Executive Summary
UK landlord-focused consumer explainer. Notable for the self-fulfilling prophecy argument — as more investors adopt the 18-year framework, the model’s predictive power may be reinforced by collective positioning. Provides a clean summary of Harrison’s phase structure from a UK property-investor perspective written in 2021 (two years from the cycle ending, in Harrison’s count).
Key Claims
- Harrison “rose to fame for predicting the 2007-08 financial crash as early as 1998.” — confidence: medium
- Boom and Bust (2005) demonstrated 18-year cycle across 200 years of UK house price data. — confidence: high
- UK crashes supporting cycle: 1953–54, 1971–72, 1989–90. — confidence: high
- Phase breakdown:
- Post-crash recession: 3–4 years (supply glut draws prices down)
- Recovery: 6–7 years (confidence returns, prices creep up)
- Mid-cycle correction: 1–2 years (investor nerves)
- Boom: 5–6 years (stimulus + low credit costs = strong growth)
- Peak + crash → new cycle
- Author estimates UK entered boom phase ~2019–20, coinciding with 8.6% YoY house price growth and 95% mortgages.
- If cycle holds, “3–4 years more of booming house price growth before the inevitable crash” and prices possibly +25% from 2021 levels.
