Ultra-expensive home prices are falling beyond their core. Where next?
An independent exercise, not a statement by the video creator or verification of every claim in the video.
The arithmetic and assumptions behind annualizing weekly declines
Assuming an identical change every week, compounding -0.4% over 52 weeks gives about -18.8%; -0.5% gives about -22.9%. These differ from the video’s annual -30% explanation. Even this arithmetic cannot turn one week into an actual annual forecast. An individual sale’s decline from its peak and a regional index’s weekly change differ in coverage and period, so similar numbers do not establish the same phenomenon.
Check for yourself
- Do the compared homes share area, floor and sale terms, with no cancellation?
- Do the index geography and individual transaction periods align?
- What supports assuming that the weekly decline persists?
Limits of application
-0.4%, 52, -18.8%, -0.5%, -22.9% and -30% compare arithmetic with the broadcast explanation. They are rounded values, not an annual forecast verified against actual sales or indices.
- What to look for
- Check comparability, financing constraints and policy timelines between an individual luxury-home transaction and a broader downturn thesis.
- Why it matters
- Align comparable transactions and periods while separating listings from sales and occupancy duties from changes in rental stock to examine the assumptions behind a bearish forecast.
Timeline
5 segmentsThe speaker uses earlier and lower prices at PHOZES Hangang to discuss luxury weakness. Original filings, cancellations, floors, areas and sale terms were not independently checked; asking prices and transactions for different homes are not combined as one return. Substitution across locations is an economic interpretation, not proof of fixed neighborhood rankings or inevitable spillovers.
