Counts and agreement value as the promoter filed them at the last compliance date; this is the filed inventory, not current availability. Of that agreement value, ₹5.07 Cr (about 50%) is recorded as collected and ₹5.10 Cr as receivable. The registration lists 108 homes; this inventory lists 93. These are separate filed records. Their counts do not match; neither count establishes today's availability.

Filed agreement values: across 28 sold or booked entries with usable filed values and areas, the effective carpet rate is ₹9,097/sqft, with eight in ten falling between ₹8,867 and ₹9,267 — computed from the agreement values and carpet areas the promoter filed, not broker quotes.

The inventory filing also declares: 15 not for sale.

What the filings record, home by home

Read from MahaRERA on 17 October 2026

This unit list contains 108 entries; the separate sales summary contains 93. The lists can differ in status coverage and filing date. Use the source date shown with each.

MahaRERA publishes, home by home, what this promoter filed: which homes 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 home. On this project 29 homes carry one, and 64 of the 108 are recorded unsold. Since we started watching this ledger, 3 homes have moved out of the unsold list, most recently on 11 September 2026.

Here is one home filed as unsold, beside the amounts filed for comparable homes:

HomeCarpetFiled comparisonBased on
1101359 sqftRs 32.13 lakh typical, over Rs 26.00 lakh to Rs 32.87 lakh8 filed · number pattern + area (within 2%), same building

A filed consideration is the amount the promoter reported for one home. 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 home 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 Opal Annex, 42 of the 64 unsold homes 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.
