The rent index covers quality-adjusted contracted rents for condominium-type buildings generally, not this address; the land figure is an average across all official reference points in the ward, not an appraisal of this address; the price index is a nationwide statistical series for Tokyo. None of them guarantees future rent, value or performance.
