What you can check here

We turn dense government registry data into plain answers a home buyer can act on.

Builder track record

Every developer gets a delivery grade based on how reliably they finish projects on time across all their registrations.

Delays & overruns

See exactly how late finished projects were, and how far past deadline ongoing projects have slipped — in months, not jargon.

Deadline extensions

Repeated extensions are an early warning sign. We surface how many times a deadline was pushed back and by how long.

Complaints on record

Count of buyer complaints filed against a project or builder on the official RERA registry.

How to read it

Three numbers tell most of the story.

Delivery grade (A–F)

A quick summary of a builder's reliability. A means strong on-time delivery; F means a poor record. Always open the project list to see the detail behind the grade.

Delay vs overdue

“Delay” is for finished projects that were handed over late. “Overdue” is for ongoing projects that are already past their deadline.

Promised vs revised deadline

The original promised date is what the builder committed to. A later revised date means the deadline was extended.
