A growing number of homebuyers in Mumbai and Pune are choosing a less obvious path to a larger home: buying into an ageing housing society just before it goes into redevelopment.
How the Math Works for One Buyer
Take a Pune buyer with a budget of Rs 1 crore, struggling to find a spacious 2 BHK in his preferred locality. A ready 750 sq. ft. flat there runs close to Rs 1.40 crore, well outside his range. Instead, he found a 500 sq. ft. 1 BHK with a 200 sq. ft. balcony for Rs 92 lakh, in a society that has already signed a development agreement and is set for redevelopment next year. Once redeveloped, that flat becomes a 745 sq. ft. 2 BHK, and he plans to buy another 200 sq. ft. from the developer at the prevailing rate, ending up with close to 1,000 sq. ft. across 3 BHK, for a total outlay of roughly Rs 1.2 crore. Compare that to a ready-to-move 590 sq. ft. 2 BHK he'd found for Rs 95 lakh, which he felt would be too small for a family of four in the long run.
The catch is time. Possession of the redeveloped home is still three to five years out, and once residents vacate, the buyer typically covers rent on a temporary place using the monthly rental compensation the developer pays during construction.
What Developers Themselves Say to Watch For
Property professionals describe this as a genuinely sound strategy in land-constrained cities, but not a risk-free one. Anuj Mehta, Director at Dhuleva Group, said large-scale redevelopment projects in some of Mumbai's mature micro-markets have delivered returns of 20 to 40% over a project's life cycle, driven by improved infrastructure and building quality, but cautioned that buyers need to check the builder's financial strength, approval status, and the redevelopment agreement itself before deciding, not just the purchase price.
Ram Raheja, Managing Director of S Raheja Realty, pointed to two risks specifically worth scrutinising: the realistic timeline, since these projects hinge on regulatory approvals and adequate funding, and the society's own paperwork, including title, members' consent, and the development agreement. In his view, internal disputes within a housing society are often the biggest hidden risk, and the hardest to resolve once they surface.
The Market Is Genuinely Accelerating
The numbers back up the momentum. Knight Frank India recorded 229 redevelopment agreements signed across Mumbai in 2025, up 16% from 196 in 2024. That pace has continued into 2026, with close to 70 agreements signed in just the first 74 days of the year. Between January 2020 and mid-March 2026, Mumbai has seen 1,094 redevelopment agreements signed in total, unlocking an estimated 432 acres of land for redevelopment across the city.
What This Means for Buyers Weighing This Route
The pattern worth noting here is that the reward genuinely tracks the diligence. Buyers who verify the developer's execution history and the society's paperwork before signing tend to be the ones who actually see the 20-40% uplift; those who skip that step are the ones most likely to be waiting years past the promised date. As real estate advisors and consultants, this is exactly the kind of decision Hommea would want a client walking into with eyes open, checking the development agreement, the builder's track record and the society's consent status before committing, rather than being drawn in purely by the prospect of a bigger home later.
