A city name does not determine whether renting or buying produces the better outcome. The answer changes with the specific property, rent, financing, horizon, transaction costs, and user-selected future assumptions.
Quick answer
Compare the same home and time horizon using:
- current rent and deposit
- purchase price and upfront cash
- stamp duty, registration, maintenance, and other ownership costs
- loan amount, rate, tenure, and rate-reset sensitivity
- user-selected property-appreciation assumption
- user-selected rent-growth assumption
- user-selected investment-return assumption for cash not used to buy
- taxes and transaction costs where applicable
None of the future rates is a Bengaluru forecast.
Use observed data carefully
NHB RESIDEX is an official housing-price index source. An index can provide historical context, but a city index does not predict a specific property's future value or justify one fixed appreciation rate. Locality, building, legal status, maintenance, supply, and transaction price can differ materially.
Compare cash flows before wealth estimates
On the buying side, include upfront cash, EMI, ownership costs, and estimated sale costs. On the renting side, include rent, rent changes, moving costs where relevant, and the actual amount available to invest. Do not assume the renter always invests the difference or that an investment earns the modeled rate.
Illustrative scenario
Illustrative scenario: enter one Bengaluru property price and comparable rent, then test low, middle, and high user-selected assumptions for appreciation, rent growth, and investment return over the same horizon. The result may switch as assumptions change; that sensitivity is the useful output.
Non-financial factors
Tenure security, flexibility, control over the home, maintenance responsibility, commute, family needs, and expected length of stay matter even when two modeled financial outcomes are close.
Common mistakes
- Presenting historical appreciation as a future forecast.
- Choosing a winner from one return assumption.
- Comparing unlike homes or different horizons.
- Omitting transaction costs or assuming every monthly difference is invested.
What to do next
Use the Rent vs Buy Calculator with your actual property, rent, financing, and explicit scenario assumptions. Review several cases instead of using one city-wide conclusion.
