Premium Home Buying Due Diligence Checklist for India (40 Points)

You have found the apartment. The light is perfect, the view is rare, and the builder is pressing for a token "to hold it for you." This is exactly the moment to slow down. The single most expensive mistake a first-time premium buyer makes is paying a token before the paperwork is verified — and in India, where one defective link in a 30-year title chain can unravel a ₹5-crore purchase, that mistake is irreversible.

This is your complete property due diligence checklist for India. Forty concrete checks across four pillars — legal title, statutory approvals, technical condition, and financial structuring — that every discerning buyer should clear before any money leaves your account. Work through them in order. If even one cannot be answered with a document in hand, treat it as a red flag, not a formality.

Why due diligence matters more at the premium end

At the premium end, the risk is not that the deal is bad — it is that the deal looks immaculate. Glossy brochures, a reputed builder name, and a polished sales lounge create a halo that discourages questions. But a strong brand does not guarantee a clean title to your specific unit, a valid Occupancy Certificate, or a society with no pending litigation. Due diligence is how you convert trust into proof.

In 2026 the stakes are also procedural. Maharashtra now levies penalties up to ₹1 lakh for insufficient stamp duty, and both buyer and seller must complete real-time Aadhaar-based biometric authentication at registration. The system is tightening. Your paperwork must be flawless.

Pillar 1 — Legal & title due diligence (14 checks)

This is the foundation. If the title is defective, nothing else matters.

1. Mother deed / title deed chain — Trace ownership back at least 30 years (12 years minimum if older records are genuinely unavailable). Every transfer must link cleanly to the next.
2. Current seller's title — Confirm the person selling is the legally recorded owner, with the sale deed in their name.
3. Encumbrance Certificate (EC) — Obtain a digitally signed 30-year EC. It proves the property is free of mortgages, liens, and registered dues.
4. Conversion / land-use certificate — Confirm the land is legally converted for residential (or commercial) use and is not agricultural.
5. Khata / property record / 7-12 extract — Verify the property is recorded in the seller's name in municipal and revenue records.
6. Mutation entries — Check that every past ownership change was correctly recorded (mutated) in government records.
7. Development Agreement & Power of Attorney — If a developer built on owned land, verify the DA and any registered PoA are valid and unrevoked.
8. No-litigation search — Confirm there are no pending court cases, partition suits, or third-party claims on the property.
9. Society / association NOC — For resale, obtain the housing society's No-Objection Certificate and confirm no transfer restrictions.
10. Outstanding dues NOC — Maintenance, water, and society dues fully cleared, in writing.
11. Legal heir / family consent — Where the property was inherited, confirm all legal heirs have consented to the sale.
12. Approved sale agreement draft — Have your own lawyer draft or vet the agreement; never sign the builder's standard format unread.
13. Power-of-attorney sales — Be extra cautious. Insist on a registered, specific (not general) PoA and verify the principal is alive and competent.
14. Bank/NBFC charge release — If the property was ever mortgaged, obtain the original loan-closure and charge-release documents.

Pillar 2 — Statutory & RERA approvals (10 checks)

A clean title on land with no building permissions is still a liability.

15. RERA registration — Verify the project (and the unit) is registered on your state's RERA portal. Cross-check the registration number, promoter, and project completion date.
16. RERA complaint history — Search the promoter's name on RERA for past or pending complaints. A pattern of delays is a strong signal.
17. Approved building plan — Confirm the sanctioned plan from the local planning authority matches what is actually built.
18. Commencement Certificate (CC) — For under-construction homes, the CC must be issued before any construction (and any payment) is legitimate.
19. Occupancy Certificate (OC) — For ready/resale homes, the OC is non-negotiable. No OC means the building is legally uninhabitable, and you cannot get utilities or resale clarity.
20. Completion Certificate — Confirms the building was finished per the sanctioned plan.
21. Environmental clearance — Required for larger projects; verify it exists where applicable.
22. Fire safety NOC — Mandatory for high-rises. Confirm the fire department's approval.
23. Layout & zoning compliance — Confirm the unit's use matches the zoning (no commercial use in a residential-zoned tower, and vice versa).
24. Carpet area declaration — Under RERA, pricing must be on carpet area. Verify the carpet area in writing and check it against the agreement.

