Housing is your biggest FIRE lever.
Your housing cost — and the wealth you build or preserve — is likely the single largest variable in your financial independence timeline. A $500/month difference between renting and buying doesn't just affect your budget today. Compounded over 10–20 years, it can move your FIRE date by years.

How we calculate these estimates
▼
- Mortgage P&I: Standard amortization formula using monthly compounding.
- PMI: 0.5% annually of original home price, auto-removed when loan balance reaches 80% of original home price.
- Closing costs: 3% of home price upfront; selling costs: 6% of appreciated home value at end of horizon.
- Tax benefit: Simplified estimate. Applied only when mortgage interest + property tax exceeds the 2026 standard deduction ($32,200 MFJ / $16,100 single). This is not personalized tax advice.
- Opportunity cost: Down payment + closing costs invested at specified annual return, compounded annually.
- Home appreciation and rent increases applied annually from year 2.
- Renting wealth: If monthly renting cost is lower, the difference is assumed invested monthly at the specified return rate.
- Time value of commute: (daily minutes × 2 × 22 working days) ÷ 60 = monthly hours × hourly rate.
