How rent vs. buy is compared
Buying costs more than the mortgage payment. You also pay closing costs, property tax, insurance and upkeep, and about 6% in fees when you sell. Renting costs only rent, but rent rises each year and you build no equity.
To compare fairly, the calculator assumes the renter invests the down payment and closing costs. Each month, whoever has the cheaper housing invests the difference. At the end, the buyer's wealth is home value minus selling costs and the remaining loan, plus their savings. The renter's wealth is their portfolio.
What decides it
- Time. Buying and selling costs take years to earn back. Stays under five years usually favor renting.
- Price-to-rent ratio. When homes cost more than about 20 years of rent, renting often wins.
- Appreciation vs. investment return. Small changes here move the result a lot, so try a few.
