"Renting is throwing money away" is one of personal finance's most expensive myths. Sometimes buying wins big. Sometimes renting wins big. The difference is math, not morality.

The 5% rule

Research popularized by Ben Felix frames it cleanly: the unrecoverable costs of owning — property tax, maintenance, and the cost of capital — run roughly 5% of the home's value per year. (That 5% is 1% property tax + 1% maintenance + ~3% cost of capital; adjust for your market.)

So for a $500,000 home, owning costs about $25,000/year ($2,083/month) in money you never get back — before a dime of principal. If you can rent an equivalent place for less than $2,083/month, renting is likely the better financial deal. If rent is $2,800, buying probably wins.

A quick version: multiply annual rent by 20. If the home price is well above that, lean rent. Well below, lean buy. Near it, it is a toss-up decided by how long you stay.

The breakeven horizon

Buying has massive upfront friction: closing costs (2–5%), selling costs (5–6% agent fees), moving. All told, 8–10% of the price evaporates in transaction costs. On a $500,000 home, that is $40,000–$50,000 you must earn back through appreciation and principal paydown before buying beats renting.

That is why the standard advice is: do not buy unless you will stay 5–7 years. In years 1–3, almost your entire mortgage payment is interest — you are "throwing money away" to the bank, just with extra steps.

What the comparison misses

Pure math ignores real factors that matter:

  • Forced savings. A mortgage builds equity on autopilot; renters must invest the difference deliberately or the math advantage evaporates.
  • Stability. Ownership locks in your housing cost (minus taxes/insurance). Rent can jump 10% a year.
  • Flexibility. Renting lets you move for a job in 30 days. Selling a house takes months and thousands.
  • Leverage and risk. A 20%-down home is 5x leveraged. If prices rise 10%, your equity rises 50%. If they fall 10%, half your down payment is gone.

Run your scenario

The honest answer is always "it depends on your numbers." Model the buying side with our mortgage calculator (include taxes, insurance, PMI — see what PMI costs), then check what price fits your income with the home affordability calculator. Compare that monthly cost to local rents, and be honest about how long you will stay.

Estimates for planning only, not financial advice. Local tax rates, HOA fees and market conditions change the math significantly.
