5 RERA Red Flags That Mean You Should Walk Away From a Property

1What RERA Covers, and What It Does Not

The Real Estate (Regulation and Development) Act, 2016, came into force across India on May 1, 2017. It was the first central legislation to bring structured accountability to residential property development, a sector that had for decades operated with minimal transparency and significant information asymmetry between builders and buyers.

RERA does several things well. It mandates project registration before any sale or advertisement. It requires builders to disclose project timelines, carpet area definitions, approved plans, and financial details in a public portal. It establishes a grievance mechanism with quasi-judicial powers. It defines a standardised carpet area calculation that cannot be inflated with lobby space, wall thickness, or balconies.

What RERA does not do is guarantee delivery. A builder can be fully RERA-registered and still fail to complete a project. The portal records obligations and disclosures. Whether those obligations are met depends on the builder's financial health, construction capacity, and management integrity, none of which RERA can mandate into existence.

This is why verifying RERA registration is the beginning of due diligence, not the end. The portal contains far more information than most buyers examine. The five red flags described in this guide are all visible in the public RERA portal, at no cost, before you pay a single rupee. Ignoring them because the broker says "RERA registered hai" is one of the most expensive shortcuts a homebuyer can take.

The table below summarises the five red flags covered in this guide, the risk each one signals, and the severity level from a buyer's perspective.

2Red Flag 1: The Project Is Not Registered on the RERA Portal

This is the most fundamental check and, despite being the simplest to perform, it is the one most often skipped by buyers who accept a broker's verbal assurance. Under Section 3 of the RERA Act, any real estate project where the plot area exceeds 500 square metres or where there are more than 8 apartments across all phases must be registered before any advertisement, marketing, or sale can legally occur.

The practical consequence of buying in an unregistered project is severe. Every protection RERA provides, including standardised carpet area definitions, mandatory escrow of buyer funds, grievance redressal at the RERA authority, and the right to withdraw with full refund under Section 18, applies only to registered projects. In an unregistered project, a buyer is effectively back in the pre-RERA era, relying solely on the sale agreement and civil courts for recourse.

Builders occasionally argue that a project is exempt because it involves renovation of an existing structure, or because the plot area is below the threshold on paper (while the actual development clearly exceeds it). If a builder claims exemption and the project appears to involve new construction of multiple apartments, treat this as a red flag until an independent legal opinion confirms the exemption is legitimate.

To verify: go to Karnataka RERA and search by the project name or the promoter entity name exactly as stated on the builder's brochure. The registration number format for Karnataka is PRM/KA/RERA/[district code]/[year]/[serial]. If no registration appears, or if what appears is for a different phase or a differently named entity, do not proceed without a written explanation from the builder's legal team.

3Red Flag 2: The Possession Date Has Been Revised Two or More Times

Every RERA-registered project must declare a completion date at registration. The RERA portal tracks revisions to this date. A single extension, particularly one that occurred during 2020 to 2021 (the documented period of construction disruption due to COVID-19), is not inherently alarming. RERA Section 6 provides a legitimate force majeure extension pathway of up to one year.

What changes the risk profile is a pattern of revisions. If a project registered in 2019 with a stated possession date of December 2022 now shows a revised possession date of March 2025 and has already revised once before, this indicates that the original timeline was not grounded in realistic construction capacity or financing. Each revision often signals that the builder was selling future inventory to fund current construction, a fragile model that fails when new sales slow down.

The RERA portal in Karnataka records each revision with a timestamp. Cross-reference the revision dates with the quarterly construction progress reports the builder is required to upload. If the construction progress reports show consistent reporting of milestones achieved but the possession date keeps moving, the reports themselves may not accurately reflect site reality. A builder who files quarterly updates claiming 70% construction completion but has revised the possession date twice should prompt you to visit the site in person and compare what you observe with what the documents state.

For buyers evaluating resale flats in projects that are already completed, this red flag applies at the time of the original purchase rather than now. However, if you are buying a resale unit in a project that was significantly delayed and the seller is exiting, it is worth understanding the context of that delay before assuming the project is now risk-free.

4Red Flag 3: No Escrow Account Declaration or Evidence of Fund Diversion

Section 4(2)(l)(D) of the RERA Act is one of its most significant structural protections: builders must deposit at least 70% of all amounts collected from buyers into a designated bank account, to be used exclusively for land cost and construction costs of that specific project. The remaining 30% can be withdrawn for the promoter's use.

The rationale is straightforward: before RERA, builders routinely collected money from buyers in Project A and used it to acquire land for Project B, service debt from Project C, or fund the promoter's lifestyle. When Project A faced cost overruns, there was no ring-fenced capital to complete it. The escrow rule was designed to break this cross-subsidisation pattern.

