Buying apartments and condominiums in Mumbai: a buyer’s decision guide

Begin with the buyer and the usable apartment

Buying a Mumbai apartment means choosing both a private dwelling and a share of the risks, costs and rules of its building. The word “condominium” in an advertisement does not establish a particular legal ownership regime. Start with three written answers: who may legally buy, which exact unit and associated rights are offered, and which building obligations will follow the buyer. This guide concerns residential flats and apartment interests in Mumbai, Maharashtra—not a live inventory, price quotation or substitute for property-specific legal and engineering checks.

Make a short brief before viewing: owner-occupation or lawful letting, household size, step-free access, parking, commute at realistic peak hours, cash and financing ceiling, intended possession date and tolerance for construction delay. Check water supply, ventilation, noise, flooding or waterlogging exposure, lift capacity and fire-escape access in person. A tower view, clubhouse or reputed address is not evidence that the individual flat or its access arrangements fit the household. Compare the actual building and street, not only brochure renders.

Use a consistent area basis. Under India’s Real Estate (Regulation and Development) Act, 2016, “carpet area” is defined as net usable apartment floor area including internal partition walls, but excluding external walls, service shafts and exclusive balcony, veranda or open-terrace areas. Ask for the sanctioned plan and the contract’s carpet-area schedule; record any additional balcony, terrace or other space separately. An advertised super-built-up or saleable area, where used, is not interchangeable with statutory carpet area. Recheck fit, furniture clearances and storage against a measured floor plan.

Three purchase routes have different evidence burdens. In a lived-in resale flat, inspect actual condition, the seller’s transfer power, society or association dues and previous alterations. In a newly completed flat, inspect the actual unit and the relevant occupation/completion approvals, not simply the developer’s handover invitation. In an under-construction project, scrutinise the registered project and phase, approved plans, payment milestones, completion information and contract remedies. Do not compare the three solely on price per square foot without normalising usable area, occupancy date, amenities and exposure to unfinished common works.

Turn the viewing brief into a two-stage shortlist. Reject a candidate if buyer eligibility, intended lawful use or essential access cannot be demonstrated. For a completed flat offered for occupation, missing required occupation approvals is also a stop; an under-construction flat instead needs verified project approvals, realistic delivery disclosures and contractual remedies, not a premature occupancy certificate. Attractive finishes cannot cure these failures. For the remaining flats, compare the same fields side by side: verified carpet area; all-in acquisition cost; realistic occupation date; peak-hour journey; current maintenance dues and potential special levies; documentary parking and storage rights; building condition and expected major works; and contractual consequences of late delivery. Compare total acquisition cost per square metre of carpet area only after checking what each quotation includes, and compare yearly ownership costs separately. A lower asking price is not necessarily a saving. Mark unknowns as “unverified”, not “no problem”, and seek documents before choosing a preferred flat.

Identify the ownership structure and common obligations

Ask what legal framework actually governs the building. A Maharashtra condominium governed by the Maharashtra Apartment Ownership Act, 1970 involves a registered declaration, apartment deeds and defined interests in common areas; a co-operative housing society follows a different membership/share and transfer-document structure. Buildings may also involve leasehold land, developer conveyance or redevelopment arrangements. An estate agent’s use of “condo” or “freehold” is not legal proof. Have a local conveyancing lawyer trace the seller’s instrument, building/land tenure, underlying permissions and the body that controls common property.

Match unit number, floor, carpet area, sanctioned layout and property description across the proposed agreement, registered title or allotment documents, property records and site inspection. For resale, obtain the chain of registered transfers, relevant index/encumbrance searches, loan-release evidence where a mortgage exists, identity and authority of every seller, and relevant society documents. Check litigation, attachments, inheritance or co-owner consent issues rather than assuming a bank valuation or tax receipt proves marketable title. Where the land is leased, review remaining term and assignment, renewal and consent conditions.

Treat parking, storage, terraces, gardens and clubhouse access as separate evidence questions. Identify whether each is owned, exclusively usable, allocated by the managing body or merely an amenity that can change; check the sanctioned plan, declaration or society records and contract wording. Never infer ownership of a parking bay from a broker’s photograph or an additional payment request. Determine who maintains and insures exclusive-use areas and whether rights transfer with the flat. Common corridors, fire exits and service areas should not be privately occupied merely because someone has done so before.

Request recent maintenance bills, audited accounts or available financial statements, approved budgets, arrears statement, meeting minutes, insurance evidence and a schedule of planned repairs or redevelopment. Verify who holds reserves, which works are approved, whether major lift, façade, waterproofing, fire-system or structural expenditure is expected, and how costs are allocated. A low monthly charge can conceal deferred maintenance; a higher charge can include services absent elsewhere. Compare recurring dues and special levies on the same inclusion basis. Ask which seller debts must be settled before transfer.

Confirm intended use with the applicable declaration, bye-laws, society/association decisions, lease terms and competent authorities. Residential use does not automatically establish permission for short-term guests, business activity, subletting, pets, major partitions, balcony glazing or structural alterations. Do not transplant another country’s condominium rules. Seek written clarification for any non-standard use and treat verbal assurances as provisional. An expected rental yield is only a scenario until legal letting rights, realistic vacancy, operating expenses and tax position have been tested.

