10 Things to Check Before Buying a Flat in Mumbai (That Agents Won't Tell You)

Buying a flat is one of the biggest financial decisions you can make. Whether you are purchasing a new property or a resale flat, checking the legal documents, construction quality, society records, and total costs can help you avoid expensive problems later.

Before paying a token amount or signing an agreement, make sure you thoroughly verify the following:

1. Verify RERA Registration

Every eligible real-estate project in Maharashtra must be registered with MahaRERA.

You can verify the project's RERA registration number on the official MahaRERA website. The registration details can help you check important information such as:

• Approved project details
• Promoter or builder information
• Proposed completion timeline
• Registered plans and project details
• Project-related complaints and updates

Do not rely only on information provided in advertisements or by a broker. Always cross-check the project details yourself.

Tip: Make sure the RERA details on the property listing match the project you are actually planning to purchase.

2. Check the Title Deed

Before purchasing a property, verify that the seller has a clear and marketable title to the property.

A property lawyer should check the relevant ownership and title documents to determine whether there are any:

• Ownership disputes
• Existing loans or mortgages
• Legal claims
• Encumbrances
• Restrictions on transfer
• Previous ownership issues

Professional legal verification may cost a few thousand rupees, but it can potentially save you from much larger financial and legal problems later.

For a resale property, also verify that the person selling the property is the actual legal owner and that the ownership documents are consistent.

3. Check the Occupancy Certificate (OC)

For completed buildings, check whether the required Occupancy Certificate (OC) has been issued by the relevant authority.

The OC generally indicates that the completed building has received the required approval for occupation according to applicable regulations.

Before purchasing a completed flat, ask the seller or developer for the relevant OC and have the document verified.

Do not assume that a building is fully compliant simply because residents are already living there.

4. Compare Carpet Area, Not Just Super Built-up Area

Always understand the difference between carpet area, built-up area, and super built-up area.

Under RERA, developers are required to disclose the applicable carpet area for registered projects. Carpet area gives you a much better basis for comparing the actual usable area of different flats.

For example, two properties may both be advertised as approximately 1,000 sq. ft., but their actual carpet areas may be significantly different.

When comparing prices, calculate the price per sq. ft. based on carpet area rather than relying only on the advertised super built-up area.

5. Check Pending Society Dues

If you are buying a resale flat, check whether the current owner has any outstanding:

• Maintenance charges
• Water charges
• Electricity-related dues
• Property-related society charges
• Parking charges
• Other society payments

Ask the housing society or association for a written confirmation of outstanding dues wherever possible.

It is also a good idea to obtain a No-Dues Certificate or equivalent confirmation before completing the transaction.

6. Inspect Construction Quality and the Flat's Condition

For a resale property, inspect the flat carefully before making a final decision.

Look for signs of:

• Water seepage
• Dampness
• Cracks in walls or ceilings
• Plumbing problems
• Damaged flooring
• Electrical issues
• Poor ventilation
• Structural concerns

For an older or visibly problematic property, consider hiring a qualified structural engineer or building professional for an independent inspection.

A relatively small inspection cost can help identify problems that may otherwise become expensive repairs after purchase.

7. Understand the Society Rules

Before buying a flat, ask for the society's applicable bye-laws, rules, and regulations.

Different housing societies may have specific rules regarding:

• Pets
• Parking
• Renovations
• Renting or leasing
• Commercial activities
• Use of common areas
• Moving procedures
• Structural modifications

If you have specific requirements, such as keeping a pet, running a home-based business, or extensively renovating the property, confirm the applicable rules before committing to the purchase.

8. Check FSI and Future Development

Before purchasing a property, understand the development potential of the land and surrounding area.

Depending on the project and applicable development regulations, future construction or redevelopment may affect:

• Your view
• Natural light
• Ventilation
• Privacy
• Parking
• Common areas
• Overall surroundings

Ask the developer, society, or a qualified property professional about planned construction, redevelopment proposals, and other known development activity around the property.

For larger or complex projects, professional verification can help you understand the applicable FSI (Floor Space Index) and development permissions.

9. Calculate Stamp Duty, Registration and Other Costs

The purchase price is not the only cost involved in buying a property.

Your overall budget may also need to include:

• Stamp duty
• Registration charges
• GST, where applicable
• Brokerage
• Legal verification fees
• Loan processing charges
• Society transfer charges, where applicable
• Parking charges, where applicable
• Interior and renovation expenses

Stamp duty and registration charges in Maharashtra can vary depending on factors such as the property's location, transaction value, and applicable government rules.

Therefore, do not assume a fixed percentage for every property. Check the applicable charges for your specific location and transaction before finalizing your budget.

10. Understand Pre-EMI vs Full EMI

If you are purchasing an under-construction property with a home loan, understand how your lender will structure the payments.

With a pre-EMI arrangement, you generally pay interest on the loan amount that has been disbursed during the construction period. Full EMI payments may begin later, depending on the loan structure and lender terms.

Ask your bank or financial institution for a complete repayment schedule and compare:

• Total interest payable
• Loan disbursement schedule
• Pre-EMI period
• Full EMI start date
• Expected possession date
• Your monthly cash-flow requirements

Do not choose a payment structure solely because the initial monthly payment appears lower.

Bonus: Verify All Documents Before Paying

Apart from the checks above, maintain a complete copy of the property's important documents.

Depending on the property and transaction, these may include:

• Sale deed or agreement for sale
• Previous title documents
• Encumbrance-related records
• Property tax receipts
• Society documents
• No-dues confirmation
• Occupancy Certificate
• Approved plans
• RERA registration details
• Loan or mortgage closure documents, where applicable

Have important legal documents reviewed by a qualified property lawyer rather than relying only on verbal assurances from the seller, builder, or broker.

Final Word

Buying a flat should never be a rushed decision.

A property may look attractive because of its location, price, amenities, or interiors, but legal verification and document checks are just as important as the property itself.

Take the time to verify the property's RERA details, ownership documents, occupancy status, area measurements, society dues, construction condition, applicable charges, and loan terms before making your final decision.

If you are considering a property listed on Sastaghar, verified listings can make the initial property-search process easier by providing important property and verification information upfront. However, buyers should still review the relevant documents and complete their own legal and financial due diligence before completing a purchase.

A few hours of verification today can prevent years of legal, financial, and ownership problems tomorrow.
