Step into any property conversation in India and you will hit a wall of jargon—carpet area, FSI, stamp duty, allotment letter, ROI. Most of these terms have specific legal or financial meaning, and getting them wrong can cost you lakhs at the closing table or in the years that follow. This glossary covers the 15 terms every buyer should be able to define before signing anything.
1. Mortgage
A mortgage is a loan secured against the property itself. The bank holds the title or registers a charge until the loan is repaid. Default and the lender can take possession under the SARFAESI Act. Most home loans in India are mortgage-backed, with tenures of 15 to 30 years.
2. Off-Plan Property Investment
Buying a unit before construction is complete—often before the foundation is poured. You typically pay a booking amount, then construction-linked instalments. Off-plan is cheaper than ready inventory but carries delivery risk. Always check the developer’s RERA registration and past delivery record before committing.
Freehold Property
You own the land and structure outright with no time limit. Most residential apartments in Hyderabad and other Tier 1 markets are freehold. The opposite is leasehold, where you have rights for a fixed period (often 99 years) before reverting to the lessor.
3. Carpet Area
The actual usable floor area inside your apartment, measured wall-to-wall, excluding the thickness of the walls themselves. RERA mandates that all sale agreements quote price per carpet area, not super built-up. This is the number that should anchor every comparison.
4. Built-up Area
Carpet area plus the area occupied by the apartment’s external walls, balconies, and utility spaces. Usually 10 to 15 percent more than carpet area.
5. Super Built-Up Area
Built-up area plus your share of common spaces—lobbies, staircases, lifts, clubhouse, corridors. The loading factor (super built-up to carpet ratio) typically ranges from 1.25 to 1.40 in modern projects. A higher loading means you are paying for more shared amenities.
6. Floor Space Index (FSI)
The ratio of total built-up area to plot area, set by the local development authority. An FSI of 2.5 means a 1,000 sq m plot can support 2,500 sq m of construction. FSI rules govern density and are why some projects can build taller towers and others cannot. In Hyderabad, FSI for residential is governed by GHMC and HMDA norms.
7. Certificate of Occupancy (OC)
Issued by the local municipal authority once a project is built per approved plans and is safe to occupy. Without an OC, you cannot legally move in, get a permanent water/electricity connection, or sell the unit cleanly. Always confirm OC before taking possession.
8. Allotment Letter
The developer’s formal confirmation that a specific unit is allotted to you, typically issued after the booking amount is paid. It states the unit number, carpet area, total price, payment schedule, and possession timeline. Required for home loan disbursement.
9. Stamp Duty
A state-levied tax on the registration of the sale deed, calculated as a percentage of the property’s market value or sale value, whichever is higher. In Telangana, stamp duty for residential property is currently 4 percent, plus 0.5 percent transfer duty and 0.5 percent registration fee—roughly 5 percent of the sale value, payable at registration. Budget for it; it is not part of the loan.
10. Registration Fee
The state charge for officially recording the sale in the sub-registrar’s office. In Telangana this is 0.5 percent of the property value. Without registration, your ownership is not legally enforceable.
11. Stilt Parking
An open or semi-open ground-level parking floor with no walls, only structural columns. Common in Hyderabad apartments. Stilt parking is usually included in the price of the unit but not always—confirm in writing before signing.
12. Asking Price
The price the seller initially quotes. In primary-market apartment sales it is usually firm; in resale, expect 5 to 10 percent negotiation room depending on market conditions.
13. Bayana (Token Amount)
The initial sum paid to lock in a property and signal serious intent. Typically 1 to 2 percent of the sale value in resale transactions, or a fixed booking amount (often Rs. 1 to 5 lakhs) in primary sales. Backed by a written agreement; usually non-refundable if the buyer walks away without cause.
14. ROI (Return on Investment)
For real estate, ROI combines two streams: rental yield (annual rent / property value, typically 2.5 to 3.5 percent in Hyderabad’s premium pockets) and capital appreciation (year-on-year price growth). A 7 to 9 percent total ROI is considered healthy in current Indian markets.

15. EMI (Equated Monthly Instalment)
The fixed monthly payment you make to the lender for principal and interest combined. EMI depends on loan amount, interest rate, and tenure. A useful first step before any property decision: run your numbers through an EMI calculator and confirm the monthly outgo fits inside 40 to 50 percent of your take-home pay.
Frequently Asked Questions
What are the most important real estate terms buyers should know?
Carpet area vs super built-up area, RERA registration, OC, stamp duty, and EMI are the five that show up in every transaction and have direct financial consequences if misunderstood.
What should first-time buyers consider before purchasing property?
Three things in order—total cost (sale price plus stamp duty, registration, GST, brokerage, interiors), monthly affordability (EMI under 40 percent of income), and the legal trail (title chain, RERA, OC, encumbrance certificate). Anything else is secondary.
How does Auro Realty ensure transparency for buyers?
Every Auro Realty project is RERA-registered with the carpet area, possession timeline, and payment milestones disclosed upfront. Buyers receive allotment letters within stipulated timelines, and project updates are communicated regularly through the project portal.
