What buyers actually paid: across 159 registered agreements, the effective carpet rate is ₹11,262/sqft, with eight in ten falling between ₹9,756 and ₹12,554 — computed from the agreement values and carpet areas the promoter filed, not broker quotes.

What the filings record, home by home

Read from MahaRERA on 19 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 176 homes carry one, and 58 of the 234 are recorded unsold. Since we started watching this ledger, 17 homes have moved out of the unsold list, most recently on 11 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
201537 sqftRs 52.50 lakh typical, over Rs 39.89 lakh to Rs 64.02 lakh27 filed on this stack, floors 3–31

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 Sai Proviso Atlantis Phase I, every one of the 58 unsold homes has agreements filed on its 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 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.
