Buy or Rent? The Calculation, Not the Argument

"Rent is money down the drain" and "buying is a trap" are both slogans. The actual answer depends on four numbers and one non-financial question.

The four numbers

1. The cost of buying, annually.

• Interest on the loan (the principal is not a cost — it is savings)
• Property tax
• Maintenance
• Repairs allowance
• The opportunity cost of the down payment

2. The cost of renting, annually.

• Rent
• Minus the return earned on the money you did not use as a down payment

3. Transaction costs of buying.

Stamp duty, registration, legal fees, brokerage, interiors. Substantial, paid upfront, and unrecoverable. This is what makes short stays uneconomic.

4. Expected appreciation.

The one nobody knows. It is also the number that dominates the outcome, which is why honest people disagree.

The break-even question

How many years must I stay for buying to beat renting?

Run it with a conservative appreciation assumption. Then run it with zero. If buying only wins at optimistic appreciation, the buyer is making a bet, and they should know that they are.

Because Indian residential yields are low, the monthly cost of owning typically exceeds the monthly cost of renting the same property. Owning wins through appreciation and through the forced saving of the principal — not through cash flow.

When renting is clearly right

• Stay of under three years, or a genuinely uncertain timeline
• Career requiring geographic flexibility
• The down payment would exhaust the emergency fund
• Uncertain income
• The equivalent purchase would require stretching the EMI beyond comfort
• The buyer wants an area they cannot afford to buy in — renting there is often the better life decision

When buying is clearly right

• Stay of seven years or more, confidently
• Stable income with the EMI comfortably inside it
• Down payment available without depleting reserves
• The need for security — a family, schooling, an ageing parent
• The desire to alter and control the home

The question the numbers do not answer

How much is security worth to you?

A tenant can be asked to leave. A tenant cannot renovate. A tenant moves, repeatedly, with children and schools.

For many people that has a value the spreadsheet cannot express, and it is a legitimate reason to buy even when renting is marginally cheaper. It is equally legitimate for someone else to value flexibility more.

What an agent should say

Not "buying is always better", which is self-serving and visibly so.

Say: "Here's the arithmetic for your situation. If you're staying under three years, renting is likely better and I'll tell you that. If you're staying ten, buying probably wins — and here's what it requires."

Buyers who get that answer come back, and they send people.

This is general information, not financial advice. Interest rates, tax treatment and local costs vary and change; anyone making this decision should run their own numbers with a qualified advisor.
