Practical guide

Using the Rent vs. Buy Long-Term Calculator well

Who this is for

Households deciding whether ownership still wins after opportunity cost of the down payment.

Worked example

Compare total cost of renting versus buying over 7–10 years including maintenance, HOA, and investment returns on money not used as a down payment.

Horizon changes the winner

Short stays often favor renting once transaction costs are included. Longer horizons can favor buying if you can hold through maintenance and rate cycles.

Common pitfalls

  • Assuming endless home appreciation
  • Ignoring selling costs if you may move in a few years
