Owned house (single-family house or apartment)

I am asking this question to those who have moved since October 1 of last year and are currently living in a home they own, or who have purchased, added an extension, remodeled the house, or changed the name of the land or house they are currently living in.

1st - 6th waves (Housing construction period starts from 2nd wave)

Year the land was acquired	year the house was acquired	Housing construction period
Q375A	Q376A	Q376B

7th wave -

Year the land was acquired	year the house was acquired	Housing construction period
Q889	Q890	Q891

notice

Up to the 6th edition, “year the house was acquired” was asked in Q376A and “time of housing construction” was asked in Q376B.

In the questionnaire, the question is asked in the original year, but in the records, it is converted to the last two digits of the Western calendar.
