Elemzésemben a budapesti albérletárakat magyarázom a gyakran használt alapvető leíró tulajdonságok, mint például alapterület, szobák száma vagy eerkély mérete, mellett az adott albérlet területi tulajdonságaival. Ilyen elemzett változók a legközelebbi metrótól vonatállomástól esetleg egyéb tömegközlekedési eszköztől vagy bevásárlóközpontól számított távolság, vagy az adott lakás kerülete. Az elemzéshez az Ingatlan.com oldalon található hirdetéseket használom, és azt az Openstreetmap által szolgáltatott adatokkal összeillesztve elemzem.
