Buying a home in Karnataka in 2026 is safer than it was a decade ago, thanks largely to the Real Estate (Regulation and Development) Act. The Karnataka RERA (K-RERA) portal now lists over 6,900 registered projects and more than 4,200 registered agents, making it the single most important tool a buyer has. Yet enforcement gaps remain, and a booking amount paid in haste can still turn into years of litigation. Here is exactly what you should verify before signing anything.

Confirm the RERA registration number first

Every project of more than eight units or 500 sq m must be registered with K-RERA. Before paying even a token advance, ask for the RERA registration number and cross-check it on rera.karnataka.gov.in.

On the portal you can verify:

  • The approved project layout and sanctioned plan
  • The completion date the builder has legally committed to
  • Quarterly progress updates the promoter must file
  • Any complaints or penalty orders against the project

If a project claims to be "RERA approved" but the number returns no result, treat it as an immediate red flag. In 2025, K-RERA issued recovery notices worth over Rs 180 crore against non-compliant promoters, so the risk of buying unregistered inventory is real.

Check the title and encumbrance history

RERA does not replace independent legal diligence. Insist on:

  • A 30-year title search by an advocate
  • The latest Encumbrance Certificate (EC)
  • Khata (A-Khata is preferable; B-Khata carries loan and resale restrictions)
  • Approvals from BBMP, BDA, BMRDA or the relevant local authority

Plots on the peripheries of Bengaluru, especially around Devanahalli, Sarjapur and Hoskote, frequently carry conversion or Khata issues. A clean A-Khata property in these corridors currently commands a 12-18% premium over comparable B-Khata stock for good reason.

Understand the carpet area, not the super built-up

RERA mandates that pricing be quoted on carpet area, not the inflated super built-up area builders once used. In prime Bengaluru micro-markets, expect these 2026 ranges on a carpet-area basis:

  • Whitefield: Rs 8,500-11,000 per sq ft
  • Sarjapur Road: Rs 7,800-10,500 per sq ft
  • Hebbal / North Bengaluru: Rs 9,000-12,500 per sq ft
  • Electronic City: Rs 6,500-8,500 per sq ft

Always compute the effective per-sq-ft cost on carpet area to compare projects fairly. A quoted "loading" above 30% deserves scrutiny.

Verify the escrow account discipline

Under RERA, 70% of buyer funds must sit in a project-specific escrow account and be used only for that project's construction. Ask the builder to confirm the escrow bank and account details in the agreement. This single provision has meaningfully reduced fund diversion, one of the biggest historical causes of stalled projects in Karnataka.

Read the sale agreement clauses carefully

The RERA model agreement fixes several buyer protections that older contracts lacked:

  • Delay compensation payable at the same interest rate a buyer would pay for a default
  • A five-year defect liability period for structural issues
  • Restrictions on unilateral changes to layout or common areas without consent

Do not accept a builder's private agreement that dilutes these clauses. If terms differ from the RERA norms, negotiate or walk away.

Assess rental yields if you are investing

For investors, gross rental yields in Bengaluru currently sit around 3.2-4.1%, higher than Mumbai or Delhi NCR. IT-corridor micro-markets like Outer Ring Road and Sarjapur deliver the stronger end of that range because of steady tenant demand from tech professionals. Yields alone rarely justify a purchase, so weigh them against expected capital appreciation, which has averaged 7-9% annually in well-connected corridors.

A quick pre-booking checklist

  • Valid K-RERA number verified online
  • Clear 30-year title and current EC
  • A-Khata and all civic approvals in place
  • Pricing quoted on carpet area
  • Escrow account named in the agreement
  • RERA-compliant sale agreement with delay penalties
  • Builder's past project delivery record checked on the portal

RERA has shifted the balance of power towards buyers, but only for those who use it. Spend a few hours on the portal and with a good property lawyer before you book, and you will avoid the vast majority of disputes that still land in the tribunal each year.
