Renting vs. Buying a House: What Actually Determines the Answer
The financial factors that actually decide whether renting or buying a house wins, beyond the simple 'rent is throwing money away' argument.
"Renting is throwing money away" is one of the most repeated pieces of financial folk wisdom — and one of the most incomplete. Buying has its own ongoing costs that build no equity at all (mortgage interest, property tax, insurance, maintenance), and a down payment sitting in home equity is money that isn't growing anywhere else. The real answer depends on a handful of specific factors, not a one-line rule.
The factors that actually decide it
- How long you'll stay. The single biggest lever — short stays favor renting because buying's transaction costs dominate; long stays favor buying as equity and appreciation compound.
- Local price-to-rent ratio. Markets where home prices are very high relative to rents tend to favor renting financially, and vice versa.
- What you'd do with the difference. The entire renting advantage in a fair comparison assumes the money not spent on a down payment gets invested — if it wouldn't be, buying looks relatively better.
- Appreciation vs. investment return assumptions. Neither is knowable in advance; the comparison is only ever as good as these two guesses.
Running your own numbers
Plug your actual home price, rate, comparable rent, and expected time horizon into the Rent vs. Buy Calculator rather than relying on a general rule — the right answer is genuinely different for a 3-year stay in a high price-to-rent market than for a 15-year stay in an affordable one. If buying comes out ahead, the House Affordability Calculator checks what price you could actually qualify for next.
