Buying a 2 BHK in Worli is rarely an impulse purchase. It is a decision that touches financing, family planning, school admissions, commute decisions and, in many cases, the rest of your career. The good news is that the process — once you break it down into components — is very learnable. Below is the practical playbook we use with first-time buyers.
Carpet area, built-up area, super built-up area
Under the Real Estate (Regulation and Development) Act, what matters legally is RERA carpet area— the actual usable floor space inside your apartment. A “584 sq. ft. 2 BHK” under RERA is genuinely 584 sq. ft. of inside- the-flat space, not a marketing-inflated number. Older brochures may still quote built-up or super built-up areas; ignore them for decision-making, and ask the developer for the RERA-disclosed number.
For Cornerstone Worli, the published RERA carpet ranges are 581 to 586 sq. ft. for the standard 2 BHK on floors 4–35, and 607 to 659 sq. ft. for the premium 2 BHK on floors 36–40. The four-bedroom Jodi residences combine two adjacent flats into 1,166–1,325 sq. ft. of carpet area. These are the numbers you will see on the agreement and what your bank will lend against.
The MahaRERA registration check
Every project sold to the public in Maharashtra must be registered with the Maharashtra Real Estate Regulatory Authority (MahaRERA). The registration number tells you that the project has been disclosed publicly — floor plans, carpet areas, possession dates, common amenities, and any project-level litigation are all on file at maharera.maharashtra.gov.in.
Cornerstone’s MahaRERA registration is P51900005370. You should always verify the registration of any project against the public RERA portal before paying a token amount. The portal will also tell you the promoter, completion timelines and any complaints filed.
Loan, downpayment and the cost stack
For a 2 BHK in Worli, the typical purchase has five components:
- Agreement value — the price of the apartment.
- Stamp duty & registration — in Maharashtra this is approximately 6% of agreement value (combined). Some categories (women buyers, first-time, certain dates) get concessions.
- GST — 5% on under-construction property; ready-to-move (with Occupation Certificate) is GST-exempt for the buyer.
- Society and corpus charges — one-time fees the housing society collects.
- Maintenance deposit — a one-time advance, typically equal to 12 months’ maintenance.
On the loan side, a typical home loan covers 80–85% of the agreement value. The downpayment is the remaining 15–20%, plus all the costs above (which the loan does not cover). Walk into the buying decision having priced this out fully — a lot of buyers underestimate the “everything else” stack.
Banks and HFCs
Most major Indian banks (HDFC, SBI, ICICI, Axis, Kotak) and housing finance companies (LIC HFL, Bajaj Housing) lend on MahaRERA-registered projects. Your developer’s sales team will usually know which lenders have already approved the project for loan disbursement — that approval typically means faster sanction for you. Compare on three things: the rate, the processing fee, and the prepayment terms.
What to look at on a viewing
For a ready-to-move building like Cornerstone, viewings tell you a great deal. Beyond the obvious (light, view, finishes), here is what we tell first-time buyers to check:
- Cross ventilation— can you open windows on two sides? In Mumbai, this matters more than air-conditioning.
- Floor plate orientation— which way does the master bedroom face? West-facing afternoon sun in Mumbai is harsh; east-facing wakes you with the rising sun.
- Common-area finish quality— lobby, corridors, lifts. A well-maintained common area is the single best predictor of how the society will be run.
- Lift to apartment ratio— for a 40-storey building like Cornerstone, four flats per floor with multiple lifts is comfortable; ten flats per floor with two lifts is not.
- Parking— how is your car retrieved? At Cornerstone, a mechanised car-lift system delivers vehicles to the floor; for ground-level stack parking elsewhere, ask about wait times during peak hours.
- Refuge and fire safety— refuge floors should be marked, accessible and unobstructed. This is a legal requirement and a good indicator of how the developer takes safety.
The agreement and registration
Once you reserve a residence with a token amount, you sign an Agreement for Sale. This is the document that gets registered at the sub-registrar’s office and is your title chain. Read it carefully — especially the clauses on possession, default interest, society formation, and parking allotment. Most developers have a standard format that they have used hundreds of times; reasonable changes can usually be negotiated, but expect the structure to be fixed.
What to ask the sales team
A short list of the questions we recommend to first-time buyers:
- RERA carpet area and total saleable area — in writing.
- Floor and unit number reservation policy — how long is your hold?
- Construction-linked or possession-linked payment plan?
- What is included in the apartment (flooring, fittings, kitchen platform, modular wardrobes)?
- Parking allotment — how many slots, and what type?
- Maintenance charges — current per-square-foot rate, expected society formation date.
- Any pending Occupation Certificate floors — Cornerstone’s OC is in part received; ask for the certificate copy on the floor you are buying.
Final thought
The Worli market is unusually transparent for an Indian residential market — carpet areas are well-disclosed, MahaRERA disclosures are detailed, and most projects are run by established developers with public reputations to protect. The buyer’s job is to do the basic work: verify RERA, read the agreement, view the actual flat (not just the show flat), and price the full cost stack including stamp duty and society deposits.
