Same address.
Different lives.

APSPECT measures the invisible living environment of every apartment home — twelve physical dimensions, one comparable score.

The market prices the address — not the life inside.

Housing is the largest purchase of an ordinary life. Yet buyers decide with a broker's impression and one visit on a sunny afternoon. Within a single complex we measured, homes range from a full river view to none, and from 3,523 to 119 annual sunlight hours.
