Filed agreement values: across 61 sold or booked entries with usable filed values and areas, the effective carpet rate is ₹5,033/sqft, with eight in ten falling between ₹4,075 and ₹5,838 — computed from the agreement values and carpet areas the promoter filed, not broker quotes.

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 22 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 61 units carry one, and 132 of the 193 are recorded unsold.

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

UnitCarpetFiled comparisonBased on
C-wing Shop4466 sqftRs 23.25 lakh typical, over Rs 21.00 lakh to Rs 28.00 lakh14 filed · similar area (within 2%), elsewhere in project

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. Only one observation of this ledger so far: no change can be reported yet. This observation is an archived copy whose time is the moment the file was written, not a portal fetch time.

In ALTAMONTE, 119 of the 132 unsold units have 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.

What to verify before you book

  1. Confirm the MahaRERA registration is live and read the project page on the MahaRERA portal for the sanctioned plan, approvals and the promoter's quarterly progress reports.
  2. Check the declared completion date against actual site progress — registration is not the same as a delivered, occupancy-certified building.
  3. Verify the exact carpet area, floor and unit number in your agreement match the sanctioned plan (not the brochure's saleable area).
  4. Confirm the title, the 7/12 land extract and that your payments go to the project's designated RERA escrow account.

Registration details and regulatory notices are drawn from the held MahaRERA record. See more Mumbai, Thane & the MMR projects.
