Realstate market

I am currently residing in Bangalore, and was planning to purchase a flat. The flats were ranging from anywhere from 1.5 to 2cr( decent ones) Now, yesterday I came back home Patna and thought of checking the rates to my surprise it was around 1.25 to 1.75 cr ( Digha area ). And Patliputra and all were more that that. Now, I currently earns decent, kind of in top 1% maybe, I cannot gather myself to by a flat of 1cr. Who is buying all that in Patna ???? Like why such exorbitant prices😥
