The Ultimate 100-Point India Apartment Buying Checklist (RERA, Legal & Finance)

This is the definitive, India-focused checklist you must use before booking any apartment, covering everything from RERA compliance and land title to hidden costs and structural safety. Use this to ensure your investment is legally sound and structurally secure.

Note: This checklist is based on the latest RERA, GST, and Income Tax guidelines for the Indian real estate market (as of December 2024). Always consult a qualified lawyer.

A. Builder & Developer Background Check

  • Developer’s Legal Name – Confirm the exact registered name from the State RERA portal and MCA (Ministry of Corporate Affairs) records.

  • Past Track Record – Check at least 3 completed projects for delays, quality issues, and post-handover support.

  • Timely Delivery History – Compare promised vs. actual possession dates of past projects. Chronic delays are a major red flag.

  • Litigation Search – Search the developer’s name + “court case / RERA complaint” on RERA orders, NCLT, and consumer court portals.

  • Financial Strength – Look for credit ratings or check whether the project land is heavily mortgaged/pledged.

  • Quality of Earlier Construction – Visit at least one completed project and talk to existing residents about seepage and maintenance issues.

  • Brand Perception – Ask local bankers and brokers about the developer’s reputation in the city.

  • Customer Service Reputation – Check responsiveness at the enquiry stage; this often reflects post-handover service quality.

  • Project Category Alignment – Verify if the project matches the builder’s usual segment (budget, mid, or luxury).

  • Joint Development & Landowner Check – If the project is a joint development, verify landowner reputation and ensure no disputes exist.

B1. Core Title & Land Clearance

  • Clear Title Deed – Obtain a title search report from a competent property lawyer, tracing ownership for at least 30 years (Mother Deed).

  • Encumbrance Certificate (EC) – Confirm no mortgages, liens, or court attachments on the land (check last 15–30 years).

  • Khata Certificate – Verify property tax records are updated with the revenue authority.

  • Land Use & Conversion – Confirm land use is residential as per the city’s master plan. Check for DC Conversion Certificate if land was agricultural.

B2. RERA & Regulatory Compliance

  • RERA Registration Number – Verify the project and your agent are registered on your state’s official RERA portal.

  • RERA Project Status – Check the committed completion date and current construction status on the RERA portal.

  • RERA Disclosure Documents – Review RERA-uploaded documents such as draft agreements, carpet areas, approvals, and the project bank account details.

  • Phase-wise RERA Registration – If part of a larger township, ensure your specific tower or phase has its own RERA registration and committed deadline.

B3. Approvals & Certificates

  • Approved Building Plan: Verify the plan sanctioned by the local municipal authority.

  • Floor Plan Approval: Ensure your exact unit number/layout is part of the approved plan.

  • Commencement Certificate (CC): Required for all under-construction properties before work begins.

  • Occupancy Certificate (OC): CRITICAL: Insist on the OC for ready-to-move properties. No OC means it’s illegal to occupy.

  • Completion Certificate (CC): Confirms the project is completed as per the approved plan.

  • Environmental Clearance (EC): For large projects, verify EC from the State Environmental Impact Assessment Authority.

  • Fire Department NOC: Check fire safety compliance.

  • Aviation Authority NOC: If near an airport, check height restrictions clearance.

  • Utility NOCs: Water, sewage, and electricity board sanction clearances.

B4. Key Transaction Documents

  • Agreement of Sale (AoS) Draft: Have a lawyer vet the draft before signing. Check all terms, payment schedule, and possession date.

  • Sale Deed: The final legal document transferring ownership from seller to buyer (after registration).

  • Society Share Certificate: For apartment complexes, confirms your membership and ownership interest in the common amenities.

C. Apartment Area, Layout & Specifications

  • Built-up & Super Built-up Area (SBA): Understand how common areas are loaded to arrive at the SBA.

  • Carpet-to-SBA Efficiency: Calculate Carpet Area ÷ SBA. Aim for 70% or higher.

  • Functional Layout: Check natural light, cross-ventilation, and practical furniture placement.

  • Direction & Vaastu: Verify the exact orientation of the unit (living room, master bedroom) on the site.

  • Floor Level & Stack: Note if the unit is above noise-generating areas (gym, transformer, STP).

  • Ceiling Height: Check clear floor-to-ceiling height (ideally 9.5–10 ft).

  • Wall & Flooring Specs: Confirm the brand/type of tiles and anti-skid bathroom flooring mentioned in the annexure.

  • Kitchen Provisions: Check for counter length, gas pipeline (if any), and water purifier provision.

  • Bathrooms & Plumbing: Verify CP & sanitary brands, proper hot/cold pipeline, and ventilation.

  • Doors & Windows: Confirm material (solid wood, UPVC/aluminium) and whether mosquito meshes are included.

  • Acoustic & Privacy: Ask about wall thickness between flats for sound insulation.

D3. Plumbing & Electrical Inspection

  • Water Pressure: Test all faucets and showers for adequate pressure and hot water functionality.

  • Drainage: Check all sinks, toilets, and showers for proper drainage and no leaks under the sinks.

  • Electrical Panel: Proper labeling, no corrosion, and adequate capacity.

  • Outlets & Switches: Ensure all outlets are functional, properly grounded, and switches work without buzzing.

  • Wiring Condition: Check for exposed wires or signs of inadequate insulation.

  • Earth Leakage Circuit Breaker (ELCB): Ensure installed and functional for safety.

E. Pricing, Taxes & Hidden Costs

F. Home Loan & Finance Planning

  • Interest Rate Type: Decide between floating and fixed, and understand the rate reset frequency.

  • Processing Fees & Hidden Charges: Compare processing fees, legal/valuation charges across different lenders.

  • Subvention Schemes: Be cautious; understand who pays the interest during construction and the risk of builder delay.

  • Stage-wise Payment: Ensure loan disbursals are strictly linked to construction milestones certified by the lender’s technical team.

  • Prepayment & Foreclosure: Confirm charges (usually nil for floating-rate individual borrowers, but verify).

  • Tax Benefits (Old Regime): Check eligibility for ₹2 lakh deduction on interest (Sec 24(b)) and ₹1.5 lakh on principal (Sec 80C).

  • Choice of Tax Regime: Run the numbers to see if the old or new tax regime is more beneficial considering home loan deductions.

  • Escrow Account Details: Ensure ≈70% of payments are deposited into the RERA-mandated project escrow account.
