Most people begin a home search by opening listings. That is how a decision about the next twenty years gets made by whichever flat looks nice on a Sunday. A better order is to settle whether buying fits you at all, and only then look for a property. Five questions do most of the work, and each has a number you can check.
1. Will you stay long enough?
Buying costs a lot on day one and pays back slowly. In our model on the Gulmohar Atlas median prices and rents (October 2026), buying overtook renting after 5 to 12 years across the five cities when prices rose 7% a year and a renter earned 8% on savings. With slower price growth, in our model it often did not happen within 30 years. If a transfer, a job change or a growing family could move you within five years, renting is the safer default.
The full grid is in our rent-vs-buy guide.
2. Is your income steady enough to carry a 20-year loan?
An EMI does not pause when income does. A simple test for any EMI is to take your take-home pay, cut it by a fifth, and see whether you can still cover essentials plus the EMI. If not, the loan is too big for a household whose income could dip.
3. Can you fund the whole upfront bill?
The price is not the cash you need. For a ₹1 crore flat, a worked example with 25% down, 7% stamp duty and registration, and six months of outgoings kept as a reserve comes to about ₹39.6 lakh. In this illustration the loan is ₹75 lakh and the EMI ₹67,479 at 9% over 20 years. Cheques for the builder or seller are the part people plan for; the reserve is the part they skip.
Illustration (model guides@1): ₹75 lakh loan at 9% over 20 years, so an EMI of ₹67,479; reserve is six months of ₹60,000 essentials plus that EMI. Stamp duty varies by state. Illustration — inputs are stated in the text.
RBI's housing-finance rules also cap how much of the price a lender may finance, so the down payment is never optional.
4. Does the EMI fit your income and your goals?
Lenders set their own limits on repayments as a share of income, and they differ. What matters more is what is left for living, saving and shocks. Our affordability guide turns income into three separate limits and takes the lowest.
5. Have you found a property worth checking?
Even a buyer who clears the first four needs the property to hold up. That means a price in line with the local market, a project registered with the state regulator and a clean title. Those are the checks in our guides on whether an asking price is fair and what to verify before paying a token.
The honest answer
If you clear all five, buying can be a sound decision. If you clear four, fix the fifth before you pay anyone. A lower score on any one of them is not a reason to give up, only a reason to wait or to buy something smaller.
Gulmohar's evaluation applies the same logic to a specific property: whether the price is in line with its area, whether the purchase fits your finances, and how it behaves if your income drops. You get a free snapshot first.
Common questions
How do I know if I am ready to buy a home?
Answer five questions honestly: will you stay at least five to seven years, is your income stable, can you fund the down payment, costs and a six-month reserve from savings, would the EMI still be payable if your income fell by a fifth, and have you found a specific property worth checking? If any answer is no, fix that first. The worked numbers in this guide show how to test each one.
How much cash do I need to buy a ₹1 crore flat?
In our worked example, about ₹39.6 lakh: ₹25 lakh down payment, ₹7 lakh stamp duty and registration, and a ₹7.6 lakh reserve of six months' outgoings. Stamp duty varies by state, and RBI limits how much of the price a lender may finance, so check both for your case.
Is it better to rent or buy?
It depends on how long you will stay and how fast prices rise compared with what your savings could earn. In our model on Atlas median prices and rents, buying overtook renting after 5 to 12 years when prices rose 7% a year and the renter earned 8%; with slower price growth it often did not within 30 years. Our rent-vs-buy guide shows the grid.
