A project page tells you what was promised. The RERA Karnataka quarterly update tells you how it is going. Every three months a Karnataka promoter must file where construction stands, floor by floor and tower by tower, how many flats are booked and how many are still for sale, and what money came in from buyers and went out of the project account. It is the closest thing to a progress report a buyer gets before possession, and it is filed under oath. This guide shows how to read one, how to date it, and what to ask when the figures do not add up.
Key takeaways
- Quarterly updates are filed on 2,311 RERA Karnataka registrations, and 1,601 of them had filed the July to September 2026 quarter, as updated on 19 October 2026.
- An update is due within 15 days of the quarter's end; the median was filed exactly 15 days after it, and 76 percent were on time.
- Each update gives the completion percentage of every floor of every tower, flats booked and available by type, and the money collected from buyers and withdrawn.
- Read the money lines across quarters, not alone: promoters do not all report them the same way, so ask whether a figure is for the quarter or to date.
Date the update first
The first thing to read is not a percentage but the quarter. An update from two quarters ago describes a building that has moved on, or has not, since. Of the 2,311 registrations that file quarterly updates, this is where the latest one stood as updated on 19 October 2026:

An update is due within 15 days of the end of each quarter. Across the 6,914 updates on the register, the median was filed exactly 15 days after the quarter ended, 76 percent arrived within 15 days, and 86 percent within 45. A project whose newest update is two quarters old is behind on its own obligation, and the authority now prices that: according to a TeamLease RegTech summary of its February 2026 circular, each update missed or filed late for the quarters from 2017 to March 2025 carries a penalty of Rs 25,000. The page shows up to the last four quarters, so you can also see whether the promoter files steadily.
What an update contains
Progress by floor and tower. A completion percentage for each floor of each tower, and for the tower as a whole. Read the bottom floors against the top: a tower whose ground floor is at 85 percent and whose sixth is at 0 is at the structure stage, whatever the brochure's photographs suggest.
Bookings by flat type. For each tower, the number of 1BHK, 2BHK, 3BHK and other units, how many are booked and how many available, with the same for parking. Across the latest updates of the 1,673 registrations that total their units, 209,753 were recorded as booked and 153,991 as available, 57.7 percent booked; the median project stood at 46.2 percent. Booked is the register's word, and it is not the same as sold: a booking can be cancelled before an agreement is registered.
The money. The advance collected from buyers and the amount withdrawn from the project account, alongside the estimated and actual cost lines. Under the RERA Act, 70 percent of what buyers pay must go into a separate account and can be withdrawn only in proportion to the work done, certified by the engineer, the architect and the chartered accountant; the 70 percent account and Form 3 withdrawals explains the rule.
The one thing to know about the money lines
Read them across quarters, and do not assume every promoter files them the same way. In 1,488 of 4,603 pairs of consecutive updates, the advance collected went down from one quarter to the next, which a running total cannot do. Some promoters appear to report the quarter's collection and others the total to date. Neither is wrong on its face, but it means a single figure tells you little. If the advance collected is lower than last quarter's, or the amount withdrawn is higher than the advance collected, ask the promoter which basis the figures use and what the account holds besides buyer money.
Screenshot the quarterly updates on the day you book. The page shows only the last four quarters, so the update you relied on will eventually drop off, and your screenshot is the record of what was filed when you paid.
If you are following a project before you book, a free account keeps it in a shortlist you can open on any device, so you can come back to its page after the next quarter's update.
Older pages often show none
Quarterly updates appear mainly on registrations made in the register's newer page format. Of the registrations described as New Project Launch or Ongoing, 2,129 newer-format pages show updates and 1,807 do not; of the older-format ones, only 171 show updates and 3,203 do not. An older page with no quarterly tab is not proof the promoter stopped filing, but it means you have to ask for the latest progress report directly.
An analogy: the scorecard at each drinks break
In a long cricket match nobody waits for the last ball to know who is ahead. At every break the scorecard shows runs, wickets and overs left. A quarterly update is that scorecard: construction is the runs, bookings the wickets taken, the money the overs used. One scorecard tells you the position. Four in a row tell you the run rate, and the run rate is what tells you whether the target will be reached by the date on the registration.
Ananya and Karthik compare two scorecards
Names and numbers in this story are illustrative. Ananya and Karthik put the latest updates for their two shortlists side by side. The first, filed in October for July to September, put tower B at 64 percent with floors up to the twelfth started, and 181 of 220 flats booked. The second was filed for January to March, two quarters old, with its tower at 22 percent and the amount withdrawn higher than the advance collected. The second promoter's sales office said construction had "picked up a lot". Karthik asked for the April to June and July to September updates. Until they arrived, the first project was the only one they were still considering.
How to read an update, in order
- The quarter and the filing date. Is it the latest quarter?
- Tower completion. Then the floors, bottom to top, for the tower your flat is in.
- Bookings for your flat type. Booked against available, compared with the last update.
- Money lines. Collected and withdrawn, across quarters, asking the basis if anything looks odd.
- Against the completion date. Is the pace consistent with the date on the registration? If not, see what each status means and RERA rules for delayed possession.
The same report in other states is described in quarterly progress reports explained. Where the quarterly tab sits among the portal's other checks is in how to check a project on RERA Karnataka, and where it falls in the purchase is stage eight of buying a flat in Karnataka. The market around these numbers is moving: ANAROCK put Bengaluru's sales at about 16,670 units in July to September 2026, up 12 percent on a year earlier.
