Total Cost of Buying a 3 BHK Flat in Bengaluru: The Complete All-In Breakdown

The all-in cost of buying a 3 BHK flat in Bengaluru is routinely 8 to 15% higher than the advertised base price. Buyers who budget only for the advertised rate are routinely surprised at the point of registration. This guide gives you a complete, itemised breakdown of every cost involved in buying a new builder 3 BHK in Bengaluru, with worked examples at three price points: Rs.90 lakh, Rs.1.5 crore, and Rs.2.5 crore.

Base Price, Floor Rise and PLC Charges

The developer’s advertised rate is the Base Selling Price (BSP) for the ground floor or a reference floor. Additional price components typically added to BSP:

PLC charges can meaningfully inflate the all-in cost. A park-facing 3 BHK at Rs.1.2 crore BSP with Rs.200 per sqft PLC on a 1,500 sq ft unit adds Rs.3 lakh to the base cost. Ask for a full cost sheet (also called a payment plan sheet) that includes all PLCs and floor rise before comparing across projects. KRERA mandates developers disclose this in the project disclosure document at rera.karnataka.gov.in.

GST on Under-Construction Flats

GST applies only to under-construction (UC) properties. Ready-to-move (RTM) properties with a valid Occupancy Certificate attract zero GST. For UC properties in Bengaluru:

• Standard rate: 5% GST on the agreement value (no ITC)
• Affordable housing rate: 1% GST, applicable only if carpet area is maximum 60 sq metres AND the total price is maximum Rs.45 lakh AND the project is KRERA-registered as an affordable project. Most Bengaluru 3 BHK units exceed 60 sq metres carpet area, so this rate rarely applies.
• Parking and club membership: These are charged 5% GST even when charged separately if they are part of the same supply as the flat.

GST is computed on the all-inclusive price (BSP + PLC + floor rise + car parking + club) in most interpretations. Confirm with your developer how GST is computed in their specific payment structure. For a Rs.1.5 crore under-construction 3 BHK, GST alone is Rs.7.5 lakh.

Stamp Duty and Registration in Karnataka

Karnataka stamp duty and registration charges are among the higher in India for properties above Rs.45 lakh:

• Stamp duty: 5% + 10% surcharge on stamp duty = effective 5.5% for properties above Rs.45 lakh (Karnataka Budget 2023 onward). No separate concession for women buyers in Karnataka (unlike many other states).
• Registration fee: 1% of the agreement value, capped at Rs.1 lakh maximum.

Stamp duty is computed on the higher of agreement value or guidance value. Guidance values (BBMP/BDA-set minimum values by locality) in inner Bengaluru corridors like JP Nagar and Banashankari are often close to market rates. In outer corridors like Devanahalli and outer Sarjapur Road, market rates are typically higher than guidance values, so stamp duty is computed on the market rate. Use kaveri.karnataka.gov.in to check guidance values before computing stamp duty.

Car Parking, Club, and One-Time Developer Charges

One-time charges that many buyers forget to budget for:

• Corpus fund: Rs.50,000 to Rs.3 lakh one-time deposit for the RWA’s maintenance reserve. Mandatory in most projects, often non-refundable.
• Legal and documentation charges: Rs.15,000 to Rs.50,000 charged by the developer for sale agreement drafting and registration assistance.
• BESCOM connection deposit: Rs.15,000 to Rs.30,000 for the electrical connection in your unit.
• Meter installation: Rs.5,000 to Rs.15,000 depending on load requirement.
• Home loan processing fee: 0.25 to 1% of the loan amount (Rs.12,500 to Rs.1,00,000 depending on loan size and bank).

Home Loan Processing and Related Costs

If buying with a home loan, factor these costs:

• Processing fee: 0.25 to 1% of loan amount (typically Rs.15,000 to Rs.50,000 for a Rs.75 lakh loan)
• Technical and legal valuation: Rs.5,000 to Rs.15,000 charged by the bank
• Property insurance: Lender-mandated; Rs.8,000 to Rs.25,000 per year depending on loan and property value
• Pre-EMI interest during construction: For disbursed tranches before possession, banks charge interest on the disbursed amount only. On Rs.30 lakh disbursed at 8.75% for 12 months, pre-EMI interest totals approximately Rs.2.6 lakh.

