Questions to Ask a Builder Before Buying a Flat

Arjun sat across from a builder's sales executive in a well-lit office, a glossy brochure open between them, a scale model of the tower behind glass to his left. The pitch was smooth: "This is our fastest-selling phase, sir, only a few units left at this price." He nodded along, asked about the swimming pool timings, and almost signed an application form before it occurred to him that he hadn't asked a single question about the project's RERA registration, the actual all-in cost, or what happens if possession is delayed. He left, came back a week later with a written list of questions, and walked out that second time with a project RERA number, a written cost breakup, and a payment schedule — none of which had been volunteered the first time.

This is the situation most first-time buyers find themselves in: facing a confident, well-rehearsed sales pitch with no comparable script of their own. You don't need a law degree to ask good questions. You need a structured set of fact-based questions that surface approvals, true costs, and timelines — and the discipline to get the answers in writing rather than accepting them verbally.

Why Ask for Facts and Documents — RERA Basics

The Real Estate (Regulation and Development) Act, RERA, requires most residential projects above a threshold size to register with the state's RERA authority before advertising or selling. Registration brings with it a declared completion date, a defined carpet-area disclosure standard, and a public project page where much of what a sales team tells you should also appear in writing.

This matters for a simple reason: a question answered verbally in a sales office carries no weight later, but a fact filed with a state regulator, or printed on a receipt, does. Every question in this article is designed to produce something you can independently verify — a RERA number you can look up, a document you can photograph, or a written figure you can compare against what's charged later — rather than a reassurance you simply have to trust.

According to ANAROCK's Consumer Sentiment Survey H1 2025 (via MediaBrief, 08 Sep 2025), which covered around 8,250 respondents across 14 cities, developer credibility remains a persistent theme in how Indian buyers evaluate a purchase, with a large majority of respondents identifying as end-users rather than investors — people buying a home to live in, for whom getting the facts right the first time matters even more. Meanwhile IBEF's Real Estate Industry in India report (Feb 2026) notes that FY25 delivery volumes rose sharply (406,889 units, up 33% year-on-year) — a sector in a fast-delivery phase where asking precise, dated questions about your specific project's status is more useful than ever.

Step-by-Step Question Framework

Organize your questions into five categories and work through them in order, ideally with a notebook or your phone open to record answers as you go.

1. Legal and RERA identity. Start here, before anything about amenities or price. Ask for the project's RERA registration number and confirm it against the state RERA portal yourself — never take a printed number at face value without checking it.

2. Approvals and permissions. Ask which approvals are already in place versus pending — commencement certificate, sanctioned building plan, environmental clearance (for larger projects), and, for ready units, the completion or occupancy certificate.

3. True, all-in cost. Ask for a complete cost breakup in writing: base price, floor-rise charge, preferential location charge (PLC), parking, clubhouse/amenity charge, corpus/maintenance deposit, GST (applicable on under-construction properties), stamp duty, and registration charges.

4. Timeline and delay terms. Ask for the declared possession date as filed with RERA, and specifically what the delay-compensation clause says if that date is missed — this is often buried in the agreement rather than mentioned during a sales pitch.

5. Handover and post-possession terms. Ask what exactly gets handed over at possession (fittings, finishes, parking allocation) and what the maintenance arrangement looks like in the initial period.

Throughout, log what you're told using DrawMagic's AI Home-Buying Companion — a private, voice-first way to capture the builder's answers right after a meeting, so your decision journey has a running record of what was promised and by when, rather than relying on memory or a scattered notebook.

Question Bank: Grouped by Category

Geographic and Demographic Specifics: State RERA Portals and Approval Documents

RERA is implemented state-by-state, so the portal you check depends on where the project is located — for example, MahaRERA for Maharashtra, Karnataka RERA (K-RERA) for Karnataka, TS-RERA for Telangana, and equivalent bodies in other states. Ask the builder which state portal to check and get the exact registration number in writing so you can search it yourself rather than relying on a screenshot they provide.

Approval documents to specifically ask to see (not just hear about):

• Commencement certificate — confirms the local authority has permitted construction to begin.
• Sanctioned building plan — the officially approved layout, useful to compare against what's being marketed.
• Environmental clearance — required for larger projects above defined thresholds; ask if it applies to this project's size.
• Completion certificate / occupancy certificate — for a ready-to-move unit, this should exist before possession; its absence is a fact worth noting and following up on independently, not something to interpret as a verdict on the builder.

The consistent theme: ask for the document or the number, and treat any answer as a lead to verify on the relevant public portal, not as a fact in itself. This keeps the process squarely in "confirm independently" territory rather than asking you to take anyone's word for it — DrawMagic's own buyer intelligence resources are built around exactly this kind of official-records transparency and locality context, to help you cross-check what you're told against public sources.

Real-World Mini Scenario: A Mumbai Buyer Asks for the MahaRERA Number

A buyer evaluating a project in the Mumbai Metropolitan Region is told during the sales pitch that "possession is guaranteed within 36 months and the project is fully approved." Rather than accepting this, the buyer asks for the MahaRERA registration number and the declared completion date on the portal, plus a written payment plan showing whether it's construction-linked or time-linked.

