The Rent vs Buy Equation Nobody Gets Right
'Rent is dead money.' Said by people who have never added up the stamp duty, the solicitors, the boiler, and what your deposit would have done sitting in a tracker for 25 years.
Buy vs rent: 25-year UK worked example
| Metric | Buyer | Renter | Gap |
|---|---|---|---|
| Net position | £732,000 | £574,000 | £158,000 |
| Total interest paid | £145,000 | £0 | -£145,000 |
| Total maintenance | £105,000 | £0 | -£105,000 |
| Total rent paid | N/A | £577,000 | N/A |
£350k home, £35k deposit, 4.5% mortgage vs £1,400/month rent with the difference invested at 5% real.
Key takeaways
Buying a home includes large hidden costs like stamp duty, solicitor fees, maintenance, and insurance that most people underestimate.
Renting is not throwing money away - it buys flexibility, zero maintenance liability, and frees up capital for investment.
The opportunity cost of a house deposit invested in a global index fund can be worth hundreds of thousands over 25 years.
Neither renting nor buying is always the right answer - the best choice depends on your income stability, location, and time horizon.
