers who prioritise long-tail structural protection over immediate occupancy.
Exit liquidity comparison specifically for investors, not end-users
For an investor modelling exit rather than personal use, ready-to-move inventory in an established, loan-approved society offers the fastest and most predictable exit because buyers can inspect the actual unit, get immediate bank approval, and move in without waiting — typically clearing within 60–90 days at a fair market price in liquid Gurgaon micro-markets. Under-construction exit before possession, through an assignment or nomination transfer, is a thinner market with fewer buyers willing to take on the remaining construction and payment risk, and some builder-buyer agreements restrict or charge a transfer fee for pre-possession assignment, so investors planning a pre-possession exit should confirm the specific project's assignment policy and fee structure before booking, not after deciding to sell.
Frequently asked
- Is GST payable on ready-to-move flats?
- No. GST applies only to under-construction property at 5% without input tax credit (1% for affordable housing). A unit with an occupation certificate attracts no GST.
- How much cheaper is under-construction property?
- Typically 15–25% below comparable ready inventory at launch, with the gap narrowing as construction progresses.
- What happens if an under-construction project is delayed?
- Under RERA you can claim monthly interest at SBI MCLR plus 2% for the delay period, or withdraw and claim a full refund with interest through the HRERA authority.
- Does RERA escrow guarantee my under-construction project will not be delayed?
- No, escrow protects construction funding from being diverted to other projects, but it does not guarantee your specific possession date, since delays can still occur due to approvals, contractor issues or other factors.
- Should I choose full EMI or pre-EMI for an under-construction property?
- Pre-EMI keeps monthly outflow lower during construction but increases total interest paid over the loan's life, since principal repayment starts later; full EMI from day one builds equity faster and costs less overall if you can afford the higher initial outflow.
- How much rental income do I lose by buying under-construction instead of ready-to-move?
- On a typical three to five year construction period, foregone rent can add up to 15-20% of the property's value at a conservative yield, an opportunity cost that should be weighed against the under-construction discount.
- Can I customise the interiors of an under-construction flat?
- Some customisation like flooring or fittings may be possible if booked early in construction, but layout changes are rarely accommodated once construction crosses a certain stage, and developers usually reserve the right to substitute materials unless specific brands are named in the agreement.
- How do I check a builder's actual delivery track record before buying under-construction?
- Compare the committed possession date against the actual occupation-certificate date on the builder's last three projects using the public HRERA project pages, rather than relying on brand reputation alone.
- When does the capital gains holding period start for an under-construction property?
- Generally from the date of allotment or the builder-buyer agreement rather than possession or registration, provided the buyer can demonstrate the allotment created enforceable rights — retain the original allotment letter as evidence and confirm current treatment with a chartered accountant.
- Can I claim GST input credit on an under-construction flat I plan to resell?
- No, individual buyers of residential property pay 5% GST without input tax credit regardless of resale intent, making it a non-recoverable cost that should be modelled explicitly against any acquisition discount.
- Does a resale ready-to-move flat still have builder warranty protection?
- Yes, if it falls within the five-year RERA structural defect liability period measured from the original possession date, though a resale buyer inherits whatever portion of that window remains rather than getting a fresh five years.
