Rent vs Buy a Home: True Monthly Cost Comparison

Renting trades **flexibility** for **no equity build**. Buying adds **PITI**, maintenance, closing costs, and **opportunity cost** on your down payment—but you capture appreciation and principal paydown. The breakeven horizon often sits between **3–7 years** depending on market and rent growth.

Step by step

1. Compare monthly cash flow

Rent payment vs PITI + HOA + maintenance (often 1–2% of home value per year). Use realistic insurance and tax estimates.

2. Add one-time buy costs

Closing costs, moving, initial repairs. Amortize over your expected stay if comparing to multi-year rent.

3. Model opportunity cost

Down payment could earn elsewhere. Buying wins more when appreciation + principal exceeds rent inflation and foregone returns.

Rent vs buy

Short stays favor rent; long stays with stable income often favor buy in balanced markets.

  • Rent: Lower upfront cash; predictable monthly; no maintenance equity.
  • Buy: Equity build; tax benefits (jurisdiction-dependent); illiquid; transaction costs.
  • Mobility: Rent wins if you may relocate within 2–3 years.
  • Rate environment: High mortgage rates raise buy cost; rent may lag until leases reset.

Common mistakes

  • Ignoring maintenance and insurance
  • Comparing rent to P&I only, not full PITI

FAQ

Is buying always better than renting?

No—high prices, short tenure, or weak job mobility can favor rent.

What is the 5% rule?

A quick heuristic: compare annual rent to ~5% of home price (cost of ownership proxy)—not a full model.
