How to Buy a Flat in India: Step-by-Step Guide

Buying your first flat feels big because it is. You are spending money you saved for years, and one wrong step can cost you lakhs. The good news is that the process follows a clear order. Once you know the steps, it stops feeling scary and starts feeling like a checklist you can tick off.

This guide walks you through buying a flat in India from the first budget question to the day you get the keys. It works for a new flat from a builder, a resale flat from an owner, or an under-construction project.

Quick summary of the steps

• Fix your budget and check your loan eligibility first.
• Shortlist locations and 3 to 4 flats that fit the budget.
• Check RERA, the builder track record, and all papers.
• Pay the token amount and sign the agreement.
• Get the home loan sanctioned and disbursed.
• Register the sale deed, pay stamp duty, and take possession.

Step 1: Work out your real budget

Your budget is bigger than the flat price alone. Add stamp duty, registration, GST if the flat is under construction, brokerage, parking, club charges, and interior work. These extras add roughly 8 to 15 percent on top of the base price. A flat listed at 80 lakh often costs 88 to 92 lakh by the time you move in.

Next, look at how much loan you can get. Most banks give a home loan where the EMI stays under 40 to 50 percent of your monthly income. On a salary of 1 lakh a month, that means an EMI of about 40,000 to 50,000, which supports a loan near 50 to 60 lakh over 20 years. Keep at least 20 to 25 percent of the flat price ready as down payment, since banks fund only 75 to 90 percent of the value.

Step 2: Pick the location before the flat

A good flat in a weak location ages badly. A plain flat in a strong location keeps its value. Look at daily distance to work, metro or road access, water supply, and how much new construction is still coming up nearby. In NCR, sectors along the Dwarka Expressway, Noida Expressway, and the Golf Course Extension Road have held demand well because jobs and roads sit close by.

Visit at two different times, once on a weekday morning and once at night. You learn more about traffic, parking, and safety in those two visits than from ten brochures.

Step 3: Shortlist and compare flats

Pick three or four flats in your range and compare them on the same points: carpet area, floor, facing, age of the building, maintenance charges, and the real all-in price. Do not compare on the sticker price alone. A cheaper flat with a high monthly maintenance and a bad floor can cost more over ten years than a slightly pricier one.

Step 4: Check the papers and the builder

This is the step people skip and regret. Before you pay anything serious, confirm:

• RERA registration: every ongoing project above a small size must be registered. You can look it up on your state RERA site. Our guide on how to check RERA registration shows the exact steps.
• Title and ownership: the seller must legally own the flat, with a clear chain of past sale deeds.
• Approvals: sanctioned building plan, occupancy certificate for ready flats, and no pending dues.
• Builder track record: past delivery on time, quality, and any court cases. See how to check a builder track record.

For a full list, use our property document verification checklist. If a seller rushes you past this step, treat it as a warning.

Step 5: Pay token money and sign the agreement

Once you decide, you pay a token amount to hold the flat. This is usually 1 to 2 lakh for a resale, or the booking amount set by the builder for a new flat. Get a receipt. Then comes the agreement to sell, which lists the price, payment schedule, possession date, and penalty if either side backs out. Read it fully. Ask for changes if a clause is one-sided.

Step 6: Get your home loan sanctioned

Apply to two or three banks and compare the whole offer, not the rate alone. Look at the processing fee, prepayment terms, and how fast they disburse. As of mid-2026, home loan rates sit around 7.25 to 8.7 percent depending on the bank and your credit score. A score above 750 gets you the better end. Read our note on home loan EMI and interest rates to plan the monthly outgo.

If your loan gets turned down, do not panic. Our guide on why home loans get rejected and how to fix it covers the common reasons and the way back.

Step 7: Register the flat and take possession

The final legal step is the sale deed, signed and registered at the sub-registrar office. You pay stamp duty and registration charges here, which run about 5 to 7 percent of the value in most states. See our property registration process guide for what to carry and how the day works.

After registration, take possession only against a proper handover. For a new flat, insist on the occupancy certificate and a snag list check. Get the electricity and water connections transferred to your name, and update the society records.

Common mistakes to avoid

• Booking on emotion after one site visit.
• Ignoring the all-in cost and only looking at the base price.
• Paying large sums before checking RERA and title.
• Not reading the agreement clauses on delay and penalty.
• Skipping the occupancy certificate for a ready flat.

Common questions

How much money do I need to buy a flat in India?

Plan for the down payment of 20 to 25 percent of the flat price plus 8 to 15 percent for stamp duty, registration, GST, and other charges. On a 60 lakh flat, keep about 18 to 24 lakh ready and fund the rest with a home loan.

Can I buy a flat without a home loan?

Yes, if you have the full amount. Many buyers still take a small loan because the home loan tax benefit and the safety of a bank checking the papers are worth it. You can always prepay later.

Is it safe to buy an under-construction flat?

It can be, if the project is RERA registered and the builder has a clean delivery record. Under-construction flats often cost less and offer a payment plan, but they carry delay risk. Check the builder before you commit.

What documents should I get after buying?

Keep the registered sale deed, the stamp duty and registration receipts, the occupancy certificate, the possession letter, and the latest maintenance and tax receipts. These prove clear ownership when you sell later.

How long does the whole process take?

For a ready or resale flat, four to eight weeks from booking to registration is normal, mostly waiting on the loan and paperwork. An under-construction flat depends on the possession date in the agreement.

Buying a flat is a series of small, careful steps, not one giant leap. Move in order, verify every paper, and never rush a payment. If you want help shortlisting, browse our residential listings or explore live projects to see what fits your budget.