Verify the project, seller and permission to occupy

For a project within RERA’s registration scope, search the exact promoter, project number and phase on the official MahaRERA portal. Check the current registration status, declared completion dates, uploaded approvals, encumbrances, quarterly updates, complaints or orders and changes to plans. A matching marketing name is insufficient: confirm the precise wing and apartment. Registration is a disclosure and regulatory checkpoint, not a government title guarantee, construction warranty or proof that all project facilities are finished. For a genuinely exempt or older resale property, obtain an explanation of the exemption and still investigate title and approvals.

For development purchases, examine sanctioned building plans, commencement permissions, the version of the MahaRERA disclosures, building-wise occupancy certificate or competent completion evidence when relevant, draft agreement and specifications. For resale, request the actual occupancy documents available for that building and trace any changes or unauthorised works. Distinguish possession, legal permission to occupy and final conveyance: they are different steps. Ask for professional assessment where cracks, leakage, fire access or major services create engineering uncertainty; photographs and marketing brochures cannot close that gap.

Section 13 of the RERA Act restricts a promoter from taking more than 10% of the apartment cost as advance or application fee before a written, registered agreement for sale. The agreement should specify development and payment particulars, handover timing and default consequences. The rule is not a universal cap on every deposit in an ordinary private resale or a waiver of review. Before payment, confirm the counterparty, permitted account, refund triggers, conditions precedent and allocation of costs. Do not send substantial funds solely against a reservation email or unsigned draft.

Budget for the transaction, not only the asking price

Build a rupee-denominated acquisition schedule: agreed consideration; applicable Maharashtra stamp duty, registration and local charges; legal/search and inspection fees; lender valuation, processing and mortgage costs; brokerage when agreed; move-in, repairs and utility deposits; and initial society/association contributions. Confirm present rates and the applicable valuation basis with the Maharashtra Registration and Stamps authorities and the transaction professional; Mumbai sub-location, instrument, concession eligibility and buyer facts can change the outcome. No generic online percentage safely replaces a dated property-specific calculation. For cross-border funds, budget against the bank’s actual conversion rate at execution, not a headline exchange rate; include transfer and intermediary bank charges, exchange-rate movement and timing of receipt.

GST depends on transaction structure and completion/first-occupation timing. The central tax framework distinguishes construction services sold before the relevant completion/first-occupation point from qualifying completed-property sales; do not assume that a quoted “all-inclusive” price settles GST treatment. Obtain the developer’s itemised tax invoice basis and written advice for unusual structures. For ongoing ownership, separately model monthly maintenance, municipal taxes where applicable, insurance, utility costs and a reserve for exceptional repairs. A loan EMI is not the whole carrying cost.

Withholdings and reporting are buyer-specific. The Indian Income Tax Department’s Form 141 system under the Income-tax Act, 2025 includes Schedule B for applicable purchases from resident sellers and, from 1 October 2026, Schedule E for qualifying resident individual/HUF buyers purchasing from non-resident sellers. Seller residency, purchaser type, consideration and relevant dates change the TDS procedure; do not blindly apply an old Form 26QB workflow or one rate to every seller. Obtain tax review before each payment, including instalments, and preserve PAN, withholding, filing and payment records.

Determine acquisition eligibility before paying a booking amount. RBI guidance generally permits NRIs and OCIs to buy Indian residential property, excluding agricultural land, farmhouses and plantation property, with specified banking payment channels. Foreign nationals of non-Indian origin resident outside India do not have an equivalent general purchase permission; residence, inheritance, eligible NRI/OCI spouse joint purchase and country-specific restrictions may change the analysis. A tourist stay or possession of money does not create eligibility. Request FEMA-status advice, and separately assess whether eventual sale proceeds may be remitted abroad. Under RBI’s published framework, a non-NRI/OCI spouse may acquire one qualifying property jointly with an NRI/OCI spouse only on conditions including a registered marriage subsisting for at least two years, permitted banking payments and no other legal prohibition. Certain citizenships require prior RBI permission irrespective of residence, subject to the applicable OCI exception. Verify the current FEMA and non-debt-instrument rules for the individual.

Run a controlled purchase process

Use staged commitments. First: identify the unit and owner/promoter, screen eligibility, inspect building and fetch documents. Second: engage independent local title, tax and technical reviewers; compare their findings against the proposed price and repair budget. Third: agree material conditions and a payment timetable in writing before any non-refundable commitment. Fourth: have the correct instrument executed, stamped and registered as required; route payments through documented banking channels and perform seller-loan discharge/transfer checks. Fifth: receive possession evidence, meter readings, keys, original or certified records and society/association transfer acknowledgements. Remote document review or representation does not establish that identity, execution, registration and handover can all be completed entirely remotely.

Decide whether to proceed, renegotiate or stop

Proceed only if buyer eligibility, transferable rights, lawful occupation, usable space, building finances and all-in funding are verified and contractual risks are acceptable. Renegotiate if a documented repair, arrear, parking ambiguity or delivery exposure has a workable cure and an enforceable allocation. Stop or defer if title is unexplained, required approvals are absent, material facts conflict, seller authority is doubtful, payment routing is opaque or a legal-use restriction defeats your purpose. For example, a cheaper flat with unbudgeted façade work and uncertain parking may cost more and serve the household worse than a documented alternative. Revalidate time-sensitive documents immediately before signing: this is a decision framework, not a clearance of any particular property.
