Compare two complete situations
A rent payment and a mortgage payment are not directly interchangeable. Ownership ties up a deposit, has purchase and selling costs, and creates maintenance responsibilities. Renting can leave initial savings available to invest. A comparison should account for those differences before declaring one option cheaper.
Understand the equal-budget model
The renter starts by investing the amount the buyer uses for the deposit and buying costs. Each month, both households have the same available budget: whichever household spends less on housing invests the difference. The buyer’s final position includes the home’s value after selling costs, less the mortgage balance, plus any invested monthly savings. The renter’s position is the investment balance.
Challenge the assumptions
House-price changes, investment returns, maintenance and rent changes are user-entered scenarios. Try flat house prices, lower investment returns and a shorter stay. An assumption about future rent is not a statement about lawful rent increases. Enter investment returns after tax and fees, and remember the model leaves grants and tax reliefs out.
Add the decisions a calculator cannot price
Job stability, moving flexibility, school location and the availability of suitable homes may matter as much as the final number. Buying can be financially attractive in one scenario and unsuitable for your circumstances. Use the table to understand how your expected length of stay changes the comparison, then assess real properties and finance options.
