Report coverage
K-RERA registry & builder-record report
What this report covers
To confirm directly with the builder
🔒 The verdict & buyer playbook · Compliance report
The paid report opens with the overall risk rating, the specific red-flag findings, exactly what I'd do as a buyer in this project, who it suits, and the questions to put to the builder before you commit.
Registration-form facts from the K-RERA detail page: use these to sanity-check the builder brochure, parking allotment, and sanctioned-plan references before relying on plan-extracted approximations.

K-RERA registration tables showing the project mix and tower/wing scale. Use this to sanity-check sales claims such as "only large homes", "low density", or "plenty of parking" against the filed inventory.

What the numbers tell you
Synthesis from the official RERA scale, unit register, and land rows — the read a sales team won't volunteer.
🔒 Unit-by-unit guidance · Unit Guidance report
Which block and unit to prefer, the livability read on the filed plans, and a plan-by-plan walkthrough — the ₹2,999 guidance layer.
🔒 Full records — land title, amenities paperwork & document catalog · Compliance report
The complete land-title chain, the paperwork behind each declared amenity, and every document row on file with the regulator — the raw records the compliance read is built on.
No litigation declared on this project's K-RERA filing.
All 20 standard compliance document slots have usable uploaded filings.
No completion certificate (OC) on file yet — project has not been declared complete.
⚠ Registration validity has lapsed: originally due 01 Jul 2021, extended (Covid Extension) to 01 Apr 2022 — both dates have passed with no OC on file. An extension application filed on 22 Jun 2022 is pending with K-RERA — until it is approved, the registration stands lapsed.
Named utility/regulatory approvals
"Not found in catalog" can mean the approval genuinely isn't on file yet, or that it doesn't apply to this project (K-RERA doesn't tell us which). Ask the builder directly for any marked not found before relying on it.

K-RERA names 3 project professional/vendor rows across Architect, Contractor, Structural engineer. Use this to cross-check whose certificates, drawings, and contractor commitments support the filing; final reliance still belongs with your lawyer/technical reviewer.

Mantri has 8 other K-RERA-registered projects in our records — grouped across the several project-specific entities this developer registers under (e.g. this project is filed as “Mantri Developers”). 8 are past their declared completion deadline with no completion certificate recorded — but because K-RERA publishes OCs inconsistently, a project that has actually been finished and handed over still shows up this way, so this overstates real delays, especially for a high-volume established builder. That is a higher delayed rate than the K-RERA average across Bengaluru on the same measure.
Read this as a list to spot-check for a pattern of genuinely stalled projects, not as a delay rate — pull up a few of the builder’s other K-RERA registrations and check whether they’ve actually been delivered.
⚠ No quarterly financial disclosures (collections, escrow withdrawals) on record, despite no completion certificate yet — meaning we can't verify the project's cashflows against its construction progress. Worth asking the builder directly why no quarterly filings are available.
Declared construction cost ÷ registered units averages to ₹266.5 lakhs per unit — the developer's own declared construction/development cost, not a sale price. K-RERA filings don't disclose what the builder is charging, so this can't tell you whether you're getting a fair deal — only you comparing your quoted price against comparable listings nearby can answer that.
RERA 70% project account is on file: Bank of Baroda Altamount Branch, Mumbai (IFSC BARB0ALTAMO, a/c …1045). RERA requires 70% of buyer collections to sit in this separate, project-specific account, drawn only against certified construction milestones — confirm your payments are made to THIS account (not a general builder account) and that it appears on your allotment letter.
K-RERA has 1 project-photo upload.
These are developer-uploaded progress photos in the official document catalog. We do not treat them as proof of current site condition; use them as a prompt to ask for newer dated photos or a site visit.
