From the dataset abstract

HSY prepares an annual presentation on the maximum prices of lots applied in the Helsinki metropolitan area in housing production supported by the Housing Finance and Development Centre of Finland (ARA). The objective of this work is to define an area-specific, cohesive and consistent upper limit for a reasonable price level. It acts as a guideline to the pricing of lots granted for ARA production, in accordance with the objectives of ARAVA and interest subsidy legislation. This regional recommendation price has been traditionally also used as a general guideline for defining reasonably priced lots.

Price information is presented on the map by means of the administrative regional divisions of the municipalities (sub-areas of Helsinki, small areas of Espoo, districts of Vantaa, and Kauniainen as a whole municipality), separately for apartment building lots and detached house lots. More specific application instructions for analysis of the lot’s location and quality factors, for example, are available for the map.
