Questions fréquentes
How is the breakeven year calculated?
It is the year where the homeowner's net worth (home equity minus all ownership costs) exceeds the renter's net worth (the down payment and monthly savings invested in the market instead). Before that year, renting would have left you wealthier; after it, buying wins.
What is opportunity cost in a rent vs buy decision?
Opportunity cost is the return your down payment could have earned if invested elsewhere, such as an index fund. A $60,000 down payment growing at 7% per year would be worth about $118,000 after 10 years — the calculator credits this to the renting scenario.
Why does renting sometimes beat buying?
When home price growth is low, interest rates are high, or you move within a few years, the transaction costs and interest of buying can outweigh the equity you build. Buying usually wins with long holding periods and reasonable price appreciation.
Which costs of ownership does the comparison include?
The model includes mortgage interest and principal, purchase closing costs, property tax, insurance, maintenance, and selling costs, and compares them against rent, renter's insurance, and rent inflation over time.
