Short answer. Nominal appreciation is the raw price change. Real appreciation subtracts inflation. From 1971 to 2024 U.S. median home prices grew 5.4% per year nominal but only ~1.4% per year in real terms — most of the headline growth was inflation, not housing-specific gains.
| Period | Nominal CAGR | Inflation (CPI) | Real CAGR |
|---|---|---|---|
| 1963–2024 (new homes) | ~5.5% | ~3.5% | ~2.0% |
| 1968–2024 (existing) | ~5.2% | ~3.5% | ~1.7% |
| 2000–2010 | ~2.7% | ~2.6% | ~0.1% |
| 2010–2020 | ~4.3% | ~1.8% | ~2.5% |
| 2020–2024 | ~7.9% | ~5.0% | ~2.9% |
Home prices in financial reporting are almost always nominal — the actual dollar amount paid in the year of the transaction. Comparing nominal prices across decades systematically overstates the gain because the dollar's purchasing power has fallen across the same window. Real (CPI-deflated) prices reveal what housing actually returned beyond inflation.
The 53-year reading
From 1971 (the start of the modern Freddie Mac PMMS series) to 2024:
- Nominal: existing-home median grew from $24,800 to $408,000 — a 16.5x increase, or 5.4% CAGR.
- CPI inflation: prices roughly 7.8x higher in 2024 vs 1971 — a 4.0% CAGR.
- Real (inflation-adjusted) appreciation: ~1.4% CAGR.
Most of the headline 16.5x return was the dollar losing purchasing power, not the home appreciating in any meaningful structural sense. The actual real-terms return on owning a U.S. home over five decades is roughly 1.4% per year — closer to long-run productivity growth than to equities.
Why housing's real return is so modest
U.S. housing is a tax-advantaged, leveraged, owner-occupied consumption good. The leverage (typically 4–5x at purchase) and the imputed-rent return are what make it economically productive for households despite the modest pure-price return. A 1.4% real CAGR on a 5x-levered position is roughly 7% real ROE — comparable to long-run equity returns but with very different risk and liquidity properties.
The decade-by-decade real reading
- 1970s real: ~1.8% CAGR (high inflation eroded the headline)
- 1980s real: ~0.8%
- 1990s real: ~0.7%
- 2000s real: -0.3% (boom-and-bust)
- 2010s real: ~2.5%
- 2020s real (through 2024): ~3.7%
Practical takeaway
Anyone evaluating U.S. housing as an investment over multi-decade horizons should anchor to the real-terms 1.4% baseline, not the nominal 5.4%. The wealth that homeowners accumulate over long holding periods is substantially the leverage effect plus the imputed-rent dividend, not pure price appreciation. The affordability through the decades explainer reads the joint price-and-rate path that determines what households actually paid.
