Third Mumbai (KSC New Town): Real Estate and Investment Outlook

Where the project actually stands

Government of Maharashtra, by notification dated 15th October 2024, appointed MMRDA as New Town Development Authority for 124 villages in Uran, Panvel and Pen Tehsil in Raigad District of Maharashtra, with the designated area named K.S.C. New Town, comprising 323.44 sq.km of area. The Government of Maharashtra, vide a Government Resolution dated 16/03/2026, approved the Land Acquisition and Land Allocation policy for the New Town Development Authority and future projects implemented by MMRDA.

MMRDA has initiated the land acquisition process for the project, inviting landowners across the 124 villages to submit consent for surrendering their land parcels, with online consent forms made available from 27 April 2026, marking the formal start of acquisition. A public notification regarding land acquisition was, as of that point, expected to be issued shortly — meaning the statutory acquisition notice itself had not yet been formally issued as of that stage. Master plan finalisation is targeted for August 2026, which is when a GIS-based zoning map and development strategy are meant to set the stage for infrastructure rollout.

What can and cannot legally be bought right now

Nothing in the KSC New Town footprint has reached the stage of an authority-issued, RERA-registered residential or commercial plot layout as of mid-2026. What exists instead is a live land-acquisition/consent process on private agricultural holdings.

• Cannot yet be bought: any officially allotted or MMRDA-sanctioned plot inside the KSC boundary — none has been released for sale by the authority.
• Legally sensitive to buy: privately negotiated agricultural land within the notified villages. A collector's non-agricultural (NA) conversion order does not by itself equal layout approval, and buying a basic village-council (Gram Panchayat) subdivision inside an expanding urban boundary can leave a buyer with an illegal, unapproved parcel that is ineligible for standard bank loans.
• Legal requirement for any plotted layout: if a plot is non-agricultural and part of a developed layout with roads, drainage, water or electricity, RERA registration is mandatory, and a developer cannot legally advertise, market or sell such a project without a RERA registration number. Sale of plots without RERA registration where required is illegal and voidable.
• Relatively more settled: land inside the six villages that already have CIDCO/state-sanctioned development plans under the overlapping NAINA framework — Karnala (Tara), Barapada, Dighati, Sai, Kasarbhat and Dolghar, where plot transactions currently carry the cleanest title and zoning certainty available in the region — though this is still short of a fully released, RERA-registered plot product.

How land and plots are expected to be released

The New Town is being planned by MMRDA primarily on the framework of CIDCO's Navi Mumbai development model. Under the finalised policy, land will be developed and a portion returned to original landowners — an approach aimed at easing acquisition challenges while accelerating implementation. The cost of land acquisition, compensation and infrastructure development is intended to be recovered from industry allottees in phases, with an additional establishment charge levied by the authority, overseen by a high-level committee constituted to fast-track implementation.

For individual landowners, the state resolution offers multiple compensation options: monetary compensation under the Maharashtra Regional Planning and Town Planning Act, 1966, determined through mutual agreement, or participation in a land-return model. MMRDA plans to implement the CIDCO funding model, which offers developed land as compensation for land acquisition, rather than direct monetary payments. For landowners unwilling to participate, the state has retained provisions for compulsory acquisition through the district collector under the Maharashtra Regional and Town Planning Act, 1966.

This mirrors the precedent set next door in NAINA, where a similar land-return ratio was contested: CIDCO decided to keep 60 per cent of NAINA land with itself while giving back 40 per cent to farmers, a split that opposition politicians called unjustified. MMRDA expects to generate around ₹11,000 crore in revenue through land monetisation for funding capital-intensive infrastructure projects.

Comparable precedent: what happened to land values in Navi Mumbai and NAINA

Third Mumbai's closest and most direct precedent is CIDCO's own Navi Mumbai project, plus the overlapping NAINA zone, both run on the same statutory and institutional template.

