In today's real estate market, under-construction properties are attracting numerous homebuyers with their modern amenities, customizable layouts, and competitive pricing. While these properties offer significant advantages over ready-to-move homes, they also come with unique challenges that first-time buyers often overlook. This comprehensive guide will help you navigate the potential pitfalls of investing in under-construction properties in India, ensuring your dream home doesn't become a financial burden.
Why Under-Construction Properties Are Popular
Under-construction properties typically offer:
- More affordable prices compared to ready-to-move properties
- Modern amenities and contemporary designs
- Flexible payment plans
- Customization opportunities
- Potential for appreciation during the construction period
However, these benefits come with certain risks that require careful consideration before making your investment decision.
7 Common Mistakes to Avoid When Buying Under-Construction Property
1. Ignoring GST Implications
Many first-time buyers fail to account for Goods and Services Tax (GST) when calculating the total cost of an under-construction property. Currently, GST rates are:
- 1% for affordable housing
- 5% for non-affordable housing
For example, if you're purchasing a non-affordable apartment worth ₹60 lakh, you'll need to pay an additional ₹3 lakh as GST. Failing to include this amount in your budget planning can significantly impact your finances.
2. Not Verifying Amenity Completion Timelines
While developers eagerly showcase impressive amenities during their sales presentations, these facilities are often completed long after residents have moved in.
When Rahul and Priya moved into their new apartment in Noida, they were disappointed to discover that the promised clubhouse, swimming pool, and children's play area wouldn't be ready for another 8 months. Make sure to:
- Get written confirmation of amenity completion dates
- Check if there are penalties for delays in amenity completion
- Visit other completed projects by the same developer to assess the quality of similar amenities
3. Overlooking Resale Opportunities
While buying directly from a developer seems straightforward, sometimes purchasing from an existing investor can offer better value. Investors looking to exit early might sell at discounted rates compared to the developer's current pricing.
In Pune, Amit found that he could purchase a 2BHK apartment from an investor at ₹5,150 per sq ft when the developer was selling similar units at ₹5,750 per sq ft—saving him nearly ₹6 lakh on a 1,000 sq ft apartment.
4. Having No Clear Exit Strategy
Many buyers don't consider their exit options before investing. Understanding the builder-buyer agreement clauses regarding property transfer is crucial, especially if unexpected circumstances require you to sell before completion.
Key questions to ask:
- Is there a lock-in period before you can sell?
- What are the transfer charges if you sell before possession?
- Can you assign your booking to another buyer?
5. Misunderstanding Payment Plans and Penalty Clauses
Developers offer various payment structures, each with its own advantages and penalty clauses:
- Down Payment Plan: Requires 10-15% upfront payment with the remainder due within a specified timeframe
- Construction-Linked Plan: Payments made in installments as construction progresses
- Time-Linked Plan: Fixed payments at predetermined intervals regardless of construction progress
Be particularly vigilant about penalty clauses for:
- Late payments (typically 12-18% interest per annum)
- Delayed possession acceptance
- Agreement breaches
For instance, if you miss a ₹5 lakh installment payment by three months with an 18% penalty clause, you could owe an additional ₹22,500 in penalties.
6. Not Understanding Cancellation and Refund Policies
Historically, many developers had harsh cancellation policies with minimal refunds. However, a recent Supreme Court ruling limits the deduction to 10% of the base price upon cancellation.
If you pay ₹15 lakh for a ₹75 lakh property and later cancel, the builder can legally retain only ₹7.5 lakh (10% of the base price), not the entire amount paid.
Still, many builders try to impose higher penalties, so ensure the refund policy in your agreement complies with current legal standards.
7. Being Unclear About Customization Limitations
Before signing the agreement, have detailed discussions about:
- What modifications are allowed
- Which changes incur additional costs
- What structural alterations are prohibited
Deepika and Rajesh wanted to combine their kitchen and dining area in their under-construction apartment in Bangalore, only to discover that removing the partition wall wasn't permitted due to structural concerns. Having this conversation early would have influenced their buying decision.
8. Not Securing Proof of Interest Payments
When reserving a unit with a token amount (Expression of Interest), always:
- Get a proper receipt
- Understand the conditions for refund
- Confirm the amount will be adjusted against the total cost
- Use traceable payment methods (avoid cash)
Additional Critical Considerations
RERA Registration Verification
Always verify that the project is registered with the Real Estate Regulatory Authority (RERA). This provides legal protection and ensures the developer complies with established guidelines.
Builder Reputation and Track Record
Research the developer's history regarding:
- Timely delivery of past projects
- Quality of construction
- Response to customer complaints
- Financial stability
Legal Documentation
Have all documents reviewed by a property lawyer, including:
- Builder-buyer agreement
- Payment schedules
- Possession timelines
- Penalty clauses
- Specifications of materials and fittings

Project Financing
Check if the project has secured funding from reputable financial institutions. Banks conduct thorough due diligence before financing construction projects, so their involvement adds a layer of security to your investment.
Conclusion
While under-construction properties offer numerous advantages like modern amenities and competitive pricing, they require careful consideration to avoid costly mistakes. By being vigilant about GST implications, amenity timelines, payment plans, and legal protections, you can make a well-informed decision that aligns with your financial goals and housing needs.
Remember that your dream home should be a source of joy, not stress. Taking the time to research thoroughly and understand all aspects of your purchase will help ensure a smooth and satisfying home-buying experience.
