Apartment Buying Checklist Before Booking

The token amount you pay to book a flat is small compared to the total price, which is exactly why it is paid so quickly and reviewed so little. Once it is paid, you are emotionally and often contractually committed. This checklist is meant to be worked through before that payment, not after, since almost everything on it is far easier to verify or negotiate while you still hold the leverage of not having paid anything.

It is organised into four groups — documents, finances, the physical site, and legal terms — because each requires a slightly different approach and, in some cases, a different person's help. Treat it as a working list you can hand to a lawyer or a trusted advisor rather than something to rush through alone in a single sales office visit. This is especially relevant for under-construction purchases, where the token amount is paid well before construction is complete and before most physical details can be verified in person — which makes the paperwork checks even more important than the site visit itself.

Documents to verify before booking

These establish whether the project has the legal standing to be sold to you in the first place, and are worth checking independently rather than accepting the sales team's summary.

• RERA registration certificate for the specific project, checked against the state RERA portal
• Title documents or property card confirming clear land ownership
• Commencement certificate from the local planning authority for the current phase of construction
• Approved layout and building plan, matched against what is being marketed
• Draft allotment letter and agreement for sale, reviewed before you sign anything

If any of these documents are unavailable on request, or only offered in part, treat that as a signal to slow down rather than a formality to overlook. A hesitant or evasive response to a straightforward document request is one of the more reliable early warning signs in the entire booking process.

Financial checklist

This is where hidden costs and payment structures that do not suit your cash flow tend to surface, if you look for them before booking rather than after.

• A written, itemised total cost breakup — base price, GST if applicable, parking, club and other charges — not just a verbal quote
• Payment schedule tied to construction milestones for under-construction property, rather than a front-loaded schedule
• Confirmation of GST applicability, which depends on whether the Occupancy Certificate has already been issued
• Home loan pre-approval or in-principle sanction, so the booking is backed by confirmed financing
• The token amount refund policy in writing, in case you need to withdraw before the formal agreement is signed

Pay particular attention to whether the payment schedule is genuinely construction-linked or simply a fixed calendar unrelated to actual progress on site. A construction-linked schedule protects you if the project falls behind, since you are not obligated to pay the next instalment until the corresponding stage is actually reached — a calendar-based schedule offers no such protection.

Physical checklist during the site visit

Marketing renderings and sample flats are designed to present a project at its best. A structured physical checklist helps you see past that to what you will actually be living in.

• Measure or verify the carpet area against the figure quoted in the agreement, not the brochure's super built-up number
• Compare the sample flat's finishing to the actual unit under construction, where possible
• Check the unit's orientation, natural light, and view, ideally at more than one time of day
• Confirm the exact parking allotment — covered or open, and its location relative to the tower
• Ask for the current construction status of amenities shown in renderings but not yet built

Bring a measuring tape if you can, and do not hesitate to ask the sales team for the RERA-registered carpet area figure again in writing while you are on site. A builder confident in their own disclosures will not be reluctant to provide the same figure twice.

Legal checklist

This is the group most buyers are least equipped to review alone, and the one where a modest legal fee upfront can prevent a far more expensive dispute later.

• Have the draft agreement for sale reviewed by a lawyer, particularly the possession and penalty clauses
• Confirm what compensation applies if the declared possession date is missed
• Check indemnity clauses and what they hold the builder responsible for after possession
• Understand the timeline and process for society formation and maintenance handover

A one-time legal review fee, typically a small fraction of the property's value, is inexpensive relative to the cost of discovering a problematic clause only after a dispute has already arisen and the agreement is already signed.

What happens if you skip these checks

Buyers who skip this checklist most commonly run into two problems later: a possession delay with no clear compensation, because the agreement's penalty clause was never reviewed before signing, or a mismatch between the carpet area paid for and the area actually delivered, discovered only at possession when a re-measurement is far harder to dispute. Both problems are avoidable with the same few hours of verification described above, done before rather than after booking.

Red flags at the booking stage

• Pressure to pay the token amount the same day, backed by a discount that expires immediately
• Reluctance to share the draft agreement for sale before payment is made
• Verbal assurances about specifications or amenities that are not reflected anywhere in writing
• Inability or unwillingness to produce the RERA registration certificate on request

A short pre-booking checklist

As a final pass before you pay the token amount, work through this in order.

1. Confirm RERA registration is active and matches the project being sold to you
2. Get the full cost breakup in writing, not verbally
3. Have your home loan pre-approval in hand
4. Read the draft agreement for sale, or have a lawyer read it, before signing
5. Confirm the token refund policy explicitly

The bottom line

None of these checks take more than a few days to complete, and every one of them is harder to act on after you have paid. Slowing down at this specific stage is the single highest-leverage thing a buyer can do in the entire process. Treat this as a starting point for your specific project rather than an exhaustive list — larger integrated townships or phased developments may warrant additional checks around infrastructure commitments that are specific to that project.
