The first step in solving any problem is to know the problem. Despite the issue of land and housing rent
being heard as a major challenge in the cities, villages and natural lands of the country and the severe
damages caused by it; A suitable and coherent policy and solution has not been considered for it. One of
the reasons for such conditions is the lack of theory and accurate theory regarding the origin, function and
reproduction of this process. The current research has been carried out with the aim of creating a theory
and a comprehensive theory of usable rent and generalizing it to the construction of land and housing in
Iran. The method considered for this research was qualitative (using the grand theory model). The type of
research is fundamental and has the purpose of increasing knowledge. The research tool of in-depth
interview, the statistical population of researchers in the field of land rent and housing, the sample number
was 10 people (loss owners in the field of land rent and housing). The analysis of the interview has also
been done with MAXQDA software. The results have been analyzed in two lexical levels and research
categories. The results of the research indicate that in Iran, what is used as land and housing rent are
expressions such as land consumption, mountain consumption, forest consumption, etc., which are rooted
in economics; Therefore, solutions such as bringing under control the category of ownership, as examples
of ownership such as endowments, obliging the organization of endowments for charitable affairs to behave
lawfully, orienting this use and this institution towards public good and collective benefit can be presented.
