Let's try to calculate the rate for the traditional way: y = (0.07*100000 + (x-100000))/x => y=4000/x + 0.03( L0 e4 b; y# C) O) K! w
& U$ ?2 B. S Ocomparing 2 realtors using above formular, you will see : 1) if total sale value (x in the formular) > 400,000, traditional realtor < 0.04, then traditional is better since it's < 0.04; 2) total sale value < 400,000, 2% realtor is better since traditional one > 0.04 3) if sale value is 400,000, both are the same../ X; e6 M! _5 a7 J4 m( y$ [0 O! |& M
