Prior state
Housing wealth was the principal store of middle-class savings and the main axis of intergenerational inequality, with vacancy treated as a rural curiosity in Japan and a non-issue elsewhere.
Material change
Deaths among the largest owner-occupier cohorts peak, transferring an unprecedented share of national housing stock to heirs who already own homes, live elsewhere, or cannot afford the maintenance, tax, and — increasingly — insurance costs. In weak-market regions, the transfer converts inherited property from windfall into abandonment, and the state becomes the residual owner.
Why now
The cohorts concerned reach the ages at which mortality is concentrated during this decade, not before. Japan's death total peaks around the interval's start; the American, German, and Italian equivalents follow within it.
Mechanism and resistance
Heirs decline or abandon low-value property; municipalities face rising shares of untaxable, unmaintained stock; land banks, compulsory-registration regimes, and demolition subsidies expand from Japanese and American Rust Belt precedents into Southern Europe. Simultaneously, in high-demand metros the same wave concentrates ownership further among heirs who already had it, making inheritance taxation the sharpest fiscal argument of the decade. Resistance comes from property-owning electorates, from rural municipalities whose tax base is the stock being written off, and from the legal difficulty of extinguishing fragmented title.
Consequences
Wealth divides less between owners and renters than between those who inherit in liquid markets and those who inherit in dying ones. Regional depopulation accelerates where inherited housing cannot be sold, and demolition rather than construction becomes the visible public works of provincial Japan, Korea, and parts of Southern Europe.
End state
Housing policy in aged societies is reorganised around disposal, consolidation, and forced maintenance rather than around production, and inheritance is a first-order axis of political conflict.
Observable test
Vacancy and abandonment rates in non-metropolitan areas of at least three high-income aged societies rise past the point where public demolition or land-banking programmes exceed public housing construction in cost; national inheritance or property tax regimes are materially rewritten in at least two of them.
Disconfirming sign
Migration, household fission, or subdivision absorbs the released stock quickly enough that vacancy stabilises, and inheritance taxation remains politically untouched.
