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 home.

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 2 homes carry one, and 12 of the 14 are recorded unsold. Since we started watching this ledger, 2 homes have moved out of the unsold list, most recently on 12 September 2026.

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.

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.

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.
