How to Verify a Builder Before Booking: A Buyer's Due-Diligence Checklist

The builder you buy from matters as much as the flat itself. A good developer delivers on time, builds to the quality promised, and hands over a project with clean paperwork; a weak one leaves buyers waiting years, fighting over defects, or chasing approvals that were never in place. Verifying a builder before you book is the single most effective way to avoid the most painful problems in real estate — delayed possession, quality disputes, and legal tangles. This guide sets out what to check, where to check it, and the warning signs that should make you pause.

None of this requires insider access; most of it is public or available on request, and RERA has made a great deal of it searchable. Because processes and portals vary by state and evolve over time, use this as a checklist of what to verify rather than a fixed procedure, and confirm the current sources for your city. The goal is simple: replace the developer's marketing with facts before any money changes hands.

Start with RERA registration

For most new projects, the first and most important check is the project's registration under the Real Estate (Regulation and Development) Act. A registered project has disclosed key details to the regulator, and its registration page is the anchor for the rest of your due diligence.

What the RERA page tells you

The registration record typically discloses the promoter's details, the sanctioned plan and approvals, the declared timeline for completion, the land title status, and any complaints or orders against the project. Confirm the registration number the builder quotes actually resolves to the project you are buying, and read what it says rather than taking the number as a rubber stamp.

Check the promoter's history

Look at the promoter's other registered projects and how those have progressed. A developer with a track record of registering and completing projects is a very different proposition from one with a thin or troubled history.

Verify the track record of delivery

Marketing brochures show renderings; delivery shows reality. Look at the builder's completed projects, not just the ones under construction. Visit a handover-stage or occupied project if you can, and talk to residents about whether the developer delivered on time, honoured commitments, and dealt fairly with defects and the handover of common areas. A pattern of long delays or unresolved complaints across projects is one of the strongest signals to walk away.

Approvals, title and the land itself

A project is only as sound as the land and approvals beneath it. Confirm that the developer has clear title or clear development rights to the land, and that the necessary approvals — the sanctioned building plan and the permissions required at the project's stage — are in place. Missing or pending approvals are a frequent cause of stalled projects, because construction that races ahead of its permissions can be halted. Where the amounts are significant, have the title and approvals reviewed by a property lawyer rather than relying on assurances.

Financial health and funding

A builder's ability to finish depends on their finances. A developer who is over-leveraged, juggling too many simultaneous launches, or relying entirely on incoming buyer money to fund construction carries more risk of a stall. You will not see audited accounts as a buyer, but you can look for indirect signals: the pace of construction on their current sites, whether they have institutional funding, and whether reputable lenders have approved the project for home loans. A project that leading banks are comfortable financing has passed a layer of independent scrutiny.

Read the agreement, not just the brochure

The builder's commitments only count if they are in the agreement. Read the allotment letter and the agreement for sale carefully, paying attention to the possession date, the specification of what is being delivered, the payment schedule, and the clauses on delay, cancellation and compensation. Be wary of one-sided terms that penalise you heavily for delay while giving the developer wide latitude. If the agreement contradicts what the sales team promised, the written document is what governs.

Warning signs to take seriously

Some signals should make you slow down: a project selling aggressively before basic approvals are visible, a builder reluctant to share the RERA number or paperwork, pressure to pay a large amount quickly against vague terms, a history of delayed projects, or prices that look too good relative to the area. None of these is automatically disqualifying, but each is a reason to dig deeper and to insist on documentation before committing.

Talk to the right people

Beyond the paperwork, real information comes from people with no stake in your sale. Existing residents will tell you about delays and defect handling. A property lawyer will tell you whether the title and approvals hold up. A home-loan officer's willingness to fund the specific project is a useful independent check. Weigh these against the sales pitch, and give more weight to the sources that do not earn a commission when you sign.

Reduce the risk before you ever book

The cleanest protection is to shortlist only projects where the developer's registration, approvals and title have already been checked. Doing the verification up front means the situations that trap buyers — an unregistered project, missing approvals, a developer with a poor delivery record — are filtered out before you fall in love with a flat. A little diligence at the shortlist stage saves years of difficulty after booking.