Pillar 3 — Technical & physical due diligence (8 checks)

Approvals confirm the building should be sound. These checks confirm it is.

25. Structural condition — For resale or older premium stock, commission a structural assessment for cracks, seepage, and load-bearing integrity.
26. Construction quality vs. spec sheet — Match delivered finishes, fittings, and materials against the agreement's specification annexure.
27. Carpet vs. super built-up — Physically verify the usable carpet area; do not pay premium per-square-foot rates on inflated super built-up figures.
28. Water source & supply — Confirm a legal, reliable water source (municipal connection, not solely tankers).
29. Power load & backup — Verify sanctioned electrical load and DG-backup capacity for premium amenities.
30. Parking allotment — Confirm parking is legally allotted in writing; stilt/covered parking cannot be sold as a standalone unit but must be clearly assigned.
31. Amenities handover — Confirm clubhouse, pool, and common areas are completed and have OC coverage, not merely "promised."
32. Boundary & survey verification — Match the physical boundaries and survey number to the title documents to rule out encroachment.

Pillar 4 — Financial, tax & NRI structuring (8 checks)

The money side is where premium buyers leave the most value — and the most exposure — on the table.

33. Stamp duty & registration budget — In Mumbai, budget 6% stamp duty (5% for women buyers) including Metro Cess; in Pune, Thane, and Nagpur it is 7% (6% for women) including Metro Cess and Local Body Tax. Registration is 1%, capped at ₹30,000 for properties above ₹30 lakh.
34. Women-buyer concession — A 1% stamp duty concession applies when residential property is registered solely in a woman's name. (Joint ownership with a male co-owner attracts the standard rate; the earlier 15-year resale restriction has been removed.)
35. Ready reckoner vs. agreement value — Ensure your agreement value is not below the government ready reckoner rate, or you will face a stamp-duty shortfall — and a potential penalty of up to ₹1 lakh.
36. TDS on purchase — For resident sellers, deduct 1% TDS where consideration exceeds ₹50 lakh. When buying from an NRI seller, TDS is far higher — 20% (plus cess) on long-term gains, 30% on short-term — so insist on the seller's PAN and any lower-TDS certificate.
37. Home loan sanction & legal vetting — Even if you can pay cash, a lender's independent legal and technical appraisal is a free second opinion on title and valuation.
38. FEMA compliance (NRI/OCI buyers) — NRIs and OCIs can buy residential and commercial property freely, with no RBI permission, but cannot purchase agricultural land, farmhouses, or plantations. PAN is mandatory, and funds must route through NRE/NRO/FCNR accounts.
39. Repatriation planning (NRI) — Plan the source of funds in advance: repatriation of sale proceeds from an NRO account is capped at USD 1 million per financial year.
40. All-in cost reconciliation — Tally base price + stamp duty + registration + GST (under-construction) + parking + clubhouse + brokerage + legal + GST on services into one number before you commit. The headline price is rarely the real price.

Frequently asked questions

What is the most important document to verify before buying a home in India?

The title chain and a digitally signed 30-year Encumbrance Certificate. Together they prove the seller genuinely owns the property and that it is free of mortgages, liens, and undisclosed claims. For ready homes, the Occupancy Certificate is equally non-negotiable.

Can an NRI buy any property in India?

NRIs and OCIs can buy residential and commercial property freely without RBI permission, funding the purchase through NRE, NRO, or FCNR accounts. They cannot buy agricultural land, farmhouses, or plantation property — these can only come through inheritance or gift.

How much should I budget for stamp duty and registration in Maharashtra in 2026?

In Mumbai, budget roughly 6% stamp duty (5% for women buyers) plus 1% registration. In Pune, Thane, and Nagpur, it is about 7% (6% for women) plus registration, which is capped at ₹30,000 above ₹30 lakh. Never set agreement value below the ready reckoner rate, or you risk a penalty of up to ₹1 lakh.

Is a RERA registration number enough to trust a project?

No. The RERA number is the starting point, not the conclusion. Always verify the registration details on the official state portal, check the promoter's complaint history, and confirm the Commencement Certificate (under-construction) or Occupancy Certificate (ready) separately.

When should I do due diligence — before or after paying a token?

Always before. A token, once paid, is rarely refundable and creates emotional pressure to overlook problems. Complete the full title, approval, technical, and financial checks first, then commit.
