Housing Boom-Bust Cross-Cut Audit — All 20 Metroplexes

Date: 2026-05-22 Purpose: Audit completeness of housing data across the 20-metroplex dataset, with focus on the COVID-era boom (2020-2022) → current correction pattern that Ranjan flagged. Method: Pulls housing-section data from each metroplex file and structures it for canon-writing use.


The COVID-era housing boom hierarchy (2020-2022)

Across the 20 metros, six distinct boom patterns emerged. Knowing which pattern each metro followed is the key to reading current data.

Boom pattern Metros
Tier 1 boom (40%+ gains, now correcting) Austin, Phoenix, Nashville, Las Vegas, Boise (not in set)
Tier 2 boom (25-40% gains, mixed) Charlotte, Tampa (not in set), Atlanta, Denver, Miami, DFW
Tier 3 boom (15-25% gains, holding) Houston, San Antonio, Seattle, Boston
Counter-cyclical (declined during COVID, recovering now) Manhattan/NYC core, SF Bay city core
Steady/didn't boom (Midwest urban) Chicago, Philadelphia (not in set)
Suburban boom inside non-boom metros NJ commuter belt, Queens/Brooklyn within NYC, Bergen, Cook County collars

New cross-cutting findings from the enhancement pass

Peak years cluster tightly in mid-2022 across all boom metros: - June 2022 peaks: Houston ($353,995), San Antonio (~$340K), Phoenix (June peak) - May 2022 peaks: SF Bay (Case-Shiller 383), Houston average ($438,301) - April 2022 peak: Denver ($616,500) - July 2022 peak: Seattle (ZHVI $978K) - April 2022 peak: Charlotte boom - March 2025 secondary peak: Las Vegas (post-COVID slow-bleed pattern)

Implication: housing-cycle peaks across the 20 metros are bunched in a 4-month window (April–July 2022). The synchronous nature of this peak is itself canon-worthy — it argues against "regional housing dynamics" and for "national capital regime change" as the structural cause.

% off peak gradient (post-enhancement, all measurable): - Sharpest drops: Boulder -25.9%, Seattle -13.3% (real terms deeper), San Antonio -9.7% - Moderate: Houston -6.2%, SF Bay -5-6% (with bifurcation) - Mildest: Denver -1.9%, Phoenix mid-tier -10-15% (segment-dependent)

Sub-metro inversion confirmed across all 16: - Sunbelt: outer suburbs/exurbs weaker than urban cores (Collin County, Phoenix outer, Sugar Land, New Braunfels, Aurora) - Coastal/legacy: inner cores weaker except for AI-driven outliers (Oakland weaker than SF, Hayward weaker than Bellevue) - NYC pattern: commuter belt outperforms Manhattan recovery - Chicago pattern: collar weaker than core (inverse-Sunbelt)

This sub-metro inversion is the cleanest structural read that the COVID flight-to-suburbs pattern has fully unwound and the geography is now arguing against itself.


Cross-cutting housing insights (canon-worthy)

Insight 1: Days-on-market is the cleanest universal indicator. Every single metro shows DOM increasing YoY. The magnitudes: - Nashville: 98 vs 64 (+53%) - Boston: 33 vs 22 (+50%) for city - Las Vegas: 38 vs 24 (+58%) - Atlanta: 70 vs 57 (+23%) - San Antonio: 99 (+13%) - Charlotte: 55 vs 51 (+8%) - Denver: 56 (+18%) - Seattle: 12 vs 9 (+33%)

DOM is rising faster than prices are falling — buyers have time, sellers don't have leverage. That's the structural shift.

Insight 2: Three patterns explain all 20 metros. - Sunbelt boom-bust (DFW, Phoenix, Austin, Vegas, Nashville, Charlotte, Atlanta, Miami): Strong COVID boom → softening 2024-2026, with sub-area divergence (outer-ring weaker than inner where in-migration still works) - Counter-cyclical (NYC, SF Bay): Declined during COVID, recovering now (AI in Bay, post-WFH normalization in NYC) - Steady non-boom (Chicago, Houston, San Antonio, Boston, Seattle): Mild appreciation, no bubble, but still seeing DOM and inventory pressure

Insight 3: The condo segment is the leading-edge crack in every metro that has condo stock. - Miami: 12.9 months condo supply, post-Surfside special assessments - Boston: Sales >$3M -35% YoY, condo DOM +18.5% - Charlotte: Townhomes -2.2%, 9 of 12 months YoY decline - Atlanta: Townhomes/condos absorbing sharpest pressure - Denver: Condos/townhomes have greatest softening - NYC: Manhattan condo +2.2% (resilient) vs FiDi office >24% vacancy (cracked)

Insight 4: Inventory YoY is the second-most-universal indicator after DOM. - Las Vegas: +56% (highest) - Charlotte: +12.7% to +19.2% - DFW: 10+ months supply statewide - Atlanta: +5.1% to +14.6% - Houston: +6.5% - Denver: +8-9%

Insight 5: City vs suburban inversion is the structural surprise. - Sunbelt metros: outer rings (Collin County, Phoenix suburbs, Charlotte townhomes) softer than urban cores - Chicago: collar counties (DuPage, Lake) weaker than Cook County - NYC: commuter belt (NJ, Queens) outperforming Manhattan-then-recovering - This inverts the 2020-2022 "flight from cities" pattern. The COVID outward-migration peaked; now the unwind has the geography backwards.


Recommendation

Dataset is strong enough to support canon writing without further research. The 3 "10/10" files (Austin, Vegas, Miami) plus the 9-10/10 tier (NYC, Phoenix, Charlotte, Nashville, Boston, Chicago, Atlanta) give 11 of 20 metros at canon-citation quality on housing alone.

The 5 weaker files (Seattle 5/10, Denver/San Antonio/SF Bay/DFW at 7-8/10) have enough data to be usable; the gaps are specifically peak-comparison numbers, recoverable from Zillow Research Data (free CSVs) in subsequent passes.

The cross-cutting insights at the bottom of this file (DOM is the universal indicator, three boom patterns, condo segment leading-edge, inventory YoY, city-suburb inversion) are immediately usable in canon writing — they're the empirical patterns that the framework reading anchors on.
