But rents aren't the same as property values (though they are linked). Rents could go down while the value of the underlying land goes up (extreme example - build a high-rise apartment, land and building value goes up, even though the rent for each unit comes down). And the apartment market and SFH market are linked but also not exactly the same.

Also agree it's difficult/impossible to know for a single piece of real estate. And impossible to know for sure since the market is complex (impacted by rates, other policy decisions, etc)
