previously owned but unoccupied condominium
Real estate term for a condominium that was built over a year ago but has never been lived in; essentially new but legally second-hand.
Previously owned but unoccupied condominiums are often priced lower than brand-new ones.
The previously owned but unoccupied condominium I viewed showed no signs of anyone having lived there.
Compound of 新 (new) and 古 (old), reflecting the property's dual status as legally second-hand but physically new. The exact origin is uncertain, but it is a modern real estate coinage.
