Let's try to calculate the rate for the traditional way: y = (0.07*100000 + (x-100000))/x => y=4000/x + 0.039 [- Y# Z! Z4 l( L6 [2 M+ b4 O9 E( b

comparing 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..& @.

Note: above comparison is based on the assumption: 2% realtor means 2% for each side realtor (i.e., total 4%)
