There is a conversation that happens in Indian families when someone turns 30 with a stable job and no property. It involves the words settled, asset, and eventually “you are paying someone else's EMI.” It is well meant. It comes from a generation for whom buying property really was the best financial decision available. And it is worth actually checking rather than arguing about.
So let us check. Not with feelings about building equity. With the two numbers that decide the whole thing.
The two numbers
Rental yield is annual rent divided by the market price of the property. It tells you what it costs to occupy a house as a share of what it costs to own one. In Indian metros right now that sits between 2.5% and 3.5%. A ₹1.5 crore flat rents for ₹35,000 to ₹45,000 a month.
Home loan interest is what you pay to own that same house with borrowed money. Around 8.5% to 9% if your credit profile is good.
The whole argument in one sentence
When rental yield is about 3% and borrowing costs about 8.75%, renting the same house costs roughly a third of what financing it costs. That is before maintenance, property tax, society charges, stamp duty, and the down payment that stops compounding the day you hand it over.
This is not a universal truth about housing. In a lot of American and European cities rental yields run 5-7%, which makes buying far more competitive. India is its own case. Property prices ran ahead of rents for two decades and the yield got squeezed. The advice your parents give you was formed when the gap looked completely different.
The worked example
Rohit, 32, Bengaluru, wants a 3BHK in a decent part of town. Market price ₹1.6 crore. The same flat rents for ₹45,000. He has ₹35 lakhs saved. Two options, held to the same monthly outflow so the comparison is fair.
Option A - Buy
Option B - Rent and invest
Look at what Option B keeps. ₹43 lakhs of down payment and transaction costs that never left the market, and a surplus of ₹77,100 a month in year one. That surplus shrinks over time, because rent rises 5% a year while the EMI sits still. By year 15 rent is around ₹93,000 and the surplus is down to roughly ₹29,000. That crossover is real and it is the best argument the buying side has. It just arrives later than people expect.
Twenty years later
Assumptions: property appreciates 6%, which is roughly India's long-run residential average in established markets rather than the 15% stories from one boom in one micro-market. Equity compounds at 11% blended. Rent rises 5%. Both scenarios end at year 20 when the loan closes.
| At year 20 | Option A - Buy | Option B - Rent & invest |
|---|---|---|
| Property value | ₹5.13 cr | - |
| Investment portfolio | ₹0 | ₹6.9 cr |
| Total interest paid to bank | ₹1.43 cr | ₹0 |
| Total rent paid | ₹0 | ₹1.79 cr |
| Net worth from this decision | ₹5.13 cr | ₹6.9 cr |
About ₹1.8 crore, in favour of renting. And the portfolio version has a second advantage the total doesn't show. It is liquid. Rohit can sell ₹40 lakhs of it next Tuesday to fund a gap year. He cannot sell two bedrooms.
Two honest caveats. Rent is a real expense that never ends, and after year 20 the buyer's housing cost drops to maintenance while the renter keeps paying. Also, the renter has to actually invest that surplus every month for twenty years, which is exactly the thing most people fail at. Both of those get their own section below.

Why this matters more for FIRE
If you plan to work till 60, the buy-versus-rent gap is a question of ending net worth. If you plan to stop at 45 it decides whether stopping is possible. Three reasons.
An EMI does not care about your plans
Rent is adjustable. You can move to a smaller flat, a cheaper locality, a different city, in with family for a year. An EMI is a contract. It arrives at the same size whether you are employed, between jobs, or eighteen months into early retirement. Flexibility in your biggest expense line is worth a lot when your income has stopped.
Your house does not fund your retirement
A ₹5 crore flat you live in generates ₹0 of spendable income. At a 3.3% withdrawal rate, a ₹5 crore portfolio pays about ₹1.37 lakhs a month, indefinitely. One is net worth, the other is a salary. FIRE needs the second kind. This is why so many asset-rich people still cannot stop working.
The down payment is the expensive bit
₹43 lakhs pulled out of the market at 32 would have been roughly ₹3.5 crore by 52 at 11%. That transfer, from a compounding asset to a non-compounding one, costs more than all the loan interest. And it happens on day one, when it feels like saving rather than spending.

Run your FIRE number with rent as your housing cost, then run it again with an EMI. The gap in required corpus is usually bigger than people expect.
Calculate my FIRE Number →When buying wins
This is not a “never buy a house” post. There are several situations where buying is clearly better, and pretending otherwise would just be the same dogma pointed the other way.
- You are staying 15+ years. Transaction costs, 7% going in and brokerage coming out, need a long horizon to amortise. Under 7-8 years buying is almost always worse.
- Your city's rental yield is above 4.5%. Several tier-2 markets are cheaper to buy relative to rent. Compute it for your city before assuming metro numbers apply.
- You are buying mostly in cash. No loan, no interest. Then the comparison is portfolio return against property return plus the rent you are not paying, which is much closer, and peace of mind may well win it.
- You are not going to invest the difference. The big one, and I am not being funny. If ₹77,100 a month turns into lifestyle instead of SIP, the buyer wins easily. A forced-savings mechanism you follow beats an optimal one you don't.
- After you hit your number. Buying a modest home outright post-FIRE removes your largest recurring expense and shrinks the corpus you need to sustain. Completely different from buying on leverage on the way there.
- Stability you actually need. Kids in a school you can't change, parents living with you, a landlord making your life difficult. Real reasons. They don't have to be justified on a spreadsheet.
Run it for your city
Don't take Bengaluru numbers as gospel. The check takes five minutes. Find the market price of a flat you would be happy in, find what a comparable flat in the same building rents for, divide annual rent by price.
The right answer is not “never buy.” It is that this is a large financial decision and it deserves to be made on the numbers for your city, your horizon and your plan. Rather than on received wisdom formed when the numbers looked nothing like they do now. Run your city's yield first. Then decide.
The short version
- Metro rental yields of 2.5-3.5% sit well below home loan rates of 8.5-9%. Occupying a house is much cheaper than financing one.
- Like-for-like over 20 years at equal monthly outflow, renting and investing came out roughly ₹1.8 crore ahead. And the winning side can be sold on a Tuesday.
- The down payment costs more than the interest does, because it stops compounding permanently.
- For FIRE specifically: an EMI is rigid in a plan whose main asset is flexibility, and the house you live in produces no income to retire on.
- Buying still wins on long horizons, high-yield cities, cash purchases, post-FIRE downsizing, and for anyone who knows they will not invest the surplus. That last group is larger than it likes to think.
