Assumptions· 2026
  • ·Opportunity cost of down payment at assumed investment return
  • ·Home appreciation applied to full home value (leveraged return)
  • ·Mortgage interest + property tax deductibility modeled at marginal rate
  • ·Annual rent increases applied to renting scenario
When this is wrong
  • ·Transaction costs on eventual sale (agent ~5–6%, transfer taxes)
  • ·Maintenance and capex reserves (typical 1–2% of value/yr)
  • ·Rent control or rent stabilization rules limiting rent growth
  • ·Loss of liquidity and mobility option value from homeownership
Example: Moving to Denver, 3-year horizon

Jordan, 29, data analyst relocating to Denver for a job paying $95,000. He's comparing a $2,400/mo apartment in Cap Hill vs buying a $480,000 condo in Washington Park. He expects to stay 3 years before possibly moving to Seattle.

  • Home purchase price: $480,000
  • Down payment: $48,000 (10%)
  • Mortgage rate: 7.25% 30-yr fixed
  • Monthly rent (alternative): $2,400
  • Annual home appreciation: 3.5% (Denver 10-yr avg)
  • Closing costs (buy): $14,400 (3%)
  • Selling costs at exit: 5.5% agent + transfer tax
  • Time horizon: 3 years
Break-even horizon
~6.2 years

Takeaway: At 3 years Jordan comes out ~$31,000 ahead renting after accounting for sunk closing and selling costs. Denver's appreciation helps but doesn't close the gap in under 6 years. If he's confident he stays 7+ years, buying wins by ~$85k. Short horizons almost always favor renting unless appreciation outpaces historical norms.

When this calculator is wrong
  • Home-price appreciation is highly local

    National averages since 1987 are ~4.6%/yr (Case-Shiller). A condo in a mid-sized Rust Belt city may appreciate 1–2%/yr while a comparable unit in Austin appreciated 12%/yr from 2018–2022. The break-even year shifts 5–10 years depending on your assumption — small changes dominate the outcome.

  • Transaction costs are asymmetric

    Buying incurs 2–5% in closing costs at entry and 5–8% in agent + transfer costs at exit. On a $400k home, total round-trip friction is $28,000–$52,000. If you move within 3 years, buying almost never wins regardless of appreciation.

  • Rent investment opportunity cost uses a flat rate

    The calc assumes your monthly rent savings are invested at a constant annual return. S&P 500 dollar-cost-averaged returns from 2000–2025 delivered ~8.8% real, but a 2000 or 2007 entry date compressed 10-year returns to 2–4%. Sequence-of-returns risk is not modeled.

    Compound Interest Calculator
  • Tax deduction benefit is overstated for most buyers

    The mortgage interest deduction (§163(h)) only benefits you if itemized deductions exceed the standard deduction ($29,200 MFJ in 2025). At a 6.5% rate on $400k, year-1 interest is ~$25,800 — below the MFJ standard deduction. Most first-time buyers get zero incremental tax benefit.

  • Maintenance and capex costs are excluded

    Homeownership maintenance runs 1–2% of home value per year on average. A $500k home costs $5,000–$10,000/yr in maintenance — $417–$833/month that renters do not pay. This cost is not included in the default "buy" payment.
