Model logic

Sunk cost vs. opportunity cost.

This is not only a monthly cash-flow check. It compares buyer equity with a renter portfolio that invests the down payment and any monthly savings.

Renter portfolio

The down payment and monthly savings are invested at the selected market return.

Buyer equity

Home value is compared against remaining loan balance after principal paydown.

Growth assumptions

Rent inflation, home appreciation, and market return can move the result sharply.
