Why this kit exists

A glossy listing proves almost nothing in India.

Something on a listing felt off, the price too good, the photos too perfect, the agent too eager. Good instinct. The sub-registrar who stamps a sale deed does NOT check whether the seller actually owns the land; he checks identity and stamp duty. That's exactly how the same plot gets sold twice (SC, K. Gopi v. Sub-Registrar, 7 May 2025: 'registration is not the cause of ownership').

So the burden of proof is on you. This is the 12-minute version of what a careful lawyer would do, enough to kill a bad listing fast, or greenlight a good one for a proper legal check.

The 12-minute check (timed, do it in order)

Work top to bottom. The moment any RED LINE fails, stop, you've saved yourself weeks.

Min	Step	What you do	Red line, walk away if…
0–2	Carpet, not the headline	Ask for the CARPET area and carpet rate in writing	A '1,000 sq ft' flat with no carpet figure, nationally you pay for ~40% air
2–4	OC + RERA status	Get the RERA number and OC status; search the number on the state portal yourself	No RERA number, or a 'pre-launch' booking (illegal under RERA §3)
4–7	Title chain + CERSAI	Ask for the 30-year title chain and a CERSAI check	Seller can't produce the chain, or CERSAI shows a charge. A registered deed alone is NOT proof of ownership
7–9	GPA + land conversion	Refuse any 'GPA sale'; confirm the land is legally converted for the use sold	Sale on GPA / Agreement-to-Sell / Will (zero ownership). Unconverted land = demolition risk, no loan
9–11	Scarcity + double-sale sanity	Treat 'SOLD OUT / only 2 left' as marketing; ask if it's registration-at-purchase	High-pressure scarcity. There are ~5.77 lakh unsold flats across 7 cities, 'sold out' is usually a flip
11–12	Protect your number	Do NOT drop your phone number into the enquiry box yet	The form demands your number before showing basic facts, that's how it gets sold to 8+ brokers

Carpet vs super-built-up: the number that quietly costs you lakhs

Super-built-up = your flat + a share of lobbies, lifts, walls and 'amenities'. Carpet = the floor you can actually use. The gap is LOADING, nationally 40% in 2025 (up from 31% in 2019); Mumbai is worst at 43%. Always ask for the CARPET rate:

Sold as	Loading	Real carpet	₹10,000/sq ft headline → true carpet rate
1,000 sq ft (national avg)	40%	~600 sq ft	₹1 cr total → ~₹16,700/sq ft
1,000 sq ft (Mumbai)	43%	~570 sq ft	₹1 cr total → ~₹17,500/sq ft

Same total price, smaller real flat. Builders headline the super-built-up rate because the carpet rate looks scary. Make them put carpet area and carpet rate in the agreement.

The model flat is a stage set (measure, don't feel)

Sample flats are engineered by designers to trigger emotion, not show you what you'll get. Walk in with a tape measure:

The 'king' bed is often a 5-ft prop

So the bedroom feels huge. Measure the bed; measure the room.

Walls are thin gypsum partitions

Sometimes with no doors and glass dividers, the real flat has solid walls that eat floor space.

Ceilings are raised, the view is the best

And the fittings, fixtures and finishes on display are usually premium upgrades you will NOT get in the standard handover. Ask in writing: 'Is this the standard spec?'

The one test that beats the illusion

Measure the model flat's carpet area yourself and compare it to the carpet area in the draft agreement. If they don't match, believe the paper, not the room.

Data self-defence: keep your number out of the spam machine

The moment you enquire on a typical listing, your number can be sold to 8+ brokers. That's the business model. Your defence:

Don't enter your real number to 'unlock' a price, basic facts (carpet, RERA no., OC status) should be visible without it.
If you must give a number for a genuine site visit, use a secondary SIM / call-forwarding number you can later silence.
Never share your number, PAN, Aadhaar or salary slips just to 'check eligibility' early, those come at the loan stage, with a named bank.
Ask: 'Will my details be shared with other agents or partners?' Get the answer before you give anything.
Verify the property FIRST (the 12-minute check), enquire SECOND. Most bad listings die before you ever need to make contact.

The 'real or fake' checklist

Real listings can show you all of this on request. Fake or shady ones stall on most of it (screenshot this):

Carpet area + carpet rate, in writing
RERA registration number (and it checks out on the state portal)
OC status, affects GST too (ready/OC = 0%, under-construction = 5%)
30-year title chain provided
CERSAI clear (no hidden charge / mortgage)
NOT a GPA / ATS / Will 'sale', a proper registered conveyance
Land legally converted for the use being sold
Scarcity claims ignored until proven
Your phone number still private

If 8–9 boxes tick, take it to an independent lawyer for the full title search before any payment. If 3 or fewer tick, you already have your answer.

Not legal or tax advice

This kit is general information for buyers. Verify every figure against original documents and consult an independent property lawyer and a chartered accountant before you pay anything.

You just did, by hand, what most buyers never get told to do.

And you saw how much work it is to trust a single listing. villow removes it: listings are VERIFIED before you ever see them, real carpet area, OC and RERA status, clean title, checked up front, not left for you to chase. And your data isn't the product: no number-for-price gates, no selling your details to a crowd of brokers.
