Buying a Flat or Apartment in Mumbai? — Legal & Financial Guide

Introduction

So, have you decided to buy your own home? Is it your first home? Or are you tired of renting apartments? Or you want to turn your hard earned savings into something concrete? It's not about finding the right flat if you are looking in places like Vasai, Virar, Naigaon or Nalasopara and you already know it. The list goes on starting from paperwork, bank stuff, taxes, builder jargon…etc.

We are not trying to be salesy and present a sugar-coated property pitch. But here’s a few points that you should know before you sign anything.

1. The most important legal documents to check before buying a house in Mumbai:

No matter how good the offer seems or how nice the builder’s brochure looks, there are a few non-negotiables without which do not proceed without verifying these documents:

• RERA Certificate is essential. Every under-construction property must be registered on MahaRERA. You can check the certificate by - typing in the builder’s name, check if the project is listed, and cross-check possession dates, land approvals, and layout plans. If this is not listed? SImply look for another home.
• Title Deed is for every region but areas like Vasai, Virar, and Nalasopara, it is very common for land conversion from agricultural to residential hence always verify the land title first. Your builder should own the land and not just be “in talks” or “under process” in buying the land.
• OC and CC (Occupancy and Completion Certificates) plays a very important role if there is no OC with your builder then your flat is technically illegal. BMC or the local authority can deny water, electricity, or even demolish the construction if there is no OC and CC. Always ask for these before taking possession of the flat.
• Encumbrance Certificate: This certificate shows that the property has no legal dues, mortgages, or disputes. Think of it as your protection against fraud.

2. How much down payment is needed to buy a flat in Vasai or Virar?

Let’s say you’re looking at a 1 BHK flat priced around ₹30–35 lakhs (a typical rate in Vasai-Virar). Here’s what you’ll need upfront:

• Down Payment of ₹6–8 lakhs (that sums upto approx. 20–25% of the flat’s amount)
• Stamp Duty and Registration is around ₹1.8 lakhs
• Other Costs including brokerage, society charges, legal fees that adds up to approx ₹50,000–₹1 lakh

Hence, you’re looking at ₹8–10 lakhs minimum to book the flat.

Home Loan Tip: Your credit score above 750. You can check EMI calculators (SBI, ICICI, HDFC) to figure out how much loan you’ll get based on your income. Don’t blindly rely on agents as you can know your eligibility yourself as well.

3. Which is better for home buyers among Vasai, Virar, Borivali, or Nalasopara?

Each suburb offers its own pros and cons and your decision depends on what matters more for you from connectivity, budget, peace, or long-term returns point of view.

Vasai and Virar are developing so fast that if you want long term benefits it is the best option today. Mumbai Suburbans are good for returns but the entry cost is very high and the market is fully saturated. For Nalasopara, affordability is there but it is best for rental income or short term stays.

4. Is RERA registration compulsory before buying a property in Mumbai suburban?

Every project that is under construction must be registered on MahaRERA. It ensures:

• Builder owns the land
• Layouts and timelines are approved
• Possession dates are committed legally

If a builder says “RERA in process” or “not required for this plot” then it’s a red flag.

How to check:

• Go to maharera.mahaonline.gov.in
• Search by builder name or location
• Download the registration PDF and check all details

What’s the checklist for buying under-construction vs ready-to-move flats in Mumbai?

Under-Construction Flats:

• Lower cost
• More risk
• More unit choices
• GST (5%) + Pre-EMI burden

Ready-to-Move Flats:

• No GST
• Immediate possession
• Higher price
• Fewer inventory options

Checklist for Under-Construction Flats and Ready-to-Move Flats:

• Clear land title
• Approved floor plan
• OC + CC (for ready flats)
• RERA registration
• Breakdown of charges: PLC, GST, parking, etc.

6. What taxes and charges do I need to pay while buying a home in Borivali or Nalasopara?

Stamp Duty in Maharashtra (2025):

• 5% for male buyers
• 4% for female buyers

Registration Fee:

• ₹30,000 flat for properties above ₹30 lakhs

Additional Charges:

• Parking (₹2–4 lakhs)
• Floor rise charges (₹50–100/sq.ft.)
• Society formation fund
• Maintenance deposit (₹25,000+)
• GST (for under-construction): 5%

These costs add up hence always ask for an “all inclusive” breakup in writing.

7. What’s the ideal time to buy a property in Mumbai? Any upcoming projects to watch?

There’s no perfect time. But there is a smart time that is during pre-launch or under-construction phase, when builders offer:

• Discounts
• Waived registration/stamp duty
• Free amenities or upgrades
• Easy payment plans
