Rent or buy in Bengaluru: a decision framework

Key takeaways

• Comparing EMI with rent is misleading; compare the full yearly cost of owning with the full yearly cost of renting.
• Owning costs include loan interest, the return you give up on your down payment, maintenance, tax, repairs and buying and selling costs.
• The longer you are sure you will stay, the more buying makes sense, because one-time costs are spread over more years.
• Stress-test the decision for flat prices, higher interest rates and an unplanned move before you commit.
• Security, school continuity and control over your home matter too; give them weight, but do it knowingly.

Start with stability, not with the EMI

Before any calculation, answer three questions honestly. How sure are you that you will live in this part of Bengaluru for the next seven to ten years? How stable is your household income? And after paying the down payment and purchase costs, will you still have an emergency fund of several months' expenses?

If any answer is uncertain, renting keeps your options open. Bengaluru's job clusters are far apart, and a change of office from one side of the city to the other can turn a good purchase into a two-hour daily commute. Selling a home takes time and money, so buying works best when you will not be forced to sell at a bad moment.

If all three answers are strong, the financial comparison below becomes meaningful.

What does owning really cost each year?

An EMI (equated monthly instalment) has two parts: interest, which is a cost, and principal repayment, which is a form of saving because it builds your ownership. So the true yearly cost of owning is not your EMI. It is the sum of these items.

• Loan interest paid during the year.
• Opportunity cost: the return your down payment and purchase costs could have earned if invested elsewhere at a reasonable, safe rate.
• Maintenance charges and property tax.
• Repairs and wear: buildings age, and you will eventually repaint, waterproof, rewire and replace fittings.
• Home insurance, if you take it.
• One-time costs spread over your holding period: stamp duty, registration, legal fees, interiors, and the brokerage and other costs of selling later.

What does renting really cost?

Renting has its own costs beyond the monthly rent. Rents usually rise every year or at renewal. Bengaluru landlords often ask for a security deposit of several months' rent, which is money you cannot invest elsewhere. Moving every few years means broker fees, packers, painting deductions and the time and stress of searching.

Add these up as a yearly figure. Then compare it with the yearly cost of owning a similar home in a similar location. Make sure you are comparing like with like: the same size, building quality and commute. Renting a 2BHK near your office and buying a 3BHK far away is two different decisions.

A step-by-step method you can run in a spreadsheet

This method does not need precise forecasts. It needs honest inputs and a few scenarios. Use your own numbers, and change one assumption at a time to see what really drives the answer.

• Step 1: Work out the all-in purchase cost, including charges, taxes, stamp duty, registration and interiors.
• Step 2: Decide your down payment and loan amount, and get the current interest rate from your lender.
• Step 3: Calculate the yearly cost of owning for each year: interest, opportunity cost on your own money, maintenance, tax, repairs and insurance.
• Step 4: Calculate the yearly cost of renting a comparable home, with a realistic annual increase.
• Step 5: In the renting case, assume you invest the down payment and any monthly surplus each year.
• Step 6: Pick a holding period, such as seven or ten years, and estimate the home's sale value at the end under several price scenarios, minus selling costs and any outstanding loan.
• Step 7: Compare your net worth at the end of the period in each case: home equity if you buy, invested savings if you rent.

A quick sense check: gross rental yield

Gross rental yield is the annual rent a home would earn, divided by its all-in purchase cost. It tells you how much rent the property 'pays' compared with its price.

Here is a hypothetical example, not a market figure. If a flat costs ₹1.2 crore all-in and a similar flat rents for ₹35,000 a month, the annual rent is ₹4.2 lakh, and the gross yield is 3.5%.

Compare that yield with your home-loan interest rate and what your savings could safely earn. When the yield is well below both, the yearly cost of owning is usually higher than the rent, and buying pays off only if the home's value rises enough over your holding period. That can happen, but it is a bet on price growth, not a certainty. When the yield is closer to your borrowing cost, owning and renting are nearer to break-even, and non-money factors can decide.

Stress-test before you commit

A decision that only works in the best case is fragile. Run your spreadsheet again with less comfortable assumptions.

• Price scenarios: the home's value falls 10%, stays flat, or rises modestly over your holding period, after selling costs.
• Interest rates: your floating loan rate rises by one or two percentage points.
• Early move: you have to sell or rent out the home after three years because of a job change.
• Vacancy: if you plan to rent it out, assume some months empty each year, plus repairs between tenants.
• Costs: maintenance rises faster than expected, or the building needs a major repair levy.
• Income: one earner's income stops for six months. Can you still pay the EMI?

Buying to rent out is a different question

Some people rent where they live and buy elsewhere as an investment. That can be sensible, but judge it as an investment, not as a home. The key number is net rental yield: annual rent, minus vacant months, maintenance, property tax, repairs, letting costs and tax on rental income, divided by the all-in purchase cost.

Net yield is always lower than the gross yield shown in advertisements, sometimes by a wide margin. Compare it with what the same money could earn in other investments with similar risk, and remember that a flat is harder to sell quickly than most financial assets. Use rents you can verify from comparable flats that are actually let, not the developer's projected rent or an 'assured return' promise.

Also consider the work. Finding tenants, handling repairs and dealing with deposits takes time, or a management fee if someone else does it. If you live outside the city, these costs and frictions are higher.

Beyond the numbers: when to rent and when to buy

Owning gives you security from forced moves, the freedom to change the home as you like, and continuity for children's schools and elderly parents' care. Many families value these highly, and that is a valid reason to buy even when the pure numbers are close.

Renting gives you flexibility to move closer to a new job, to try out a neighbourhood before committing, and to keep your savings liquid. It also shifts the risk of water problems, major repairs and falling prices to the landlord.

Tax rules can tilt the numbers, but benefits on home-loan interest and principal depend on which income tax regime you choose and change from time to time. Check your own position with a tax adviser rather than assuming a benefit.

Renting is usually smarter if you may change city or office location within a few years, if buying would empty your emergency fund, if the EMI would take a very large share of your income, or if you are being pushed by fear of missing out rather than a clear need.

Buying is usually reasonable if you plan to stay in one area for many years, your income is stable, you can afford the down payment and costs without stretching, the home meets your family's needs for the long term, and your stress tests still look acceptable. Waiting is also a valid decision. Not buying this year is not a failure if the numbers or your circumstances are not ready.

• Add opportunity cost on the down payment and purchase costs.
• Include maintenance, property tax, repairs and insurance.
• Estimate rent for a truly comparable home, with yearly increases.
• Count deposit, moving and broker costs for renting.
• Calculate gross rental yield and compare it with your loan rate.
• Run price, interest rate, early-move and income stress tests.
• Compare end-of-period net worth for buying and renting.
• Check home-loan tax benefits for your chosen tax regime.
