[ABSTRAK
Indikasi perlambatan pertumbuhan profitabilitas perusahaan properti dan real estat baik pada ROE maupun ROA sejak tahun 2013 dikhawatirkan akan terus berlanjut dan dalam jangka yang lebih panjang dikhawatirkan tidak hanya akan memberikan respon perlambatan namun juga penurunan profitabilitas hingga pada tidak tumbuhnya perusahaan. Penelitian yang dilakukan pada seluruh perusahaan properti dan real estat yang terdaftar di Bursa Efek Jakarta pada periode 2005 ? 2014 ini dilakukan untuk mengetahui bagaimana pengaruh leverage, perputaran aset, firm size, tangibility, dan pertumbuhan penjualan pada profitabilitas yaitu ROE dan ROA. Metode penelitian yang digunakan adalah analisis regresi data panel yang pada akhirnya menyimpulkan bahwa perputaran aset, firm size, dan tangibility berpengaruh secara signifikan terhadap ROE. Selain daripada itu, perputaran aset, firm size, dan tangibility berpengaruh secara signifikan terhadap ROA. Sedangkan leverage dan pertumbuhan penjualan tidak berpengaruh secara signifikan terhadap ROE dan ROA.
