How much do building age, area and walking time move the price per ㎡?

We took the coefficients of the statistical model () fitted to actual transactions in each municipality and summarized them by prefecture, weighted by the number of transactions. They are multipliers with the price per ㎡ of a reference property (for example 20 years old, a 60㎡ used condominium, an 8-minute walk) set to 1.0. They show the average tendency with other conditions held equal, not the price of an individual property.

Color and numbers show how many times the reference property’s price per ㎡ you get when building age and area change together. The values multiply the effects of age and area; any effect specific to the combination (interaction) is not in the model. The four prefectures use the same color scale.

How to read

Building age: the newer the building, the higher the price per ㎡, and it falls as the building ages, but not at a constant rate. Around 40 years the model sometimes shows a tendency to level off.
Area: in general, the larger the area, the lower the price per ㎡ (because the total amount becomes larger). The slope differs by prefecture and type.
Walking time to the station: the closer, the higher, with the difference becoming smaller from around a 10-minute walk.
The curves are drawn from the median of the models (three or more) of municipalities with enough transactions in the same prefecture and type. Parts beyond the range the model fits (for example, building age over 70 years) are not shown.