Navi Mumbai (CIDCO), long-run values: property values increased from ₹4,500 per square foot in 2010 to ₹7,500 per square foot in 2020, reaching ₹10,810 per square foot in 2024. Recent CIDCO land auctions have set records: four adjoining CIDCO tender plots in Nerul Sector 28 were acquired at ₹7.65 lakh per square metre on 30 July 2024 — the highest land acquisition cost in the satellite city's five-decade history — in a deal worth ₹1,495 crore. In November 2025, CIDCO sold a 41,994 sq.m plot in Kharghar Sector 23 for ₹2,125 crore, at ₹5,06,001 per sq.m, the highest bid ever received in CIDCO's 55-year history.

NAINA (the overlapping precedent zone), timeline risk: CIDCO was designated Special Planning Authority for NAINA by notification on 10 January 2013, and landowners were initially required to pay betterment charges of up to 50% of the appreciated land value. That single charge froze the market: NAINA was declared in 2013, but CIDCO had yet to implement significant infrastructure in the area more than a decade later. The state briefly intervened — the Maharashtra government decided to suspend the betterment charges being recovered from farmers in the NAINA project in March 2022 — before a permanent fix: CIDCO cut the NAINA Betterment Charge from 50% to 0.05%, a 99.9% reduction, ratified by the state cabinet. Only after that cut did movement resume: for the first time in 12 years, CIDCO successfully finalised tenders over ₹6,000 crore for infrastructure development, appointing contractors to begin work on roads, drainage, electricity and water supply in the NAINA region.

The lesson from this precedent: large headline value gains materialised in Navi Mumbai, but only across five decades of actual trunk-infrastructure build-out, and a single unresolved policy variable (the betterment charge) was enough to stall an adjacent, similarly-notified zone for more than ten years regardless of the original announcement date.

Key risks

• Title and legality of individual land deals: buying basic village-council layouts inside an expanding urban boundary can leave a buyer with an illegal, unapproved parcel ineligible for standard bank loans, and selling plotted layouts without required RERA registration is illegal.
• Compulsory acquisition for non-consenting owners: the state has retained provisions for compulsory acquisition through the district collector under the Maharashtra Regional and Town Planning Act, 1966, which affects negotiating leverage and eventual land-return ratios for holdouts.
• Policy volatility on core economics: the NAINA betterment charge — the single biggest variable determining landowner returns — was set at 50% in 2013, suspended in March 2022, and only cut to 0.05% around 2025; a comparable policy lever in KSC New Town could similarly be revised after initial notification.
• Jurisdictional handover risk: planning functions previously handled by CIDCO for parts of this area, including NAINA and Khopta New Town villages, are being withdrawn in favour of MMRDA, creating a transition period in which regulatory responsibility and existing approvals need to be reconciled.
• Unresolved landowner disputes: the CIDCO-style 60:40 land-sharing policy has been publicly called unjustified by opposition politicians, and some political representatives have demanded the complete removal of betterment charges and raised concerns over the lack of clarity on how included villages will be developed.
• Timeline slippage precedent: NAINA was declared in 2013 but saw no significant infrastructure implementation for over a decade, and KSC New Town's own public acquisition notification was still pending as of the April 2026 consent drive.

Signals to watch

• Whether MMRDA issues the formal statutory public notification of land acquisition following the consent drive — a public notification regarding land acquisition was expected to be issued shortly as of April 2026.
• The consent response rate across the 124 notified villages, and whether compulsory acquisition is invoked for hold-out parcels.
• Whether the August 2026 master plan finalisation is delivered on schedule, and what zoning/FSI it sets for specific villages.
• Whether development plans are sanctioned for villages beyond the initial six — Karnala (Tara), Barapada, Dighati, Sai, Kasarbhat and Dolghar — inside the overlapping NAINA/KSC area.
• MahaRERA registration status of any layout marketed as being inside the KSC or NAINA boundary — verifiable on the official MahaRERA portal before any transaction.
• Execution pace of the ₹6,000-crore-plus CIDCO infrastructure tenders and MMRDA's ₹4,000 crore FY2026-27 allocation for KSC New Town.
• Whether the betterment-charge and 60:40 land-return terms remain stable or are revised again, given their documented history of change in the adjacent NAINA zone.
