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.
Across MahaRERA, Keystone Realtors Limited is the promoter of record on 55 projects, of which 4 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.
MahaRERA's cost filing puts construction at ~10.9% of the estimated project cost incurred as of the last certificate (₹18.08 Cr spent against a ₹166.08 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.
Of 36 homes filed with MahaRERA, 5 are sold/booked and 31 remain available (~14% sold) — early in sales — more choice of units now, but confirm the developer has the pre-sales to fund the build. Buyers have committed ₹41.11 Cr in agreement value so far. Of that, ₹5.90 Cr (~14%) is already collected, ₹28.41 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 5 registered agreements, the effective carpet rate is ₹54,067/sqft (typical range ₹52,085–₹54,891) — 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:

|---|---|---|---|

No buyer complaints were on this project's MahaRERA record at the time of reading — a clean sheet worth re-checking near booking.
The promoter has declared 2 court cases on this project to MahaRERA. 1 is still pending. Litigation can cloud the land title or stall the build — have a lawyer pull the cause list for each and confirm whether it touches the title to your flat. This is declared by the promoter; there may be further cases not on the RERA record.
| Court | Case no. | Year | Status |
|---|---|---|---|
| Honble City Civil Court Mumbai | 87 | 2023 | Closed |
| Deputy Registrar Cooperative Societies | dated 28th August 2023 | 2023 | Pending |
