What is Property Due Diligence?
Buying a home is likely the largest financial decision of your life. Due diligence is the non-negotiable investigation you must do before committing any money. It is the process of verifying that what the seller or builder is telling you is legally, financially, and physically true.
In India, property disputes — from double sales and forged title documents to illegal construction and undisclosed mortgages — are extremely common. The vast majority of these disputes could have been avoided with proper due diligence conducted before purchase. Once you sign and register, reversing a bad property purchase is expensive, time-consuming, and often impossible.
Never rely only on the bank's due diligence: Banks conduct a legal and technical check as part of home loan processing — but their check protects the bank's interest, not yours. They may approve loans on properties with title defects that don't affect their security. Always do your own independent due diligence before relying on a bank's approval as confirmation of property quality.
Due Diligence for New / Under-Construction Projects
✅ RERA & Legal Checks
RERA Registration: Verify project on your state RERA portal. Note possession date, number of approved units, and project status (Active/Lapsed).
Land Title: Builder must show clear title to the land — sale deed, development agreement, power of attorney chain must be verified by your lawyer.
Commencement Certificate: Confirms local authority has approved the builder to start construction. Project without CC is illegal to build.
Approved Building Plan: Verify that the plan sanctioned by the authority matches what is being built — floor count, setbacks, FSI usage.
No Litigation: Search court records for any cases against the builder or the specific project land.
Bank Escrow: Confirm the project has a dedicated escrow account where 70% of collections are deposited per RERA rules.
🏗️ Builder Track Record
Past Project Delivery: Visit or call residents of the builder's last 3–5 completed projects. Were they delivered on time? Was the quality as promised?
RERA Complaints: Check the state RERA portal for complaints filed against this builder — number, nature, and resolution.
Financial Health: Check if builder is listed on NCLT insolvency portal. Check for any defaults to banks or NBFCs in public records.
Credit Rating: If available (CRISIL, ICRA), check the builder's credit rating — BBB or above is acceptable; below is risky.
Due Diligence for Resale Properties
📋 Title & Legal Checks
Title Chain (30 years): Trace ownership from original sale to current seller. Every transfer must have a registered deed — gaps in the chain are red flags.
Encumbrance Certificate: Get EC for 30 years from Sub-Registrar. All mortgages must have corresponding discharge entries.
Original Title Documents: Demand originals of all title documents — if seller says originals are with bank, get bank NOC confirming loan closure.
Khata / Property Card: Verify khata is in the current owner's name. Discrepancy between title and khata indicates mutation has not been done.
Property Tax Receipts: Verify property tax is paid up to date and in the current owner's name. Arrears become your liability after purchase.
Society NOC: Get a No Objection Certificate from the housing society confirming no dues are pending from the current owner.
Occupancy Certificate: Confirm OC has been received for the building. Without OC, the building is technically unauthorised.
🔧 Physical & Technical Checks
Physical Inspection: Visit the flat at different times — morning, evening, and monsoon if possible. Check for seepage, cracks, water pressure, ventilation.
Structural Assessment: For older buildings (15+ years), get a structural engineer's assessment before purchase.
Actual Carpet Area: Measure the flat. Verify it matches the carpet area in the sale deed and registration documents.
Parking: Confirm parking space is allocated in the sale deed — not just verbally promised. Verify it is clearly marked and accessible.

Frequently Asked Questions
Due diligence is the process of thoroughly verifying all legal, financial, and technical aspects of a property before purchase. It includes checking RERA registration, title deed chain, encumbrance certificate, approved building plans, builder track record, and the property's physical condition. Skipping due diligence is the single most common cause of property disputes in India.
Key documents to verify: RERA registration certificate, title deed and mother deed (30-year chain), encumbrance certificate, approved building plan, commencement certificate, occupancy certificate (for ready properties), khata/property card, property tax receipts, and the builder-buyer agreement. For resale, also check housing society NOC and share certificate.
Yes, strongly recommended. A property lawyer who specialises in real estate can review title documents, identify red flags in the chain of ownership, interpret encumbrance certificates, and flag issues in the builder-buyer agreement. Use your own independent lawyer — not the one recommended by the builder or seller, whose interests may conflict with yours.
A thorough due diligence typically takes 1–4 weeks depending on document availability and complexity. Getting the encumbrance certificate takes 1–7 days. Title deed verification by a lawyer takes 3–7 days. Builder track record research can be done in 2–3 days. Never let a seller pressure you into skipping or rushing due diligence — urgency is a common sales tactic.
No. Bank approval means the bank is satisfied the property has sufficient value to secure their loan — it does not guarantee a clear title or legal compliance. Banks may approve loans on properties with incomplete OCs, pending RERA violations, or title disputes that don't directly affect their mortgage. Always conduct your own independent due diligence regardless of bank approval.
