FAQ

What is the opportunity cost of a down payment?

Money used for a down payment could instead be invested. The opportunity cost rate estimates what that money would have earned — typically 7% for a diversified stock portfolio. This is subtracted from buy costs.

Why might buying be more expensive in the short term?

Early mortgage payments are mostly interest, and transaction costs are high. In the first few years, total buy costs often exceed total rent costs. The break-even year shows when buying becomes cheaper.

Does home appreciation always make buying better?

Higher appreciation reduces the net cost of buying by growing your equity. But it is not guaranteed. The calculator lets you adjust appreciation rate to test pessimistic and optimistic scenarios.