In practice, the escrow rule is imperfectly enforced. However, there are observable signals of non-compliance. On the RERA portal, builders are required to disclose the designated escrow bank and account number at registration. If this field is blank or contains a generic current account number rather than a project-specific account, ask the builder's finance team for the escrow account statement. If they cannot or will not produce one, that is a material red flag.

Karnataka RERA also requires quarterly statements showing amounts deposited into and withdrawn from the escrow account. Download the most recent quarterly report for the project and check: does the declared amount collected from buyers align with 70% of that figure being held in the escrow account? A significant shortfall, unless the builder can demonstrate RERA authority approval for withdrawal, suggests fund diversion.

5Red Flag 4: The Carpet Area in the Brochure Does Not Match the RERA Filing

Before RERA, builders used a range of area definitions to quote apartment sizes: super built-up area, built-up area, saleable area, and carpet area. The ratio of carpet area to super built-up area (the "loading factor") varied from 20% to as high as 45% in some projects, meaning buyers were routinely paying for large amounts of common area infrastructure as part of their flat's stated size.

RERA Section 2(k) defines carpet area precisely: the net usable floor area within the walls of an apartment, including internal partitions but excluding external walls, service shafts, open terraces, and exclusive open balcony area. This is the only area definition builders can use for pricing in RERA-registered projects.

The red flag appears when a builder's marketing brochure advertises a "3BHK of 1,450 sqft" but the RERA portal filing for the same flat type shows a carpet area of 1,050 sqft. The difference is the loading factor. The brochure number is the super built-up area. The RERA number is what you actually get.

When comparing prices across projects, always compare on a per-sqft-of-carpet-area basis, not on the brochure's super built-up area. A project quoting Rs 7,500/sqft on super built-up may be equivalent to Rs 10,700/sqft on carpet area if the loading factor is 30%. The PakkaBhav transaction database uses carpet area where available and clearly labels the area basis for every registered transaction so you can make meaningful comparisons.

Beyond loading factors, also check whether the RERA filing for your specific unit matches the floor plan the builder has shown you. Floor plans sometimes change between booking and construction. If the builder has revised the floor plan post-booking without your written consent, this is a violation of RERA Section 14, which prohibits any material alteration to plans without the consent of at least two-thirds of allottees.

5Red Flag 5: The Builder Has Pending Complaints or Unexecuted RERA Orders

The RERA complaint mechanism was intended to give buyers a faster, cheaper alternative to civil litigation. Complaints are filed by allottees, heard by the RERA adjudicating officer or authority, and orders are typically issued within 60 days of filing. When a builder fails to comply with a RERA order, the authority can attach assets, issue recovery certificates, and refer the matter for prosecution.

The Karnataka RERA portal's public complaint section shows all filed complaints against a registered project, including their current status: pending, disposed, or under execution. Before purchasing in any project, search the complaint register for the project name and the promoter entity name.

A single complaint in a large project may reflect an isolated dispute and need not be disqualifying on its own. What demands serious scrutiny is any of the following: multiple complaints filed by different buyers against the same project within a short period (indicating a systemic issue rather than an individual grievance), orders passed against the builder that remain unenforced (indicating the builder is not complying even with tribunal directives), or complaints that allege fraud or misrepresentation rather than ordinary delays (a materially different category of risk).

It is also worth checking the promoter entity name, not just the project name. A builder group may operate multiple projects under different company names. If the parent group has enforcement proceedings or RERA deregistration orders against it in another state, this context is highly relevant to evaluating the risk of a new project by the same group, even if the specific new project has a clean record.

7How to Verify Each Red Flag Before Signing

The five red flags above are not abstract principles. Each one has a specific, publicly accessible data source that allows any buyer to verify the signal in under thirty minutes. The following steps translate each red flag into a concrete verification action.

Two additional verification steps sit outside the RERA portal but are equally important. First, verify that the project has received its Commencement Certificate (CC) from the planning authority, which is a prerequisite for legal construction. Builders sometimes begin construction before receiving a CC and then retroactively obtain one. If the CC date on the RERA portal is after the builder's stated construction start date, this irregularity warrants scrutiny.

Second, before committing to a project, check what buyers have actually paid for registered transactions in the same project or in comparable projects in the same locality. The builder's current asking price should be consistent with what Sub-Registrar records show for recent transactions. If the asking price is significantly above registered transaction prices for similar configurations in the same project, this discrepancy is worth understanding before signing. Use the PakkaBhav transaction search to see verified registration data from the Kaveri portal for societies in Bengaluru.
