Rent or buy?
The comparison is usually rigged, and not on purpose: whichever side costs less each month has to be shown investing the difference, or it is not a comparison at all.
What makes this one fair
Both sides start with the same cash. Each month, whichever option costs less puts the difference to work at the return you set. Without that, buying looks better simply because it costs more — the money the renter did not spend has to go somewhere.
What it counts
- The deposit, and what it would have earned instead.
- The mortgage payment against the rent, with rent rising over time.
- Upkeep and tax, which are easy to leave out and are not small.
- What the property does, which you set — nobody knows it.
No tax relief of any kind is modelled, and the rules differ by country and change. Treat the answer as the arithmetic of your own assumptions, not as advice about a purchase.
