Putting the incoherent bits and pieces into a probable scenario, Marthe48 is house/apartment hunting, is surprised by market rental rates, ASSumes they are jacked up out of greed and to ward off undesirable tenants instead of rates that provide a reasonable profit after mortgages, taxes, upkeep, regulations compliance costs, and occasional deadbeats.
If I were a landlord and knew about Marthe48's attitude, there is no way in Hades I'd rent to him/her. (S)He would all but certainly turn out to be the tenant from Hell.
