The Era of One-Sided Penalties
Before RERA, Builder-Buyer Agreements were notoriously skewed in favor of developers. If a builder delayed handing over possession of a flat by several years, they typically offered a meager compensation of ₹5 to ₹10 per square foot. However, if a homebuyer delayed an installment payment by even a few days, the builder would charge exorbitant interest rates, often ranging from 18% to 24% per annum.
The Real Estate (Regulation and Development) Act, 2016 completely dismantled this unfair practice by introducing the "Rule of Parity."
The Rule of Parity in Interest Rates
Under the RERA guidelines, equality is strictly enforced. The Act mandates that the rate of interest payable by the promoter (for delayed possession) and the allottee (for delayed payments) must be exactly the same.
If the agreement states that a buyer must pay 10.5% interest for defaulting on an installment, the builder is legally bound to pay that exact same 10.5% interest if they fail to deliver the flat on time.
How is the Interest Rate Calculated?
RERA does not allow builders to arbitrarily set this interest rate in their contracts. Instead, the rate is standardized and prescribed by the respective State Real Estate Regulatory Authorities.
While minor variations exist between states, the universally adopted formula is the State Bank of India’s Marginal Cost of Funds-based Lending Rate (SBI MCLR) plus 2%.
- Example Calculation: If the current SBI MCLR is 8.5%, the applicable interest rate under RERA would be 10.5% per annum.
- Application: If you miss a payment milestone by two months, the builder can only charge you this state-prescribed rate (e.g., 10.5% p.a.) on the delayed amount, calculated for those specific two months.
Consequences of Non-Payment by the Buyer
While RERA protects buyers from predatory interest rates, buyers must still adhere to their payment schedules.
- Cure Period: If you miss a payment, the builder will issue a demand notice adding the RERA-prescribed interest. You are expected to clear the dues along with the interest.
- Cancellation: If a buyer continuously defaults on multiple payments and ignores formal notices, the builder retains the right to unilaterally cancel the allotment. Upon cancellation, the builder can deduct the earnest money (usually capped at 10% of the property value) and must refund the remaining balance to the buyer within the statutory timeline.
Always ensure you opt for a "Construction-Linked Payment Plan" rather than a time-linked plan, so that your payment demands are strictly tied to actual physical progress on the site.
