Introduction
Buying a flat involves interacting with builders, agents, banks, and sellers. The questions you ask determine the information you get. Here are the questions that protect your interests.
Questions for the Builder
1. "What is the exact carpet area, not super built-up?"
Why ask: You pay per square foot, but builders often quote super built-up area which includes common areas.
What to expect:
- Carpet area = actual usable space
- Super built-up = carpet + walls + share of common area
- Loading can be 25-40%
Follow-up: Get carpet area in writing in the agreement.
2. "Can I see the RERA registration certificate?"
Why ask: RERA registration is mandatory and shows project legitimacy.
What to verify:
- Registration number
- Project name matches
- Approved units count
- Completion timeline
Red flag: Builder hesitates or says "registration in process."
3. "What is the construction-linked payment plan?"
Why ask: Your payment should match construction progress.
Ideal structure:
- Booking: 10%
- Foundation: 10%
- Each slab: 10-15%
- Finishing: 10%
- Possession: 5-10%
Red flag: Large upfront payments, time-linked plans.
4. "What are ALL the charges beyond base price?"
Why ask: Hidden charges can add 15-25% to advertised price.
Get written breakdown of:
- Preferential location charges
- Floor rise charges
- Car parking (open/covered)
- Club membership
- Development charges
- Legal and documentation
- GST
- Maintenance deposit
5. "What happens if you miss the possession date?"
Why ask: Delays are common; you need protection.
Expect:
- Grace period (6 months maximum)
- Compensation rate per month
- Interest on payments made
- Your right to exit with refund
RERA standard: Interest at SBI MCLR + 2%.
Questions for Yourself
6. "Can I afford the EMI even if my income drops 20%?"
Why ask: Job loss or health issues can affect income.
Test:
- EMI should be < 35% of income
- 6 months' EMI in emergency fund
- No other major financial commitments
Reality check: Banks approve more than you should borrow.
7. "Have I visited the location at different times?"
Why ask: Morning and night experiences can be vastly different.
Check at:
- Morning rush hour: Commute reality
- Evening: Noise, safety, lighting
- Weekend: Parking, crowds
- Monsoon: Waterlogging, road condition
Questions for the Society (Resale)
8. "What are the pending dues and monthly maintenance?"
Why ask: You inherit pending dues; monthly costs affect affordability.
Get in writing:
- Current monthly maintenance
- Any pending dues from seller
- Upcoming major expenses (painting, lift replacement)
- Sinking fund balance
- Planned maintenance increase
9. "Can I see the society's financial statements?"
Why ask: Reveals society's financial health.
Check for:
- Regular audits
- Fund balances
- Pending litigations
- Major upcoming expenses
- Defaulter list
Question for Your Lawyer
10. "Is there anything in these documents that concerns you?"
Why ask: Lawyers see patterns you don't.
Areas lawyer should check:
- Title clarity
- Agreement fairness
- Unusual clauses
- Missing documents
- Potential disputes
Cost: ₹10,000-25,000 for thorough review.
Value: Prevents lakhs in future losses.
Bonus Questions
For Agent:
- "What's your commission and who pays it?"
- "Why is the seller selling?"
- "How long has this been on market?"
For Neighbors:
- "How has your experience been?"
- "Any major issues with builder/society?"
- "Would you buy here again?"
For Bank:
- "What's your valuation of this property?"
- "Any concerns with the project?"
- "What's the effective interest rate including processing?"
Red Flag Responses
Be cautious if you hear:
- "Don't worry about the details"
- "This is how everyone does it"
- "Price will increase tomorrow"
- "Many buyers are interested"
- "We don't negotiate on this"
- "Pay in cash for discount"
- "Documents are with the bank"
- "Registration can be done later"
Conclusion
Asking questions is not being difficult – it's being smart. Any seller or builder who resists legitimate questions is hiding something. Your questions today prevent your problems tomorrow.
