BuyvsRent + Invest

Buy Wins When…

• Property appreciates faster than equity returns — historically rare in the long run, but can be true in fast-growing cities.
• You stay 7+ years — transaction costs (stamp duty, registration, broker, exit costs) eat 5–10% of property value, only amortised over long stays.
• Rent ≥ 0.7% of property value per month (price-to-rent ratio < ~12). Below this threshold, renting wins almost always.
• You’re emotionally a homeowner — stability, customisation, family dynamics. Real value, just hard to put in a spreadsheet.

Rent + Invest Wins When…

• monthly payment is much higher than rent — and you actually invest the difference (most people don’t).
• Job mobility — if you might relocate within 5 years, buying is mathematically expensive.
• High-cost cities (Mumbai, San Francisco, London) — price-to-rent is often 25–40, making rent much cheaper than monthly payment.
• Equity returns > property appreciation — typical in mature markets like the (S&P 500 historically beats real estate).

The Real Killer: Discipline

Buying is forced saving — you build equity whether you want to or not. Renting only beats buying if you actually invest the down payment and the monthly monthly payment − rent gap. Most renters don’t. If you know you’ll spend the difference instead of investing it, buy.

Worked Example

Hidden Costs Most Calculators Miss

• Property tax — 0.5–2% of property value per year, varies by location.
• Maintenance / society fees — 1–2% of property value annually for upkeep.
• Insurance — 0.1–0.5% of property value.
• Closing costs on sale — broker fees, capital gains tax, legal — typically 5–10% of sale price.
• Opportunity cost of down payment — what that lump sum would have earned in the market (this calculator already includes it).
