What the OMI range really tells you

The OMI values of the Italian Revenue Agency are ranges for an area, a property type and a period. They do not value a single flat and do not replace a professional appraisal. A fair comparison also needs condition, floor, exposure and documentation.

On the auction pages, the “below the area value” discount shows how far the minimum offer per square metre is below the minimum of the area range. A lower value does not equal an expected gain.
