Documentation on methodology
The indices are calculated based on the net vendor transaction prices (excluding transfer
duties, notary's fees and agency fees). The methodology for the calculation of these
indices is based on hedonic models accounting for the price of a dwelling based on
its characteristics.
Using these models, the value of a reference second-hand dwellings stock is estimated
at the prices for the current period. An index is defined as the relationship between
the current value of this stock and its value during the base period (since september
2018: Base = 100 on average in 2015).
