US home prices continue to rise quarter-over-quarter through the first half of 2027.
Despite elevated rates, limited inventory has kept upward pressure on prices. Resolves true if national price indices post sequential gains in Q1 and Q2 2027.
Across 6 frontier models answering independently, the panel leans yes: the median is 68%.
They do not agree: Qwen puts it at 79% and Claude at 48%, 31 points apart. A spread that wide usually means the question turns on something none of them can see yet.
Nothing is settled until 2 Nov 2027, when the outcome is checked against sources and every number above gets a permanent score.

Lock-in effect keeps inventory constrained; QoQ national declines are historically rare outside credit crises.
- Since 2012, national indices (Case-Shiller, FHFA) posted QoQ gains in ~90% of quarters; declines required the GFC-level credit event.
- The mortgage lock-in effect (homeowners holding sub-4% rates) shows no sign of breaking by mid-2027, keeping supply artificially tight.
- A recession with rising unemployment triggering forced sales would be the main threat, but even 2022's rate shock only produced flat-to-slightly-negative quarters in…

Persistent structural supply shortages and seasonal spring buying tailwinds make consecutive QoQ home price gains likely through mid-2027.
- Q1 and Q2 almost always post positive quarter-over-quarter price growth due to strong spring buying seasonality across major indices.
- The 30-year fixed rate lock-in effect continues to suppress existing home listings, keeping inventory below historical norms.
- A sharper labor market contraction lifting unemployment above 5.5% before early 2027 is the main risk that could induce price drops.

Inventory and mortgage-rate paths will determine whether affordability finally outweighs the persistent supply shortage.
- National indices have risen in most quarters outside recessions; two consecutive gains is the historical default over a nine-month horizon.
- Builders, sellers and the Fed need not coordinate, but rates near 7% plus rising unemployment could trigger a broad demand pullback.
- A sharp recession or a sustained mortgage-rate jump above recent highs would move this estimate materially lower.

Both Q1 and Q2 2027 national indices (FHFA/Case-Shiller SA) post positive sequential changes.
- Fed funds path and 2026-27 labor data must keep mortgage rates from re-spiking above ~6.5% while unemployment stays under 5%.
- Post-GFC base rate is ~80% of quarters up outside recessions; spring seasonality and chronic underbuilding put this case near that rate.
- A 2026 inventory surge from delayed listings or a sudden jobs slump would most reverse the call.

Turns on whether the Fed cuts enough by mid-2027 to thaw supply without killing demand.
- FHFA and Case-Shiller both posted sequential gains through 2026 despite 6%+ mortgage rates, so the base rate for Q-over-Q increases is already high.
- Inventory stays near historic lows because lock-in effects deter sellers; that scarcity, not demand strength, is what keeps clearing prices rising.
- A Fed easing cycle into 2027 would lift affordability and demand faster than it unlocks supply, reinforcing gains; a sharp recession or 7%+ rates would break the streak.

Hinges on mortgage rates and inventory through mid-2027, since national indices have mostly risen q/q for a decade but growth is now near flat.
- Case-Shiller/FHFA indices have posted q/q gains almost every quarter since 2012 except brief dips in 2022-2023, giving a high structural base rate.
- Recent data shows price growth has decelerated sharply in 2024-2025 with some metros flat or declining, so the national composite is now near a tipping point.
- A recession, continued high rates, or rising inventory from forced sales could push national q/q prices negative in one of the two quarters, which would resolve this…