The sales team provides the MahaRERA number; checking the MahaRERA portal directly shows a declared completion date that is about four months later than what was verbally stated, and the project page lists specific approvals already granted. Rather than treating the discrepancy as alarming, the buyer simply notes the RERA-filed date as the reliable figure to plan around, asks for the payment plan structure in writing, and moves forward with a realistic timeline in mind — a far better outcome than discovering the gap only after paying a booking amount and calculating EMIs against a marketing-team estimate.

How to Verify the Answers Afterwards

• Cross-check the RERA number on the relevant state RERA portal yourself — search by project name or registration number and compare the declared completion date, promoter details, and sanctioned plan against what you were told.
• Compare the written cost breakup against the final demand letter or agreement before signing, to confirm nothing new has been added.
• Photograph or request copies of any approval documents shown to you, so you have your own record independent of what the sales office retains.
• Note discrepancies calmly and ask for clarification rather than assuming either dishonesty or a mistake — dates and figures sometimes change between when a project first registers and when a specific phase is marketed.
• For anything you can't verify yourself, consult a licensed legal or property professional before signing an agreement — this article gives you the questions to ask, not a substitute for professional legal review of the agreement itself.

Pro Tips

• Bring a written list of questions and check them off as you go — a sales conversation moves quickly, and a physical list keeps you from being steered away from unanswered items.
• Ask early in the conversation, not after you've emotionally committed — questions about approvals and delay clauses feel harder to ask once you've mentally moved into the unit.
• Request everything "in writing" as a specific phrase — it signals you expect documentation, not just reassurance, and most sales teams respond accordingly.
• Ask the same core questions of more than one project — comparing answers across two or three options sharpens your sense of what a normal, complete answer looks like.
• Separate "what's approved today" from "what's expected" — a builder describing a pending environmental clearance as a formality is giving you a projection, not a fact; note the distinction.

Common Mistakes to Avoid

• Accepting verbal-only claims about approvals, timelines, or inclusions without asking for the underlying document or number.
• Ignoring the all-in cost and anchoring only on the headline base price quoted in marketing material.
• Not checking the RERA portal independently, even after receiving a registration number — the number itself needs to be verified, not just collected.
• Skipping the delay-compensation clause because the conversation feels too far ahead of a "worst case" scenario — this clause matters precisely because delays are not rare in the sector.
• Letting "limited units left" urgency skip the question phase entirely — a legitimate opportunity survives a buyer asking a complete set of fact-based questions.

Integration with DrawMagic

Once you've gathered the builder's answers, DrawMagic's AI Home-Buying Companion gives you a private, persistent place to log what was promised — RERA number, approvals status, cost breakup, and timeline — so it's part of your evolving requirements brief rather than scattered across notebooks and screenshots. Cross-reference what you were told with DrawMagic's buyer intelligence resources for locality context and official-records transparency before you commit to anything financially.

Before agreeing to any cost structure, run the true all-in price through the EMI calculator — a base price quoted verbally often understates the real monthly commitment once floor-rise, PLC, and GST are added in. When you're ready to keep all of this organized in one account across multiple builder conversations, sign up for free and carry your question log and shortlist forward as you compare projects.

Key Takeaways

• Start every builder conversation with the RERA registration number, and verify it yourself on the state RERA portal — never take the number at face value.
• Ask for approvals (commencement certificate, sanctioned plan, environmental clearance, completion/occupancy certificate) as named documents, not general assurances.
• Request a written, itemized all-in cost breakup covering base price, PLC, floor rise, parking, corpus, GST, stamp duty, and registration.
• Ask specifically what the delay-compensation clause says if the RERA-declared possession date is missed.
• Get handover specifications (fittings, finishes, parking allocation) in writing before relying on marketing-language descriptions.
• ANAROCK's H1 2025 survey highlights developer credibility as a persistent concern among predominantly end-user buyers — a reason to verify rather than assume.
• IBEF's Feb 2026 report shows FY25 delivery volumes rising sharply, underscoring the value of asking precise, dated questions about your specific project.
• Log builder answers immediately via a tool like DrawMagic's AI Home-Buying Companion, so nothing is lost to memory.
• For anything you can't independently verify, consult a licensed legal or property professional before signing.
• DrawMagic presents public facts and helps you organize your own questions and findings — it does not verify, certify, or guarantee any builder or project.

FAQ

Q: What if the builder can't immediately provide the RERA number? A: Treat that as a reason to check the state RERA portal yourself by project name before proceeding, and ask again in writing — a genuinely registered project's number should be readily available.

Q: Is it rude to ask for everything in writing? A: No — asking for written confirmation of costs, timelines, and inclusions is a standard, reasonable part of any significant purchase, and a professional sales team will expect it.

Q: Should I ask these questions before or after seeing the show flat? A: Either order works, but many buyers find it easier to ask fact-based questions first, while they're still evaluating objectively, rather than after becoming emotionally attached to a specific unit.
