18 Bengaluru projects analysed from Karnataka RERA filings, quarterly updates and the K-RERA complaint register, as of September 11, 2026.
Mantri in one paragraph
Mantri has a weak delivery record in Karnataka RERA filings: 18% of registrations needed no extension (2 of 18 crawled Bengaluru registrations needed no extension). 15 of 15 under-construction projects are past their original RERA completion date, by 52 months on average (worst 80). The promoter entity carries 170 complaints at K-RERA across its projects. The median Mantri project scores 46/100 on investment merit (below the Bengaluru average); the best, Mantri Centrium, scores 57.
Delivery is judged on extensions filed, not on handover dates, because RERA records extensions reliably and handovers late. Extensions are common across Bengaluru; compare the rate with other developers below.
