Regulatory Standing

MahaRERA's own defaulter/deregistration lists and the project's quarterly-progress-report filing — the regulator's view of whether this project is in good standing.

Builder Track Record

Across MahaRERA, Naminath Erector And is the promoter of record on 2 projects, of which none currently carry a MahaRERA regulator flag (insolvency, deregistration, completion-lapse or QPR default). Read the pattern across the portfolio, not just this project's brochure — matched on the promoter name in the MahaRERA register.

Construction Progress

MahaRERA's cost filing puts construction at ~91.3% of the estimated project cost incurred as of the last certificate (₹38.33 Cr spent against a ₹42.00 Cr estimate). This financial % is the regulator's own proxy for how much is physically built — the closest public read on real progress, and one a brochure never shows.

Cost-incurred % as last certified to MahaRERA; it can lag on-site reality between filings. Confirm the current stage and the latest Form 2 before you book.

Sales & Inventory

Of 57 homes filed with MahaRERA, 32 are sold/booked and 25 remain available (~56% sold) — selling steadily. Buyers have committed ₹35.90 Cr in agreement value so far. Of that, ₹32.79 Cr (~91%) is already collected, ₹3.11 Cr receivable — a read on how far along these sales really are. This is the promoter's own reported inventory as at the last compliance filing; confirm current availability directly.

What buyers actually paid: across 32 registered agreements, the effective carpet rate is ₹27,002/sqft (typical range ₹23,376–₹27,006) — computed from the agreement values and carpet areas the promoter filed, not broker quotes. Compare your quote against this before negotiating.

The unsold units on the filing — if you're quoted a unit NOT on this list, ask why it shows as sold/booked on the RERA record:

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.
