Hidden Charges When Buying a Flat in Mumbai — Complete Cost Breakdown 2026

The Real Cost of Buying a Flat in Mumbai

Most first-time homebuyers in Mumbai focus only on the base price of the property. They budget for the EMI, arrange the down payment, and think they are ready. Then the hidden charges start appearing — stamp duty, registration, GST, maintenance corpus, parking fees, legal charges, and a dozen other expenses that can add 15-25% to the total cost.

A flat advertised at Rs. 1 crore in Mumbai can easily end up costing Rs. 1.2 crore or more once all charges are included. Understanding these costs upfront helps you plan your finances better and avoid last-minute surprises. This guide breaks down every possible charge you may face when buying a flat in Mumbai in 2026.

Government Charges

Stamp Duty

Stamp duty is the single largest additional cost. In Maharashtra, stamp duty rates for 2026 are: 5% for men and 4% for women on properties up to Rs. 30 lakh; 6% for men and 5% for women on properties above Rs. 30 lakh. On a Rs. 1 crore flat, expect to pay Rs. 50,000-60,000 in stamp duty.

Registration Charges

Registration charges are 1% of the property value, capped at Rs. 30,000. This is mandatory for legally recording the transaction.

GST on Under-Construction Properties

For under-construction properties, GST is applicable at 5% on affordable housing (carpet area up to 60 sq m, value up to Rs. 45 lakh) and 12% on other residential properties. On a Rs. 1 crore under-construction flat, GST of approximately Rs. 1.2 lakh is payable. Ready possession flats are exempt from GST.

TDS on Property Purchase

If you buy a property worth Rs. 50 lakh or more, you must deduct TDS at 1% of the total consideration and deposit it with the Income Tax Department. The builder provides you with Form 16B for this deduction.

Builder and Developer Charges

Maintenance Security Deposit

Most builders charge a one-time maintenance security deposit at the time of possession. This typically ranges from Rs. 50,000 to Rs. 2 lakh depending on the project and flat size. This amount is held by the society and used for building maintenance.

Corpus Fund

A corpus fund is a one-time payment to the housing society for major repairs and renovations. The amount is usually 25-50% of the annual maintenance charges multiplied by a certain number of years. Expect Rs. 25,000-1,00,000 depending on the project.

Parking Charges

Parking is often sold separately from the flat. In Mumbai, covered car parking can cost Rs. 3-15 lakh depending on the location and project. Some builders include one parking slot in the base price, but second parking or premium parking is always charged extra.

Power Backup and Generator Charges

Many builders charge separately for power backup infrastructure. This can range from Rs. 20,000 to Rs. 50,000 per flat. Some include it in the maintenance deposit, while others bill it separately.

Clubhouse and Amenity Charges

If the project has a clubhouse, gym, swimming pool, or other amenities, there may be a one-time membership fee. This ranges from Rs. 25,000 to Rs. 2 lakh depending on the facilities.

PLC (Preferential Location Charges)

Flats with preferred locations — corner units, park-facing, sea-facing, or floors above a certain level — attract PLC. These charges can add Rs. 50-500 per square foot to the base price. A park-facing 2 BHK may cost Rs. 5-15 lakh more than a similar flat on a lower floor.

Legal and Documentation Charges

Legal Fees

Most homebuyers hire a lawyer to verify the title deed, review the agreement, and handle registration. Legal fees range from Rs. 10,000 to Rs. 30,000 depending on the property value and lawyer's experience.

Agreement Drafting

The builder charges for drafting the agreement for sale. This typically costs Rs. 5,000-15,000 and is separate from legal fees.

Society Transfer Fee

When you buy a resale flat, the housing society charges a transfer fee to record the change in ownership. This ranges from Rs. 5,000 to Rs. 25,000 depending on the society.

Notary and Franking Charges

Various documents need notarisation and franking. Budget Rs. 2,000-5,000 for these expenses.

Loan-Related Charges

Loan Processing Fee

Banks charge a processing fee of 0.25-1% of the loan amount. On a Rs. 80 lakh loan, this could be Rs. 20,000-80,000. Some banks waive this during festive offers.

Technical and Legal Valuation Fees

Banks conduct technical and legal valuation of the property before approving the loan. These fees range from Rs. 5,000 to Rs. 15,000 combined.

CERSAI Charges

A nominal fee of Rs. 50-100 for registering the charge on the Central Registry of Securitisation Asset Reconstruction and Security Interest.

Loan Insurance

Banks may push for loan protection insurance. This is optional but adds to the cost if taken. Premium ranges from Rs. 10,000-50,000 depending on loan amount and tenure.

Other Charges

Interior Modification Costs

Builders typically provide basic finishing. For modular kitchen, wardrobes, false ceilings, and other customisations, budget Rs. 3-10 lakh depending on the scope.

Moving and Shifting Costs

Budget Rs. 10,000-50,000 for packing, transportation, and unpacking services.
