How to Choose the Right Property in Mumbai (Without Getting Misled)
A practical, no-spin guide for buyers navigating Mumbai's property market with a RERA checklist, red flags to watch, and a framework that actually works.

Buying a home in Mumbai is not complicated because there are too few options. It's complicated because there are too many — and most of them are presented in a way designed to make you act fast rather than think clearly.
Brochures show sunny render images of lobbies. Salespeople quote "base price" and skip the rest. Every project claims to be "strategically located" and "ready for possession soon."
Here's what actually helps: a clear checklist of things to verify, a short list of red flags to walk away from, and an honest explanation of the one database that tells you more about a developer than any sales pitch can.
Step 1: Verify the project on MahaRERA — before anything else
The Maharashtra Real Estate Regulatory Authority (MahaRERA) maintains a public register of all real estate projects in the state. Every legitimate developer selling in Maharashtra must be registered here.
How to check:
Click on "Registered Projects"
Search by project name or developer name
Look at: registration number, registered carpet area, declared possession date, and — critically — complaint history
What to look for on the MahaRERA page:
Field | What it tells you |
|---|---|
Project registration date | How long it's been active |
Declared possession date | What the developer officially committed to |
Form 4 (architect certificate) | Construction progress at time of filing |
Complaints filed | How many buyers have escalated issues |
Quarterly progress reports | Whether the developer actually updates them |
A developer who hasn't updated quarterly reports for 6+ months is a warning sign. A project with 20+ complaints deserves serious scrutiny before you book.
If a sales executive says "we're in the process of getting RERA registration" — walk away. No registration means no legal protection for your money.
Step 2: Understand the actual price — not the advertised one
The number in the ad is the base price on carpet area. That is not what you'll pay.
Before shortlisting any project, ask for the complete cost sheet in writing. It should include:
Base price (and which area it's calculated on — carpet, built-up, or super built-up)
Stamp duty (6% for men, 5% for women in Maharashtra as of May 2026)
Metro cess (1%, applicable in Mumbai)
GST (5%, only for under-construction properties)
Parking charges (separately quoted in most projects)
Floor rise charges (if applicable)
Advance maintenance deposit
Clubhouse/amenity charges
Legal and documentation charges
If a developer is reluctant to give you a written cost sheet, that reluctance is itself important information.
The real number is typically 12–22% higher than the advertised base price. On a ₹1.5 Cr flat, that's ₹18–33 lakh more. Build this into your budget before you fall in love with a project.
Step 3: Evaluate the builder — not just the project
The building you buy is only as reliable as the developer who builds it. Flashy renders and a showroom flat mean nothing if the developer has a history of delays or quality issues.
Three things to research:
Completed projects: Find 2–3 projects the same developer delivered 3–5 years ago. Visit if you can. Talk to residents. Look for visible quality in the common areas, the lift lobby, the finish on the facade. These are honest signals.
Possession track record: On MahaRERA, you can compare the declared possession date with actual completion dates on past projects. A developer who consistently delivers 12–18 months late will likely do the same with your project.
Buyer feedback: Search for the project name + "reviews" or "possession delayed" on Google and housing forums. Unhappy buyers are vocal. If there's consistent feedback about poor after-sales service, water seepage, or ignored complaints — factor that in.
The credibility checklist:
[ ] Developer has at least 2–3 delivered projects you can physically visit
[ ] Past projects were delivered within 12 months of declared date
[ ] RERA page shows no pattern of serious complaints
[ ] Developer responds to buyer queries before booking (test this)
[ ] Financial strength: project is linked to a reputed bank loan (reduces stalling risk)
Step 4: Evaluate location for your actual life — not the brochure map
Every project claims to be "5 minutes from the highway" or "close to the metro." These statements are technically true under specific conditions and completely misleading under real ones.
What to actually check:
Commute during real hours. Drive or take public transport from the project to your office at 9am on a weekday. Not Google Maps' estimate — the actual commute. A 7 km distance in Thane or Mira Road can take 45 minutes on a bad day.
Social infrastructure. Walk a 500-metre radius. Are there functional grocery stores, a pharmacy, a decent school within 2 km, and a hospital within 5 km? These things matter more day-to-day than the project's swimming pool.
Flood and waterlogging history. Ask residents in the area, not the developer's sales team. Several pockets in Mumbai — parts of Kurla, Sion, Vikhroli, Dahisar — have significant waterlogging in heavy monsoons. This affects both liveability and resale value.
Future infrastructure — verified, not promised. Check the MMRDA and MCGM public records for approved metro lines, road expansions, and development plans. Don't rely on what the salesperson says is "coming soon." A metro station that's "announced" and one that has active construction are very different things.
Step 5: Understand what you're actually buying — the carpet area rule
Under RERA, developers are now required to quote prices on carpet area — the actual usable floor space inside your flat, excluding walls. But the terminology still causes confusion.
Term | What it means |
|---|---|
Carpet area | Usable floor area inside the flat (walls excluded) |
Built-up area | Carpet area + thickness of internal and external walls |
Super built-up area | Built-up area + your share of common areas (lobbies, lifts, stairs) |
Super built-up area is typically 30–40% larger than carpet area. A flat quoted as "900 sq ft" in a pre-RERA listing might have only 620–650 sq ft of actual carpet area.
Always ask for the RERA-registered carpet area. This is the only number that tells you how much space you'll actually live in.
Step 6: Understand under-construction vs ready-to-move
This decision has significant financial and practical consequences:
Factor | Under-construction | Ready-to-move |
|---|---|---|
Price | Generally lower | 5–15% premium |
GST | 5% of base price | No GST |
Possession risk | Delays possible | Immediate |
Customisation | Some possible | Fixed as-is |
Loan disbursement | In tranches (EMI + rent burden) | Full amount at once |
What you see | Renders and sample flats | Actual flat |
For buyers currently paying rent, a delayed under-construction flat means carrying both EMI on a home loan and rental expenses — sometimes for 2–3 years. Calculate this carefully.
Red flags — when to walk away
Developer cannot show you their MahaRERA registration number immediately
No written cost sheet provided before booking
Pressure to pay a token amount "today only, price goes up tomorrow"
Sample flat looks significantly different from the actual unit you're being offered
Possession date is vague ("approximately Q3 2027") rather than RERA-registered
No bank loan tie-up with a recognised lender (suggests lenders have scrutinised and declined)
Broker or salesperson discourages you from visiting completed projects by the same developer
A pre-visit checklist for every site visit
Before you go:
[ ] Look up the project on MahaRERA
[ ] Note the RERA-registered carpet area and possession date
[ ] Check if there are active complaints
During the visit:
[ ] Ask for the full cost sheet in writing
[ ] Request details on floor rise charges and parking
[ ] Ask which floor and unit specifically you'll be offered
[ ] Check the quality of the sample flat's common areas (lobby, lifts, corridors)
[ ] Ask what bank loans are pre-approved for the project
After the visit:
[ ] Drive the commute to your workplace at rush hour
[ ] Look up reviews online for the developer's past projects
[ ] Compare with at least one other project in the same micro-market
Final thought
The Mumbai property market has plenty of good projects and plenty of questionable ones. The difference is rarely obvious from a brochure or a showroom visit. It becomes obvious when you ask the right questions, check the public records, and give yourself enough time to compare properly.
Rushing a ₹1.5 Cr decision because a salesperson created urgency is the most common — and most avoidable — mistake buyers make.
Take your time. The right flat will still be there.
