Buying a 3 BHK apartment is often seen as a dream move—more space, more comfort, and a symbol of lifestyle success. However, while many buyers plan around the base price or EMIs, they often overlook several hidden costs that can significantly impact the overall budget. If you're planning to invest in a 3 BHK, especially in prime urban areas, here are the lesser-known expenses you need to account for.

1. Maintenance Charges

Most apartment complexes charge monthly or quarterly maintenance fees, which can range from ₹2 to ₹6 per sq. ft. for basic apartments and even higher in luxury high-rises. This covers security, water supply, power backup, and upkeep of common areas.

Tip: Always ask the builder or seller for a detailed breakdown of ongoing maintenance costs.

2. Floor Rise Charges

Planning to live on a higher floor for better views and ventilation? Be ready to pay a premium. Builders often add a floor rise charge per floor—typically ₹25 to ₹50 per sq. ft.—which can make a noticeable difference in total cost.

3. Parking Fees

A 3 BHK usually means a family with more than one vehicle, but most apartments only offer one parking slot by default. Extra parking spaces can cost ₹2 to ₹6 lakhs, depending on the location and type (open or covered).

4. Clubhouse & Amenity Charges

Modern 3 BHK apartments in gated communities come with facilities like gyms, swimming pools, and community halls—but these aren’t free. Builders often charge a one-time fee or include it in the sale price as ‘amenity charges.’

5. GST on Under-Construction Properties

If you're buying an under-construction flat, be ready to pay 5% GST on the total sale value (without ITC). This can add a substantial amount to your cost, especially in metro cities.

6. Legal & Registration Charges

Stamp duty and registration fees vary from state to state (5–8% of property value), and so do legal and documentation charges. Don’t forget the cost of hiring a legal expert to verify property papers—it’s essential but often overlooked.

7. Interior & Furnishing Expenses

The apartment cost is just the beginning. Modular kitchens, wardrobes, lighting, furnishing, and décor can easily add ₹10–30 lakhs to your final bill, especially for a spacious 3 BHK setup.

8. Society Formation and Sinking Fund

Some developers require buyers to contribute to the society’s corpus or sinking fund, which is used for long-term repairs or upgrades. This one-time fee can range from ₹25,000 to ₹1 lakh, depending on the project scale.

9. Loan-Related Hidden Charges

Home loans come with processing fees, legal verification costs, and sometimes hidden foreclosure or part-payment penalties. Always read the fine print of your home loan agreement.

10. Tax Implications & Annual Property Tax

Annual property taxes vary based on city and property size. Larger units like 3 BHKs attract higher tax slabs. Check your local municipal corporation's rates to budget accordingly.

A Real Example: 3 BHK in Gurgaon

Let’s say you're eyeing a 3 BHK in Gurgaon priced at ₹1.2 crores. By the time you add GST, stamp duty, parking, interiors, and other charges, your real spend could be closer to ₹1.45–₹1.5 crores. That’s nearly a 20–25% increase over the advertised base price!

Final Thoughts

Buying a 3 BHK is a milestone, but understanding the complete financial picture ensures your decision is truly informed. Always factor in these hidden costs before finalizing your home loan or property deal. That way, you’ll enjoy the space and comfort of your dream home without unpleasant financial surprises.