For 3 BHK buyers in Whitefield, Hebbal, and Hennur Road who take large home loans of Rs.80 lakh to Rs.1.5 crore, the pre-EMI interest on staggered disbursals during a 2 to 3 year construction period can add Rs.5 to Rs.12 lakh to total cost.

Post-Possession Costs

Costs to budget for at and after possession:

• Interiors and modular kitchen: Rs.8 to Rs.30 lakh depending on scope. A standard modular kitchen with wardrobes and basic furniture in a Bengaluru 3 BHK runs Rs.10 to Rs.18 lakh for a decent finish.
• Maintenance deposit: Some developers charge 2 to 3 months advance maintenance at possession. On Rs.6,000 per month, this is Rs.12,000 to Rs.18,000 advance.
• Property tax: Bengaluru property tax (BBMP) on a 3 BHK in the Rs.90 lakh to Rs.2 crore range is typically Rs.15,000 to Rs.45,000 per year, paid in two instalments.

Worked Examples at Rs.90L, Rs.1.5Cr, Rs.2.5Cr

The all-in cost runs 17 to 18% above the advertised base price for under-construction 3 BHK flats in Bengaluru. For ready-to-move properties, remove the GST component and the total premium drops to approximately 12 to 13% above base.

Interiors and furnishings add a further Rs.10 to Rs.25 lakh post-possession. Always ask the developer for a full all-inclusive cost sheet before comparing projects and confirming your loan eligibility. Cross-check all project details at rera.karnataka.gov.in before booking.

How much is stamp duty for a flat in Bengaluru in 2024?

On a Rs.90 lakh flat, stamp duty is approximately Rs.4.95 lakh plus 10% surcharge = Rs.5.45 lakh, and registration is Rs.90,000 (below the Rs.1 lakh cap). Stamp duty is computed on the higher of the agreement value or BBMP/BDA guidance value. Check guidance values at kaveri.karnataka.gov.in before budgeting.

What is GST on a 3 BHK flat in Bengaluru?

Under-construction 3 BHK flats in Bengaluru attract 5% GST on the agreement value with no ITC claimable by individual buyers. Ready-to-move flats with a valid Occupancy Certificate attract zero GST. Most Bengaluru 3 BHK units exceed the 60 sq metre carpet area limit for the 1% affordable housing GST rate, so the standard 5% rate applies. GST is typically computed on the total agreement value including car parking and club membership charges.

What are the hidden charges when buying a flat in Bengaluru?

The main charges beyond the advertised base price are: floor rise premium (Rs.25 to Rs.400 per sqft per floor above the base floor), Preferential Location Charge for corner or park-facing units (Rs.50 to Rs.500 per sqft), mandatory car parking (Rs.3 to Rs.12 lakh), club membership (Rs.1.5 to Rs.5 lakh one-time), corpus fund (Rs.50,000 to Rs.3 lakh), BESCOM connection deposit (Rs.15,000 to Rs.30,000), and legal and documentation fees charged by the developer (Rs.15,000 to Rs.50,000). Ask for a complete all-inclusive cost sheet from the developer before booking.

Should I buy under-construction or ready-to-move in Bengaluru to save on costs?

Ready-to-move (RTM) with an OC saves 5% GST, which is a real saving of Rs.4.5 lakh on a Rs.90 lakh property. However, RTM properties are typically priced 5 to 15% above under-construction prices for a similar quality project. The net cost difference depends on the specific properties being compared. RTM also eliminates pre-EMI interest during construction (Rs.2 to Rs.8 lakh saving over 2 to 3 years) and rent paid while waiting for possession. For buyers currently renting, the time-cost of waiting 2 to 3 years for a UC property often outweighs the GST saving. See Whitefield and Sarjapur Road for both UC and RTM options across budget ranges.
