Quick Answer
Before buying your first flat: fix a budget that includes 10–30% extra costs, check the project on your state RERA website, get the title and approvals verified, pay no more than 10% before a registered agreement for sale, and take possession only after the occupancy certificate is issued.
1. Comparing ad prices, not all-inclusive prices. Two "₹75 lakh" flats can differ by ₹8 lakh once charges are added.
2. Paying 20–30% on a "special offer" before the agreement. Section 13 caps it at 10% until the agreement is registered.
3. Trusting the sample flat. The agreement's specifications and carpet area are what you are buying.
4. Not reading the RERA project page. It shows the real completion date and complaints, for free.
5. Taking possession without an occupancy certificate. It can affect your loan, utilities and resale.
6. Signing the possession letter without inspecting. List every defect first; the 5-year defect rule still protects you after.
Make one folder, paper and digital, with: the booking form and every receipt, the allotment letter, the registered agreement for sale, all demand letters, the loan sanction and disbursement letters, TDS challans and Form 16B, the occupancy certificate, the possession letter, the registered sale or conveyance deed, the mutation record, and the RERA registration certificate of the project. You will need them for resale, tax, insurance and any complaint.
What should a first-time home buyer check before buying a flat?
Check that the project is registered on your state RERA website, read its RERA page (completion date, approvals, progress reports and complaints), get the land title and approvals checked, confirm the carpet area and the full price breakup, pay no more than 10% before a registered agreement for sale, and for a ready flat confirm the occupancy certificate.
How much down payment do I need for a flat in India?
At least 10% of the property value for loans up to ₹30 lakh, 20% for ₹30 lakh to ₹75 lakh, and 25% above ₹75 lakh, because RBI caps home loans at 90%, 80% and 75% of the value. On top of that, budget for stamp duty, registration, GST and other charges, which banks usually do not finance.
Is it better to buy a ready-to-move or an under-construction flat?
A ready flat with an occupancy certificate has no GST and no delay risk, and you can inspect exactly what you buy. An under-construction flat is usually cheaper and lets you pay in stages, but carries 5% GST (1% for affordable housing) and the risk of delay. RERA gives you a refund with interest under Section 18 if the builder misses the possession date.
What documents should I check before buying a flat?
The RERA registration certificate, title documents and land records, the approved building plan, the encumbrance status, the allotment letter and agreement for sale, and for a ready flat the occupancy or completion certificate. For a resale flat also check the previous sale deeds, society NOC and dues.
How long does the home buying process take?
For a ready flat, booking to registration can take three to six weeks, depending on the loan and paperwork. For an under-construction flat, the agreement is signed soon after booking, but possession comes only on the completion date shown on the RERA website, often two to four years away.
Do I need a lawyer to buy a flat?
It is strongly advisable for the title check and the agreement for sale, especially for a resale flat or a plot. The bank's legal check protects the bank, not you. A lawyer's fee is small next to the price of the flat.
What if the builder delays possession?
Under Section 18 of the RERA Act you can either withdraw and get a full refund with interest, or stay in the project and get interest for every month of delay until possession. File a complaint with your state RERA Authority under Section 31 if the builder does not pay.
