Filed agreement values: across 24 sold or booked entries with usable filed values and areas, the effective carpet rate is ₹10,270/sqft, with eight in ten falling between ₹9,025 and ₹12,447 — computed from the agreement values and carpet areas the promoter filed, not broker quotes.

The units recorded as unsold on the filing. The reckoner value is the government's ready-reckoner assessment the promoter filed against that unit, the figure stamp duty is charged on. It is not a price anyone paid, not an asking price, and not a valuation of the unit.

No units are declared mortgaged, reserved, investor-held or not-for-sale in this inventory filing.

What the filings record, unit by unit

Read from MahaRERA on 17 October 2026

MahaRERA publishes, unit by unit, what this promoter filed: which units are sold and which are not, the RERA carpet area of each, and for sold or booked entries the filed agreement value — the consideration filed for that specific unit. On this project 24 units carry one, and 37 of the 61 are recorded unsold. Since we started watching this ledger, 10 units have moved out of the unsold list, most recently on 19 July 2026.

Here is one unit filed as unsold, beside the amounts filed for comparable units:

A filed consideration is the amount the promoter reported for one unit. It is not a valuation, and MahaRERA does not publish the date of any of these agreements — read a range as a spread, not as a trend. An unsold row means no sale had been filed for it when we looked, which is a filing state, not a promise that the unit is available to you today. One of the two observations is an archived copy whose time is the moment the file was written, not a portal fetch time.

In Kaustubh, every one of the 37 unsold units has filed sales to compare with. The Sales Report gives each of them its own row — the filed agreements behind its comparison listed in full, the government reckoner value the promoter filed against it, and mortgage status where the filing supplies it. Missing mortgage information is not confirmation that a unit is free of a mortgage. Built from the filing itself, sent by email.
