Rent or buy?
It depends on when.

Buying costs a lot to get into and out of. Stay long enough and equity wins; leave early and renting often does. See the year the lines cross for your numbers.

Compare rent and buy

How the two sides are compared

Same starting cash, different uses, compared at the end of each year.

Both sides start with the same cash. The owner turns it into a house and pays owning costs; the renter invests it, pays rent, and invests or draws on the difference each year. Compare what each has at the end.

The owner’s side

The owner pays the down payment and closing costs, then the mortgage, property tax, insurance, upkeep and dues each year. If the home were sold at the end of a year, the owner would keep its value less selling costs and the loan still owed.

The renter’s side

The renter keeps the down payment and closing costs invested. Each year, if owning would have cost more than renting, the renter invests the difference; if renting costs more, the renter draws on the savings. As a check with every rate at zero: a $100,000 home with $20,000 down against $500 rent, for one year, leaves the owner $22,667 of equity and the renter $16,667, so buying is ahead by $6,000, the year’s rent.
