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, Ossia Developers is the promoter of record on 7 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.
MahaRERA's cost filing puts construction at ~84.9% of the estimated project cost incurred as of the last certificate (₹8,905 spent against a ₹10,493 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 66 homes filed with MahaRERA, 57 are sold/booked (55 with registered agreements + 2 booked) and 9 remain available (~86% sold) — nearly sold out — little inventory left, so you're buying into an established buyer base. Buyers have committed ₹60.62 Cr in agreement value so far. Of that, ₹47.41 Cr (~78%) is already collected, ₹13.17 Cr receivable — a read on how far along these sales really are. Note: the project registers 128 homes in total, but this sold/unsold inventory filing covers only 66 of them — the other 62 aren't in the ledger yet. Ask the builder what they are (an unreleased phase, held-back stock, or non-saleable/car-park units) before reading too much into the percentage. This is the promoter's own reported inventory as at the last compliance filing; confirm current availability directly.
What buyers actually paid: across 57 registered agreements, the effective carpet rate is ₹17,856/sqft (typical range ₹14,774–₹23,935) — 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:
| Floor | Unit | Carpet | Reckoner value |
|---|---|---|---|
| Floor 11 | 1102 | 642 sqft (59.64 sqm) | ₹77.92 Lakh |
| Floor 11 | 1105 | 531 sqft (49.33 sqm) | ₹64.45 Lakh |
| Floor 12 | 1202 | 620 sqft (57.59 sqm) | ₹75.25 Lakh |
| Floor 14 | 1401 | 665 sqft (61.78 sqm) | ₹80.72 Lakh |
| Floor 14 | 1404 | 405 sqft (37.62 sqm) | ₹49.15 Lakh |
| Floor 17 | 1704 | 405 sqft (37.62 sqm) | ₹49.15 Lakh |
| Floor 17 | 1704 | 405 sqft (37.62 sqm) | ₹54.07 Lakh |
| Floor 17 | 1705 | 627 sqft (58.25 sqm) | ₹76.11 Lakh |
| Ground/Floor 0 | 1 | 1,480 sqft (137.51 sqm) | ₹3.20 Cr |
No units are declared mortgaged, reserved, investor-held or not-for-sale in this inventory filing — still confirm your specific unit's status in the agreement.
