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, ₹4.88 Cr (about 9%) is recorded as collected and ₹49.47 Cr as receivable. The project registers 264 homes in total, while this sold/unsold inventory filing covers 242 of them.

What buyers actually paid: across 52 registered agreements, the effective carpet rate is ₹18,074/sqft, with eight in ten falling between ₹14,844 and ₹19,195 — computed from the agreement values and carpet areas the promoter filed, not broker quotes.

The inventory filing also declares: 22 owner/investor-held.

What the filings record, home by home

Read from MahaRERA on 20 September 2026

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 the sold ones the registered agreement value — the consideration filed for that specific home. On this project 67 homes carry one, and 175 of the 264 are recorded unsold. Since we started watching this ledger, 27 homes have moved out of the unsold list, most recently on 12 September 2026.

Here is one of those unsold homes, priced against what buyers of the same home on other floors actually filed:

HomeCarpetFiled for the same home on other floorsBased on
3702643 sqftRs 1.1746 cr typical, over Rs 81.66 lakh to Rs 1.3774 cr41 filed at this size

A filed consideration is what was registered 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 WINDSOR TOWER A, 110 of the 175 unsold homes have agreements filed on their own stack. The Price Comparison Report gives each of them its own row — the filed agreements behind that stack listed in full, the government reckoner value the promoter filed against it, and whether it is mortgaged to a lender while still on the unsold list. Built from the filing itself, sent by email.

What to verify (inactive registration)

  1. Download the MahaRERA order stating the reason for deregistration or suspension — this is public on the portal.
  2. Check whether the developer has filed a challenge in the Appellate Tribunal and whether the order is stayed.
  3. Do not make any further payments until the registration status is restored or you obtain legal advice.
  4. Contact MahaRERA's helpdesk for guidance on alternative arrangements or pending dues.

Flags are from MahaRERA's own published problem lists — not a claim about the developer's intent. Explore every flagged project on our Mumbai, Thane & the MMR RERA red-flag register.
