Executive Summary
US mainstream consumer-facing explainer (real estate agent marketing platform) summarising the four-phase 18-year cycle framework per Homer Hoyt / Fred Foldvary / Fred Harrison / Glenn Mueller. Important because it captures how the cycle thesis has entered mainstream US real estate agent literature as of January 2026. Cites Dr Glenn Mueller (University of Denver) whose Cycle Monitor has tracked 54 metro areas across five property types for decades.
Key Claims
- Homer Hoyt’s 1933 study of Chicago land values identified the ~18-year cycle; pattern has held “remarkably consistent” since 1800. — confidence: high
- Fred Foldvary “famously used this cycle theory to predict the 2008 financial crisis years in advance… writing in 1997, he stated that the next major bust, 18 years after the 1990 downturn, would occur around 2008 if there were no major interruptions such as a global war.” ✅ Confirmed.
- NAR data: median existing home price in December 2025 = $405,400.
- Four-phase model: Recovery → Expansion → Hypersupply → Recession.
- Recovery — trough; occupancy lowest, rental growth flat/negative.
- Expansion — demand grows, prices rise, vacancy drops. Cycle’s longest phase.
- Hypersupply — supply growth exceeds demand growth; rising inventory, decelerating rent growth.
- Recession — supply >> demand; prices decline, foreclosures, distressed sales.
- Current US assessment (Jan 2026): “Most U.S. housing markets are positioned in the late expansion or early hypersupply phase, with inventory rising and price growth moderating.”
- Historical peaks cited: 1925, 1973, 1990, 2008, projected 2024–2026.
