The Smart Buyer's Master Checklist: Step-by-Step From Booking to Registry

Buying a home isn't one transaction — it's a sequence of roughly a dozen distinct steps, each with its own paperwork, its own verification points, and its own way of going wrong if you're not paying attention. Most buyers understand the two bookends clearly enough: pay some money at the start, get a registered title at the end. What happens in between — the allotment letter, the BBA, the loan disbursement schedule, the possession letter, the occupancy certificate, the mutation — is where confusion, and occasionally real financial risk, tends to concentrate.

This is the master checklist we'd want any buyer to have before they pay their first rupee: every stage from booking to registry, in order, with what to verify at each one.

Step 1: EOI and Booking Amount — What You're Actually Committing To

An Expression of Interest or booking amount is usually the first money a buyer pays, and it's worth understanding exactly what it does and doesn't commit you to before handing it over. This token payment typically reserves a specific unit and locks in a price, but the refundability terms attached to it vary significantly by developer and should be confirmed in writing before payment, not assumed. Ask specifically: under what conditions is this amount refundable, and is there a cooling-off period during which you can withdraw without penalty?

Before paying even this initial amount, confirm the project's RERA registration status directly on the state portal — this is the cheapest, fastest check available, and it should happen before any money changes hands, not after.

Step 2: The Allotment Letter — What to Verify Before You Accept It

The allotment letter is the first formal document confirming your specific unit, its price, and the payment schedule you'll follow, and it deserves careful reading rather than a quick signature. Cross-check the unit number, floor, carpet area, and total price against what was verbally discussed and against the project's RERA filing — discrepancies at this stage are far easier to correct than after a Builder-Buyer Agreement is signed.

This is also the point to request the complete cost sheet discussed in earlier due-diligence guides on this site — BSP plus PLC, EDC/IDC, IFMS, and other charges — so the price on your allotment letter reflects the real total, not just the headline base rate.

Step 3: The Builder-Buyer Agreement (BBA) — Your Last Free Checkpoint

The Builder-Buyer Agreement is the single most consequential document in this entire process, because it's what converts your position from a prospective buyer into a legally bound one. Every RERA verification step we've covered in detail elsewhere — registration status, extension history, Quarterly Progress Reports, escrow compliance, possession date alignment, sanctioned plan consistency — needs to happen before this agreement is signed, not after. Once signed, your recourse shifts to RERA's formal complaint process, which works, but starts from a considerably weaker position than simply not having signed a flawed agreement.

Read the possession date, penalty clauses for builder delay, and any clauses governing unilateral changes to the project carefully, and don't treat this as a formality to get through quickly on a sales office visit.

Step 4: Choosing a Payment Plan — Construction-Linked vs Down Payment

Choosing between a construction-linked payment plan and a down payment plan is a decision with real financial consequences that most buyers make without fully weighing. A construction-linked plan ties your payments to actual construction milestones, which reduces your exposure if the project stalls, since you're not paying for work that hasn't happened yet. A down payment plan, where a larger share is paid upfront in exchange for a discount, often offers better pricing but shifts more risk onto you if construction is delayed after you've already paid a large portion of the total price.

Neither is universally better — a construction-linked plan suits buyers prioritising risk reduction, while a down payment plan suits buyers confident in the specific developer's track record and prioritising the pricing benefit.

Step 5: Home Loan Disbursement — How It Actually Syncs With Construction

Home loan disbursement for an under-construction property doesn't arrive as a single lump sum — it's released in tranches tied to construction progress, matched against demand letters the developer sends as each stage is completed. Your bank will typically conduct its own verification of the project's RERA status, approvals, and construction progress before releasing each tranche, which is a useful second layer of scrutiny beyond your own checks, though it shouldn't be relied on as a substitute for doing your own.

Understand whether you're paying pre-EMI (interest only on the disbursed amount) or full EMI from the start, since this materially affects your monthly outflow during the construction period — a detail that's easy to overlook when focused on the headline interest rate.

Step 6: Monitoring Construction — Using QPRs and Site Visits

Monitoring construction progress after the BBA is signed isn't optional homework — it's the ongoing version of the due diligence you did before signing. Reviewing the project's Quarterly Progress Reports and comparing declared progress against what you observe on periodic site visits, as covered in more detail in our RERA red flags guide, remains relevant throughout the construction period, not just at the pre-booking stage. A widening gap between declared and observed progress is exactly the kind of signal worth raising with the developer immediately rather than waiting until the committed possession date has already passed.

Step 7: Possession — What “Possession Letter” Actually Means (and Doesn't)

A possession letter is the developer's formal communication that your unit is ready for handover, but it's worth being precise about what it does and doesn't confirm on its own. Some developers offer possession before a formal Occupancy Certificate has been issued — a practice that carries real risk, since occupying a unit without an OC can mean living in a technically unauthorised structure in the eyes of local authorities, with potential complications for utility connections and future resale.

Before accepting possession, confirm explicitly whether the Occupancy Certificate has actually been issued for your specific tower, not just promised as imminent. This single question protects you from a surprisingly common gap between “ready to move in” and “legally cleared to occupy.”

Step 8: Occupancy Certificate and Completion Certificate — Why the Difference Matters

The Occupancy Certificate and Completion Certificate are frequently confused, and the difference matters enough to spell out clearly. A Completion Certificate confirms the building's construction is finished according to the sanctioned plan. An Occupancy Certificate goes a step further, confirming the building is actually fit and legally cleared for people to live in — water, sanitation, fire safety, and other habitability requirements verified. Neither of these is the same as RERA registration, which is a separate compliance mechanism entirely.

