The adjustment factor is the same within a geographic area, even though the actual sales value can vary a lot due to e.g. differences in the location of the owner-occupied dwellings (amenity), which are not reflected completely in the official real estate valuations. The preliminary year are dependent primarily on sales data for real estate. When the final year are calculated all of the sources are available. Experience from 2019 and 2020 shows that the preliminary year tends to underestimate the total market value of the final year.
To calculate the market value of real estate, the statistics used a correction factor, which adjusts the level of the value, so it corresponds to the market value. Use of correction factors are an average which does not take into account the individual differences between the properties.

The market value may depend on factors other than the property's location and price level. Examples of other factors which affect the market value include distance to the coast (especially holiday cottages), distance to shops and public transport, the age and condition of the property.
