25 Real Estate Terms Every Mumbai Property Buyer Must Know in 2026

The RERA Act mandates that every residential project exceeding 500 sq m of land or having more than 8 apartments must be registered with the state RERA authority before any bookings or sales can commence. Developers must deposit 70% of project funds in a separate escrow account, ensuring money raised from buyers is actually used for that project — preventing fund diversion to other projects.

In property transactions, multiple types of NOCs are required. A builder requires NOC from the municipal authority to begin construction. A buyer needs NOC from their housing society when selling a flat. Banks require NOC from the builder before releasing a home loan. Fire department NOC and environmental NOC are required for large projects.

The OC is perhaps the most critical document when buying a ready or resale property. Without OC, a building is technically an unauthorised structure. Residents without OC cannot get legal water connections, electricity in their name, or piped gas connections. Banks may refuse home loans for properties without OC, and the property cannot be legally sold or mortgaged.

CC is obtained after construction is physically complete and inspected. It precedes the OC. While CC confirms that the building is built as designed, OC confirms it is safe to live in. Both are required for a legally compliant property. Missing CC means the building may have deviations from sanctioned plans — a serious legal risk.

An LOI is commonly used in commercial property transactions. It outlines key terms — price, payment structure, possession timeline — but is not legally binding in the same way as a full sale agreement. It serves as a negotiation anchor and is often accompanied by a token amount or booking deposit.

In real estate, an MoU is often signed between a buyer and seller to record agreed price, payment schedule, possession date, and inclusions before the formal sale deed. While MoUs can be legally binding if properly drafted, they are sometimes treated as non-binding in practice. Always have a lawyer review the MoU.

The ATS is executed before the final sale deed and is typically registered at the sub-registrar's office. Under RERA, developers must register the ATS (called an Agreement for Sale) within 30 days of receiving 10% of the property value. The registered ATS protects the buyer's interest and is evidence of the transaction.

The EMI is calculated using three variables: loan amount (principal), interest rate, and loan tenure. Higher tenure means lower EMI but higher total interest paid. The EMI formula is: EMI = P × r × (1+r)^n / ((1+r)^n – 1) where P = principal, r = monthly interest rate, n = number of months.

The BSP is not the all-in price. The final cost of a property is significantly higher than BSP × area. To BSP, developers add Preferential Location Charges (PLC), infrastructure charges, parking cost, club membership, maintenance deposit, stamp duty, registration charges, GST, and legal fees. In some projects, additional charges can add 15-25% to the BSP.

PLC varies by project and developer. A garden-view flat may carry a PLC of Rs. 50–200 per sq ft over BSP. A high floor with city view may attract Rs. 200–500 per sq ft PLC. PLC is negotiable in many projects, especially during early launch or low-demand periods. Some developers waive PLC as a promotional offer.

For residential properties in Mumbai suburbs, annual rental yield typically ranges from 2.5% to 4%. Capital appreciation in established corridors like Jogeshwari West or Goregaon has historically been 6-12% annually. Combined, a well-chosen property in Mumbai's growth corridors can deliver 8-15% total annual ROI over a 5-10 year horizon.

Stamp duty makes your property sale agreement legally valid. Without paying stamp duty and registering the document, a property transaction has no legal standing in a court of law. Registration charges are paid separately to the sub-registrar's office.

The BHK system is unique to Indian real estate. A 1 BHK typically suits individuals or couples, a 2 BHK suits small families, and a 3 BHK suits larger families. "1.5 BHK" typically means a 1 BHK with a small utility room. "Studio" means an open-plan unit without a separate bedroom wall.

Carpet Area: Net usable floor area — from wall to wall, excluding wall thickness. What you can actually use.
Built-up Area: Carpet area + thickness of inner and outer walls. About 10-15% more than carpet area.
Super Built-up Area: Built-up area + proportionate share of common areas (lobby, lift, staircase, amenities). Typically 25-40% more than carpet area.

FSI = Total Built-up Area ÷ Plot Area. An FSI of 2.5 on a 1,000 sq m plot means 2,500 sq m of built-up area is permitted. Higher FSI allows more construction — more apartments, more floors — which typically makes land more valuable. Governments increase FSI in specific zones to promote development.

In a building on 1,000 sq m of land with 10 flats of equal size, each flat owner holds UDS of 100 sq m. UDS is registered in the sale deed and is a direct indicator of land ownership. Properties with higher UDS have greater inherent land value, especially in redevelopment scenarios. When a building is redeveloped, UDS determines your entitlement in the new building.

CAM is primarily relevant in commercial properties (office spaces, retail malls) and premium residential societies. In commercial leasing, CAM can add Rs. 20–80 per sq ft per month to the base rental. In residential societies, CAM is typically called maintenance charges and is managed by the housing society committee.

In a typical CLP: 10% on booking, 10% on agreement, then payments of 10-15% at each construction milestone (plinth, slab 1, slab 2, brickwork, plastering, finishing, possession). CLP protects buyers because money flows to the developer only as construction progresses. It is considered the safest payment plan for buyers of under-construction properties.

Developers use EOI during the pre-launch phase to gauge demand before formally launching a project. An EOI amount (typically Rs. 1–5 Lakh) secures a buyer's place in the priority list and is usually fully refundable if the buyer decides not to proceed after the formal launch. EOI does not constitute a sale agreement.

EDC is common in Haryana and other states for large township developments. In Maharashtra, similar charges may appear under different names in municipal areas. EDC is paid by the developer to the government but is typically passed on to buyers as part of the total cost. EDC ensures that new developments do not burden existing municipal infrastructure.

IDC complements EDC. While EDC funds external infrastructure, IDC covers what is built within the project. Both are typically included in the developer's cost and reflected in the BSP or as separate line items in the cost sheet. Understanding both helps buyers know exactly what their money is building.

TPAs are common in tripartite agreements between builder, bank, and buyer for home loan disbursements. The bank secures its interest in the property through the TPA, which defines the responsibilities of all three parties — particularly for under-construction properties where loans are disbursed in stages.

JV projects are common in Mumbai's redevelopment landscape. A landowner or existing society with prime land may enter a JV with a reputed developer. The landowner typically receives a share of the developed flats or a revenue share, while the developer manages construction and sales. JV projects can offer good value but require careful scrutiny of the JV agreement.

DMIC spans 6 states (Uttar Pradesh, Haryana, Rajasthan, Madhya Pradesh, Gujarat, Maharashtra) and aims to develop 24 new industrial cities. In Maharashtra, the Shendra-Bidkin Industrial Area near Aurangabad (now Chhatrapati Sambhajinagar) and areas in Nashik are key DMIC nodes. DMIC's influence on real estate is primarily in industrial zones along the corridor.

TOD zones receive higher FSI (Floor Space Index) allowances than standard zones, enabling more development around transit hubs. The rationale: higher density near transit reduces car dependence, improves walkability, and makes transit infrastructure more economically viable. Globally, TOD zones consistently command 15-30% price premiums over non-TOD locations.
