Last month, I spoke to a family in Kharghar who had just bought their first home. It was a 1BHK flat in an under-construction building. On paper, it looked perfect: great pricing, builder reputation, close to a future metro station. But two weeks after booking, they found out the builder had no RERA approval, the project was stuck in legal issues, and their money was locked.
This is not an isolated case. Even in 2025, Navi Mumbaikars are still making costly real estate mistakes. Whether it’s blindly trusting marketing brochures or buying flats in overhyped areas, these errors are leading to financial stress, resale nightmares, and legal headaches. I sat with real estate experts, visited multiple projects, and pulled fresh 2025 data to list out the 5 biggest mistakes you must avoid.
Mistake #1: Trusting Brochures Over Reality
Those glossy 3D renders and catchy taglines like “sea-view luxury at budget prices” look amazing. But do they reflect reality? Most buyers still book homes after seeing brochures or watching builder videos. They don’t visit the actual site or check the location condition.
What happens: You realize later the project is surrounded by slums, has no proper road access, or has drainage problems.
Expert Tip: Always do a site visit – morning and evening. Talk to locals. Don’t fall for photorealistic ads.
Mistake #2: Blindly Relying on Upcoming Infrastructure
“Metro is coming here.” “Navi Mumbai Airport will launch soon.” “CIDCO is planning a flyover here.”
Sounds promising? Sure. But relying only on proposed infrastructure without checking timelines or execution can trap you. A major reason for hasty investments in Navi Mumbai is the hype around NMIA’s completion timeline.
What happens: You invest in a remote sector thinking metro will make it prime, but delays keep the area stagnant.
Example: Taloja Phase 2 still has weak connectivity despite years of metro construction.
Expert Tip: Invest in areas where infrastructure is underway or near completion, not just in the planning stage.
Mistake #3: Skipping RERA Checks
Even in 2025, many buyers forget the most basic rule:
Is your project RERA registered? Booking an unregistered project can result in huge legal and financial trouble. Delays, possession issues, or worse – project cancellations.
What happens: You can’t legally claim refund/compensation. The builder isn’t accountable.
Expert Tip: Always check MahaRERA.gov.in for your builder’s project ID and approval status.
“Too many first-time buyers ignore resale demand. That’s why most Ulwe flats stay vacant.” – As per my personal observation.
Mistake #4: Prioritizing Price Over Location
It’s tempting to buy where price per sq.ft. is lowest. But cheap flats in far-flung, poorly connected sectors can become resale disasters. Many buyers overlook how upcoming infrastructure like the NMIA projects will impact property value — a mistake covered in point
What happens: After 3 years, you realize no one wants to rent or buy your flat. The area lacks schools, hospitals, or roads.
Example: Sector 30, Ulwe had low prices, but buyers regret due to lack of livability.
Expert Tip: Balance price with future livability. Choose sectors near essentials like market, station, schools.
Mistake #5: Overlooking Resale & Rental Demand
A flat is an asset – but only if it has future demand. Many buyers go for small 1BHKs in crowded zones without thinking about resale.
What happens: After 5 years, you want to upgrade, but there are no buyers. Rental income is low due to high supply.
Expert Tip: Always ask: “Will I be able to sell or rent this flat easily in 3–5 years?” Choose areas with consistent rental activity.