A project can have a Completion Certificate without yet holding an Occupancy Certificate, and moving in during that gap is precisely the scenario described in the previous step. Ask for both documents specifically, by name, rather than accepting a general assurance that “the building is complete.”

Step 9: Final Inspection and Snagging — Before You Sign the Possession Acknowledgment

A final inspection, commonly called snagging, is your last practical opportunity to catch defects before formally accepting possession, and it deserves real time rather than a rushed ten-minute walkthrough. Check fittings, fixtures, paint quality, plumbing, electrical points, and common areas methodically, and document any defects in writing before signing the possession acknowledgment — once signed, your leverage to get issues fixed quickly diminishes considerably.

It's worth remembering that RERA mandates a five-year defect liability period after possession, during which a builder must repair structural defects free of cost within 30 days of notification — a protection worth invoking if something significant surfaces after you've moved in, even though a thorough snagging inspection upfront remains the better first line of defence.

Step 10: Registry (Sale Deed) — The Legal Transfer of Title

Registry, or registration of the sale deed, is the step that actually and legally transfers ownership to your name, and it must happen at the Sub-Registrar's office covering the property's jurisdiction, generally within four months of the document's execution. Both parties — or a properly executed Power of Attorney holder in the seller's or buyer's place — must be physically present along with two witnesses carrying valid identification, and the process involves biometric verification and document checks before both sides formally admit execution of the deed.

Stamp duty, calculated on the higher of the transaction value or the government-notified circle rate, is paid at this stage — in Uttar Pradesh, historically in the range of 7% plus a further 1% registration charge, though current rates should always be confirmed directly with the Sub-Registrar's office before the appointment. It's worth knowing that registration itself doesn't verify the seller's title — it creates a public record and establishes priority among competing claims — which is exactly why the legal and RERA verification steps earlier in this checklist matter so much; registration is a formality that assumes those checks were already done properly.

Step 11: Mutation — The Step Buyers Forget

Mutation is the step most buyers forget entirely, and it's genuinely separate from registration — completing one does not automatically complete the other. Mutation updates the property records held by the relevant local development authority or municipal body to reflect your name as the current owner, which is what ensures property tax bills and other official correspondence are correctly addressed to you rather than the previous owner. It typically requires submitting the registered sale deed along with a straightforward application, and processing generally takes a matter of weeks rather than months, for a modest fee.

Skipping mutation doesn't affect your legal ownership, which is established through registration, but it does create administrative friction down the line — from tax billing confusion to complications if you ever need to prove uninterrupted, correctly recorded ownership for a future sale or loan against the property.

A Consolidated Booking-to-Registry Checklist

●      Verify RERA registration status before paying any booking amount, and confirm the refundability terms of that payment in writing.

●      Cross-check the allotment letter's unit details and price against the RERA filing and request a complete, itemised cost sheet.

●      Complete every RERA due-diligence check — extensions, QPRs, escrow compliance, possession date alignment — before signing the BBA, not after.

●      Choose a payment plan deliberately, weighing construction-linked risk protection against down payment pricing benefits.

●      Understand your loan's disbursement schedule and whether you're paying pre-EMI or full EMI during construction.

●      Continue monitoring QPRs and conduct periodic site visits throughout the construction period.

●      Confirm the Occupancy Certificate has actually been issued before accepting possession, not just promised.

●      Request both the Completion Certificate and Occupancy Certificate by name, understanding they are not the same document.

●      Conduct a thorough snagging inspection and document defects in writing before signing the possession acknowledgment.

●      Book your Sub-Registrar appointment in advance, bring two witnesses with valid ID, and register within four months of document execution.

●      File for mutation separately after registration — it doesn't happen automatically.

Frequently Asked Questions About the Booking-to-Registry Process

What's the difference between an allotment letter and a Builder-Buyer Agreement?

An allotment letter is an initial confirmation of your unit, price, and payment schedule, while the Builder-Buyer Agreement is the comprehensive, legally binding contract that governs the full relationship between buyer and developer — the BBA is the more consequential document and deserves far more scrutiny.

Can I move into my apartment before the Occupancy Certificate is issued?

You generally shouldn't — occupying a unit without an issued Occupancy Certificate can mean living in a technically unauthorised structure, with potential complications for utility connections and future resale, even if the developer describes it as ready to move in.

Is registration the same as mutation?

No — registration legally transfers ownership and is done at the Sub-Registrar's office, while mutation is a separate, subsequent administrative step that updates local revenue and municipal records to reflect the new owner for tax billing purposes.

Does registering a sale deed prove the seller had valid title?

No — registration creates a public record and establishes priority among competing claims, but it does not itself verify that the seller's title was valid, which is why legal and RERA due diligence earlier in the process matters so much.

What should I check during a snagging inspection before accepting possession?

Check fittings, fixtures, paint quality, plumbing, electrical points, and common areas methodically, and document any defects in writing before signing the possession acknowledgment, since your leverage to get issues fixed quickly diminishes once you've accepted possession.

How long does mutation take after registration?

It generally takes a matter of weeks, though timelines vary by local authority, and it requires a separate application with the registered sale deed — it does not happen automatically just because registration is complete.

Conclusion: A Sequence Worth Following in Order

Every step in this checklist exists because skipping it, or doing it out of order, is exactly how buyers end up with disputes, delays, or documents that don't say what they thought they said. None of these steps require legal training to understand — they require knowing what to ask for and when to ask for it, which is precisely what this guide has laid out.
