Mumbai's housing market had a strong September. The city recorded 12,622 property registrations during the month, according to a Knight Frank India report. That is 5 per cent higher than the 12,070 units registered in September 2025. It is also the highest figure for the month in more than 14 years.
The month also edged past August. Registrations rose 0.3 per cent from the 12,580 units recorded in August 2026. The data covers the area under the Brihanmumbai Municipal Corporation (BMC) and includes both new sales and resale deals. Knight Frank compiles it from the Maharashtra government's Department of Registrations and Stamps.
Festival season did the heavy lifting
Ganesh Chaturthi, which ran from September 14 to 25, drove much of the month's activity. Mumbai recorded 5,379 registrations in those 12 days. The same period last year saw 4,392. That is a rise of 22 per cent and the best festive-period tally in four years.
The festival also mattered for revenue. Stamp duty collected during these days made up more than half of the total generated in September.
Shishir Baijal, Chairman and Managing Director of Knight Frank India, said the city's residential market has held on to its demand momentum. He called out the festival period as a notable contributor to the month's overall numbers.
A long climb since 2013
The September figures show how far the market has come. Registrations stood at 4,116 units in September 2013. They crossed the 10,000 mark in September 2023, at 10,694 units. September 2025 reached 12,070, which was then the best September in a decade. This year's 12,622 sets a new high. That is about three times the 2013 level.
Volume and revenue are not moving together
There is one point buyers and developers should note. Registrations are rising, but stamp duty income is not keeping pace. Zee Business reports that registrations are growing while stamp duty income is falling. The report also points to a shift in the mix of property transactions, even as demand in the housing market stays steady.
The data does not say what is behind the shift. It could reflect changes in the share of resale deals, in ticket sizes, or in both. Knight Frank's numbers alone do not settle this.
What the numbers say
September's registrations tell a simple story. More Mumbai homes changed hands this September than in any September in over a decade and a half. Festive buying added a clear boost, and the month still came out ahead of August.
For the market, the next test is the coming festive months. Last year, Navratri 2025 saw 6,238 registrations, so that period will be a useful yardstick. Whether volumes hold up, and whether revenue catches up with them, will show how durable this run is.
